GYFTZY (non-metal flame-retardant fiber optic cable) is strictly not a special fiber optic cable for our power fiber optic cable. But when our power optical cable line enters the substation, the substation has strong current occasions, and the requirements for lightning protection and flame retardancy are very high. Therefore, it is necessary to use non-metallic materials and good flame retardant optical cables. GYFTZY non-metal flame-retardant optical cable is generally used.

In the FTTH network, cable management is a real task. In order to transmit signals to multiple terminations, large amount of optical pigtails are used in the cabling system. A solution must be found to solve the problem of cable routing. Luckily, the advent of fiber termination box has efficiently h

During the actual operation of fiber cables, fiber optic splicing is often needed to achieve the connection between optic fibers. To be specific, fiber optic splicing is a process to combine the ends of optic fibers together. And only one end of each individual fiber is required. There are mainly two types splicing methods: the mechanical splicing and the fusion splicing. The article will introduce these two splicing methods and their particular steps of splicing.

Fiber optic isolator is a passive component used for fiber optic communications. As a magneto-optic device, the purpose of optical isolator is to allow light to be transmitted in only one direction.

Multimode and single-mode optical fiber cables are two different cable types in optical networking. Using a larger core size, multimode fiber cable allows multiple light signals to be transmitted in a single fiber over short distances. Multimode fiber systems offer flexible, reliable and cost effective cabling solutions for local area networks (LANs), storage area networks (SANs), central offices and data centers. Unlike the complex classifications of single-mode fiber, multimode fiber is usually divided into four types of OM1, OM2, OM3, OM4. “OM” is abbreviated for optical multimode, and it is specified by the ISO/IEC 11801 international standard. Of course, these four types of multimode fiber have different specifications (as shown in the following table). The article will compare these four kinds of fibers from the side of core size, bandwidth, data rate, distance, color and optical source in details.
