SFP transceiver module BlueOptics SFP-SX2-AX-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-SX2-AX-BO is an SFP fiber optic transceiver module designed for 1250 Mbit/s (1.25 Gbit/s) data transmission using a 1310 nm wavelength. Housed in a metal casing and finished in silver, the module provides a compact, hot-pluggable interface for network devices that support SFP modules. It weighs approximately 20 g and operates at an input voltage of 4 V, making it suitable for integration into switches, routers and other network equipment that accept standard SFP form-factor transceivers.

Advantages

The module follows MSA-compatible SFP specifications and offers a standardized LC duplex optical interface for multimode fiber links. The metal housing ensures mechanical durability and EMI shielding while the single-fiber transmit/receive design at 1310 nm supports reliable optical signalling. Its compact SFP form factor and 4 V operating voltage simplify installation and compatibility with a wide range of networking hardware. The module is engineered for continuous operation in data networking environments.

How to use

Install the BlueOptics SFP-SX2-AX-BO by inserting the transceiver into an available SFP port on compatible network equipment while the device is powered according to the equipment manufacturer's hot-plug guidance. Connect LC duplex multimode fiber patch cords to the transceiver's optical connector, ensuring correct transmit-to-receive alignment between endpoints. Configure the network device to recognize and use the SFP port if necessary, and verify link status and data rate through the host device management interface.

Recommendations

For optimal performance, use quality multimode fiber patch cords and clean fiber connectors before connection. Confirm that the host hardware supports 1.25 Gbit/s SFP modules and, if available, enable digital diagnostics (DDM/DOM) in the host device to monitor supply voltage, optical power and temperature where supported.
