200Gb/s QSFP28 Passive Copper Cable

This Mellanox LinkX cable delivers up to 200Gb/s data rates over QSFP28 ports for InfiniBand HDR systems. It operates without external power and meets SFF-8665 compliance with a BER better than 10-15. RoHS compliant and halogen free, it is rated for 0-70°C case temperatures.

Data centre short-reach interconnects

Suitable for rack-to-rack or intra-rack links where passive copper reaches the required distance. Not for buyers who need longer reach than passive copper supports or who require active optical cables for extended runs.

Passive copper reach limit

The cable length determines whether the 200Gb/s signal meets the BER target without amplification; verify the maximum supported distance for your specific switch and HCA ports before purchasing.

Questions about this item

What does the SFF-8665 QSFP28 interface cap in practice?

The QSFP28 connector follows the SFF-8665 specification and supports up to 200Gb/s data rates for IBTA IB HDR links.

What clearance does the passive copper cable need to fit?

The QSFP28 plugs insert into standard cages; allow enough depth for the latch to engage and a bend radius that avoids kinking the copper twin-ax.

How is the cable installed and what step is often missed?

Push each QSFP28 end straight into the port until the latch clicks, then verify the link light; skipping the audible click leaves the connection unseated.
