The ADVA SFP/2Q5U/C1470V/SM/LC is a coarse wavelength division multiplexing (CWDM) small form-factor pluggable (SFP) optical transceiver module designed for metropolitan area networks and long-reach single-mode fiber applications. Operating at a specific wavelength of 1470 nm within the CWDM spectrum, the module supports data rates up to 2.5 Gbit/s, making it suitable for Gigabit Ethernet, Fibre Channel, and SONET/SDH transmission over dedicated wavelength channels. The transceiver features a duplex LC connector interface and is engineered for single-mode fiber deployments with typical transmission distances up to 80 km depending on fiber quality and network configuration. It complies with ITU-T G.694.2 CWDM grid specifications and SFF-8472 digital diagnostic monitoring standards, providing real-time access to operational parameters including temperature, laser bias current, transmitted and received optical power, and supply voltage. The module is hot-pluggable and designed for deployment in ADVA optical transport platforms and compatible CWDM multiplexing systems. It operates within an extended temperature range and incorporates advanced laser cooling and wavelength stabilization technology to maintain precise channel spacing in varying environmental conditions. Power consumption is optimized for high-density deployments in optical add-drop multiplexers and CWDM terminal equipment. Management and provisioning are performed through a two-wire serial interface (I2C), enabling seamless integration with network management and monitoring systems. This transceiver requires pairing with corresponding CWDM multiplexers/demultiplexers and is suitable for point-to-point links, ring topologies, and wavelength-specific transport applications in metro and regional networks.
