SFP28 transceiver CBO SFP28-25G-LR-NK-BO 25 Gbps single-mode LC up to 10,000 m

CBO SFP28-25G-LR-NK-BO is a compact SFP28 optical transceiver designed to support 25 Gbps links over single-mode fiber with an LC connector. The module enables long-distance 25G connectivity up to 10,000 meters, making it suitable for high-speed network links in data centers, central offices and campus backbones. The transceiver is intended for use in systems that require small form-factor pluggable optics and reliable single-mode performance for aggregation and metro applications.

Advantages

The transceiver offers a 25 Gbps data rate with single-mode transmission and an LC interface, combining high bandwidth with a compact pluggable form factor. Its reach of up to 10,000 meters provides flexibility for long-haul links without additional amplification. The module is optimized for interoperability with standard SFP28 ports and supports integration into switches, routers and servers that accept SFP28 optics.

Suitable for

• 25G backbone and aggregation connections between switches
• Long-distance server-to-switch links within campus or metro networks
• Data center uplinks where single-mode optics and LC connectors are required
• Edge and central office installations requiring compact pluggable 25G modules

Key specifications

• Data rate: 25 Gbps
• Fiber type: single-mode
• Connector: LC duplex
• Maximum reach: up to 10,000 meters
• Form factor: SFP28 (small form-factor pluggable 28)
• Application: long-reach 25G links for networking equipment

How to use

Install the SFP28 module into a compatible SFP28 slot on a switch, router or server following the host equipment vendor's hot-plug instructions. Ensure single-mode fiber cables with LC connectors are properly cleaned and connected to the module. Configure the network port on the host device for 25G operation as required by your network design and verify link status and diagnostics through the management interface.

Recommendations

Use single-mode fiber rated for the intended distance and verify connector cleanliness before insertion. Match transceiver specifications with the remote endpoint to ensure compatibility and reliable link performance. Monitor optical power and link diagnostics through the host device to detect and address any signal or alignment issues promptly.
