SFP28 transceiver CBO SFP28-25G-SR-MR-BO 25 Gbit/s multimode LC UPC

CBO SFP28-25G-SR-MR-BO is a 25 Gbit/s SFP28 optical transceiver module designed for multimode fiber links with an LC UPC connector. The compact SFP28 form factor enables direct installation into compatible switch, server, or storage ports to provide high-speed short-reach connectivity in data center, campus and enterprise networks. The module supports standard 25GbE physical layer implementations over multimode fiber and is suitable for upgrading existing ports or enabling new 25 Gbit/s links with a straightforward plug-and-play deployment.

Advantages

The transceiver delivers 25 Gbit/s data rates in a small SFP28 housing, offering a balance of performance and density for modern networking equipment. Its LC UPC multimode optical interface provides reliable connections for short-reach links while minimizing space and power overhead compared with larger form factors. Compatibility with standard multimode fiber types and a plug-and-play design simplifies installation and reduces provisioning time.

Suitable for

• 25 Gigabit Ethernet uplinks and server interconnects
• Short-range data center links and top-of-rack (ToR) connections
• High-density switch ports requiring SFP28 modules
• Storage networking and aggregation links over multimode fiber

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a network switch, server or storage device while the host device is powered on or following the vendor's recommended hot-plug procedure. Connect LC duplex multimode fiber patch cables to the module's LC UPC connector, ensuring proper polarity and secure seating. The host device should recognize the module automatically; verify link status and speed through the device management interface. If link problems occur, check fiber type, cable length, connector cleanliness, and host compatibility.

Recommendations

Use OM3/OM4 multimode fiber for optimal short-reach performance and ensure LC connectors are clean prior to connection. Match transceiver speed and duplex settings on both ends of the link and follow equipment vendor compatibility lists when possible. For reliable operation, avoid exceeding the recommended link distance for multimode deployment and minimize bending and stress on fiber runs.
