TOFA-422W - 4 Port 1550nm High Power PON EYDFA

Description

The total output optical power can reach 37dBm, optical power of 1550nm per output port is not less than 19dBm/22dBm (optical power level selectable),
replacing multiple EDFA units. Each output port has built in CWDM to multiplex CATV signal and OLT PON Data flow, ideal for FTTH applications. The TOFA-
422W offers excellent performance and reliability and supports network management and power redundancy
FEATURES
TOFA-422W adopts a high-quality pump laser and double cladding active fibre
Each output port has built in CWDM
Compatible with any FTTx PON: EPON, GPON, 10GPON
Perfect APC, ACC and ATC optical circuit design ensures low noise, high output and high reliability of the device in the whole operating band (1545 ~ 1565nm)
Automatic protection of low input or no input. When the optical power at input is lower than the set value, the laser will automatically shut down to protect the operating safety of the device
Output adjustable, adjustment range from 0~-4dBm
CATV/PON dual fibre inputs
Fast switching time of optical switch with low loss (automatic and manual)
Built-in dual power supply, automatically switched and hot plug supported
The operating parameters of the TOFA-422W are controlled by a microprocessor, and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management. Once the operating parameters of the laser deviate from the range set in the software by the user, the system will issue an alarm
Standard RJ45 interface is provided, supporting SNMP and WEB remote network management
