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

SFP28-25G-SR-SS-BO is a CBO SFP28 optical transceiver designed for short-reach multimode fiber links at a data rate of 25 Gbit/s. The module uses an LC UPC duplex connector and fits the compact SFP28 form factor, providing a hot-pluggable interface suitable for high-density server, switch and storage interconnects in data centre and enterprise networks. It supports standard 25 Gigabit Ethernet physical layer requirements for reliable short-distance connections.

Advantages

The transceiver combines a compact SFP28 package with multimode optical transmission, enabling flexible deployment in racks and blade systems where space is limited. Hot-pluggable operation allows replacement or upgrade without powering down equipment. The use of LC UPC connectors ensures compatibility with common multimode cabling, while the 25 Gbit/s throughput supports modern high-speed applications in data centres and aggregation points.

Suitable for

• Short-reach 25 Gigabit Ethernet links within data centres
• Server-to-switch and switch-to-switch connections in enterprise networks
• High-density rack deployments and blade enclosures
• Storage area networks (SAN) and high-performance computing clusters

Key specifications

• Data rate: 25 Gbit/s
• Form factor: SFP28
• Fiber type: Multimode fiber (MMF)
• Connector: LC UPC duplex
• Optical reach: optimized for short-reach links (multimode)
• Hot-pluggable: yes

How to use

Insert the SFP28 module into a compatible SFP28 port on a switch, server or storage device until it clicks into place, then connect LC duplex multimode patch cord between transceivers. Ensure both ends use matching fiber type and polarity. The module is hot-pluggable; follow standard handling precautions to avoid static discharge and contamination of optical interfaces. After installation, verify link status and negotiate speed and settings through the host device management interface.

Recommendations

Use multimode patch cords with clean LC UPC connectors and maintain proper fiber cleanliness. For reliable short-reach performance, match the transceiver to multimode fiber types specified by your network design and avoid excessive patching or extended passive distance beyond short-reach limits. Replace modules while powered on only if the host device supports hot-swap and follow vendor maintenance procedures.
