Data center is a place of thousands fiber links. The selection of fiber patch cables will directly affect the network performance. More and more data centers choose to select fiber patch cable of high performance. Generally, insertion loss and return loss of connectors terminated on patch cable and light lack of optical fiber used for fiber patch cable are three most basic factors for fiber patch cable selection. To satisfy the increasing demands for higher density and easier management in data center, the optimization of fiber patch cable has never stopped. The following introduces many popular LC-LC fiber patch cables which represent the trends of fiber patch cable that data center is certainly asking for.
Low Insertion Loss and Bend Loss LC-LC Patch Cable
When a length of fiber patch cable is connected in network, optical light loss occurs at the optical fiber and the connectors terminated on it. There are different optical light losses, among which insertion loss at the connectors and bend loss in fiber optic cables are the two most commonly light losses that technicians are trying to overcome. Manufactures provides LC-LC fiber patch cables which can minimize these losses to the most.
Insertion loss refers to the fiber optic light loss caused when a fiber optic component insert into another one to form the fiber optic link. To provide low insertion loss patch cable, LC connectors terminated on the patch cable has been optimized. Standard LC-LC patch cable usually has an insertion loss less than 0.3 dB. However, for upgraded LC-LC patch cable, the insertion loss is normally lower than 0.2 dB. To decrease the bend loss, a type of bend insensitive fiber(BIF) has been used in fiber patch cable. With optimized LC connectors and bend insensitive fiber, LC-LC fiber patch cable could provide lower light loss during network transmission.
High Density LC-LC Patch Cable
LC connector was invented for higher cabling density. standard duplex LC-LC fiber patch cable can provide much higher cabling density than various other duplex fiber patch cables. To further increase cabling density in data center, the connectors and cable diameter of LC-LC patch cable are becoming smaller. Uniboot LC-LC patch cable is normally a typical example. This sort of fiber patch cable designed the two fibers of the duplex patch cable into a single cable. In adding both connectors terminated at each end of the duplex patch cable share the same boot. With less using cable counts, uniboot patch cable can offer higher cabling density and better cooling environment in data center.
Polarity Switchable LC-LC Patch Cable
The development of patch cable won’t stop at low loss and high density. Making fiber patch cable easier-to-use is also important. Polarity of fiber patch cable matters a lot during installation of fiber patch cable, especially for duplex fiber patch cable and MTP patch cable . It is common to change the polarity of a duplex patch cable during deployment. Technicians might need tools to improve the polarity of patch cable. However, a polarity switchable LC-LC patch cable can make things much easier. Without any tools you can polarity reversal could be really easy.2
