10G SFP+ CWDM-18 Optical Transceiver Module 1610nm 40km Single Mode Fiber Duplex LC 10Gbps Ethernet Optical Module

Technical specifications

The 10G SFP+ CWDM-18 40km Optical Transceiver Module is a high-performance wavelength division multiplexing optical module designed for 10Gbps long-distance fiber communication networks.

Operating at CWDM Channel 18 (1610nm), this module supports up to 40km 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 CWDM systems, Ethernet switches, routers, OLT equipment, and optical transport networks.

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

Designed for metro Ethernet, telecom backbone, ISP networks, and CWDM wavelength multiplexing systems, this 10G CWDM-18 optical module helps expand fiber capacity without deploying additional fiber cables.
