Comnet CWGE-SM Commercial SFP Module
The CWGE-SM is a commercial-grade SFP transceiver module designed to extend network links across singlemode fiber. It fits into the LC connector slot of compatible Comnet media converters (such as the CWGE2SCM2) and carries Gigabit Ethernet traffic at 1310 nm wavelength over distances up to 15 km — the reach window you need for campus deployments, remote surveillance sites, or industrial installations where copper cabling becomes impractical.
Overview
SFP (Small Form-factor Pluggable) modules are field-swappable transceivers that connect media converters to fiber runs. The CWGE-SM operates at 1310 nm (standard for singlemode long-reach work) and supports dual-fiber configuration, meaning you run two strands — one transmit, one receive — rather than wavelength-division multiplexing. MSA compliance ensures interoperability with standard Comnet converters and third-party equipment following the same specification.
Compatibility
The CWGE-SM is designed for Comnet CWGE2SCM2 (2-fiber singlemode) media converters. It installs directly into the SFP port on these converters, providing the fiber-to-Gigabit Ethernet interface. Verify your media converter model includes an SFP slot rated for singlemode; multimode (CWGE-MM) modules will not interoperate correctly on singlemode fiber runs due to wavelength mismatch. When integrating into larger surveillance or industrial networks, confirm your fiber plant (already installed or planned) is certified singlemode to standard ITU-T G.652 or equivalent.
Installation Notes
Handle the CWGE-SM with care — fiber endpoints are precision-aligned. Keep protective dust caps on LC connectors until installation. Route singlemode fiber with a minimum bend radius of 30 mm to avoid signal loss. Ensure both transmit and receive strands are properly terminated and tested with a light source before connecting the SFP; misalignment or a break in either strand will block traffic. Operating temperature range is 0°C to 70°C; do not expose the module or connected fiber to direct sunlight or temperature swings beyond this window without appropriate environmental enclosure.
