400G QSFP112 SR4 1310nm 50m MPO Optical Module

Product Overview

QSFP112-SR4-400G optical module (multimode, 850nm, 50m, MPO-12/APC, DOM)

The QSFP112-SR4-400G optical module is a 400Gb/s single-port QSFP112 optical module that utilizes SR4 multimode parallel transmission technology and is equipped with a single-channel 4-fiber MPO-12/APC fiber interface. The short-reach four-channel (SR4) design incorporates 100G-PAM4 modulation technology, achieving a maximum transmission distance of 50 meters when using OM4 multimode fiber.
The QSFP112 optical module can be utilized in QSFP112/QDD switches and Ethernet adapters. Characterized by low latency, low power consumption, and high reliability, it can be connected upstream to 800G Ethernet switches in the Spine-Leaf architecture, and can also interconnect with 400G QSFP-DD or OSFP SR4, catering to diverse application scenarios. When connecting a 1:2 optical splitter cable, the splitter end only has 2 channels, and the 400G optical module only activates 2 channels, automatically achieving a 200G rate and reducing power consumption.
This is an ideal solution for supercomputing, capable of seamlessly integrating into computing and storage infrastructure, ensuring efficient high-performance interconnectivity.
