SDH Optical Terminator

SPDH Optical Terminator


In long-distance optical fiber transmission, the influence of optical cable on signal transmission is very small. The transmission quality of optical fiber transmission system mainly depends on the quality of optical terminal, because optical terminal is responsible for photoelectric conversion, optical emission and optical reception, and its advantages and disadvantages directly affect the whole system.

Overview and Application of SDH Optical Terminal Machine

Next, we will introduce the overview and application of SDH optical terminal in detail.

SDH optical terminal has a large capacity, usually 4E1 to 252E1. SDH is an integrated information transmission network that integrates multiplexing, line transmission and switching functions and operates by a unified network management system. It is a synchronous optical network (SONET) proposed by Bell Communications Technology Research Institute in the United States.

In 1988, the International Telegraph and Telephone Advisory Committee (CCITT) (now ITU-T) accepted the concept of SONET and renamed SDH, making it a general technical system applicable not only to optical fibers but also to microwave and satellite transmission. It can realize many functions, such as effective network management, real-time business monitoring, dynamic network maintenance, interworking between different manufacturers and equipment, etc. It can greatly improve the utilization rate of network resources, reduce the cost of management and maintenance, and realize flexible, reliable and efficient network operation and maintenance. Therefore, it is the transmission technology side in the field of information in the world today. Hot spots of development and application.

Following Huawei and ZTE, our company independently develops, produces and sells optical communication network products. Based on FTTH and FTTD, all-optical access network equipment and terminal products, our company develops and produces optical communication network products. Over the years, we have been focusing on the transmission and access of Ethernet products. Our sales network covers more than 30 provinces and cities in China, Southeast Asia, Europe and the United States.
