CBO QSFP28-100G-SR4-DE-BO transceptor QSFP28 100G SR4 850 nm fibra multimodo

QSFP28 CBO QSFP28-100G-SR4-DE-BO is a 100 Gbit/s short-reach multimode fiber transceiver operating at 850 nm. It implements the SR4 standard with four parallel optical lanes to deliver 100G connectivity over multimode fiber links. The module is intended for use in high-density data center environments and switch-to-switch connections where short-reach, high-bandwidth links are required.

Advantages

The transceiver offers 100 Gbit/s aggregate bandwidth through four 25 Gbit/s lanes, enabling straightforward upgrade paths for existing QSFP28 ports. Its operation at 850 nm is optimized for multimode fiber, providing compatibility with established OM3/OM4 cabling plants. The compact QSFP28 form factor allows for high port density on switches and routers while supporting hot-plug replacement for minimal service disruption.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or server adapter, ensuring the module is fully seated and latched according to the host device instructions. Connect appropriate multimode MPO/MTP patch cords to the module and route them following data center cable management best practices. Verify link status and speed through the host device management interface and ensure the remote end uses a matching SR4-compatible transceiver and multimode fiber type.

Recommendations

Use OM3 or OM4 multimode fiber to achieve nominal SR4 short-reach distances and maintain correct polarity and MPO/MTP connector orientation. Observe electrostatic discharge (ESD) precautions when handling the module and protect optical connector endfaces from contamination by using dust caps when not connected.
