EDFA Single channel erbium doped fiber amplifier
■Product Description
The product is single-channel EDFA of 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
♦ SDH
♦ Ethernet
♦ CATV
■Product features
♦ Low-noise high flatness design
♦ Adjustable output power
♦ High precision ATC keep system stable operation
♦ Precision ADC / APC circuit keeps the output Power stability
♦ Card design highly integrated, space-saving cabinet
♦ Expansion is very convenient
♦ Strict accordance with Bellcore GR-1312-CORE requirement for design
