SFP28 optický transceiver CBO SFP28-25G-LR-RW-BO 25 Gbit/s LC singlemode do 10 000 m

The CBO SFP28-25G-LR-RW-BO is an SFP28 optical transceiver engineered for 25 Gbit/s data links over single-mode fiber. Featuring an LC duplex connector and support for long-reach transmission up to 10,000 meters, this module is intended for 25G Ethernet and high-speed uplink applications in data centers and enterprise networks. It is hot-pluggable and implements standard digital diagnostics and management interfaces for integration with modern switches and servers.

Advantages

This transceiver offers a stable 25 Gbit/s throughput with single-mode fiber compatibility for extended distances. Hot-pluggable design reduces downtime during installation or replacement. Support for standard management interfaces provides access to diagnostic information such as transmit/receive power and temperature, facilitating network monitoring and maintenance. The compact SFP28 form factor enables high port density in networking equipment.

Suitable for

• 25G Ethernet server and switch uplinks
• Long-reach single-mode fiber links up to 10 km
• Data center aggregation and spine-leaf architectures
• Carrier and metro edge connections requiring single-mode LC interfaces

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: single-mode
• Connector: LC duplex
• Maximum reach: up to 10,000 m (10 km)
• Form factor: SFP28
• Hot-pluggable: yes
• Digital monitoring: supported (SFF-8431 / SFF-8472 compatible management functions)

How to use

Insert the SFP28 transceiver into a compatible SFP28 slot on a switch, router or server until it clicks into place. Connect an appropriate single-mode LC duplex fiber cable, observing correct transmit/receive orientation. The module supports hot-plug operation, so it can be installed or removed while the host device is powered, but standard safety and handling procedures for electrostatic-sensitive devices should be followed. Configure the host port for 25G Ethernet as required by network policies and verify link status and diagnostic parameters via the device management interface.

Recommendations

Use certified single-mode fiber and LC duplex patch cords with proper end-face condition to achieve the specified reach. Monitor digital diagnostic values to detect issues such as excessive optical loss or temperature deviations. Ensure firmware and transceiver compatibility with the host equipment to avoid link negotiation problems.
