High Output Power 1550nm Erbium-doped Optical Fiber Amplifer EDFAUS$ 710 - 1,200MOQ: 1 Set
Features:
1) Use international famous brand of low noise pump lasers, with feature of low distortion, wide band and high output power.
2) Adopt imported high quality erbium-doped fiber which is highly-efficient in the energy transformation.
3) With plug-draw module. It could be changed as required to get optical amplifier with different output power. Besides, it supports interior optical divider to output in many ways. Meanwhile, it is convenient to replace the faulty modules.
4) With two backup power supply which is in the form of plug-draw.Two groups power supply carry 50% consumption of power.
5)Radiating in two ways: radiator and fans. So the efficiency is improved by ten times.
6) With inside perfect micro-processing auto-supervise circuit. It could monitor precisely various status of the laser and also of optical input and output power to ensure the stability of optical output power, and to prolong the life span of the laser.
7)With RS232 computer interface, RS485 standard interface and RJ45 Ethernet interface (for option); With LCD display embedded in the front panel which could display working parameter.
8) Ethernet interface provides advanced web management function. It is based on SNMP agreement and meets international criterion and Chinese criterion of HFC web management system GB/T20030-2005, it could also meet other companys criterion.
