Optical transceiver CBO SFP28-25G-ESR-CH-BO 25 Gbit/s SFP28, LC connector, 300 m reach

SFP28 CBO SFP28-25G-ESR-CH-BO is a 25 Gbit/s optical transceiver module in a compact SFP28 form factor with an LC duplex connector and a maximum reach of 300 meters over multimode fiber. It is intended for deployment in data center and enterprise networks where short-reach 25GbE links are required. The module is hot-pluggable and compatible with standard SFP28 ports, providing a space-efficient solution for uplinks, top-of-rack switches and server interconnects.

Advantages

The module offers reliable 25 Gbit/s data transmission over short-range multimode fiber and supports LC duplex connectivity in a small SFP28 package. Its hot-pluggable design simplifies installation and maintenance without powering down equipment. The 300 m reach covers common data center spans and consolidation cabling, while the standardized form factor ensures interoperability with many SFP28-enabled switches and servers.

Suitable for

• 25 Gigabit Ethernet uplinks between switches in rack and row topologies
• Server-to-switch interconnects in data center environments
• Short-range multimode fiber connections within enterprise campuses and wiring closets
• Switch stacking and aggregation ports requiring compact, high-speed transceivers

Key specifications

• Data rate: 25 Gbit/s
• Form factor: SFP28
• Connector: LC duplex
• Maximum reach: 300 meters over multimode fiber
• Wavelength range: short-range multimode (850 nm typical)
• Hot-pluggable: yes
• Application: 25 Gigabit Ethernet (25GbE)

How to use

Insert the SFP28 module into a compatible SFP28 port on your switch or server until it latches; ensure the host device is powered and supports 25GbE SFP28 optics. Connect LC duplex multimode fiber patch cords to the module’s connectors observing correct transmit/receive orientation. Monitor the link status via the host device management interface and verify traffic operation. To remove, release the latch mechanism and withdraw the module while avoiding excessive force.

Recommendations

Use multimode fiber of the appropriate grade (such as OM3/OM4) and tested patch cords to achieve the specified 300 m reach. Keep the optical interfaces capped when not connected and avoid exposure to dust. Refer to the switch or server vendor documentation for specific compatibility lists and any required firmware settings to ensure full interoperability.
