SFP28 Optical Transceiver CBO AFBR-8CER07Z 100G SR4 up to 30 m

The SFP28 Optical Transceiver CBO AFBR-8CER07Z 100G SR4 up to 30 m is a compact pluggable module designed for short-reach 100 Gigabit Ethernet links over multimode fiber. It provides high-density, low-latency connectivity for data centre environments and networking equipment with SFP28 ports. The module supports SR4 operation to connect top-of-rack switches, aggregation switches and servers within rack or adjacent rack deployments over distances up to 30 metres using appropriate multimode fiber cabling.

Advantages

This SFP28 optical transceiver offers a compact form factor for space-constrained racks and supports hot-swap installation to minimise downtime. It is engineered for short-reach links with low latency and stable signal integrity, enabling reliable 100G transmission in high-density environments. The module is compatible with standard SFP28 cages and supports the SR4 multimode interface, which simplifies cabling and reduces infrastructure complexity in data centre deployments.

Suitable for

• Top-of-rack and leaf-spine switching in data centres
• Server-to-switch 100G interconnects within racks
• High-density aggregation links in campus or enterprise networks
• Short-reach multimode fibre connections up to 30 m

Key specifications

• Data rate: 100 Gigabit Ethernet (100G)
• Form factor: SFP28 compact pluggable transceiver
• Optical interface: SR4 multimode
• Maximum reach: up to 30 metres over multimode fibre
• Typical use: short-reach intra-rack and adjacent-rack links
• Hot-pluggable for live replacement and maintenance

How to use

Insert the SFP28 transceiver into an SFP28-compatible port on a switch or server until it seats securely; avoid excessive force. Connect the appropriate SR4 multimode fibre cable assembly, ensuring correct polarity and connector type for the equipment in use. After physical installation, verify link status through the host device management interface and confirm the port operates at 100G. For hot-swap replacement, power down is not required on most systems — follow the host vendor guidelines for safe insertion and removal.

Usage recommendations

Use OM3 or OM4 multimode fibre and SR4-compliant cabling assemblies to achieve reliable performance up to 30 metres. Maintain clean connector end-faces and follow ESD precautions during handling. Check compatibility notes for the host equipment and update transceiver firmware or device drivers if required by the switch or server vendor.
