    Description

    Overview

    FTTH EDFA High Power is for CATV and satellite direct TV, integration of Analog TV, Digital TV (DBS-C, DBS-T) and Satellite TV, supports Telnet and SNMP network management. The FTTH EDFA High Power is a C-Band Er-Yb co-doped double cladding optical fibre amplifier with a high output power. The high-reliability multimode PUMP laser and the double-cladding optical fibre are the product’s main features. The high stability and dependability output power is ensured by a proprietary ATC (Automatic Temperature Control) and APC (Automatic Power Control) circuit, while the unique optical circuit design assures exceptional optical performance. The MPU system’s excellent stability and precision enable intelligent and simple operation, adjustment, and display.

    These FTTH EDFA High Power are commonly used in CATV transmission systems and high-power FTTH distribution systems. It can be used for CATV analog/digital signal transmission, or it can be linked with a PON system to create a triple network. (WDM with three wavelengths is an option.)
