## Long description

The CBO QSFP28 100 Gbit/s optical transceiver with a fixed 3 m cable from the BlueOptics series is a compact QSFP28 form-factor module designed for 100 G Ethernet and data center interconnects. The unit integrates a pre-terminated 3 m cable to provide a direct optical link for short-reach connections, reducing the need for additional patch cords and simplifying deployment in rack and spine-top-of-rack environments.
Advantages
This optical transceiver delivers 100 Gbit/s line-rate performance in a QSFP28 package while offering the convenience of an attached 3 m fiber cable for immediate connection. Its compact design supports high-density switch and router ports and helps reduce cable management complexity. The product is compatible with standard 100 G Ethernet environments and is intended for use in typical data center and enterprise networking setups where reliable short-reach links are required.
Suitable for
Short-reach 100 G Ethernet links within racks or between adjacent racks
Data center aggregation and spine-leaf interconnects
High-density switch and router ports where a fixed cable simplifies patching
Upgrading or expanding 100 G connections without adding external patch cords
Key specifications
Interface: QSFP28 form factor supporting 100 Gbit/s operation
Cable: Fixed 3 m optical cable integrated with the transceiver
Application: Short-reach 100 G Ethernet and data center interconnects
Use environment: Designed for use in rack, top-of-rack and spine switch installations
Compatibility: Intended for standard 100 G networking equipment that accepts QSFP28 modules
How to use
Install the QSFP28 transceiver into a compatible QSFP28 slot on the switch or router until it seats firmly and the retention mechanism engages. Route the integrated 3 m cable to the mating transceiver or patch point, taking care to avoid sharp bends and excessive tension on the fiber. Verify link status via the host equipment interface and monitor for proper optics diagnostics if supported by the switch. For removal, disengage the retention mechanism and pull the module straight out, handling the fiber connector to avoid contamination.
Usage recommendations
Ensure both ends of the optical link use compatible QSFP28 100 G modules or adapters and maintain appropriate bend radius and cleanliness of fiber connectors. Use equipment vendor guidance for supported transceiver types and firmware compatibility to avoid interoperability issues.
