CBO SFP28 407-BBWK 25 Gbps 850 nm multimode optical transceiver

The CBO SFP28 407-BBWK 25 Gbps 850 nm multimode optical transceiver is a compact hot-pluggable module designed for short-reach 25 Gbit/s links over multimode fiber. Intended for use in data center and enterprise network equipment, it fits SFP28 ports and supports migration to 25G server, switch and storage interconnects while reducing cabling complexity for short-distance connections.

Advantages

This SFP28 transceiver provides a small form factor compatible with standard SFP28 slots and supports a 25 Gbit/s data rate at an 850 nm wavelength optimized for multimode fiber. The module is hot-pluggable, allowing quick replacement or upgrades without disrupting system operation. Its straightforward interface and short-reach focus simplify deployment in dense rack environments and enable scalable upgrades from lower data rates.

Suitable for

• 25G links between servers and top-of-rack switches over multimode fiber
• Short-reach connections inside data centers and equipment rooms
• Upgrading existing SFP28-capable network ports to 25 Gbit/s
• High-density switch fabrics and storage interconnects requiring compact transceivers

Key specifications

• Form factor: SFP28 (small form-factor pluggable)
• Data rate: 25 Gbit/s
• Wavelength: 850 nm
• Fiber type: multimode fiber (MMF)
• Reach: designed for short-reach links (data center/within-rack distances)
• Interface: hot-pluggable electrical and optical connector compatible with SFP28 ports

How to use

Insert the module into an SFP28-compatible port on a switch, server NIC or storage device until it seats and the retention mechanism engages. Ensure the connected multimode fiber patch cable has the correct connector type and polarity for the equipment in use, and that optical connectors are clean before mating. After installation, verify link status and speed through the host device management interface and monitor optical signal levels as required.

Recommendations

Use multimode fiber patch cords and MPO/LC connectors recommended by your system vendor and maintain clean connector endfaces. For short-reach 25G links, prioritize proper fiber type, connector cleanliness and adherence to port compatibility to ensure reliable operation.
