Using Ultra Low Loss Fiber Cable for Data Center

Posted on by FS.COM

As the most commonly used components in optical transmission system, the performance of fiber optic cable and connector is critical to signals transmission. Sub-standard patch cords and fiber connectors will affect the reliability of the network and are often the most common source of failure in an optical network. In fact, the risk of network downtime due to unreliable cabling can be avoided effectively. This post intends to introduce the basis of insertion loss and how to achieve quality optical transmission.

Understanding Optical Loss in Fiber Networks

Good fiber optic performance relies on connectors that are manufactured properly. Insertion loss is one of the key factors that will affect the performance of optical fiber networks. It refers to the reduction in optical power across the link caused by applying a connector or splice. Here we mainly talk about the loss caused by a fiber optic connector.

Fiber optic connectors are widely applied in all types of network, at the input and output ports of the transmission systems and are also used to connect test equipment and instrumentation. The main effects of the introduction of a connector in an optical line are an attenuation on the transmitted signal and a reflection of a part of the signal.

Random mating, refers to random mating between randomly selected plugs from production, is a professional method to test the insertion loss and offer a reference and guarantee for customers to choose quality fiber jumper cables.The following table shows the four grades of fiber optic connector which is based on this testing method.

*IEC 61753-1 specifies four Random Mating IL performance grades, of which grade A has not yet to be defined.

In the market, the IL (insertion loss) value that many vendors adopt just suits some controlled environments, but not suits some the field performance. But the result of this testing is random, which is more convincing. From the table, we can see there are four different grades of optical connectors. Take Grade B as an example, it means in all selected samples, the max insertion loss value of more than 97% samples is less or equal to 0.25dB, and the mean value needs to be less than or equal to 0.12dB.

FS.COM Ultra Low Loss Fiber Patch Cable Solution

The use of fiber optic patch cable will affect the data center performance directly. Therefore, high-quality fiber optic patch cables are what network managers need mostly. In order to offer better performance for our customers, FS.COM newly announced two types of ultra low loss fiber optic cables.

Ultra Low Loss Single Mode Fiber Patch Cable

As it name shows, this single mode fiber cable (SMF) cable features a typical insertion loss of 0.12dB, which has a great improvement than standard fiber patch cords of 0.3dB. 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 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 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 is made of superior ceramic ferrules which meet the requirements of IEC 61754 and YD/T, ensuring 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. In all, this ultra low insertion loss MMF cable fully meets the demands for transmitting signals with high speed and high capacity.
