Do Q112-400G-DR4H and OSFP-400G-DR4H use the same modulation method?

Yes, they are the same. Both have 4x100G PAM4 modulation on the optical and electrical sides, and they are both flat-top modules used on the NIC side. Therefore, they are similar in terms of usage, and both can be connected to OSFP-800G-2xDR4H optical modules.

Description

NVIDIA/Mellanox® MMS1X00-NS400 Compatible 400G DR4 InfiniBand NDR Optical Transceiver Module (Single-port QSFP112, 1310nm, 100m, Single MPO-12/APC, DOM, for SMF, Flat Top )

NADDOD Q112-400G-DR4H is an InfiniBand and Ethernet 400Gb/s, Single-port, QSFP112, DR4 single mode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Data Center Reach 4-channel (DR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 100-meters. The QSFP112 shell has a flat-top and utilizes the riding heat sink (cooling fins) on the ConnectX-7 or BlueField-3 connector cage.

Questions & Answers

Ask a Question

What is the primary connectivity solution for Q112-400G-DR4H?

Q112-400G-DR4H is primarily used with ConnectX-7 or BlueField-3 DPU NICs with QSFP112 ports. On the opposite end, it is connected to OSFP-800G-2xDR4H optical modules on QM9700/9790 switches.

Can this 400G module operate at 200G? Is any additional configuration required?

Yes. The Q112-400G-DR4H module supports 200G operation without requiring any additional configuration.

Can the Q112-400G-DR4H module be used on an OSFP port NIC?

OSFP and QSFP112 are two completely different form factors, and QSFP112 cannot be adapted to OSFP ports.
