SFP transceiver BlueOptics AXSK-CSFP-SR-BO 1250 Mbit/s optický strieborná

The BlueOptics AXSK-CSFP-SR-BO is an SFP fiber optic transceiver designed for 1000Base-SX multimode fiber links with a maximum data transfer rate of 1250 Mbit/s. The module has an LC duplex interface, operates with 850 nm transmit and receive wavelengths, and fits standard SFP ports. Its metal housing provides mechanical durability while the low weight of 20 g makes it easy to handle and install in switches, routers and other network devices.

Advantages

The transceiver follows MSA SFP specifications to ensure interoperability with supported hardware and offers a long MTBF of 1,000,000 hours for extended service life. It supports common high-speed protocols such as Ethernet and Fibre Channel over Ethernet up to 1.25 Gbit/s and is designed for multimode fiber runs up to typical short-reach distances. Built with industry-grade components and compliant with CE and RoHS, the module includes diagnostics capability when the host supports DDM/DOM functions.

How to use

Power off or follow hot-swap instructions for your host device and insert the transceiver into an available SFP slot until it clicks into place. Connect LC duplex multimode patch cords to the module’s transmit and receive ports, ensuring correct polarity. Verify link status on the host device and, if available, enable or read out DDM/DOM diagnostics to monitor supply voltage, temperature, laser bias and optical power. Remove the optical dust caps only when ready to make the connection and store caps to protect the connectors when not in use.

Recommendations

Use high-quality multimode patch cords and maintain correct TX/RX polarity. Confirm that the target switch, router or appliance officially supports MSA-compliant SFP modules or enables third-party transceivers. For diagnostic access, ensure the host platform supports DDM/DOM. Avoid bending fiber beyond recommended radii and keep connectors clean to maintain optimal optical performance.
