CBO QSFP to QSFP Cable S26361-F3986-L402-BL 2 m, 40 Gbit/s

CBO QSFP to QSFP Cable S26361-F3986-L402-BL 2 m, 40 Gbit/s is a direct-attach passive copper cable designed to link QSFP ports on switches, servers and network appliances. With a 2 metre length and 40 Gbit/s rated bandwidth, this cable provides a compact, low-latency short-reach connection suitable for within-rack or rack-to-rack interconnects in data center and enterprise network environments. The cable implements the QSFP form factor on both ends for straightforward insertion into compatible QSFP cages and slots.

Advantages

The cable offers a simple plug-and-play solution with no additional transceivers or fiber required, reducing component count and power consumption. Passive copper construction delivers low latency and stable 40 Gbit/s throughput for short distances, while the standardized QSFP interface ensures broad compatibility with equipment supporting QSFP direct-attach copper links. The 2 m length balances reach and cable management for dense rack deployments.

Suitable for

• Short-reach interconnects between switches within a rack
• Rack-to-rack connections in adjacent cabinets
• High-bandwidth links between servers and top-of-rack or leaf switches
• Low-latency connections for clustered compute and storage nodes

Key specifications

• Connector type: QSFP to QSFP (quad small form-factor pluggable interfaces)
• Length: 2 metres
• Data rate: 40 Gbit/s aggregate
• Cable type: Passive copper direct-attach cable
• Typical use: Short-reach, within-rack or adjacent rack connections

How to use

Ensure both equipment QSFP ports support passive QSFP direct-attach copper links at 40 Gbit/s and that devices are powered off or follow hot-plug recommendations from the equipment vendor before insertion. Align the QSFP connector keyed housing with the port and insert until the retention mechanism engages. Verify link status on the connected devices and monitor for expected 40 Gbit/s operation. To remove, disengage the retention latch and pull the connector straight out, taking care not to bend or stress the cable near the connector ends.

Recommendations

Use this cable for short distances up to 2 m in high-density rack environments; avoid routing near sources of EMI and maintain bend radius specified by equipment vendors to preserve signal integrity and mechanical reliability.
