SFP28 optical transceiver CBO SFP28-25G-SR-EE-BO 25 Gbit/s multimode 100 m

CBO SFP28-25G-SR-EE-BO is a 25 Gbit/s SFP28 optical transceiver engineered for short-reach multimode fiber links up to 100 m. The module offers a compact, hot-pluggable fiber interface for high-speed server, switch and storage interconnects and supports standard 25 Gigabit Ethernet physical layer applications. It is intended for deployment in data center top-of-rack switches, aggregation equipment and enterprise network switches where reliable, space-efficient multimode connectivity is required.

Advantages

The transceiver provides a high-density SFP28 form factor that saves rack port space while delivering 25 Gbit/s line rate performance. It supports hot-swap installation to minimize downtime during upgrades or maintenance. Built for multimode fiber, the module enables low-power short-reach links and interoperates with standard 25GBASE-SR optics for predictable link behavior. The compact design and standard electrical interface simplify integration into existing network equipment.

Suitable for

• Short-reach 25 Gigabit Ethernet links in data centers
• Top-of-rack and leaf switches requiring multimode connectivity
• High-speed server-to-switch or switch-to-switch links up to 100 m
• Storage networking and aggregation layers in enterprise LANs

• Application: 25 Gigabit Ethernet short-reach

How to use

Insert the SFP28 optical transceiver into a compatible SFP28 port on your switch, server NIC or storage device while the host is powered on or during maintenance windows, as supported by the equipment. Connect duplex multimode fiber patch cables with LC connectors to the module, ensuring correct polarity. Verify link status and interface settings in the host device management interface and configure speed and auto-negotiation according to your network design. Observe manufacturer guidelines for ESD handling and avoid bending fiber beyond rated bend radii to maintain signal integrity.

Recommendations

Use this transceiver with OM3/OM4 multimode fiber for reliable performance at distances up to 100 m. Confirm compatibility with the host device vendor and check firmware or optics compatibility lists when deploying at scale. Maintain clean connectors and perform regular inspection of fiber endfaces to reduce insertion loss and ensure stable 25 Gbit/s links.
