As data center ages, its speeds have maintained continuous growth over the years, such as 10Mb/s, 100Mb/s, 1Gb/s, 10Gb/s. In this big data age, more and more enterprises and organizations have stepped forward with the ongoing transition from the previous 10GbE networks to 40GbE networks, or beyond. And the big increase in network servers for data storage has led to the growing demand for high-density cabling systems. As such, push-pull patch cords, a new type of fiber optic patch cord, are designed for high density cabling, which allows for improved accessibility and reduced installation costs, an ideal solution for the high density patching environments. Maybe you have few ideas about these push-pull patch cords, and just hear the name. Don’t worry. This article is gonna give the detailed description about them.

AS we all known that it’s necessary to plug fiber patch cables from the patch panels, switches or cassettes in the data center cabling system. However, this plugging becomes increasingly harder especially in those 40/100GbE networks, since the fiber counts are increased to support such high data rates. Finger access to every patch cable becomes difficult.

For fiber patch cords with LC connectors, it’s a little tricky because this connector type is usually locked in the port with a latch on the connector body. In theory, 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. Usually an additional tool is used to unplug the specific connector in a high density cabling. But in practice, network engineer could be upset about this annoying problem during cabling. To find an easy way to solve this finger access problem, patch cord with integrated push-pull tab was invented for high density cabling, known as push-pull tab patch cord (image below). It has been proven that push-pull tab can increase the cabling density by 30% to 50%, which can accommodate the future high density cabling requirements.

As mentioned above, push-pull patch cord is a new fiber patch cord type with a flexible "push/pull-tab” permitting the connector to be disengaged easily from densely loaded panels without the need for special tools. More specifically, its unique push-pull tab allows for easy finger access and a secure holding fixture for any patching or handling process. Actually, judging from construction, push-pull patch cord enjoys the same components and internal-structure as its former fiber patch cable, except for a tab attached to the connector designed for pushing or pulling the whole connector. With these special design, technicians and cabling installers can accomplish the installing and removing processes with only one hand, free from the use of additional tools.

When it comes to push-pull patch cord classification, there are mainly two versions: push-pull tab LC patch cord and push-pull tab MPO patch cord (figure shown below). LC-HD TAB and MPO-HD TAB are designed for the switchable & movable LC connector and MPO connector, respectively, allowing easy and simple management of high density fiber patch cords.

Why users choose push-pull patch cords for data center cabling? The above mentioned finger access is definitely not the only reason. The following lists other advantages.

• Easier Operation

For fiber patch cords, the duplex latch of which often sits underneath the base of the connector above, inserting and disconnecting them can be a little difficult. With push-pull patch cords, whose latch is extended out to the space in front of the connector, pull and disengage the patch cord with push-pull tab is easier. In a word, the use of push-pull patch cord increases operational accessibility.

• Increased Flexibility & Adjustability

Push-pull patch cords are designed in various specifications, able to connect different generation of devices from 10Gb/s to 40Gbp/s or beyond. They offer safe and easy pushing and pulling of the specific connector without affecting the other connectors around it.

• Less Space & Lower Cost

Besides, this high-density cabling solution provides easy installation of fiber patch cords, helping to save time and leading to a low initial investment cost accordingly. A high return on investment.

Push-pull patch cords ensures more operational accessibility, less installation or removing time and expenses, providing exceptional finger access even in the highest density environments. Fiberstore supplies many high-quality and low-cost push-pull patch cables with LC-HD TAB and MPO-HD TAB. These push-pull tab LC patch cables and push-pull tab MPO patch cables are all quality-assured to allow for smooth and high-density connections between network equipment in the rooms.
