Módulo SFP28 de fibra ótica CBO SFP28-25G-LR-LO-BO 25 Gbit/s LC monomodo 10 km

CBO SFP28-25G-LR-LO-BO is a fiber optic SFP28 transceiver module that delivers a 25 Gbit/s data rate over single-mode fiber using an LC duplex connector. Engineered for 25G Ethernet links, this module supports long-reach connections up to 10,000 meters, enabling reliable high-speed links between switches, servers and transport equipment in data centers and carrier networks. The module is intended for environments that require stable, low-error, long-distance 25 Gbps optical connectivity.

Advantages

The module provides a compact SFP28 form factor that fits standard 25G ports and supports high-density deployments. Its single-mode design and LC interface offer compatibility with common fiber infrastructures while minimizing insertion loss. With a rated reach of up to 10 km, it enables extended link distances without intermediate amplification or regeneration, reducing equipment complexity. The transceiver is designed for interoperability with 25G Ethernet equipment and for use in network topologies that demand consistent throughput and low latency.

Suitable for

• 25G Ethernet uplinks between switches and aggregation devices
• Long-distance server-to-switch connections within campus or metro networks
• Carrier and service provider transport links requiring 10 km reach
• Data center spine-leaf architectures with high-density port requirements

Key specifications

• Optical interface: LC duplex connector
• Fiber type: single-mode fiber (SMF)
• Data rate: 25 Gbit/s
• Maximum reach: up to 10,000 meters (10 km)
• Form factor: SFP28
• Typical application: 25G Ethernet and high-speed optical links

How to use

Install the module into a compatible SFP28 port on your switch, router or host adapter until it clicks into place. Connect single-mode LC duplex patch cables between the module and the remote optical equipment, observing correct transmit/receive orientation. Ensure that connected devices are configured for 25G operation and that fiber attenuation and connector cleanliness meet link budget requirements. Monitor link status via the host device to verify synchronization and error-free operation.

Recommendations

Before installation, inspect and clean LC connectors with appropriate fiber cleaning tools to prevent signal loss. Verify transceiver compatibility with the network equipment vendor and confirm that fiber attenuation and dispersion are within acceptable limits for 10 km links. Use labeled and tested single-mode patch cords and perform post-installation link tests (optical power, BER or loopback checks) to ensure expected performance.
