What Loaded Options Can You Choose for Rack Mount Fiber Enclosures?

Rack mount fiber enclosure with various rack unit configurations, such as 1U, 2U, 4U, etc. plays a very important role in cable patching, storage and protection for rack fiber cable management in the data center. With various loaded options, they can satisfy all kinds of applications according to users’ requirements. This tutorial will present the common loaded options that you can choose for rack mount fiber enclosures.

Loaded With Fiber Adapter Panels (FAPs)

Rack mount fiber enclosures loaded with fiber adapter panels are very commonly used in fiber optic cabling, e.g. backbone cabling. The adapter panels are generally available in LC, SC and MPO/MTP, etc. According to varying quantities of adapters loaded on the FAPs, they can support up to 96 fiber distributions. For the universal 12-fiber and 24-fiber FAPs, rack mount enclosures with different rack unit configurations can hold varying quantities of them. Generally, 1U enclosure can support up to 4 FAPs, while 4U enclosure can support up to 12 FAPs. Some common FAPs options are listed below:

LC Fiber Adapter Panels

Loaded With MPO/MTP Cassettes

In addition to FAPs, rack mount fiber enclosures can also be loaded with MPO/MTP cassettes, providing secure transition between MPO/MTP and LC or SC discrete connectors. The MPO/MTP cassettes are available in LGX and HD type which can meet the demands on both universal and high-density applications. Moreover, using cassettes with TAP ports, users can easy to access and monitor the data. Similar to the FAPs option, rack mount enclosures with different rack unit configurations can hold varying quantities of cassettes. In general, 1U enclosure can support up to 4 cassettes, while 4U enclosure can support up to 12 cassettes. Rack mount enclosures loaded with MPO/MTP cassettes are an ideal solution for 10G to 40/100G migration in today’s data centers. The following picture shows us some common types of MPO/MTP cassettes.

What’s the Difference Between MTP LGX Cassette, HD Cassette and TAP Cassette?

What’s the Difference Between MTP LGX Cassette, HD Cassette and TAP Cassette?

MTP Cassettes, as an easy-to-install and cost-effective plug-and-play solution in today’s fiber optic cable patching system, are used to interconnect MTP backbones with LC or SC patching. Providing secure transition between MTP and LC or SC discrete connectors, they allow for rapid deployment of data center infrastructure as well as improved troubleshooting and reconfiguration during MACs (moves, adds and changes) by being mounted in 1U or 4U 19″ multi-slot chassis. The MTP LGX cassette, HD cassette and TAP cassette are variants of the MTP cassettes. They have similarities but also have their own unique features. As such, many users are confused by them during purchase. This post is going to understand the similarity and difference between them.


As mentioned above, the three kinds of MTP cassette have something in common. They all contain factory pre-terminated and tested MTP-LC fan-outs to deliver optimal performance and reliability. Low loss MTP Elite and LC or SC Premium versions are offered featuring low insertion loss for demanding power budget high speed networks.


I will present their differences from three aspects in this section.

The package is the most obvious difference to distinguish LGX cassette and HD cassette. The former is designed with the standard LGX package, usually being mounted in a three-slot chassis. While the HD cassette is more compact, which can be mounted in a four-slot or even five-slot chassis so that is more suitable for high-density applications. In addition, the HD cassette can be also designed with the keyed LC adapters, which help reduce unauthorized connections in the key network. It is noted that TAP cassette can be designed in LGX and HD packages.


As we know, the main application of MTP cassette is to achieve fast and easy patching between MTP backbone and LC patching. But for TAP cassette, except patching application, it is specially designed for network monitoring. Because there is a splitter in the TAP cassette, which can help achieve a complete copy of all traffic between two devices, for test and access purposes (click here to learn more about TAP cassette).


Between these three kinds of cassettes, TAP cassette is the most expensive one as it has not only the patching function but also the monitoring function. HD cassette is a little more expensive than LGX, because of the compact design and premium adapters. But actually, as the market continues to mature, LGX cassette and HD cassette are offered in a close cost by some vendors, e.g. FS.COM.

Type Product Description Price
HD Cassette 1xMTP Male to 6xLC/UPC Duplex, 0.35dB IL, Polarity A,12 Fibers 10G OM3 Laser Optimized MPO/MTP Cassette US$81.00
LGX Cassette 12 Fibers 10G OM3 LC Duplex 12 Strands MTP Male 0.35dB Standard LGX Cassette, Polarity Type A US$81.00
TAP LGX Cassette 2xMTP Female to 6xLC Duplex, 70/30 Split Ratio, 12 Fibers, OM3 10GBASE TAP LGX Cassette US$480.00

MTP LGX Cassette, HD Cassette and TAP Cassette are all widely used in today’s data center network to meet different demands. If your cabling system is not a high-densiy one, the LGX cassette can meet your demands in general. If you wanna to deploy it in the high density and ultra high density environment, you should choose the HD type. Of course, TAP is your preferred option when you require to monitor the data traffic.

Introduction to High-Density MTP/MPO Modular Patch Panel System

With the increasing demands on higher speed and more bandwidth, high density is becoming a main trend in today’s data centers. MPO/MTP pre-terminated solutions that are resulting in a fast interconnection of network components and a high utilization of fibers are launched to market to meet the demands on high-density cabling and connectivity. In today’s topic, I am going to introduce something about the high-density (HD) MTP/MPO modular patch panel system—an ideal patching solution in high-density cabling in data centers.

Main Products in HD MTP/MPO Modular Patch Panel System

High-Density Fiber Enclosures
High-density fiber enclosures, also called high-density fiber patch panels, HD enclosures or HD patch panels, are designed to accommodate up to 96 discrete connections within a 1RU panel space or 288 connections within a 4RU panel space. In general, the panel holds up to 4 or 5 cassette modules. Each cassette module support incoming fibers from either MPO/MTP trunk cables or directly terminated cable being connected to the cassette.


High-Density MPO/MTP Cassettes
The high-density (HD) MPO/MTP cassette is a type of MPO/MTP cassette exclusively designed for high-density applications. Though the HD MPO/MTP cassette is also used for secure transition between MTP and LC or SC discreet connectors, it is more compact than the traditional LGX MPO/MTP cassette, so that it can be more suitable for high-density applications, helping users saving more spaces.


Advantages of HD MTP/MPO Modular Patch Panel System

Compared to the previous patch panel solutions, the most obvious advantage of HD MTP/MPO modular patch panel system is to save more spaces.

What Should Be Considered When Choosing Fiber Patch Panels?

What Should Be Considered When Choosing Fiber Patch Panels?

Fiber patch panel, also called fiber enclosure, is used as a cost-effective method of fiber optic cable management and maintenance in today’s data center. With a fiber patch panel, installers can quickly do the cabling just by making changes to cables on the patch panel itself. What’s more, the patch panel also allows for easier cable management and identification of fiber cable routing. Nowadays, there are various of fiber patch panels on the market. Facing with a dazzling array of options, how to choose the right patch panel for your fiber network? This post introduces several points you should consider when choosing fiber patch panels.

Port Density

Port density seems to be a main concern when choosing a fiber patch panel, since the high density is becoming one of an important trends in data centers. At present, a normal 1RU fiber patch panel can support up to 48 ports while a high-density patch panel can support up to 96 ports. For MPO/MTP solution, there are ultra density panels which can support up to 144 ports in 1RU size. In addition, fiber enclosures with 2RU or 4RU size can help achieve higher port density, meeting any of your port requirement.


Rack Size

In general, rack size is used U or RU as its unit. This unit describes the height of equipment designed to mount in a rack. In data centers, the most commonly used rack size is 1RU. Additionally, 2RU and 4RU are also used for high-density applications. In this section, you should choose the proper size depending on your preferred working place of the panels.

Loaded or Unloaded?

When choosing a fiber patch panel, you will meet another parameters, such as loaded patch panel or unloaded patch panel. The loaded patch panel means that the patch panel is loaded with adapter panels, or cassettes sometimes. In data center applications, the most widely used adapter panels are equipped with LC and MTP adapters. Contrary to loaded fiber patch panel is the unloaded patch panel. For unloaded fiber patch panel, users should select cassettes and/or adapter panels according to their fiber connector type or use a splice tray for single- and mass-fusing. Unloaded fiber patch panel is more flexible than the loaded one, but may need an extra purchase for the accessories.
