SFP28 transceiver CBO SFP28-25G-ESR-JU-BO 25 Gbit/s LC 300 m

CBO SFP28-25G-ESR-JU-BO is an SFP28 optical transceiver module that supports data rates up to 25 Gbit/s and uses a duplex LC connector. Designed for 25G Ethernet environments, the module provides hot-pluggable connectivity for network devices such as switches, routers and servers. With an optical reach of up to 300 metres over multimode fibre, it is intended for short-reach links in data centres and enterprise networks that require compact, high-speed fibre connections.

Advantages

The transceiver offers 25 Gbit/s transmission in an industry-standard SFP28 form factor, enabling high-density port configurations and straightforward integration into existing hardware. Its hot-pluggable design allows replacements or upgrades without powering down the host device. The LC duplex connector and multimode compatibility simplify cabling in rack and patch-panel installations, while the specified reach up to 300 m covers typical intra-rack and inter-rack connections in data centre and campus environments.

Suitable for

• 25G Ethernet connections between switches and leaf/spine fabrics
• Short-reach server-to-switch links in data centres
• Enterprise aggregation and distribution layer uplinks
• High-density optical port deployments where space and power are constrained

Key specifications

• Form factor: SFP28 (25 Gbit/s class)
• Maximum data rate: 25 Gbit/s
• Connector type: duplex LC
• Optical reach: up to 300 metres over multimode fibre
• Compatibility: designed for 25G Ethernet applications
• Hot-pluggable for live replacement and maintenance

How to use

Insert the SFP28 transceiver into a compatible SFP28-capable port on a switch, router or server until it clicks into place. Connect a matching duplex LC multimode fibre cable between transceivers on both ends of the link, ensuring correct polarity. The host device should automatically detect the module; verify link status and speed through the network device management interface. To remove, disengage any retention mechanisms and gently pull the module from the port.

Recommendations

Use multimode fibre cabling rated for the intended distance and ensure clean LC connectors to maintain optical performance. Verify host compatibility for SFP28 modules and apply any vendor-specific settings required for 25G operation. Handle the transceiver with ESD precautions and keep protective caps on the optical interfaces when not in use.
