What Is Structured Cabling And Why Use It?

The term structured cabling is like a buzzword in the cable management world. It plays an important role in dealing with the complicated and specific cabling. As a data transmission system, structured cabling supports data, multiple voices, video, and various management systems such as security access and energy system. Well, what is structured cabling? This article will address the importance of structured cabling and offer some tips on structured cabling installation.

What Is Structured Cabling?

What is structured cabling? Structured cabling is defined as building or campus telecommunications cabling infrastructure. Typically, it consists of a number of standardized smaller elements. In a structured cabling system, there is a structure created by a series of patch panels and trunks. It allows for a connection from hardware ports to a patch panel at the top of the rack. Then, that patch panel is connected to another patch panel through a trunk in the MDA. And the MDA (Main Distribution Area) is the main aspect of structured cabling. It provides a place for all the MAC’s (Moves, Adds, and Changes) to be made with short length patch cords.

Besides, a structured cabling system is specified by some standards like TIA/EIA-568. These standards provide guidelines for data center design, management and operation.

Six Subsystems of a Structured Cabling System

Generally, there are six key subsystems of a structured cabling system:

  • Entrance facility

Entrance facility includes the network demarcation point, cables, protection devices, connecting hardware, and other devices that connect with the on-premises cabling at the customer premises.

  •  Equipment room

The equipment room is a centralized location to house equipment and wiring consolidation points. It usually serves users inside the building or campus.

  • Telecommunications room or enclosure

Telecommunications room or enclosure should be an enclosed area. It is designed to house telecommunications equipment, cable terminations, cross-connects and distribution frames. Generally, each building has at least one telecommunications room or enclosure. And the size of the telecommunications room or enclosure is various based on the size of the service area.

  • Backbone cabling

The backbone cabling is also called vertical cabling or wring. It offers the interconnection between entrance facilities, telecommunication rooms, and equipment rooms. Commonly, this type of cabling is done from floor to floor, or even between buildings. And the equipment should be connected by cables of no more than 30 m. What’s more, the cables for backbone cabling can be fiber optic cable, coaxial cable, unshielded twisted-pair (UTP) cable, and shielded twisted-pair (STP) cable.

  • Horizontal cabling

The horizontal cabling refers to the cabling between telecommunications information outlet in the work area and the horizontal cross-connect in the telecommunications room (TR) or telecommunications enclosure (TE). It contains the telecommunications outlet, optional consolidation points, horizontal cable, mechanical terminations, patch cords or jumpers located in the TR or TE. This kind of wiring usually runs above the ceiling or below the floor. What’s more, both Ethernet cable and fiber optic cable are usually used for horizontal cabling.

  • Work Area

Work Area is a place where work-area components are used to connect end-user equipment to communication outlets. The work-area components are also called cable components, including patch cables, communication outlets, and station equipment.

SFP Compatibility Guide and How to Use a Compatible SFP Module?

With the development of fiber optic technology, a large amount of compatible SFP transceiver modules have been employed in the data center. However, there are still some doubts and worries about the compatibility and interoperability of SFP transceiver modules now. Therefore, here will have a thorough introduction to SFP compatibility and how to check it.

What Is SFP Compatibility ?

To understand the SFP compatibility, we’d better get to know the multi-source agreement (MSA) first. MSA is an agreement between many different transceiver manufacturers to make standardized products. Instead of being standardized by official standards, SFP is specified by MSA. It defines SFP modules including the size, connectors, and signaling to assure SFP modules are compatible with branded SFP devices. There are also MSA standards for other optic transceivers like SFP+, XFP, QSFP, etc. SFP transceivers meeting the SFP Compatibility requirement are usually compatible across a range of telecoms vendors’ hardware, therefore users can mix and match components from different vendors. In general, if an SFP can be connected to cables and switches correctly, and helps devices run successfully as you want, its SFP compatibility is qualified.

Figure 1: compatible SFP

Why Compatible SFP is Needed?

The major manufacturers like Cisco, HP, Juniper and so on, advertise that only the SFP modules with their brand can work with their devices. Of course, using official SFP module is indeed a good choice except for the high price. Whereas the cost is usually an important or even the first factor for consumers when buying some items. Utilizing the official SFP modules means that you have to pay much money than that of compatible SFP.

What’s more, some vendors don’t declare whether their SFP slots on the devices are compatible with standard SFP from other vendors or not. It will bring troubles to users when their device can not communicate with an SFP bought from other vendors.

The compatible SFP is also a standard product as long as it meets the MSA standard. It has the identical function with the official hardware, which is compatible with different telecoms vendors’ devices. So, using compatible SFP means that you can save a lot and don’t need to worry about your devices and SFPs coming from different vendors.

How to Use a Compatible SFP Module?

You may find that a compatible SFP transceiver can not work successfully in the branded switch. This is often not caused by the defective compatible SFP transceiver, but by improper behavior. The following are several guides for you to correctly use a compatible SFP module.

  • Check your transceiver module and device port

Some transceiver modules are easy to be mixed because of the similar appearances. For example, SFP and SFP+. SFP delivers 1Gbps of data and SFP+ supports the data rates up to 10 Gbps. Having the same size, an SFP module can fit seamlessly into the SFP+ port on the switch and vice versa. If you insert an SFP+ module into an SFP port, they will still work but the transmission speed will be limited at 1 Gbps. On the contrary, there will be no connection when an SFP module is inserted into an SFP+ port.

  • Ensure that the SFP modules have the identical wavelength at either end

It is known to us that the SFP module is used for data transmission. The transmission process is that the electrical signals from one side are converted into optical signals, then the lights are transmitted through the fiber and can be converted into electrical signals on the other end of the SFP module. To ensure this process, the SFP modules at either end should have an identical wavelength. So, you’d better look at the specifications of the SFP modules carefully.

  • Choose the correct fiber type

Choosing the correct fiber type is a major factor to make sure the SFP compatibility as well. So, you have to verify the fibers on both ends of the SFP modules, which should be the same type. The standardized colors on the outer jacket of fibers will help you identify them. What’s more, remember using the corresponding fiber cables.

  • Ensure both ports are compatible with the SFP module

It is important that the ports on your devices can accept the SFP modules you want to use. As mentioned above, some brands are not compatible with the SFP modules from other vendors. Even when using the compatible SFP modules, you’d better check the standards of ports firstly.

In-house coding and testing

What Is A Network Patch Panel?

The network patch panel is a passive mounted hardware assembly with multiple ports to connect and manage input and output cables that need to be connected to the networking hardware. It is usually attached to network racks, either above or below network switches or servers. Now there are many types of network patch panels designed for various applications. For example, there are Cat5e, Cat6, Cat6a, and Cat7 Ethernet patch panels for specific cable specifications. While according to the number of ports, 12-port, 24-port, and 48-port patch panels are also available. In addition, there are also unshielded and shielded patch panels, punch-down and feed-through patch panels.

Why Use A Network Patch Panel?

As mentioned above, a network patch panel servers as a static switchboard which connects numerous devices to a central server, switch or other critical hardware. If we don’t use it, we’ll have to run Ethernet cables from each device directly into the central hardware. Moreover, every time we want to reconfigure the network or cabling for more devices, it will be difficult for us to find out the right cables, unplug them and connect them to the new devices. Besides, network patch panels also benefit us a lot in the following aspects:

Easy for Cable Management and Identification

With network patch panels, all Ethernet cables can go into one central cabling location. This helps to keep the cabling system tidy and organized, avoiding cables from becoming tangled and messy. In addition, patch panels’ ports are often labeled, which allows us to better identify which cable comes from where.

Convenient for Reconfiguration and Troubleshooting

Since all cables are terminated on the network patch panel, the switch or server won’t be disturbed when small changes are made with the cabling. Furthermore, these changes can be made easily and quickly. As for troubleshooting, the clearly labeled ports make it easier to locate cables which need to be tested or replaced.

Reduced Risk of Outage

As we all know, there is a risk of damaging the surrounding cables when adding or removing a networking hardware. However, the usage of network patch panels can greatly reduce the risk of unplanned outages by making it easy to add and remove cables without touching the main hardware.

How to Buy A Network Patch Panel?

When buying a network patch panel in the market, you’ll find there are many options in terms of styles, cable types, number of ports, etc. It’s easy task to decide which cable type you use and how many ports you need for your cabling. However, you’d better be careful in choosing between network patch panels for home and patch panels for enterprise network or data center.

If you want to buy a network patch panel for home or small office, an unshielded Cat5e or Cat6 patch panel with 12 or 24 ports is often enough. And for most home users, they often choose the punch-down panel rather than a feed-through one for its cheaper price. If you buy a punch-down one, you’ll need to wire the patch panel by yourselves. Further more, wall-mounted network patch panels are also popular for home networks. For enterprise network or data center users, it’s better to use rack mounted shielded 48 port Cat6a or Cat7 patch panels. And the feed-through ones are also suggested.

When to Use A Gigabit Ethernet Switch for Home Network?

Before upgrading your home network to Gigabit Ethernet, you should know when it can offer a benefit and when it can’t. Not all network operations will benefit from Gigabit Ethernet. For example, Gigabit Ethernet won’t speed up things like Web browsing or the uploading and downloading of files from the Internet. This is because those activities are limited by the speed of your broadband connection. However, if there are multiple users accessing the same network device, Gigabit Ethernet will provide more total bandwidth to go around, which in turn result in less congestion and better overall performance. In addition, Gigabit Ethernet is also helpful when large file transfers are involved, like when you perform backups over the network to a server.

If you decide to deploy the Gigabit Ethernet, there is another thing to consider – buying a Gigabit Ethernet switch or Gigabit router. Generally, home Gigabit routers usually come with three or four Gigabit Ethernet ports built in. And most devices in a home network can support Wi-Fi. Therefore, most people don’t really need the switch. But a Gigabit Ethernet switch is essential when you don’t have enough Gigabit Ethernet ports for wired devices. Moreover, if you prefer to use wires for faster speed or plan to install Gigabit Ethernet ports in your home wall, a Gigabit Ethernet switch is also a better idea.

Home Network Gigabit Ethernet Switch FAQ

Q1: What shall I prepare for moving to Gigabit Ethernet?

First of all, you need to make sure your home devices can support Gigabit Ethernet. However, there is a good chance that your devices already support it because Gigabit Ethernet capability has been standard fare on desktops and other devices for years. Second, it is suggested to use Cat5e or Cat6 cabling for Gigabit Ethernet. So if you use Cat5 cables now, you’d better replace them. Though this may be troublesome, it is desirable in the long run. The last thing is to buy a Gigabit Ethernet switch best for your needs.

Q2: If I buy a Gigabit Ethernet switch, do I still need a router?

Sure you will need. Though the switch and router perform some similar functions, they each has its own function. The Gigabit Ethernet Switch can not connect to the Internet by itself. In other words, it needs a router to connect to the Internet. The mission of a Gigabit Ethernet Switch is to extend home network capacity.

Q3: How to buy a best Gigabit Ethernet switch?

A best Gigabit Ethernet switch here means it meets all your needs and the price is good. As mentioned above, the Gigabit Ethernet switch can be divided into managed and unmanaged, PoE and Non-PoE types with 5/8/16/24/48 ports. Unmanaged switches are plug-and-play, while the managed ones allow you to change network settings and other functions. Gigabit PoE switches are designed for home IP camera systems, or for situations where there is no power source for PoE enabled devices. As to the switch ports, you’d better choose one meets both your current and future growth needs. FS provides various Gigabit switches with competitive prices.
