Transceiver module CBO QSFP+ SR4-BO 40 Gbps 850 nm multimode

The CBO QSFP+ SR4-BO 40 Gbps 850 nm multimode transceiver module is a compact optical interface designed for short-reach multimode fiber links in data center and enterprise networks. It provides 40 Gbps aggregate bandwidth via a QSFP+ form factor and operates at a nominal wavelength of 850 nm. The module is intended for high-density ports and aggregation applications where reliable, low-latency connectivity and straightforward installation are required.

Advantages

The module supports 40 Gbps throughput in a single QSFP+ package, enabling consolidation of multiple 10 Gbps lanes into a single physical port. Its 850 nm multimode design is compatible with MPO/MTP cabling systems commonly used in short-range data center topologies. The compact QSFP+ form factor reduces rack space requirements and facilitates hot-pluggable installation without interrupting adjacent interfaces.

How to use

Install the transceiver into a compatible QSFP+ port by aligning the module with the port slot and pressing gently until it latches. Connect an appropriate MPO/MTP multimode fiber cable with matching LC/MPO termination on the opposite ends or patch panels as required by the network design. Verify link status using the switch or host diagnostics, and monitor optical parameters through supported management interfaces where available. Remove the module by disengaging the latch and pulling straight out; handle connectors and fiber ends carefully to avoid contamination or damage.

Recommendations

Use multimode fiber with the recommended core size (e.g., OM3/OM4) for predictable link performance and follow data center cabling standards. Keep optical connectors clean and capped when not in use. Confirm compatibility with the target equipment's QSFP+ ports and firmware requirements before deployment.
