40G QSFP+ Breakout Cables vs. QSA Module

40G QSFP+ Breakout Cables vs. QSA Module

When one end of the network is running on a 40 Gigabit platform, and the other end of the network is running at lower speeds such as 10 Gbps, migration is required. Using fan-out technology and QSA are two different methods to achieve the migration between 40 Gigabit Ethernet and 10 Gigabit Ethernet. But which is better?

Expands the 40G Data Pipe into 4x10G Lanes With Breakout Cables

40G QSFP+ to 4×10 SFP+ breakout cables including direct attach copper cable (DAC) and active optical cable (AOC) can take a 40 Gigabit physical interface and break it out into four SFP+ interfaces, converting the downlink 40G port of ToR (Top of Rack) access layer switch into 4x10G channels then connect to the cabinet server port. Thus, they are considered as the most cost-effective solution for 10G to 40G migration in short-reach interconnect environment.


Converting a QSFP+ Port to an SFP+ Port With QSA

QSA (Quad Small Form-Factor Pluggable Adapter) is the first solution for the QSFP+ to SFP+ conversion challenge in the world. It enables smooth connectivity between devices that use quad lane ports and 10 Gigabit Ethernet hardware that uses SFP+ based cabling. In other words, with QSA, you can effectively use a QSFP or QSFP+ module to connect to a lower-end switch or server that uses an SFP+ based module.

QSA module is built in a QSFP+ form factor with a cage for SFP+ module at the back. When inserting an SFP+ into a QSA connected to a 40 Gigabit port, QSA acts as an interface for the SFP+. This interface enables you to directly plug in an SFP+ originating at a 10 Gigabit Ethernet port on a switch or server.


40G QSFP+ to 4×10 SFP+ Breakout Cables vs. QSA

As mentioned above, we can use QSFP+ to 4x10G SFP+ breakout cables to split a 40 Gigabit port on a switch or a server into four 10 Gigabit ports. Or use QSA to convert a QSFP+ port to an SFP+ port. However, which one is better for an optimal ROI (Return on Investment)? Obviously, the former is more cost-effective for these reasons:

  • Technology and products of QSFP+ to 4x10G SFP+ breakout cables are more mature in today’s market. Users can even use the 3rd party product without considering the problem caused by vendor lock-in.
  • QSFP+ to 4x10G SFP+ breakout cables split the 40G channel into 4x10G channel which provides four times more data transfers compared to a QSA that just provides connectivity only for a single 10G connection.
  • QSFP+ to 4x10G SFP+ breakout cables support both DAC and optical connectivity, and are cheaper than the expensive QSA.

40G QSFP+ to 4×10 SFP+ breakout cables and QSA modules can both be used for migration between 40G and 10G ports. But considering cost, performance, and compatibility actual environment, the 40G QSFP+ to 4×10 SFP+ breakout cables seem to be better. FS.COM offers a wide range of 40G QSFP+ to 4×10 SFP+ breakout cables including QSFP+ to 4×10 SFP+ DACs and QSFP+ to 4×10 SFP+ AOCs, which are 100% compatible for various platform, like Cisco, HPE, Juniper, and so on.

Media Types for 10 Gigabit Ethernet

Media Types for 10 Gigabit Ethernet

10 Gigabit Ethernet: 10g-switchesToday, the Ethernet cabling systems market is dominated by 10G links. Several physical media types are available to support 10 Gigabit Ethernet applications, including 10GBASE-CX4, SFP+ DAC, fiber optics, and 10GBASE-T (using twisted pair, RJ-45 connectors). In this post, they are introduced one by one.


CX4 is the first 10G copper standard published by 802.3 (as 802.3ak-2004). It offers the advantages of low power, low cost and low latency and is specified to work up to a distance of 15 meters. But it is not widely used today due to its large cable and inability to run at longer distances.

10GBASE-SFP+ Direct Attach

10GBASE-SFP+ direct attach refers to the small Form-factor Pluggable (SFP+) passive assemblies that use low power and have smaller cables than 10GBASE-CX4. They are widely used in today’s 10G network interconnection. However, from a structured cabling viewpoint, they have a limited distance (up to 10m), are not interoperable between equipment vendors, and are not as flexible or cost effective as 10GBASE-T.

Fiber Optics

Fiber optics options such as 10GBASE-SR (short range SFP+ Fiber) offers the benefit of working over longer distances and low power, as well as providing a smaller cable profile. But the high costs of fiber active equipment makes it an option that not all end users can justify for applications up to 100 meters. As an alternative to 10GBASE-SR, SFP+ AOC (Active Optical Cable) seems like a new and more cost-effective choice for users.

Note: 10G transceivers also include 10G X2, 10G XFP, and 10G XENPAK. But the most commonly used form factor for today’s 10 Gigabit Ethernet network is SFP+.

IEEE 802.3an (10GBASE-T)

10GBASE-T standard defines connections over twisted pair cable, using RJ-45 connectors. CAT 6 is can carry 10GBASE-T for shorter distances when qualified according to the guidelines in ISO TR 24750 or TIA-155-A. However, it is not recommended for new installations intended to support 10GBASE-T networks due to performance issues. CAT 6A technology can deliver 10G performance up to 500 MHz and at a distance of up to 100 meters. When comparing costs per port of equipment, maintenance, and assembly of 10 Gigabit Ethernet, it is significantly more cost-effective than other technologies. It is considered as the preferred cabling option for 10GBASE-T due to its flexibility, low cost, reach, and backwards compatibility.

A Complete Guide of Installing or Removing Transceiver Modules (Part I)

A Complete Guide of Installing or Removing Transceiver Modules (Part I)

After learning more about a variety basic or conclusive knowledge of transceiver modules these days, I believe you must have a new understanding or a deeper perception on the transceiver modules. In fact, that’s just a tip of iceberg. My blog will continue to bring more information about the transceiver modules, also the other knowledge of fiber optic communication, network, telecom etc. to all of my friends who like this field and like my blog. Since we discuss so much about the theories of the transceiver modules, today, I prefer to talk about something practicle, for instance, some knowledge about installing or removing different kinds of transceiver modules.

As we know, the commonly used transceivers include the following 8 types:

The following content will cover the knowledge of installing or removing for these types of transceiver modules, namely today’s main topic. But first of all, I want to talk about some preparations and considerations before starting the main topic.

What equipment should we need to install a transceiver module?
When installing a transceiver module, some tools you should need in order to make your installation go well. The following is a list of such tools which are recommended:

  • A Wrist strap or similar personal grounding device designed to stop ESD occurrences.
  • An Antistatic mat or similar which the transceiver can be placed on.
  • Fibre-optic end-face cleaning tools and inspection equipment.
  • A flat head screw driver is require to install a XENPAK transceiver module.

What should we need to know before or during installing or removing a transceiver module?
In order to ensure the safety and avoid leading the unnecessary losses, there are some items which we should consider before and during installing and removing the transceiver modules.

  • To preventing the cables, connectors, and the optical interfaces from damage. We must disconnect all cables before removing or installing a transceiver module.
  • Please be aware that the regular removal and installation a transceiver module can shorten its useful life. Thus, transceivers should not be removed or inserted more often than is required.
  • Transceiver modules are sensitive to static, so always ensure that you use an ESD wrist strap or comparable grounding device during both installation and removal.
  • Do not remove the dust plug from the transceiver slot if you are not installing the transceiver at this time. Similarly, we must use the dust plug to protect the optical bore if we don’t use the transceivers.

How to Install or Remove Transceiver Modules
1. How to Install or Remove GBIC Transceiver Module
GBIC Installing Steps
step 1: Firstly you should attach your ESD preventive wrist strap to your wrist to prevent ESD occurrences.
step 2: Remove the GBIC transceiver from its protective packaging.
step 3: Verify that the GBIC transceiver module is the correct model for the intended network.
step 4: Using your thumb and forefinger, grip the sides of the GBIC transceiver and carefully align it with the GBIC socket opening on the device.
step 5: You can now carefully insert the GBIC transceiver module through the socket flap and slide it into the GBIC socket. A click will be heard once the GBIC is locked into the socket. Please ensure that the GBIC is inserted carefully straight into the socket.
(Please note: you should keep the protective dust plugs in place until making a connection. You should also inspect and clean the SC connector end faces immediately prior to making a connection.)
step 6: The dust plugs from the network interface cable SC connectors can now be removed, ensuring that these are saved for later use.
step 7: Next, inspect and clean the SC connector’s fiber optic end faces.
step 8: Remove the dust plugs from the optical bores on the GBIC transceiver module.
step 9: You can now attach the network interface cable SC connector to the GBIC.

GBIC Removing Steps
Please be aware that GBIC transceiver modules are static sensitive so you should always use an ESD wrist strap or similar grounding device when coming into contact with the device. Transceiver modules can also reach high temperatures so may be too hot to be removed with bare hands.
step 1: Disconnect the cable from the GBIC connector.
step 2: Release the GBIC from the slot by pressing the two plastic tabs located on either side of the GBIC (They must be pressed at the same time).
step 3: Once released carefully slide the GBIC straight out of its module slot.
step 4: The GBIC transceiver module should now be placed safely into an antistatic bag.

2. How to Install or Remove SFP Transceiver Module
SFP/SFP+ Installing Steps
SFP modules can have 3 different types of latching devices which secure the SFP into the module socket, so please determine which latching device your module has before installation or removal of the device.
step 1: Firstly you should attach your ESD preventive wrist strap to your wrist as well as to the ESD ground connector. A metal surface on your chassis is also acceptable.
step 2: Next, remove the SFP transceiver module from its packaging.
(Please note: You shouldn’t remove the optical bore dust plugs yet.)
step 3: Check the SFP transceiver to ensure that it is the correct model for the network
step 4: Locate the send (TX) and receive (RX) markings. These will allow you to identify the top of the SFP transceiver module.
(Please note: Certain SFP transceiver modules may represent the TX and RX marking with arrowheads. The direction of these will allow you to determine the send and receive.)
Pointing from the SFP transceiver module connector = Transmit/TX
Pointing toward the connector = Receive/RX
step 5: Align the SFP transceiver module with the module port.
(Please Note: Devices can have different SFP module socket configurations. It is possible to have either a latch-up or a latch-down orientation. Firstly make sure that you are installing an SFP transceiver module with the correct latch orientation for your device.)
step 6: Insert the SFP Transceiver Module into the socket until you feel the SFP’s connector latch into place. Ensure that you press the SFP firmly into the slot using your thumb.
(Please note: For those SFP transceiver modules which have an actuator latch, you must press on both the transceiver faceplate and the actuator button to ensure that the transceiver is correctly connected.)
step 7: Verify the SFP transceiver module installation. Attempt to remove the SFP without releasing the latch, if it cannot be removed then it is correctly seated. If it can be removed reinsert the SFP and press harder with your thumb, until you can verify that it is correctly seated.
step 8: You can now remove the dust plugs from the network interface cable LC connectors. You should save the dust plugs for future use.
step 9: Inspect and clean the fibre-optic end-faces on the LC connector.
step 10: You can now remove the dust plugs from the SFP transceiver module’s optical bores. As soon as this has been completed you must attach the network interface cable LC connector to the SFP.
(Please note: If you are connecting a 1000BASE-T SFP transceiver module to a copper network you should firstly insert the Category 5 network cable RJ-45 connector into the SFP transceiver module RJ-45 connector. Then Insert the other end of the network cable into an RJ-45 connector on a 1000BASE-T-compatible target device.)
step 11: Check the port status LED, if it turns green the SFP transceiver module has established a link with the target device. If the LED is off please ensure that the target device is powered on before troubleshooting. The LED will turn amber for approximately 30 seconds prior to turning green.
step 12: Reconfigure and reboot the target device if required.

SFP/SFP+ Removing Steps
Please be aware that SFP transceiver modules are static sensitive so you should always use an ESD wrist strap or similar grounding device when coming into contact with the device. Transceiver modules can also reach high temperatures so may be too hot to be removed with bare hands.
step 1: Attach your ESD wrist strap and the ESD ground connector to a metal surface on the device chassis.
step 2: Next disconnect the network cable from the SFP transceiver module connector. You should then reinstall the dust plugs on the optical bores and fibre optic cable LC connectors.
step 3: Release and remove the SFP transceiver module from the socket connector.
Mylar Tab Latch: for SFPs with a Mylar Tab Latch, you should first pull the tab in a downward direction until the SFP is released from the socket connector. Then the SFP module can be pulled directly out, ensuring not to twist or pull the Mylar tab.

Actuator Button Latch: for SFPs with an Actuator Button Latch, you should gently press the button on the front of the transceiver until it clicks. This should release the SFP transceiver module from the socket connector, following which the SFP transceiver module can be carefully removed from the module slot. This should be done straight, ensuring not to twist or bend the module.

Bail Clasp Latch: For SFPs with a Bail Clasp Latch, the latch should be pulled out and down to eject the SFP transceiver module from its socket.
step 4: The removed SFP transceiver module should now be placed safely in a protective environment such as an antistatic bag.

About how to install or remove XENPAK, X2, XFP, QSFP/QSFP+ and CFP will be continued in the next blogs. Please focus on my blog update on next Monday.

The Rapid Development of Optical Transceiver Market

The Rapid Development of Optical Transceiver Market

Several years ago, there was a report which said that the 10G/40G/100G optical transceivers would hit 1.44 billion dollars by 2014, driven by 10G SFP+ and tunable XFP modules. It is now 2014, and the forecasts have came true.

Infontetics Research released the report tracking 10-Gigabit (10G), 40-Gigabit (40G), and 100-Gigabit (100G) optical transceivers and transponders sold into the optical transport, carrier routing and switching, and enterprise markets.

In fact, the highlights of optical transceiver market have appeared years ago. Let’s make a review.

  • 10G, 40G, and 100G transceiver and transponder revenue was forecast by Infonetics Research to grow to 1.44 billion dollars worldwide by 2014, driven by SFP+ and tunable XFP technology, and by spikes in future 40G and 100G adoption.
  • Tunable XFPs would be the major 10G growth opportunity for a long time, as they eliminated inventory management issues with fixed-wavelength modules, fulfilled the need for tunability as ROADM-based networking rises in popularity, and replaced the more-costly 300-PIN format.
  • Meanwhile, SFP+ would replace XFP in the future, driven by strong growth in 850nm modules for 10-Gigabit Ethernet (10GbE) and 8/16G Fibre Channel (FC) applications.
  • Shipments of next-generation 40G long-range (LR) and short-range (SR) optical transceivers would begin in 2010, primarily for enterprise and IP router applications.
  • FiberStore 40G CFP transceiverRevenue for 40G long-reach interfaces jumped 52 percent in 2009 over 2008, to 114.6 million dollars, while revenue for 40G 300-PIN short- and intermediate-reach interfaces dropped 35 percent, driven by price erosion and demand weakness.
  • During the 2011-2012 timeframe, shipments of DQPSK transceivers were expected to outstrip those of DPSK, as the cost differential between the two drops. Worldwide revenue was forecast to grow nearly 10-fold from 2009 to 2014 for the tunable DQPSK 40G fiber transceiver.

Infonetics’ report provided in-depth analysis, market size, and forecasts through 2014 frp manufacturer revenue and units shipped for 10G, 40G, and 100G transceivers and transponders. Specifically, the report tracked the following long- and short/intermediate-reach optical transceivers/transponders.

  • 10G modules by tunable, WDM (fixed C-band), 1550nm,1310nm, and 850nm wavelengths, split by form-factor such as 300-PIN, SFP+, XFP, X2, XENPAK etc..
  • 40G modules by tunable, 1310nm and 850nm wavelengths, split by form-factor such as DPSK, DQPSK, opto duo-binary (ODB) and other, 300-PIN SFI-5, 40GBASE-LR4, and 40GBSE-SR4.
  • 100G modules by tunable, 1310nm and 850nm wavelengths, split by form-factor such as 100G DWDM, 100GBASE-LR4 (aka 4*25G non-return-to-zero, or NRZ), and 100GBASE-SR10 (aka 10*10G).

Nowadays, vendors providing products in the optical transceiver market include Cisco, Avago, JDSU, and so on. Besides these famous companies, there are also many other manufacturers and suppliers who provide compatible transceivers with much more cheaper prices.

FiberStore Provides a Complete Range of SFP+ Transceivers

FiberStore Provides a Complete Range of SFP+ Transceivers

FiberStore provides various kinds of optical communication products which are compliant with standards including Fast Ethernet (FE), Gigabit Ethernet (GE), 10 Gigabit Ethernet (10GbE), Fibre Channel (FC), SONET/SDH and WDM and operate at data rates from 100M to 100G for data-center, HPC (High-Performance Computing), access, metro-regional, wireless, and long haul net-works. They feature outstanding performance over extended voltage and temperature ranges, while minimizing jitter, elzectromagnetic interference (EMI) and power dissipation. For example, the SFP+ transceiver is one of them.

SFP+ (enhanced small form-factor pluggable) is a standardized form factor for fiber optic transceivers and is used in datacom and telecom optical links, offering a smaller footprint and lower power consumption than XFP transceivers for 10G applications. SFP+ transceivers are designed to be hot-swappable in industry-standard cages andconnectors, and offer high-speed performance in a compact package. As known that SFP was the first standardized form factor in this family, and has been used for data rates up to 4G. Then, with the need forcompact transceivers at high data rates, an enhanced version named SFP+ was developed for applications up to 10G and beyond. SFP+ transceivers are interchangeable with SFP transceivers and can be used in the same cages as SFP transceivers because of their same shape as SFP modules. What’s more, the electrical interface to the host board for SFP and SFP+ modules is a serial interface.


SFP+ transceivers’ initial standard applications focused on 8G FC, 10GbE and 10G FC, where the electrical interface to the host board is a standardized serial interface called SFI. Then, the applications have expanded to include SONET OC-192, SDH STM-64, OTN G.709, CPRI wireless, 16G FC, and the emerging 32G FC application.


SFP+ comes in 4 different versions: SR, LR, ER and ZR. Apart from the regular 10G SFP+ transceivers, FiberStore also provides the whole CWDM/DWDM spectrum for 10G SFP+. The SFP+ is also available as a BIDI optic, which has only one LC plus and will work on one single strand of single-mode fiber (SMF). SFP+ modules come with digital diagnostics monitoring (DDM) functions, which provide network managers with a highly accurate, cost-effective tool for implementing reliable performance monitoring. Let’s talk about the kinds of our SFP+ transceivers.


According to the brands, our SFP+ transceivers are divided into two big parts: compatible SFP+ and custom SFP+. FiberStore manufactures a complete range of compatible SFP+ transceivers, such as SFP+ SR, SFP+ LR, SFP+ LRM, SFP+ ER, SFP+ ZR, CWDM SFP+, DWDM SFP+, BiDi SFP+, and compatible Cisco SFP+, HP SFP+, Juniper SFP+, Netgear SFP+ etc.. The custom SFP+ transceivers can be any type up to the customers’ requirements and own the brand labeling of FiberStore.

According the different parameters and applications, our SFP+ transceivers include regular 10G SFP+, 8G SFP+, CWDM SFP+, DWDM SFP+, BIDI SFP+, 16G SFP+, Dual-Rate 1/10G SFP+ and SDH/SONET SFP+. Here are some features of them.
