SFP-transceivermodule BlueOptics 740-021341-BO 1250 Mbit/s glasvezel

The BlueOptics 740-021341-BO SFP transceiver module is a compact fiber optic interface designed for 1.25 Gigabit Ethernet links. Supporting a maximum data transfer rate of 1250 Mbit/s and a maximum transfer distance of up to 20,000 m, this module provides a lightweight (20 g), silver-coloured option for adding fiber connectivity to switches, routers and media converters that accept standard SFP modules. The unit is engineered to operate with an expected mean time between failures (MTBF) of 1,000,000 hours, delivering reliable physical layer performance for long-reach single-mode fiber applications.

Advantages

The module's compact SFP form factor allows hot-pluggable installation in compatible network equipment without adding bulk. Its LC fiber connector supports common single-mode cabling and enables long-distance links up to 20 km while maintaining a 1.25 Gbit/s signaling rate. At just 20 g and finished in silver, the transceiver is easy to handle and install. The specified MTBF of 1,000,000 hours indicates a stable operational lifetime for infrastructure deployments.

Suitable for

• Extending Ethernet networks over single-mode fiber for campus and metro links
• Connecting switches and routers with SFP ports for uplinks
• Integrating with media converters and fiber access equipment
• Deployments requiring long-reach optical links up to 20,000 m

How to use

Power down or follow the equipment vendor’s hot-swap guidance and insert the SFP transceiver into a compatible SFP port until it seats securely. Connect a single-mode LC patch cable to the transceiver’s LC connector, matching transmit and receive fibers with the remote device. Configure the attached network equipment as required for 1.25 Gbit/s optical links and verify link status through switch/router diagnostics. When removing the module, use the release mechanism specified by the host device and store protective caps on the transceiver and cable ends to prevent contamination.

Recommendations

Use single-mode fiber and LC-compatible patch cords rated for long-reach connections. Keep optical interfaces clean by using fiber cleaning tools or wipes before insertion, and avoid bending the fiber beyond manufacturer bend-radius specifications. Verify compatibility with the host device SFP specifications and firmware; if necessary, consult equipment documentation for supported transceiver models and link configuration.
