SFP28 transceiver CBO SFP28-25G-LR-CN-BO 25 Gbit/s LC up to 10000 m

The CBO SFP28-25G-LR-CN-BO is a single‑mode optical SFP28 transceiver module that supports 25 Gbit/s data transmission over LC duplex interfaces. Designed for long-reach links, this module provides hot‑pluggable connectivity suitable for switches, routers and servers in data center and telecom environments. It enables high‑speed uplinks and interconnects with a reach of up to 10,000 meters using single‑mode fiber.

Advantages

This SFP28 transceiver offers a compact form factor compatible with SFP28 ports, enabling easy installation and replacement without powering down network equipment. It supports 25 Gbit/s line rates and uses an LC duplex optical connector for stable single‑mode links. The module is designed for long‑reach applications, providing reliable optical performance over distances up to 10 km and supporting common network interoperability requirements.

Suitable for

• 25 Gbit/s uplinks between switches and aggregation devices
• Long‑reach single‑mode connections in data centers and campus networks
• Server to switch interconnects requiring high bandwidth
• Metro and carrier access links over single‑mode fiber

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: single‑mode fiber
• Connector: LC duplex
• Maximum reach: up to 10,000 m (10 km)
• Form factor: SFP28 (hot‑pluggable)
• Application: long‑reach optical link for networking equipment

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on the switch, router or server until it clicks into place. Connect LC duplex single‑mode fiber patch cables ensuring correct polarity and secure connectors. Verify link status and interface configuration on the network device; configure the port for 25 Gbit/s operation if required by the host. When removing the module, power down or disable the port according to equipment guidelines if hot‑swap is not supported, then disengage the transceiver by releasing the latch and carefully withdrawing the module.

Recommendations

Install in clean environments and use dust caps on the LC connectors when the module is not in use. Ensure fiber connectors are inspected and cleaned before mating. Match fiber type and transceiver specifications for distance and wavelength to avoid signal degradation. Follow vendor documentation for compatibility and interface settings to guarantee stable 25 Gbit/s operation.
