## Summary description

Single-port SFP28 optical transceiver BlueOptics 4TC7A69045 (BO27O856S1D) for short-range multimode links. Supports 10G/25GBASE-SR operation over multimode fiber at 850 nm with LC-duplex connector and up to 100 m reach. Features digital diagnostics monitoring (DDM) and operates in the 0°C to +70°C temperature range; suitable for data center and enterprise 10G/25G connections.

## Long description

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.
Suitable for
Short-reach links within data centers and server rooms (up to 100 m over multimode fiber)
Upgrading switch and server ports from 10G to 25G while maintaining 10G compatibility
High-density aggregation and spine-leaf network architectures
Enterprise LAN segments requiring multimode LC duplex connections
Key specifications
Form factor: SFP28 single-port optical transceiver
Supported standards: 10GBASE-SR and 25GBASE-SR
Wavelength: 850 nm
Maximum reach: up to 100 m over multimode fiber (OM3/OM4 dependent)
Connector type: LC duplex
Diagnostics: Digital diagnostics monitoring (DDM)
Operating temperature: 0 °C to +70 °C
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.
Usage 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.
