Fiber optic transceiver module BlueOptics MMA1L20-AR-BO SFP28 LC Aluminium 20g

The BlueOptics MMA1L20-AR-BO SFP28 LC Aluminium 20g is a fiber optic transceiver module designed for 25G data transmission over single-mode fiber. Built to MSA standards, this SFP28 transceiver uses an LC duplex connector and an aluminum housing to provide a compact, lightweight module for use in switches, routers and storage systems. The module supports optical transmit and receive functions at 1310 nm and includes Digital Diagnostic Monitoring (DDM) for real-time monitoring of operating parameters when supported by the host hardware.

Advantages

The module offers 25GBASE-LR performance in an SFP28 form factor with broad platform compatibility when used with Mellanox-compatible hardware. Constructed with high-quality optical components and tested for interoperability, it provides stable signal transmission, electromagnetic immunity inherent to fiber links, and long service life. Integrated DDM/DOM capability facilitates remote diagnostics of voltage, temperature and optical power.

How to use

Install the BlueOptics SFP28 transceiver into a compatible SFP28 cage on the host device until it latches securely, then connect LC duplex single-mode fiber patch cables to the module. Ensure the transmit and receive fibres are correctly oriented and that the host system supports 25G SFP28 modules and DDM if monitoring is required. Follow the host vendor’s procedures for hot-plugging and check link status through the switch or server management interface.

Recommendations

Use high-quality single-mode LC patch cables of appropriate length to achieve the specified LR reach, verify compatibility with the host platform, and enable DDM in the host management software to monitor optical power, temperature and supply voltage. Avoid bending fiber beyond recommended radii and protect the transceiver from electrostatic discharge during installation.
