The 1.25G CWDM-18 SFP Optical Transceiver Module is a high-performance Gigabit CWDM optical transceiver designed for wavelength division multiplexing (CWDM) optical communication systems. Operating at a 1.25Gbps data rate and 1610nm CWDM wavelength (Channel 18), it supports transmission distances of up to 10km over Single Mode Fiber (SMF).
The module adopts the industry-standard hot-pluggable SFP form factor with a Duplex LC optical interface, ensuring seamless compatibility with Gigabit Ethernet switches, routers, OLTs, media converters, and CWDM transport equipment.
Equipped with a high-performance DFB laser transmitter and PIN photodiode receiver, the module delivers excellent optical stability, low power consumption, and reliable long-term performance. It complies with IEEE 802.3z, SFP MSA, and supports optional Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of operating parameters. CWDM SFP modules are available across the ITU-T CWDM wavelength grid from 1270nm to 1610nm, including Channel 18 at 1610nm.
