Why is the module using an APC interface instead of a PC interface?

Optical signals are very sensitive to return loss. APC (8° angle) can significantly reduce reflection interference, enhancing link consistency and error tolerance.

Does it support separate configuration/use of the two SR4 channels?

Yes, it supports it. The module has two independent SR4 engines internally, allowing for separate connections to different device ports.

Which mainstream platforms is the module compatible with?

It can be adapted to Broadcom Tomahawk 5 platform, NVIDIA Spectrum-X switches, Arista 7060/7050X series, and others.

Description

Arista Compatible 400GBASE-2xSR4 PAM4 850nm 100m Dual MTP/MPO-12 APC MMF Finned Top Optical Transceiver Module

NADDOD Arista OSFP-400G-2xSR4 Compatible optical transceiver is an eight-channel, parallel, pluggable fiber-optic OSFP for 400 Gigabit Ethernet applications, featuring a finned-top design. It integrates eight data lanes in each direction at 8×26.5625 GBd. The OSFP 2xSR4 supports transmission lengths of up to 100 meters over OM4 multimode fiber (MMF).

The 400G OSFP 2xSR4 is intended for short-reach, high-bandwidth data communication and interconnect scenarios in modern data centers. This module is primarily used on OSFP switch ports, such as the N9500-64OC or Arista 7060X6-64PE, and connects to 200G QSFP56 NICs via 12-core multimode MPO patch cables (e.g., M4MPOA12FB), enabling interconnection between an 800G OSFP switch and 200G NICs.

Questions & Answers

Ask a Question

What is the application scenario for the OSFP-400G-2×SR4 module?

This module is primarily used on OSFP switch ports, such as the N9500-64OC or NVIDIA SN5600. It connects to 200G QSFP56 NICs on the other end via 12-core multimode MPO patch cables (e.g., M4MPOA12FB), enabling interconnection between an 800G OSFP switch and 200G NICs.

Can this module interoperate with 400G SR4 modules?

No, it cannot. This module has dual ports with 8×50G PAM4. Common 400G SR4 optical modules, such as OSFP-400G-SR4, Q112-400G-SR4, and QDD-400G-SR4, are all single-port modules with 4×100G PAM4. The per-channel modulation rates do not match, so they are not interoperable.

Can this module be used with a CX7 OSFP 400G NICs?

No, it cannot. This module uses a finned top design, intended for switch-side deployment. For NIC-side use, flat top optical modules are recommended, such as OSFP-400G-SR8 or OSFP-400G-SR4.
