## Long description

The BlueOptics B309-BO 1250 Mbit/s SFP is a fiber optic transceiver module designed for single-mode links and compatible network equipment. Housed in a metal enclosure with a silver finish and weighing just 20 g, this SFP supports data rates up to 1250 Mbit/s and complies with CE, RoHS and FCC standards. The module features LC simplex connectivity and operates as a bidirectional optical transceiver suitable for Ethernet and other high-speed protocols over longer single-mode distances.
Advantages
The BlueOptics B309-BO offers a compact metal housing for reliable thermal performance and mechanical protection. Its support for standard SFP interfaces and compliance with industry regulations ensure wide interoperability with switches, routers and storage systems that accept MSA-compliant modules. Low weight and standardized form factor make installation and replacement straightforward while maintaining stable optical transmission at up to 1250 Mbit/s.
Suitable for
1 Gbit optical Ethernet links over single-mode fiber
Interconnecting switches, routers and storage systems in LAN and MAN environments
Fiber uplinks and long-distance point-to-point links up to typical single‑mode ranges
Systems requiring an SFP form factor and LC simplex connector
Key specifications
Interface type: SFP (Small Form-factor Pluggable)
Maximum data transfer rate: 1250 Mbit/s
Fiber type: single-mode fiber (LC simplex connector)
Typical wavelength arrangement: separate transmitter and receiver wavelengths for bidirectional operation (vendor-compatible 1310 nm / 1490 nm configuration)
Housing: metal, silver colour
Weight: 0.02 kg
Standards and compliance: CE, RoHS, FCC
How to use
Insert the BlueOptics B309-BO into a compatible SFP port on your switch, router or other networking device while the host is powered on or as recommended by the device vendor. Connect a single-mode LC simplex fiber patch cable between transceivers at each end of the link, observing proper polarity and connector cleanliness. Verify link status and negotiate line speed according to the host device interface. If the host supports digital diagnostics (DDM/DOM), enable and read the diagnostic parameters through the device management interface to monitor supply voltage, optical power and temperature.
Usage recommendations
To ensure reliable performance, use clean LC connectors and certified single-mode fiber patch cords. Confirm host compatibility with MSA-compliant SFP modules and enable DDM/DOM only if supported by the hardware. For long-term availability, operate within specified environmental ranges and avoid excessive mechanical stress during installation.
