SFP28 Transceiver BlueOptics 4TC7A69045 (BO27O856S1D) LC-Duplex 10G/25GBASE-SR Multimode 850nm 100m DDM 0–70°C

Single-port SFP28 optical transceiver BlueOptics 4TC7A69045 (BO27O856S1D) is designed for short-range multimode fiber links in data centers and enterprise networks. The module supports both 10GBASE-SR and 25GBASE-SR operation over multimode fiber at a wavelength of 850 nm with an LC duplex connector, providing up to 100 m reach. Integrated digital diagnostics monitoring (DDM) allows real-time monitoring of optical parameters, and the transceiver is specified to operate across a temperature range from 0 °C to +70 °C.

Advantages

The SFP28 form factor offers a compact, hot-pluggable solution for high-density switch and server ports while supporting higher data rates up to 25 Gbit/s. Dual-rate capability (10G/25G) increases deployment flexibility and backward compatibility with existing 10G equipment. The LC duplex interface and multimode 850 nm optics are suited to short-reach connections, reducing the need for more expensive single-mode fibers for intra-rack and short inter-rack links. On-board DDM provides status information such as optical power and temperature for simplified monitoring and troubleshooting.

How to use

Install the SFP28 transceiver into a compatible SFP28/SFP+ slot on switches, routers or network interface cards while the equipment is powered according to the host vendor guidelines. Use LC duplex multimode patch cables to connect the transceiver to the multimode fiber infrastructure. Confirm link negotiation at 10G or 25G depending on connected equipment capabilities and configure the host port speed if required. Monitor optical parameters via host management software to verify transmitter/receiver power and temperature using the DDM feature.

Recommendations

For reliable short-range performance, use quality OM3 or OM4 multimode fiber and LC duplex patch cords, maintain proper fiber handling to avoid bend loss, and ensure the host device firmware supports SFP28 modules and 25GBASE-SR operation. Verify compatibility with the switch or server vendor if vendor locking or third-party module restrictions apply.
