Which model should be used for a 400G OSFP port versus a 400G QSFP-DD port?

Use O400-2Q200-A for a finned-top OSFP port and Q400-2Q200-A for a QSFP-DD port. Both models terminate in two 200G QSFP56 branch interfaces and are available in lengths from 1m to 50m.

How does the 400G OSFP & QSFP-DD Breakout AOC category divide one 400G connection at the cable level?

It provides two independent 200G QSFP56 branches. Each cable has one 400G main interface and two fixed 200G branch interfaces, creating a 1-to-2 active optical breakout connection.

Can the two QSFP56 branches on O400-2Q200-A or Q400-2Q200-A connect to two different 200G endpoints?

Yes. Each QSFP56 branch carries an independent 200G connection and can terminate on a separate compatible 200G port, provided the 400G host port supports 2×200G breakout operation.

What cable lengths are available for O400-2Q200-A and Q400-2Q200-A?

1m to 50m for both models. The selected length applies to the complete cable assembly from the single 400G main end to the two 200G QSFP56 branch ends.

Do O400-2Q200-A and Q400-2Q200-A require separate optical transceivers or fiber patch cords?

No. Both models are integrated active optical cable assemblies with fixed pluggable interfaces at the 400G and 200G ends, so separate optical transceivers and external fiber patch cords are not required.

What host-port configuration is required before installing O400-2Q200-A or Q400-2Q200-A?

A 2×200G breakout mode is required on the 400G host port. The two remote interfaces must operate as 200G QSFP56 ports, consistent with the listed IEEE 802.3cd Ethernet support.

Does the finned-top OSFP interface on O400-2Q200-A increase the branch rate compared with Q400-2Q200-A?

No. The finned top is part of the OSFP interface’s mechanical and thermal design. It does not change the breakout structure, as both models provide two 200G QSFP56 branches.

What device information should be provided when asking AICPLIGHT to check O400-2Q200-A or Q400-2Q200-A compatibility?

Provide the 400G device model, host-port form factor, supported 2×200G breakout mode, both 200G endpoint models, and the required length from 1m to 50m. This information allows the appropriate cable configuration to be checked before ordering.

400G OSFP & QSFP-DD Breakout AOC Overview

The 400G OSFP & QSFP-DD Breakout AOC category contains two active optical breakout cables for cloud computing, supercomputing, and high-density rack environments. Each model divides one 400G main interface into two 200G QSFP56 branches. The series includes finned-top OSFP and QSFP-DD main-end configurations and complies with IEEE 802.3cd, OSFP Rev. 5.0, SFF-8679, SFF-8661, SFF-8636, and CMIS Rev. 4.0.

O400-2Q200-A is an active optical breakout cable connecting one 400G finned-top OSFP interface to two 200G QSFP56 branch interfaces. The 400G main link is divided into two independent 200G optical connections for linking an OSFP-equipped device with two QSFP56 ports.

Q400-2Q200-A is an active optical breakout cable that divides one 400G QSFP-DD interface into two 200G QSFP56 branches. Each branch carries 200G, supporting direct optical connections between a QSFP-DD-equipped device and two QSFP56-equipped ports in cloud and supercomputing systems.
