The Cisco 15454-OPT-EDFA-17 Optical Amplifier Module is a plug-in Erbium-Doped Fiber Amplifier (EDFA) for Cisco ONS 15454 optical transport systems, providing optical signal amplification for long-haul and metro DWDM networks. It operates in the Enhanced C-Band, supports up to 96 DWDM channels, uses fiber-optic interfaces for DWDM transport, and is designed to fit the Cisco ONS 15454 chassis as a modular add-on. Common uses include extending transmission distances, maintaining signal strength across multiple channels, and enabling network expansion or upgrades in telecom infrastructure.
