SFP28 transceiver module BlueOptics BO27O856S3D-BO 300m Aluminium

The BlueOptics BO27O856S3D-BO SFP28 transceiver module is a fiber-optic module for high-speed short-range data links. Designed for SFP28 ports, it supports 10G and 25GBASE-SR applications over multimode fiber with an LC duplex connector and an optical wavelength of 850 nm. The module is housed in an aluminium casing and weighs approximately 40 g, offering a compact solution for data center and enterprise network environments that require up to 300 m reach on multimode fiber.

Advantages

The module complies with MSA SFP28 form factor standards and is suitable for use in switches, routers, storage systems and other network devices that accept compatible SFP28 transceivers. It supports simultaneous transmit and receive through an LC duplex interface and implements Digital Diagnostics Monitoring (DDM/DOM) to report supply voltage, laser bias current, transmit power, receive power and temperature for remote monitoring. Built with proven optical and electronic components, the transceiver is intended for extended service life and stable optical performance in high-speed Ethernet and Fibre Channel over Ethernet applications.

Suitable for

• Short-reach multimode connections in data centers (up to 300 m)
• 10G and 25GBASE-SR optical uplinks between switches and servers
• Interconnects for storage systems and SAN ports
• Network equipment requiring SFP28 LC duplex modules with DDM support

Key specifications

• Interface type: SFP28
• Supported protocols: 10G and 25GBASE-SR (multimode)
• Wavelength: 850 nm (transmit and receive)
• Connector: LC duplex
• Maximum reach: up to 300 m on multimode fiber
• Housing material: aluminium
• Weight: approx. 0.04 kg
• Digital Diagnostics: DDM/DOM (SFF-8472 compliant)

How to use

Install the SFP28 transceiver into a compatible SFP28 port on your switch, router or storage device until it latches. Connect an LC duplex multimode fiber patch cord between this transceiver and the corresponding transceiver or patch panel. Ensure that the host device firmware and software support 10G/25GBASE-SR operation and enable DDM/DOM if monitoring is required. Observe proper electrostatic discharge (ESD) precautions during handling and remove dust caps from fiber connectors before mating to avoid contamination and signal loss.

Recommendations

Use OM3/OM4 multimode fiber for reliable 25G links at the stated distances, verify DDM/DOM compatibility with your hardware for remote diagnostics, and perform regular inspection and cleaning of LC connectors to maintain optimal link quality.
