1U Single Fiber Bi-Directional Optical Fiber Amplifier EDFA

Product Details

Product Introduction

The product is a high stability output power EDFA. The stability Pump Laser and unique ATC (automatic temperature control) and AGC (automatic gain control) circuit are employed in it as the key components 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 user-friendly.
Professional design GFF (gain flattening filter) with excellent optical path design provides the best optimization on flatness and noise.
The product is specially designed for single-fiber bi-direction system. High isolation B/R filter ensures 16 channels transmission both in red and blue band, meanwhile no interference between Boost and pre-amplifier.
The design of dual Power Mixed and hot swap provides longer MTBF. Also, the power system can be backed up.
Employing the intelligent temperature control system，the fan is on when the module temperature over 35℃, and it will stop as the temperature is under 30℃, which ensures the thermal stability and fan’s long life-time, moreover, the professional air flow design can also ensure the best temperature stability. Intelligent network management system. Perfectly network interface: Ethernet, RS-485 and RS-232 network interface, and the open mib ensures the connectivity with all other network management system.
