Product

The product is high stability output EDFA. The stability Pump optical maser and unique ATC (automatic temperature control) and APC (automatic power control) circuit are employed in it as the key component to ensure the high stability and reliability of output power;The unique optical circuit design ensures the excellent optical character. The high stability and high precision MPU system are employed to ensure the control adjustment and display is intelligent and easy.

This product is spectrum flat EDFA for DWDM system. The stability Pump laser and unique ATC (automatic temperature control) and APC (automatic power control) circuit are employed in it as the key component to ensure the high stability and reliability of output power, The unique optical circuit design ensures the excellent optical character. The high stability and high precision MPU system are employed to ensure the control adjustment and display are intelligent and easy. 

Professional design GFF (gain flattening filter) with excellent optical path design make flatness and noise reach the best optimization. It can provide 40~80 channels, and above 35nm flatness.

The optical circuit is designed especially for digital optical fiber communication system including, (1) lower noise figure, (2)high output booster and high sensitivity Pre-Amplifier improve the system loss budget, (3)Broad input power range and output power adjustable make it use easily. .

The design of dual Power Mixed and hot swap make it has longer MTBF. Also, the power system can be backup.

Employ the intelligent temperature control system,the fan is on when the module temperature over 45℃, meanwhile it will stop as the temperature is under 40℃, which makes sure the thermal stability and fan’s long life-time, meanwhile, the professional air flow design can also ensure the best temperature stability.

Intelligent network management system. Perfectly network interface: SNMP,WEB, CLI, TELNET  network interface,and the open mib ensure the connectivity with all other network management system.
