Product questions & answers

What is the branch form factor and speed?

Four QSFP112 branches each carry 200G with two 100G-PAM4 lanes. The head is twin-port OSFP with 800G aggregate capacity.

What hosts are described?

The manual describes QSFP112 ConnectX-7 adapters and BlueField-3 DPUs, paired with the appropriate Quantum-2 or Spectrum-4 switch configuration.

Is this an OSFP-tail cable?

No. These variants have QSFP112 tails. MCP7Y50 is the separate OSFP-tail family.

What lifecycle warning applies?

The exact 1 m, 2 m and 3 m OPNs are Last Time Buy in the cited 2026 firmware matrices. Confirm lifecycle and the required replacement path before choosing them for a new design.

Where does forward error correction take place?

The FAQ places FEC in the switch and network adapter. Match the supported endpoint configuration; a cable does not independently fix a FEC mismatch.

Why can a cable have two minimum bend radii?

The connector exit generally needs a larger bend radius than the cable body. Follow the exact assembly drawing and leave adequate space behind the rack door.
