Fiber Patch Panels for Ultra High Density Cabling

How to build a flexible and manageable cabling system in high density cabling environment is becoming an issue which has attracted increasing attention of many data centers. Cable management components like fiber patch panels have kept upgrading to meet the increasing needs for high density cabling. Proper using of fiber patch panels does not only provide well management for fiber patch cables in data center, but also protects the fiber patch cables and reduces the risks of faults cause by problems like bend loss, dusts and wrong connections. For ultra high density cabling like 40G and 100G connections, things would be more complex. Luckily, with clever design of fiber patch panels, customers won’t worry about fiber cable mess and faults caused by bad cable management.

Larger Fiber Count Means More Space Requirements

For 40G network, the backbone core signals are generally distributed into 4 strands of 10G signals in first. This process usually employs fanout MTP to LC fiber patch cables. For example, a 12-fiber MTP to 4 LC duplex fiber harness cable uses 8 fibers for 4 ways of duplex transmission. It means a fanout cable with a MTP connector and its 8 legs terminated with LC connector added in data center for a single duplex way of 40G transmission. In data center, a lot of 40G network should be built, which means the fiber cable count will be largely increased. Not to mention the 100G applications, which will increase at least 10 fibers for every 100G signal distribution.

Using Modular Design to Reduce the Space Requirements

To solve this problem, a series of fiber patch panels have been invented for 40G and 100G signal distribution applications. Here introduce two versions of ultra high density fiber patch panels which are designed for 40G and 100G applications separately: 1U 96-fiber MTP to LC breakout fiber patch panel and 2U 160-fiber MTP to LC breakout fiber patch panel. Both of them use the industry standard rack unit design, which can be installed on any standard rack.

The above picture shows the details of this 96-fiber breakout patch panel. On the back panel of this unit, there are 12 8-fiber MTP adapters which are separately linked 12 groups of LC duplex adapters on the front panel. Each of the 12 groups has 4 duplex LC adapters which can support 4 ways of 10G duplex transmission. Thus, the whole fiber patch panel can support up to 12*40G transmission in duplex ways. To decrease the error connections, each port has been clearly identified by numbers and groups.

A 160 fibers MTP to LC fiber patch panel uses a standard 2U rack design, which uses the same theory of the above mentions 96-fiber 40G fiber patch panel. The distribution of the 100G signals is generally achieved in 10*10G. There are 8 24-fiber MTP adapters on the back panel of this 100G fiber patch panel. Each of them connects a 24-fiber MTP adapter on the back panel to a group of 10 duplex LC adapters on the front panel. Thus, 8*100G duplex transmissions can be achieved with this 2U rack.


The above mentioned 1U 96-fibers MTP-LC fiber patch panel for 40G and 160-fiber MTP-LC fiber patch panel for 100G applications do not only decrease the space requirement for ultra high density cabling environment, but also decrease the faults caused by cable clutter, connection, disconnecting or bend loss by protecting the optical fiber in side a strong and reliable box.

Cabling With High Density Push-Pull Tab Patch Cords

It is inevitable to plug fiber patch cables from the patch panels, switches or cassettes in today’s data center cabling. However, this simple movement becomes harder and harder nowadays. Why? Both the data rate of every optical fiber and the fiber counts being used are increased to support high data rate up to 40/100G or more. Thus, the cabling density increased largely with the deployment of 40/100G Ethernet network. Finger access to every patch cable that is loaded on the patch panel, switches or cassettes becomes difficult. Especially for these patch cables in the middle of the space.

For fiber patch cords attached with connectors like LC, things become more complex. Because this type of connectors are usually locked in the port with a latch on the connector body. If you want to plug out a patch cord with LC connectors, you should firstly unlock the connector from the port by clicking the latch with is with small size (shown in the following picture). Usually an external tool is used to unplug the specific connector in a high density cabling. It seems a problem doesn’t matter much in the whole cabling. However, during practical cabling, network engineer could be headache about this annoying problem. To find an easy and elegant way to solve this finger access problem, a new type of patch cords was invented, which is designed for high density cabling and is known as push-pull tab patch cords.

What Is High Density Push-pull Tab Fiber Patch cable?

Compare with the traditional patch cords. This new type patch cord is attached with a connector with a push-pull tab, which can perfectly solve the fiber access problem in high density cabling. Except the additional tab for pushing and pull, these connectors don’t change much from the traditional ones that attached to patch cords. But this little change makes a great difference. The following is offering you the details about this novel product.

High density push-pull tab fiber patch cords are usually attached with LC or MPO connectors, as these two types of connector are currently the most popular in high density cabling like 40G, 100G, 120G or more. The following pictures shows the details of these two types of connectors with push-pull tab.

The one in the left of the following picture is an LC connector attached on push-pull tab patch cable. It’s of standard LC size. When the tab is pulled the LC connector would be unlocked from the port easily, cause the tab is linked to the latch of the LC connector. Once the LC connector is unlocked, the patch cords would be smoothly plugged out from the port and other patch cords around it by pulling the tab slightly. As for MPO connector with push-pull tab shown in the following picture on the right side. Finger access becomes easier. The tab can greatly simplify the use of MPO connectivity when manual access to the release slider and rear portion of the connector is restricted. In this way, easy insertion and extraction of MPO patch cords can be achieved.
