Product information

Description

CBO 845398-B21 is a 25 Gbps SFP28 fiber optic transceiver designed for short-range multimode links. The module supports transmission over OM3 and OM4 multimode fiber with a maximum reach of up to 100 meters, and it fits standard hot-pluggable SFP28 ports used in 25 Gigabit Ethernet switches, routers and server network interfaces. The compact form factor enables high-density deployments in data center top-of-rack, aggregation and access-layer equipment while maintaining low power consumption and straightforward field replacement.

Advantages

The transceiver offers a reliable 25 Gbit/s data rate with multimode fiber compatibility for OM3 and OM4, ensuring interoperability with common data center cabling. Its hot-pluggable SFP28 form factor simplifies installation and maintenance without powering down equipment. The design emphasizes short-range performance up to 100 m, making it suitable for typical rack-to-rack connections while providing stable optical characteristics and compatibility with existing 25G infrastructure.

Suitable for

  • Short-range 25 Gigabit Ethernet connections in data centers
  • Rack-to-rack and within-rack multimode fiber links
  • Aggregation switches, top-of-rack switches and server NIC interfaces
  • Environments using OM3 or OM4 multimode cabling

Key specifications

  • Interface: SFP28 hot-pluggable module
  • Data rate: 25 Gbit/s
  • Fiber type: Multimode (OM3 / OM4)
  • Maximum reach: Up to 100 meters over OM3/OM4
  • Duplex: LC connector, duplex multimode link
  • Typical power consumption: optimized for low power in high-density applications
  • Application: 25 Gigabit Ethernet networking

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, router or server NIC while the host device is powered on; the hot-pluggable design allows insertion and removal without shutting down equipment. Connect duplex multimode fiber using LC connectors and ensure fiber polarity is correct. Verify link status through the host device management interface and confirm that the port is configured for 25 Gbit/s operation. For best results, use OM3 or OM4 multimode patch cords and maintain clean connector endfaces to avoid signal loss.

Usage recommendations

Use this transceiver in short-range multimode installations where 25 Gbit/s performance is required. Keep fiber connectors clean and use proper dust caps when not connected. Match the transceiver to the host port's supported speeds and optical type, and verify compatibility with the networking equipment vendor if specific interoperability lists are required.
