QSFP Passive Copper Cable

The Lenovo 46W0583 is a passive copper cable with QSFP connectors on both ends. It spans 6.56 ft and carries the FDR14 InfiniBand designation. The cable is supplied new and is intended for direct device-to-device links.

Suitable for short rack connections.

This cable suits builders linking switches, adapters or storage nodes within a single rack or adjacent racks. Buyers who need longer reach or active signal conditioning should look at other options because the fixed 6.56 ft length and passive design limit distance and flexibility.

FDR14 InfiniBand rating decides compatibility

The single specification that determines fit is the FDR14 InfiniBand rating combined with the QSFP connector pair. Only equipment that explicitly supports this signalling standard will operate correctly with the cable.

Questions about this item

What bandwidth does the QSFP FDR14 interface support on this 6.56 ft cable?

The QSFP FDR14 interface supports up to 14 Gbps per lane, giving 56 Gbps aggregate throughput over the 6.56 ft passive copper assembly.

What rack spacing and bend radius does the 6.56 ft QSFP passive copper cable require?

The 6.56 ft passive copper cable needs enough clearance for its fixed QSFP ends and a minimum bend radius of roughly five times the cable diameter to avoid signal degradation.

How do you correctly seat the QSFP connectors on this 6.56 ft cable, and what step is often missed?

Align each QSFP connector with the port, push straight in until the latch clicks, then verify the link LEDs; the step often missed is confirming the latch is fully engaged on both ends.
