## Long description

The BlueOptics SFP-BXU35-40KM-UQ-BO is an SFP fiber optic transceiver module designed for single-port fiber links with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal casing with a compact SFP form factor and a weight of 20 g, this module is intended for reliable long-distance transmission. With an MTBF of 1,000,000 hours, it is suitable for deployment in switches, routers and other networking equipment that accept SFP interfaces.
Advantages
The module’s metal housing provides mechanical durability and helps with thermal dissipation. Its SFP interface ensures hot-pluggable installation and compatibility with a wide range of network devices. A rated maximum transfer speed of 1250 Mbit/s supports standard Gigabit Ethernet links over single-mode fiber. The compact, silver-coloured design keeps module size and weight minimal for dense installations.
Suitable for
 Long-distance single-mode fiber links
 Upgrading SFP slots in switches and routers
 Point-to-point network connections between sites
 Telecommunications and enterprise backbone segments
Key specifications
 Form factor: SFP (small form-factor pluggable)
 Maximum data transfer rate: 1250 Mbit/s
 Housing: metal
 Weight: 0.02 kg
 Device colour: silver
 Designed for single-mode long-distance transmission
 Mean Time Between Failures (MTBF): 1,000,000 hours
How to use
Power down or set the host device to allow hot-plugging according to the equipment manual, then insert the BlueOptics SFP-BXU35-40KM-UQ-BO into an available SFP slot until it clicks into place. Connect the appropriate single-mode fiber cable to the optical interface, observing correct transmitter/receiver orientation. Verify link status through the host device’s management interface and monitor signal indicators to confirm successful negotiation at up to 1250 Mbit/s.
Usage recommendations
Use single-mode fiber with appropriate connectors and follow vendor guidelines for optical power budgets and cable attenuation. Avoid bending fiber beyond minimum bend radius and ensure connectors are clean before insertion. For stable long-term operation, install the module in equipment with adequate airflow to assist heat dissipation from the metal housing.
