QDD-400G-FR4-S Optical Transceiver Module

QDD-400G-FR4-S Optical Transceiver Module

The QDD-400G-FR4-S is an optical transceiver module designed for high-speed data transmission over fibre optic cables. Here’s a breakdown of its key features:

  • Speed and Reach: It supports data rates of up to 400 Gigabit Ethernet (GbE) over a distance of up to 2 kilometres (km) using single-mode fibre (SMF).
  • Form Factor: It uses the QSFP-DD (Quad Small Form-Factor Pluggable-Double Density) format, which is a compact and hot-swappable module for data centre applications.
  • Wavelength: It utilises Coarse Wavelength Division Multiplexing (CWDM) technology, transmitting data over four different wavelengths.
  • Standards Compliance: It complies with various industry standards including IEEE 802.3bs (400GBASE-FR4), 100G Lambda MSA group, and 400GAUI-8/CEI-56G-VSR-PAM4.

The QDD-400G-FR4-S allows you to connect network devices over fibre optic cables at very high speeds (400 GbE) for distances up to 2 km. It uses a standardised format (QSFP-DD) for easy installation and works with compatible equipment adhering to relevant industry specifications.
