Arista Compatible Coherent VCSEL & Broadcom DSP 400G QSFP-DD SR4 PAM4 850nm MTP/MPO-12 OM4 100m Optical Transceiver Module
NADDOD Arista QDD-400G-SR4 compatible 400G QSFP-DD SR4 optical module is a multimode, four-channel (SR4) transceiver designed for 400 GbE links over up to 100 m of OM4 multimode fiber. It converts eight 50 Gb/s PAM4 electrical input channels into four 100 Gb/s PAM4 optical channels, operating at a nominal wavelength of 850 nm to deliver an aggregate data rate of 400 Gb/s.
The 400G QSFP-DD SR4 optical transceiver delivers ultra-high-density 400 Gigabit Ethernet connectivity for data centers and high-performance computing (HPC) networks. It can be connected to NICs with QSFP112 or OSFP ports and is well suited for short-reach interconnects between switches and network interface cards, supporting a wide range of device-to-device interconnection scenarios.
This solution provides seamless interconnectivity between QSFP-DD switches and OSFP network cards, addressing the compatibility issues between different port form factors. It ensures a seamless connection between devices with different port enclosures.
