1550nm Single/Multi Output CATV High Power EDFA
1. Application
Single-mode fiber 1550 amplification network
FTTH network
CATV network
2. Performance Characteristics
SPA-XX is a low noise high-performance Er Yb co-doped fiber amplifier. Each output built-in CWDM (1310/1490/1550) wavelength division multiplexer. Conveniently multiplex the data stream of OLT and ONU to the fiber amplifier output by 1310nm and 1490nm optical connector. Thus reduced the equipment quantity, improved the system indexes and reliability. It is the ideal equipment for FTTx network, provides a flexible and low cost solution for the integration of three networks and the FTTH.
Adopts Er Yb Codoped double-clad fiber technology;
Output ports: 4-16 optional;
Optical output power: total output up to 5W;
Low noise figure: <5dB when input is 0dBm;
Perfect network management interface, in line with standard SNMP network management;
Intelligent temperature control system make the power consumption lower;
