Optical fiber is the foundation of current network construction. There is no doubt that the service life of optical fiber is more than 20 years, and it is difficult to change after the laying and construction are in place. Therefore, the selection of carrier-grade multi-mode optical fiber jumper needs to consider all network requirements during its lifetime. Ultra-low loss carrier-grade multi-mode fiber optic patch cords are sought after by the market. Let’s take a look at the application and transmission distance of ultra-low loss fiber models

Application and transmission distance of ultra-low loss fiber models

According to optical fiber loss, the industry roughly divides optical fibers into three types: ordinary optical fibers, low-loss optical fibers, and ultra-low-loss optical fibers. Among them, the attenuation of ordinary fiber is about 0.20dB/km, and the attenuation of low-loss fiber and ultra-low-loss fiber is less than 0.185dB/km and 0.170dB/km respectively. Compared with ordinary fibers, low-loss and ultra-low-loss fibers can reduce span loss by 2dB and 3dB respectively. Even if the number of spans remains the same, it can increase the distance of each span by 17%, and the total transmission distance has also increased by 17%.

For high-speed transmission networks, at a transmission rate of 100G, ordinary optical fiber, low-loss optical fiber, and ultra-low-loss optical fiber can transmit more than 1000 kilometers. Except for some long sections, the existing ordinary optical fiber can handle it; and for 400G transmission Speed, low-loss fiber can reduce the number of stations by about 20%, and ultra-low-loss fiber can reduce the number of stations by about 40%, with obvious benefits.

Compared with ordinary optical fiber, the excellent characteristics of ultra-low loss optical fiber can provide network margin, which can be used to extend the network transition span, amplify the site, upgrade to a faster bit rate, increase the flexibility of network components or extender In this way, a longer and wider area network can be realized to meet the increasing demand for bandwidth capacity of countries around the world.

The low-loss characteristics of ultra-low-loss carrier-grade multi-mode fiber optic jumpers are very suitable for long-distance, large-capacity, and high-speed network transmission applications, and a series of record-setting application results have been produced. In addition, ultra-low loss optical fiber is not only widely used by operators, but also takes into account low attenuation characteristics.

400G has come strongly, at this time the application of ultra-low loss fiber models will become more and more attractive. With the continuous completion of the industry chain, ultra-low loss optical fiber will usher in the era of large-scale commercial use.
