Product Introduction

WDM EDFA 16 Port 23dBm

I. Overview

SPA-XX Series 1550nm high power fiber amplifier adopts two-stage amplification, the first stage adopts low-noise EDFA, the second stage adopts high-power EYDFA, the total output optical power can reach 37dBm. It can replace several or dozens of EDFA, which can greatly reduce the cost of network building and maintenance and reduce the space of head-end. Each output port is built in with CWDM to multiplex CATV signal and OLT PON Data flow. The device will play an increasingly important role in the process of continuous extension and expansion of optical fiber network. It provides a high stability but low cost solution for the triple-play and large area coverage of FTTH.

II. Features

Each output port is built in with CWDM.
Compatible with any FTTx PON：EPON、GPON、10GPON
It adopts the top brand pump laser and double cladding active fiber
Output adjustable, adjustment range : 0~-4dBm.
RF test in the front panel(optional).
Built- in dual power supply, automatically switched and hot plug supported.
Standard RJ45 interface is provided, supporting SNMP and WEB remote network management.
It has the function of automatic protection of low input or no input. When the input optical power is lower than the set value, the laser will automatically shut down to protect the operating safety of the device.
