Product Description

Softel 1550nm FTTx PON Optical Erbium-Doped Fiber Amplifier (EDFA) with Output Optical Power of 18dBm for CATV Network

·Characteristic
1. Adopt several international patents pre-distortion dealing technology to guarantee the fine non-linear index, good CSO,CTB and C/N.

Adopt famous brand 1550 nm DFB laser instrument guarantee low noise, high power and high dependability.

2. Can initiate the mode SBS function, offer more elastic disposition.

3. Adopt Automatic Gain Control design, make different RF input level keep about equal output performance still, Simplify installing and operation sequence.

4. The built-in microprocessor offers fine control performance and state to show that is controlled.

5. RS485 controls the interface to control by carrying on the remote state.

6. 191U high-standard framework type installation.
