Fiber optic SFP transceiver CBO DEM-211 155 Mbit/s, LC connector, 1310 nm, 2000 m

CBO DEM-211 is a fiber optic SFP transceiver that supports a 155 Mbit/s data rate and uses an LC connector with a 1310 nm optical wavelength. Built for single-mode fiber links, it provides point-to-point optical connectivity for switches, routers and telecom equipment over distances up to 2000 m. The module is intended for straightforward installation into standard SFP ports and is suitable for network upgrades, backbone links and extending Ethernet or PDH lines without complicated configuration.

Advantages

The transceiver combines a compact SFP form factor with compatibility for common networking devices, allowing hot-plug replacement and minimal downtime. Operating at 1310 nm on single-mode fiber, it supports reliable transmission up to 2000 m and maintains a stable 155 Mbit/s data rate. The LC duplex interface provides a small-footprint connection and broad interoperability with standard fiber patch cords and adapters.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or telecom device while the equipment is powered according to the vendor instructions for hot-swapping. Connect LC duplex fiber patch cords to the module, ensuring transmit and receive fibers are correctly aligned. Verify link status and configuration on the host device; no special drivers are typically required when using standard SFP-compatible hardware. For reliable operation, use appropriate single-mode fiber and keep connectors clean.

Recommendations

For stable long-distance links, use single-mode fiber rated for the intended distance, maintain clean LC connectors, and verify device compatibility with SFP modules supporting a 155 Mbit/s rate and 1310 nm wavelength. Follow standard ESD precautions when handling the module and consult device documentation for any platform-specific settings.
