SFP transceiver module BlueOptics SFPGSX2-W-BO 1250 Mbit/s 850 nm

The BlueOptics SFPGSX2-W-BO is an SFP (Small Form-factor Pluggable) fiber optic transceiver module designed for 1000Base-SX networks. It supports a maximum data transfer rate of 1250 Mbit/s over multi-mode fiber using an 850 nm wavelength. Housed in a durable silver metal casing and weighing approximately 2 g, the module operates from a 3.3 V input and is supplied individually packaged for easy installation and inventory management.

Advantages

The transceiver follows MSA SFP form-factor standards and provides bidirectional optical transmission with LC duplex connectivity. It supports common high-speed protocols such as Ethernet and Fibre Channel over Ethernet up to 1.25 Gbit/s and is compatible with equipment that accepts standard 1000Base-SX SFP modules. The compact metal housing offers mechanical protection and thermal stability while the low weight simplifies handling and reduces insertion stress in ports.

Suitable for

• Short-range multimode fiber links in LAN and data center environments
• Connections between switches, routers, storage systems and servers
• Upgrading or replacing standard 1000Base-SX SFP ports
• Environments requiring LC duplex fiber connections

Key specifications

• Interface type: SFP (LC duplex)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength: 850 nm for transmitter and receiver
• Suitable fiber type: Multi-mode fiber
• Typical reach on MMF: up to 550 meters (protocol and fiber dependent)
• Supply voltage: 3.3 V
• Product colour: Silver; housing: metal
• Weight: approximately 0.002 kg

How to use

Ensure the host device supports 1000Base-SX SFP modules and, if monitoring is required, that the device supports Digital Diagnostic Monitoring (DDM/DOM). Insert the transceiver into an available SFP slot with the LC duplex connector accessible, then attach the corresponding LC fiber patch cord, observing transmit/receive orientation. Verify link status and protocol settings on the host device; adjust network configuration as needed to enable the desired speed and duplex settings.

Recommendations

For optimal performance, use high-quality multimode patch cords and follow the vendor-recommended fiber type and patching practice. If DDM/DOM monitoring is needed, confirm host compatibility to access real-time diagnostic data such as supply voltage, laser bias current, optical output and input power, and temperature. Avoid excessive bending of fiber cables and protect the transceiver from contamination when not connected.
