Fiber optic SFP28 transceiver CBO SFP28-25G-ESR 25 Gbps

The Fiber optic SFP28 transceiver CBO SFP28-25G-ESR 25 Gbps is a hot-pluggable module designed to provide 25 Gigabit Ethernet connectivity over optical fiber. Intended for use in switches, routers and servers, this SFP28 transceiver supports high-speed serial links for data center uplinks and network aggregation. The module follows the small form-factor pluggable SFP28 footprint, enabling interoperable installation and straightforward replacement without system downtime.

Advantages

This SFP28 transceiver delivers a 25 Gbps data rate with stable optical performance appropriate for short- to extended-reach applications, while maintaining a compact and hot-swappable form factor that simplifies maintenance and upgrades. Compatibility with standard SFP28 ports ensures broad interoperability across network equipment, and the optical design reduces electromagnetic interference compared with copper solutions. The module is designed to integrate into existing fiber infrastructure and to support higher-density topologies in modern data centers.

Suitable for

• 25 Gigabit Ethernet uplinks in data center switches and top-of-rack equipment
• Aggregation links between routers and distribution switches
• High-performance server network interfaces requiring optical connectivity
• Environments requiring hot-pluggable, space-saving transceiver modules

Key specifications

• Nominal data rate: 25 Gbps
• Form factor: SFP28 hot-pluggable transceiver
• Optical interface: single-mode or multimode fiber compatibility depending on variant
• Typical application: 25 Gigabit Ethernet serial links for uplinks and aggregation
• Operating environment: designed for installation in rack-mount network equipment and servers

How to use

Install the SFP28 transceiver into an empty SFP28 port on a compatible switch, router or server while the device is powered on if hot-plugging is supported. Ensure the fiber patch cable is matched to the transceiver's optical interface (single-mode or multimode) and securely connect the cable after insertion. Verify link status and speed through the host device management interface or LED indicators. For removal, disconnect the fiber cable first and then extract the module using the port latch or release mechanism to avoid damage to the fiber connector.

Recommendations

Use appropriate fiber patch cords and maintain clean connector end-faces to preserve signal quality. Confirm compatibility with the host device firmware and SFP28 port specifications. Store spare modules in anti-static packaging and avoid exposing the transceiver to extreme temperatures or humidity during installation.
