## Summary description

CBO SFP28-25G-ESR-GM-BO is an SFP28 optical transceiver supporting 25 Gbit/s data rate with LC duplex interface and a reach of up to 300 m. Designed for high-speed 25G Ethernet and data center links, it provides hot-pluggable connectivity for switches and servers. Use cases include server uplinks, TOR switches and short-reach optical links where compact modular optics are required.

## Long description

CBO SFP28-25G-ESR-GM-BO is an SFP28 optical transceiver module designed for 25 Gbit/s Ethernet links with an LC duplex connector and an optical reach of up to 300 meters. The module supports hot-pluggable installation in compatible SFP28 ports on switches, servers and other networking equipment, enabling compact and modular deployment for data center and enterprise networks. It is intended for short-reach multimode or specified single-mode applications where a small form-factor transceiver offering 25G performance is required.
Advantages
The transceiver provides a consistent 25 Gbit/s data rate with a duplex LC interface and compact SFP28 form factor, allowing flexible port density in network racks and server platforms. Hot-pluggable capability reduces maintenance downtime and simplifies upgrades. With a reach up to 300 m, it supports a range of short-reach interconnects within campus and data center environments while maintaining compatibility with standard SFP28 ports.
Suitable for
 25G Ethernet server uplinks
 Top-of-rack (ToR) switch connections
 Short-reach optical links within data centers
 High-density switch and router ports requiring SFP28 modules
Key specifications
 Nominal data rate: 25 Gbit/s
 Connector type: LC duplex
 Form factor: SFP28
 Maximum optical reach: up to 300 meters
 Hot-pluggable module for easy insertion and removal
How to use
Install the SFP28 transceiver into a compatible SFP28 port on a switch, server or network appliance until it clicks into place. Connect LC duplex fiber patch cables matching the link type to the transceiver ports, ensuring correct polarity. Configure the host interface for 25G operation if required by the equipment. For removal, power down the port if recommended by the platform, depress the module latch and carefully extract the transceiver.
Usage recommendations
Use fiber cable and patch panels that meet the required multimode or single-mode specifications for the intended reach, and verify link settings on network devices to ensure stable 25G operation. Store unused transceivers in anti-static packaging and protect optical interfaces with dust caps when not connected.
