SFP28 transceiver CBO SFP28-25G-LR-MA-BO 25 Gbit/s LC single‑mode up to 10,000 m

CBO SFP28-25G-LR-MA-BO is an SFP28 optical transceiver module that supports a 25 Gbit/s data rate over single‑mode fiber. Equipped with an LC duplex connector and designed for long‑reach links, it enables optical connections up to 10,000 m without intermediate signal conversion. This module is suitable for integration into switches, routers and servers to provide 25 Gigabit Ethernet uplink or downlink connectivity in data centers and carrier networks.

Advantages

The transceiver delivers a native 25 Gbit/s serial interface with single‑mode optics, offering extended reach up to 10 km while maintaining a compact SFP28 form factor. Its LC connector ensures compatibility with standard single‑mode patching and fiber cabling. The module is designed to provide stable optical performance for uplink/downlink applications, reducing the need for additional amplification or regeneration equipment on long fiber runs.

Suitable for

• 25 Gigabit Ethernet uplinks in data center top-of-rack and spine switches
• Interconnects between routers and aggregation switches
• Server network interfaces requiring 25 Gbit/s optical links
• Carrier and metro fiber links where single‑mode reach up to 10 km is required

Key specifications

• Form factor: SFP28 (small form-factor pluggable 28)
• Data rate: 25 Gbit/s serial
• Fiber type: single‑mode
• Connector: LC duplex
• Maximum reach: up to 10,000 m (10 km)
• Optical interface: long‑reach (LR) optics

How to use

Insert the SFP28 module into a compatible SFP28 slot on a switch, router or server until it latches. Connect the LC duplex single‑mode fiber patch cable, verifying transmit and receive polarity. Ensure the host device is configured for a 25 Gbit/s link and check link status via the device management interface. Monitor optical levels and link quality to confirm stable operation; replace or reseat the module if the link does not establish. Follow proper ESD handling and clean fiber connectors before mating to avoid signal loss.

Recommendations

For reliable long‑reach operation, use single‑mode fiber with appropriate attenuation and test end-to-end loss to confirm it is within the module's operating range. Keep LC connectors clean, verify correct polarity, and use compatible equipment that supports SFP28 25 Gbit/s optics. Observe manufacturer guidelines for operating temperature and handling to maintain transceiver performance.
