The NS-QSFP112‑400G‑SR4 is a high-density optical transceiver optimized for 400 Gigabit Ethernet and InfiniBand HDR connectivity. It delivers up to 425 Gbps (4×106.25 Gbps PAM4 lanes) over multimode fiber (MMF) using a single MPO‑12 interface at 850 nm.
Designed for data centers, it supports link lengths up to 70 m on OM3 and 100 m on OM4 fiber, and offers hot-pluggable installation and Digital Diagnostic Monitoring (DDM/DOM).
This module ensures broad compatibility with networking equipment from major brands such as Cisco, Juniper, Arista, HPE Aruba, Dell, Huawei, and others.
The NS-QSFP112-400G-SR4 is universally compatible across all brands. If you need to verify compatibility with your specific switch model, please click Contact Us Now for assistance.
Built to conform with 400GBASE‑SR4 (IEEE 802.3bs) and QSFP112 MSA standards, the module integrates a VCSEL laser array and PIN photodiode receiver per lane. It supports FEC (Forward Error Correction), includes onboard DSP with clock/data recovery, and maintains power consumption under 9 W. It functions reliably within a commercial operating range of 0 °C to 70 °C. It can also support 200G breakout operation when used in 2‑channel mode.
