Mellanox Technologies MFA1A00-E020 20m fibre optic cable

SKU CH-TRG1-DHQS5 MPN MFA1A00-E020

A 20 metre QSFP28 active optical cable rated for 100 Gbps InfiniBand EDR with a 7.5 mm minimum bend radius and OFNP jacket

  • 20-metre reach connects distant racks without signal loss
  • 100 Gbps bandwidth supports InfiniBand EDR workloads
  • QSFP28 connectors plug straight into compatible ports
  • VCSEL transmitter delivers reliable optical transmission
  • OFNP jacket meets plenum fire-safety requirements

20-metre QSFP28 active optical cable

This 20-metre active optical cable uses QSFP28 connectors and is rated for 100 Gbps InfiniBand EDR links. It suits data-centre racks and high-performance compute clusters that need low-latency connections over longer runs than copper allows.

Plug-and-play with a 7.5 mm bend limit

The cable arrives terminated and requires no field assembly; insert each QSFP28 end into a compatible port and the link trains automatically. Take care not to bend the fibre tighter than the 7.5 mm minimum radius, as tighter curves are the most common cause of signal loss or permanent damage.

100 Gbps over 20 metres with OFNP jacket

At 20 metres the cable comfortably carries the full 100 Gbps EDR rate, while the OFNP-rated jacket meets plenum fire-safety requirements for in-wall or raised-floor routing. Runs beyond 20 metres or speeds above 100 Gbps exceed the specified reach and would need a different solution.

Questions about this item

How can I verify the 100Gbps InfiniBand EDR link is active after connecting the QSFP28 cable?

Check the switch or HCA port LEDs for a solid link light and run an InfiniBand diagnostic such as ibdiagnet to confirm 100Gbps EDR operation without errors.

What comes with the 20m active optical cable and what must be purchased separately?

The cable ships with QSFP28 connectors on both ends; no transceivers are needed. You only need compatible QSFP28 ports on your switches or adapters.

Which length should I choose between the 15m and 20m versions for my rack layout?

Select the 15m cable for runs up to 15m (49ft) and the 20m cable for runs up to 20m; both support 100Gbps EDR with a 7.5mm minimum bend radius.
