## Summary description

CBO DEM-211 is a fiber optic SFP transceiver supporting 155 Mbit/s data rate with an LC connector and 1310 nm wavelength. Designed for single-mode links up to 2000 m, it enables point-to-point optical connections between switches, routers or telecom equipment. Useful for network upgrades, backbone links and extending Ethernet/PDH lines with plug-and-play installation.

## Long description

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.
Suitable for
Point-to-point optical links between switches and routers
Extending Ethernet or PDH lines over single-mode fiber
Backbone and aggregation links in campus and telecom networks
Network upgrades where 155 Mbit/s bandwidth and up to 2000 m reach are required
Key specifications
Data rate: 155 Mbit/s
Wavelength: 1310 nm
Optical interface: LC (duplex)
Fiber type: single-mode
Maximum link distance: up to 2000 m
Form factor: SFP (hot-pluggable)
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.
Usage 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.
