10G CWDM SFP+ Transceiver CWDM-18 1610nm 10km SMF LC Optical Module with DDM for Telecom Network

Technical specifications

The 10G SFP+ CWDM-18 Optical Transceiver Module is a high-performance 10Gbps CWDM fiber optic transceiver designed for long-distance Ethernet and optical communication networks.

Operating at CWDM Channel 18 (1610nm), this module supports up to 10km transmission over Single Mode Fiber (SMF) through a standard Duplex LC optical interface. It adopts a compact SFP+ hot-pluggable form factor, providing reliable and flexible connectivity for switches, routers, OLTs, optical transport equipment, and enterprise backbone networks.

The module integrates a CWDM DFB laser transmitter and high-sensitivity receiver to deliver stable optical performance, low power consumption, and excellent transmission reliability. Optional Digital Diagnostic Monitoring (DDM/DOM) allows real-time monitoring of temperature, voltage, TX optical power, RX optical power, and laser bias current.

Designed for CWDM wavelength division multiplexing systems, metro networks, telecom infrastructure, and enterprise fiber networks, the 10G SFP+ CWDM-18 module helps maximize fiber resources while providing high-speed 10Gbps connectivity.
