CATV Amplifier

Optical Pre Amplifier

Product Description:

The product is multi-channel EDFA of high flattening and high stable output. The kernel component of the product is high availability pump laser and high-performance gain flattening filters. The product has high stable output, high gain flatness and high reliability by using unique APC (automatic power control) and ATC (automatic temperature control). The system’s flatness and noise can achieve the best optimization by the gain flattening filters of professional design. The system is convenient to regulation and display, reliable,

intelligent by using high stable and high precision MPU.

Applications:

C-band 44/80CH DWDM

Other optical systems

Product features:

 Low-noise high flatness design

Adjustable output power

High precision ATC keep system stable operation

Precision AGC / APC circuit keeps the output Power stability

Strict accordance with Bellcore GR-1312-CORE requirement for design
