Description
Overview
GAOTek high power optical amplifier adopts two-stage amplification. The first stage adopts low-noise EDFA, the second stage adopts high-power EYDFA. 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. It will play an increasingly important role in the process of continuous extension and expansion of optical fiber networks.
Features
- Adopts top brand pump laser, double cladding fiber
- Each output port has built-in CWDM
- Compatible with all FTTx PON, EPON, GPON, 10 GPON
- APC, ACC, ATC design ensures low noise
- Automatic protection for low or no input
- Adjustable output, range: 0 dBm to -4 dBm
- Optional RF test in front panel
- Optical switch has short switching time
- Dual power supply, automatic switch, hot plug
- Microprocessor controls machine, LCD displays status
- Provides standard RJ-45 interface, supports remote management
