## Long description

CBO SFP28-25G-ESR-BR-BO is a 25 Gbps SFP28 optical transceiver with an LC duplex connector designed for short-range multimode fiber links up to 300 m. The module supports 25 Gigabit Ethernet signalling and is hot-pluggable for straightforward installation into compatible SFP28 ports. It is intended for high-speed connections in data center, enterprise and telecom environments where reliable short-reach fiber links between switches, servers and active equipment are required.
Advantages
The transceiver delivers a standardized 25 Gbps data rate with low power consumption and a compact SFP28 form factor suitable for dense port deployments. Its LC duplex interface and multimode fiber compatibility simplify cabling in existing short-range infrastructures. Hot-pluggable design enables on-the-fly replacement or upgrades without powering down systems, reducing maintenance time. The module is built to meet common optical and electrical specifications for interoperability with a wide range of network equipment.
Suitable for
 Short-reach switch-to-switch connections in data centers
 Server-to-switch uplinks requiring 25 Gbps capacity
 Top-of-rack and middle-of-row aggregation links over multimode fiber
 Environments needing hot-pluggable, high-density transceiver modules
Key specifications
 Nominal data rate: 25 Gbps
 Connector type: LC duplex
 Maximum reach: up to 300 m over multimode fiber (MMF)
 Form factor: SFP28 (hot-pluggable)
 Application: 25 Gigabit Ethernet and compatible optical links
 Optical interface: short-range multimode operation
How to use
Insert the SFP28 transceiver into a compatible SFP28 port on the switch or server until it clicks into place, then connect LC duplex multimode fiber patch cords following correct polarity. Ensure the host device is configured for the intended 25 Gbps link and verify link status through management interfaces or LED indicators. For hot-swap replacement, remove the module using the release latch and insert the new module while observing electrostatic discharge precautions.
Usage recommendations
Use OM3/OM4 multimode fiber for reliable reach up to 300 m, maintain clean connectors and follow manufacturer guidelines for fiber bending radius. Confirm compatibility with the host equipment and firmware versions before deployment and monitor link parameters after installation to ensure optimal performance.
