The Need for Ultra Low Loss Fiber Patch Cables in Data Center

Fiber optic cables are now indispensable transmission media in data center. But during the transmission, attenuation of optical fibers becomes one of the top concerns since it greatly impacts the signal transmission, and what’s worse, it’s difficult to avoid, especially in the long distance transmission of high-speed backbone network. Under such a background, the introduction of ultra low loss fiber patch cables provides a new way to solve this problem. This post will reveal why ultra low loss fiber patch cable is superior and different types of ultra low loss fiber patch cables provided by FS.COM.

Why Ultra Low Loss Fiber Patch Cable is Advantageous?

Lower Attenuation—According to the loss of optical fiber, the optical fiber is divided into common fiber, low loss fiber and ultra low loss fiber. Among them, the attenuation of common optical fiber is about 0.20dB/km, and the attenuation of low loss fiber and ultra low loss fiber is lower than 0.185dB/km and 0.170dB/km respectively. Compared with common fiber, low loss fiber and ultra low loss fiber can respectively reduce cross section loss of 2dB and 3dB. For the future transmission rate of 400G, low loss optical fiber can reduce about 20% of regeneration stations, while ultra low loss optical fiber about 40%. The benefits and advantages of ultra low loss fiber cable are obvious and noticeable.

Network Redundancy—Compared with common fiber, the excellent characteristics of ultra low loss fiber provides network redundancy for expansion of network transition span and site, for upgrading to the faster bit rate and an increase of network components’ flexibility or extension of the distance between regenerators in order to achieve longer and wider regional network and satisfy the global increasing demand for bandwidth capacity.

Low Cost—In addition to aforementioned advantages, the use of ultra low loss fiber cable can greatly reduce cost. The reduction of a regeneration station means saving millions of dollars. With the forthcoming of 400G, compared to common fiber, low loss fiber can reduce 20% (about 0.3 billion dollars) of 400G regeneration station, while ultra low loss fiber cable about 40%.

Types of Ultra Low Loss Fiber Patch Cable

In order to offer better performance for our customers, FS.COM introduced two types of ultra low loss fiber optic patch cables.

Ultra Low Loss Single Mode Fiber Patch Cable

FS ultra low loss single mode fiber (SMF)features a typical insertion loss of 0.12dB. The cable is designed for signal transmission over the 1310nm and 1550nm wavelength. And it has Grade B connector which can ensure ultra low IL (insertion loss) and RL (return loss) and avoid the production of error code and worse signal. In addition, the material of the single mode fiber is G.657.A1 (Compatible with G.652.D)which allows the cable to be bent more severely than standard patch cables.

Ultra Low Loss Multimode Fiber Patch Cable

Multimode fiber (MMF) is a cost-effective solution for short-reach optical interconnects of up to a few hundred meters. The low insertion loss MMF from FS.COM ensures ultra low maximum loss of 0.15dB at the wavelengths of 850nm or 1300nm. The common types of low insertion loss MMF include OM2, OM3 and OM4. With special material design, it also offers excellent hydrogen aging characteristics, which guarantee stability of fiber application. All in all, this ultra low insertion loss MMF cable fully meets the demands for transmitting signals with high speed and high capacity.
