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.

Nowadays, the requirements for higher Internet access speed keep growing in different applications such as video conference, 3D and cable TV, which result in popularity of FTTH (fiber-to-the-home) deployments. Passive Optical Networks (PON), as the leading technology used in FTTH applications, are also widely used. PON transceivers are one of the important components in PON systems. This post intends to describe some basic knowledge of PON transceivers.

In FTTH network design, optical splitters play an important role in the passive optical network (PON) by allowing a single PON interface to be shared among many subscribers. Optical splitters are installed in each optical network between the PON OLT (Optical Line Terminal ) and the ONTs (Optical Network Terminals) that the OLT serves. To design and deploy an FTTH network successfully, the FTTH splitting level and ratio are a problem that should be solved.

The emerging interest in fiber to the home (FTTH) networks has swept over the whole telecommunication industry. With continuing demand for more bandwidth, telecom service providers have begun to deploy optical fiber deeper into the network and closer to the subscriber residence. The drop cable connection serves as a key component in FTTH networks. Choosing the right drop cable interconnect solution will directly affect network reliability, operational flexibility and the economics of FTTH deployment. This article will highlight the various technical considerations which should be made when selecting optical drop cable for FTTH networks.

Single mode cable and multimode cableTransmission of single-mode fiber optic cableWhat single-mode fiber optic cables actually use for transmission is an intermediate fiber core, called an optical fiber. That is, single-mode optical cable is composed of optical fiber + outer sheath + intermediate me
