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

CBO SFP28-25G-ESR-QL-BO is an SFP28 optical transceiver module designed for 25 Gbit/s Ethernet links. The module features an LC duplex connector and supports a short-reach fiber link up to 300 meters. Its hot-pluggable SFP28 form factor allows straightforward insertion into compatible switch or server ports, enabling high-speed connectivity in data center, aggregation and access networks without requiring system downtime for installation.

Advantages

The transceiver delivers 25 Gbit/s line rate with low power consumption and stable optical performance for short-reach applications. Its LC duplex interface provides compatibility with standard multimode fiber cabling and passive fiber patching. The hot-pluggable design and compact SFP28 form factor simplify upgrades and replacements while minimizing disruption to existing hardware. The module is suitable for high-density installations where space and port density matter.

Suitable for

• 25G Ethernet links between switches and servers
• Short-reach connections in data center access and aggregation layers
• High-density server and switch installations using LC duplex multimode fiber

Key specifications

• Nominal data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 meters over multimode fiber (MMF)
• Form factor: SFP28, hot-pluggable
• Application: 25G Ethernet short-reach links
• Operating environment: designed for networking equipment racks and data center use

How to use

Install the SFP28 transceiver into a compatible SFP28 port on a switch or server while the host supports 25G operation. Connect LC duplex fiber patch cords to the module and ensure correct polarity. After insertion, verify the host port status and link activity through the switch or server management interface. For replacement, power-down is generally not required due to the hot-pluggable design; follow standard ESD precautions and vendor guidelines when handling the module.

Usage recommendations

Use multimode fiber cabling that meets the specified reach and attenuation requirements and keep connector end-faces clean to maintain optical performance. Verify compatibility with the host device's supported transceiver list and firmware. For optimal results in data center environments, route fiber to minimize bends and avoid tight radii.
