Transceiver CBO SFP28-25G-ESR Fiber Optic 25G — SFP28 module for 25 Gigabit links

The Transceiver CBO SFP28-25G-ESR Fiber Optic 25G is an SFP28 module engineered to provide a 25 Gigabit optical interface for high-speed Ethernet links. Designed for installation in switches, routers and servers, this compact fiber optic transceiver supports 25G data rates for use in data centers and enterprise networks where low latency and reliable connectivity are required. The module supports hot-pluggable operation to simplify upgrades and replacements without powering down host equipment.

Advantages

This SFP28 transceiver delivers a standardized 25G optical connection in a small form factor, enabling high-density port deployments. It offers stable, low-latency transmission suitable for server interconnects and aggregation switches. Compatibility with common switch and router platforms ensures straightforward integration, and the hot-pluggable design reduces maintenance windows and operational disruption.

Suitable for

• 25 Gigabit Ethernet uplinks between switches and routers
• Server-to-switch interconnects in data center racks
• Aggregation and spine-leaf network fabrics
• High-performance computing clusters and storage networks

Key specifications

• Form factor: SFP28
• Data rate: 25 Gbps
• Optical interface: single-mode fiber support
• Transmission distance: specification dependent on fiber type and optics class
• Connector type: LC duplex compatible
• Power consumption: low-power SFP28 class
• Operating temperature range: suitable for standard network equipment environments

How to use

Install the transceiver into an available SFP28 slot on a compatible switch, router or server until it seats securely. Connect an LC duplex single-mode fiber patch cable between the module and the remote device, observing correct transmit/receive orientation. Verify link status through the host device management interface and monitor optical parameters if supported. For hot-plug operations, follow the host equipment manufacturer’s guidelines to avoid transient link issues.

Recommendations

For optimal performance, use single-mode fiber with appropriate attenuation and connector cleanliness. Match the transceiver to supported data rates and ensure firmware or compatibility lists for the host device include the module. Regularly inspect and clean LC connectors and monitor temperature and power margins in high-density deployments.
