What kind of cable fits into MMA1T00-HS (HDR QSFP56 MMF Transceiver)


we need a 200Gb Infiniband connection over about 90m and want to use existing OM4 fibers and HDR QSFP56 MMF Transceivers.

I think, we need MPO-12 polarity type B, where fibers 1 and 12, 2 and 11 and so on have to be connected (RX-TX).

Is it correct both cable ends must have two guide pins mating with two holes inside the transceiver (cable with male MPO connector) in contrast with Ethernet-MPO transceivers, which use female MPO connector cables?
