CBO InfiniBand-kaapeli CBL-QSFP-40GE-PASS-1M-F1-BL — QSFP-läpivienti, 1 m, musta

The CBO InfiniBand cable CBL-QSFP-40GE-PASS-1M-F1-BL is a 1-metre passive QSFP pass-through cable designed for short-reach, high-speed interconnects. Manufactured under the BlueOptics brand, this black cable provides a direct QSFP connection suited to 40 Gigabit Ethernet passthrough applications in data centre environments. Its compact one-metre length minimises excess cabling in rack-mounted installations while supporting bandwidth and signal integrity requirements typical for server-to-switch or switch-to-switch links.

Advantages

This passive QSFP cable offers a straightforward, low-power solution for establishing short distance 40GE links without active transceivers. Its slim, black jacket reduces clutter in dense rack environments and eases cable management. The fixed 1 m length is convenient for connecting neighbouring ports within the same rack or adjacent racks, delivering reliable electrical passthrough performance appropriate for InfiniBand and 40GE environments.

Key specifications

How to use

Identify the QSFP ports on the devices to be connected, ensuring both ports support passive QSFP passthrough and the required 40GE signalling. Align and insert the QSFP connectors into each port until they seat securely; follow device-specific release or latch procedures when removing the cable. Confirm link status and speed on connected equipment according to the switch or server interface indicators and management tools. Keep the cable routed to avoid sharp bends and to maintain appropriate bend radii for optimal signal integrity.

Recommendations

For best results, use this 1 m passive QSFP cable within the same rack or between adjacent racks to minimise attenuation and signal degradation. Avoid exceeding the recommended bend radius, keep the cable clear of power sources that may introduce interference, and verify compatibility with your QSFP ports and 40GE configuration before deployment.
