SFP28 Transceiver BlueOptics 980-9I34B-00AS00-BO, LC-Duplex, 25GBASE-SR, MMF, 850nm, 100m, DDM/DOM, 0–70°C

The BlueOptics SFP28 25GBASE-SR transceiver is a compact optical module for short-range 25 Gb/s connectivity over multimode fiber. Designed for use in data center and enterprise network equipment, it uses an LC-duplex connector and transmits at an 850 nm wavelength. The module supports links up to 100 m on suitable multimode fiber and includes digital diagnostic monitoring to report real-time operating parameters. The transceiver is specified for operation in environments from 0 °C to 70 °C, providing a reliable option for rack and server interconnects that require high-density 25G ports.

Advantages

The transceiver offers a small form-factor suitable for high-density switch and server ports while maintaining 25 Gb/s throughput for short-reach links. Native LC-duplex connectivity enables straightforward integration with standard multimode fiber cabling. Built-in diagnostic monitoring provides visibility into parameters such as temperature, optical power and supply voltage, aiding in remote troubleshooting and network management. The defined operating temperature range and multimode compatibility make the module appropriate for typical data center and telecom indoor environments.

Key specifications

How to use

Install the SFP28 module into a compatible SFP28 port on a switch, router or network interface card following the equipment manufacturer’s hot-plugging guidelines. Connect LC-duplex multimode fiber patch cords to the module, ensuring correct transmit/receive alignment. Verify link status via the host device; use the digital diagnostic monitoring feature to read optical power levels, temperature and other diagnostics through the management interface. Replace modules only when the host device indicates link failure or diagnostics show out-of-range values.

Recommendations

For reliable operation, use multimode fiber with appropriate modal bandwidth for 25GBASE-SR and maintain clean LC connectors. Observe bend-radius limits for fiber cabling and verify patch-cord polarity. Monitor DOM values periodically to detect early signs of degradation. Use within the specified 0–70 °C operating range and follow equipment vendor compatibility lists when deploying in production networks.
