EDFA Board

Supplier
Visint
Category
Fiber Optic Amplifiers
Origin
China

The EDFA board directly regenerates multiwavelength optical signals without optical-electrical-optical conversion, extending transmission distance. Used with DWDM multiplexers/demultiplexers, it enables wavelength-division transmission, particularly in long-haul trunks, metropolitan and access networks and SDH/PDH systems.

Key Features

Basic functions: EDFA amplification of DWDM signals over 196.05-191.30THz, compatible with 40, 48, 80 and 96 wavelengths. Supports a 1510nm supervisory channel. Gain locking prevents channel additions/removals or fluctuations from affecting other channels. Transient control suppresses power changes for smooth upgrades. Performance/alarm monitoring reports optical power and detects module temperature, pump voltage, bias current, cooling current and temperature. Input demultiplexing separates 1510nm supervision from DWDM traffic; output multiplexing recombines them. MON taps part of the main signal for local online monitoring. DVOA adjusts service power online over 0-25dB. Unified SNMP-based management provides Telnet, Web and graphical NetRiver interfaces.
