High Density Is the Trend
High Density seems to be the trend of this century. Every industry chases it. It is also true to optical communication industry. Especially when more and more data centers are upgrading to 40G and beyond, the trend and importance of high density become more significantly. Switches today can provide more ports with higher data rate due to the shrinking of port size and advancement of technology. To fit these ports and achieve photoelectric conversion with higher data rate, fiber optic transceiver also shrinks largely in both size and interfaces. A typical example is the using of 40GBASE QSFP+ transceiver which can support transmission data rate of 40G with a small size and MPO or LC interfaces. However, new problems come out.
It is inevitable that fiber optic connectors need to be plugged in switch or pulled out from switches during cabling and daily maintenance. But for high density cabling, finger access to each patch cable and connector becomes harder. It is almost impossible to unplug these connectors on the high density patch panel, especially when they are right in the middle of the space. For patch cords with connectors like LC that are locked on the interface, it would be more difficult, because you have to firstly unlock the connector from the port before pull it out from the port (Shown in the following picture). Most of the time a special tool is used. High density cabling and maintenance become more difficult and time-consuming. To solve this problem, this post offers you a simple and easy solution for high density cable management, which will definitely make you exciting.
Here introduces a new patch cord with a special “pull” tab design that can help to solve the problems of finger access in high density cabling. There is not much difference between this one and traditional patch cords. But a little change can make great difference. The following will give you an understanding of what this high density push-pull tab patch cable is.
A push-pull tab patch cable has the same components and internal-structure as the traditional patch cords, except a tab attached to the connector used for pushing or pulling the whole connector. This small push-pull tab looks simple but it is functional for high density cabling in 40/100G migration. High density cabling for 40G/100G and beyond usually employs MPO and LC connectors. The following suggested push-pull tab patch cables are attached with MPO or LC connectors.
LC Connector Attached to Push-pull Tab Patch Cable
The on the left of the picture below shows the structure of a LC connector attached to push-pull tab patch cable. The main body of the LC connector is of the standard size. The push-pull tab looks simple but it is linked to the latch of the LC connector. When the tab is pulled the latch will be unlocked easily and the LC connector can be pulled out from the patch panel without difficulty. It has been proved that LC push-pull tab patch cords can increase cabling density more than 50%.
MPO Connector Attached to Push-pull Tab Patch Cable
On the right of the picture above is a MPO connector attached with push-pull tab. 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.
Cabling with push-pull patch cords all you need is one hand and no external tools are required. The push-pull tab can offer exceptional finger access even in the highest density environments. The push-pull patch cord can be inserted and removed by pulling or pushing the connector. These cables are available with OM3, OM4 and single-mode optical cable types.
Get More From Push-pull Tab Patch Cable
The benefits of push-pull tab patch cable are not limited to the easy access of the fiber optic connector. You can get more from this type of patch cords:
- Higher flexibility and adjustability: push-pull patch cords are available in various specifications which can connect different generation of devices from 10Gb/s to 120Gbp/s or more.
- Space-saving: with push-pull patch cords, spare space for cabling is reduced which can increase the density of cabling further more.
- Reliability: push-pull patch cords provide safe and easy push and pull of the specific connector without affecting the other connectors around it.
- Economical: high density and ease of installation provide a low initial investment cost. The above mentioned benefits provide a high return on investment.
We started with 1G switches. Those switches became 10G. Recently we’ve seen the trend of 40G. In the future, those switches will become 100G and even 120G. It has been proved that push-pull tab patch cords can support high durability and flexibility which fit the connection between devices of different data rate. If you are looking for the connection solution for these devices, Fiberstore offers you the best. The following chart shows you four most common applications of push-pull tab patch cords.
