SKU: RMEA
DEDF is a bidirectional erbium-doped fiber amplifier that integrates a preamplifier and booster amplifier into one compact unit along with an optical power monitor (OPM) for real-time detection/reporting and variable optical attenuator (VOA) for fast power balancing. It is designed to amplify the optical power up to 48 channels (channel interval of 100 GHz) or 96 channels (channel interval of 50 GHz) at the C-band at the same time in the transmission link. It has characteristics of flat gain, stable output, low noise figure, etc. It is mostly used in DWDM high-speed and long-haul transmission and is housed within two slots in a managed chassis. It supports unified management of its optical-layer and electrical-layer boards based on SDN, which allows integrated configuration, multi-rate hybrid transmission, efficient operation, and maintenance. It has a built-in optical supervisory channel (OSC) that has express ports accessed in the front of the module and dedicated SFP for remote site alarm reporting, communication necessary for fault location, and order wire.
