SFP28 module CBO SFP28-25G-ESR-CI-BO 25 Gbit/s LC 300 m

This CBO SFP28-25G-ESR-CI-BO 25 Gbit/s LC optical transceiver is designed for short-reach fiber links in data centers, enterprise networks and high-performance communications equipment. The module fits standard SFP28 ports and provides a 25 Gigabit Ethernet physical interface over single-mode or specified multimode fiber with an operational reach up to 300 meters. Compact and hot-pluggable, it supports low-latency, high-throughput connections between switches, routers and servers where reliable 25 Gbit/s links are required.

Advantages

The transceiver offers 25 Gbit/s data throughput in a small form factor compatible with SFP28 ports, enabling straightforward upgrades from 10G to 25G infrastructure. Its LC duplex connector ensures broad compatibility with common fiber patching and cabling systems. Built for short-reach deployments, the module balances performance and power consumption for dense rack installations while maintaining signal integrity for high-speed packet transmission.

Suitable for

• 25 Gigabit Ethernet uplinks between switches and aggregation devices
• Server-to-switch connections in data center racks
• Short-reach fiber links inside enterprise campuses and campus buildings
• High-density networking environments requiring hot-pluggable transceivers

Key specifications

• Nominal data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 m (dependent on fiber type and link conditions)
• Form factor: SFP28 (hot-pluggable)
• Intended application: 25 Gigabit Ethernet short-reach optical links

How to use

Insert the module into a compatible SFP28 port on a switch, router or server with the device powered according to the equipment vendor’s guidelines. Connect LC duplex fiber patch cords following the correct polarity and ensure fiber type and transceiver reach are suitable for the planned link. After insertion, verify link status and speed through the host device management interface and perform any required firmware or configuration steps for the 25 Gbit/s interface.

Recommendations

Use certified LC patch cords and check fiber cleanliness before connection to avoid signal loss. Verify compatibility with the host equipment’s supported transceiver list and observe manufacturer guidelines for operating temperature and power budgets to ensure stable 25 Gbit/s operation.
