Product Overview
1.OPA-1550W-1GAG 1550nm high power optical amplifier adopts two-stage amplification. The first stage adopts low-noise EDFA; the second stage adopts high-power EYDFA. And the total output optical power can reach 41dBm. 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 GPON or XGSPON 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 large area coverage of FTTH.
2.Optional dual fiber inputs, in fact, built-in with a set of complete optical switch system, which can be used as the backup of A and B optical path. When the main optical line fails or lower than the threshold value, the device will automatically switch to the standby optical line to ensure the continuous operating of the device. The product is mainly used in optical fiber ring network or redundant backup network, It is featured in short switching time (<8ms), low loss (<0.8dbm), and can be forced manually switched.
3.The core component adopts the top brand pump laser and double cladding active fiber. The optimized optical circuit design and manufacturing process ensure the best optical performance. The perfect electronic controlled APC (automatic power control), ACC (automatic current control) and ATC (automatic temperature control) are adopted to ensure high stability and reliability of output power, as well as excellent optical performance.
4.MPU (microprocessor) with high stability and precision is adopted in the system. The optimized thermal structure design, good ventilation and heat dissipation design ensure the long life and high reliability of the device. Based on the powerful network management function of TCP / IP protocol, network monitoring and head-end management can be carried out for the status of multiple node equipment through RJ45 network management interface, supporting multiple power supply redundancy configurations, which improved the practicability and reliability of the device.
5.In consideration of the request of inserting and plugging patch cord in the working stateof the device, a maintenance function with a rapid drop of 6dB is added to protect the fiber core.
The output power is reduced by 6dB instead of turning off the power supply. It will not cause a large area of out of service, but only a short-time signal decline.
The function is featured in:
A: After 6dBm reduced, the output power per port is ≤18dBm; the value makes it available to pug in and out patch cord without hurting or burning the fiber core of patch cord.
B: It can return to original working status quickly after maintenance.

Features
1.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.
2.Compatible with any FTTx PON: EPON, GPON, XGPON.
3.Output adjustable, adjustment range 0~-4dBm.
4.RF test in the front panel (Optional).
5.Build-in optical switch system is short and the loss is small. It has the functions of automatic switching and forced manual switching (Optional).
6.Built- in dual power supply, automatically switched and hot plug supported.
7.Standard RJ45 interface is provided, supporting SNMP and WEB remote network management.
