Since the requirements for bandwidth keep growing all the time, more and more fiber optic cables are being installed in telecommunication area within a given space. What characteristics do you expect most for the fiber patch cables in your high density cabling? In order to achieve the desirable performance of fiber patch cords, the most unwanted problems of them have to be minimized. And parameters corresponding to these problems are what usually cared most when selecting a good fiber patch cable, which include the insertion loss (IL) and light loss of the cable. And another issue is the space they take up. Some technologies are developed to make better fiber patch cables for higher density data center applications, and this post will introduce some extraordinary ones of them.
During fiber installation and maintenance, it is inevitable to bend the fiber patch cable, especially in a narrow space. But fiber bending is very bad for the signal transmission, because some light in the outer part of the core will be lost when stressed by bending. Thanks that bend insensitive (BI) fibers are created to minimize the bending loss. An annular ring of lower index of refraction material with very carefully designed geometry is added around the core, so as to maximally reflect the weakly guided light back into the core instead of being coupled into the cladding and lost.
There is BI single-mode fiber (BISMF) and BI multimode fiber (BIMMF) in the market. The minimum bend radius of the fiber from different vendors varies, and the insertion loss of BIF patch cables is unequal. And for BIMMF, the compatibility with conventional multimode fiber is also a question that should be considered.
FS.COM offers OS2, OM1, OM2, OM3 and OM4 BIF patch cables with ultra low IL and bend radius, ensuring high performance of data transmission. Our BISMF patch cables are made of G.657.A1 standard fiber from Corning and connectors with IL less than 0.12 dB, owning a minimum bend radius of 10.0 mm. Insertion loss of these BISMF patch cable connectors is rated as grade B in Random Mating, which is rather high-performance specified by IEC 61753-1. And the BIMMF patch cables have an IL less than 0.15 dB, with a minimum bend radius of 7.5 mm. Both LC and SC duplex BIF patch cables are supplied at FS.COM. One thing should be noted is that FS.COM BIMMF cables can be spliced or connected to conventional multimode cables without any problem.
LC fiber patch cable is the most popularly used type in data center installation because of its smaller connector size. As for LC uniboot patch cable with single-cable and single-boot design, it is even more compact than traditional LC duplex patch cable with two-cables design. LC uniboot cable has two fibers firmly enclosed in a single cable, and only one boot is terminated at the back of the duplex LC connector. So compared with standard LC duplex patch cable, it reduces the cable count to 50% and saves much space. Due to its compact design, it is also easier to install patch cables in higher density areas. The typical insertion loss for standard LC duplex cable is 0.3 dB, but by using some advanced methods it can be reduced to 0.2 dB. We provide high quality LC uniboot cables with lower typical IL.
Another type of LC uniboot cable for convenient polarity switching is also developed. This polarity switchable uniboot cable has a novel connector design, which enables much easier polarity reversal without additional tools or fiber cable re-terminating. Compared with traditional LC duplex patch cable, this new LC uniboot cable does save much time and money in polarity changing. FS.COM high density switchable LC uniboot cable has a maximum 0.12 dB IL. It is also high-standard in every aspect. Only three steps are needed to reverse the polarity of this patch cable.
BIF patch cables and various LC uniboot patch cables are great creations for high density cabling. All those patch cables with ultra low loss and user-friendly design are even more favorable in real installation. FS.COM has been devoted to provide high quality fiber optic cables to make your system better connected.
