QDD-400G-DR4-S Optical Transceiver Module

QDD-400G-DR4-S Optical Transceiver Module

The QDD-400G-DR4-S is a high-speed optical transceiver module designed for data transmission over long distances on single-mode fibre (SMF). Here’s a breakdown of its key features:

  • Speed and Reach: It supports data rates of up to 400 Gigabit Ethernet (400GbE) over a reach of up to 500 meters.
  • Form Factor: It uses the QSFP-DD (Quad Small Form-Factor Pluggable Double Density) form factor, which is a compact and hot-swappable interface for data centre applications.
  • Wavelength: It operates at a wavelength of 1310 nanometres (nm).
  • Interface: It uses a MPO-12 connector, which is a multi-fibre connector that allows for the transmission of multiple data streams simultaneously.
  • Standards: It is compliant with several industry standards, including IEEE 802.3bs (400GbE), 400GAUI-8, and CEI-56G-VSR-PAM4.

The QDD-400G-DR4-S plugs into networking equipment and transmits information using single-mode fibre optic cables. It’s specifically designed for data centre applications where large amounts of data need to be transferred quickly and reliably.

Here is an additional point to note:

The QDD-400G-DR4-S can also be used for 4x100GbE breakout connections, meaning it can be used to transmit four separate 100GbE signals.
