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

The SFP28 optical transceiver CBO SFP28-25G-LR-IB-BO is a single-port module that supports 25 Gbit/s data transmission over single-mode fiber with an LC duplex connector. Engineered for long-reach links up to 10,000 m, this transceiver is intended for use in data center uplinks, enterprise switches and routers, and carrier network environments. The module provides interoperable optical connectivity for 25G Ethernet applications and allows a straightforward upgrade path from 10G links while maintaining compact SFP28 form factor compatibility.

Advantages

The transceiver delivers a 25 Gbit/s data rate and long-reach performance, enabling extended-distance connectivity without intermediate amplification. Its LC duplex interface ensures compatibility with common single-mode fiber cabling systems. The small SFP28 form factor reduces slot space requirements and simplifies integration into existing switch and router platforms. The design emphasizes interoperability with standard 25G Ethernet equipment and consistent optical performance across supported distances.

Suitable for

• Data center uplinks between aggregation and core switches
• Enterprise switch-to-switch or switch-to-router long-distance links
• Carrier and metro network interconnects requiring 25G bandwidth
• Upgrading existing 10G links to 25G while reusing single-mode fiber plant

Key specifications

• Data rate: 25 Gbit/s
• Connector type: LC duplex
• Optical reach: up to 10,000 m over single-mode fiber
• Form factor: SFP28
• Application: 25G Ethernet
• Fiber type: single-mode

How to use

Install the SFP28 transceiver into a compatible SFP28 slot on a switch, router or transceiver-capable device, ensuring the module clicks into place. Connect LC duplex single-mode fiber patch cords observing correct transmit/receive orientation. After insertion, verify link status and speed through the host device management interface and confirm optical parameters such as receive signal strength. Follow device-specific guidance for hot-swap handling if replacing modules in live systems.

Recommendations

Use certified single-mode LC duplex fiber cabling and ensure connectors are clean before mating to maintain signal integrity. For long spans approaching the maximum reach, verify end-to-end optical power budget and consider margin for connectors and splices. Ensure host equipment firmware supports SFP28 25G modules to guarantee interoperability.
