Fiber optic transceiver CBO PAN-QSFP-40GBASE-SR4 40 Gbit/s, multimode, up to 150 m

The Fiber optic transceiver CBO PAN-QSFP-40GBASE-SR4 40 Gbit/s, multimode, up to 150 m is a QSFP form-factor module designed for short-range, high-bandwidth links. It supports 40 Gbit/s aggregated throughput by combining four parallel multimode fiber channels (SR4). Engineered for data center top-of-rack connections, switch uplinks and server interconnects, the module provides a compact, hot-pluggable solution for dense networking environments and fast replacement cycles.

Advantages

The transceiver delivers 40 Gbit/s performance over multimode fiber with a reach of up to 150 m, enabling high-capacity links without the complexity of single-mode optics. Its QSFP form factor supports four-lane parallel transmission for efficient use of fiber infrastructure and reduced cabling. The plug-in design simplifies installation and maintenance, while industry-standard electrical and optical interfaces ensure broad compatibility with compatible switches and servers.

Suitable for

• Data center top-of-rack and leaf-spine connections
• Switch uplinks and aggregation links
• Server-to-switch high-speed interconnects
• Short-range multimode fiber backbone links within campus and enterprise environments

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbit/s aggregated (four parallel lanes)
• Transmission type: Multimode fiber, parallel SR4
• Maximum reach: Up to 150 meters on multimode fiber
• Optical interface: Four-channel parallel MPO/MTP connector compatibility
• Hot-pluggable: Yes
• Typical applications: Short-reach Ethernet, data center interconnects

How to use

Insert the QSFP transceiver into a compatible QSFP port on the switch or server with the module keyed to align the connector. Connect the multimode MPO/MTP fiber assembly, ensuring correct polarity and clean connector endfaces to maintain optical performance. After insertion, verify link status through the host device management interface and monitor optical parameters if supported. For removal, power down the port if required by the host and gently extract the module by the release mechanism.

Recommendations

Use multimode fiber cabling compliant with relevant standards (OM3/OM4) to achieve the specified reach. Inspect and clean MPO/MTP connectors before mating, avoid excessive bends near the module, and follow ambient temperature and handling guidelines provided by the host equipment vendor to ensure reliable operation.
