Transceptor SFP CBO SFP-LHX1310-40-D 1250 Mbit/s 1310 nm monomodo 40 km

The CBO SFP-LHX1310-40-D is an SFP optical transceiver module that supports a 1250 Mbit/s data rate at a 1310 nm wavelength for single-mode fibre. It is designed for point-to-point links up to 40 km and provides a hot-pluggable interface suitable for network switches, routers and fibre media converters. The module enables long-distance Ethernet and telecom connections with low latency and stable optical performance over single-mode fibre.

Advantages

This SFP transceiver offers a compact, hot-swappable form factor that simplifies maintenance and upgrades without powering down equipment. Built for single-mode transmission, it provides extended reach up to 40 km while maintaining a 1250 Mbit/s line rate and stable optical power. The device is compatible with common SFP cages and supports straightforward installation in standard network hardware, reducing downtime and physical footprint compared to larger optics.

Key specifications

How to use

Install the SFP module into an available SFP port on a switch, router or media converter until it clicks into place. Connect a single-mode fibre patch cable with appropriate connectors (e.g., LC) between the module and the remote transceiver, taking care to align transmit and receive ports correctly. Verify link status via the network device LEDs or management interface and configure interface settings (speed/duplex if required) on the host device. Handle the optical connectors carefully and keep protective dust caps when the module is not connected.

Recommendations

Use certified single-mode fibres and quality patch cords to achieve the specified reach. Confirm optical power budget and dispersion limits for 40 km spans and avoid bending the fibre below recommended bend radii. For best results in live networks, install or remove the module with the host device powered according to vendor guidelines to prevent port damage, and monitor link parameters after deployment.
