YXFiber's 400G NDR Infiniband transceivers feature an OSFP package and include two models: 400G-SR4 and 400G-DR4. Utilizing four-channel PAM4 modulation technology, these transceivers achieve a single-channel rate of up to 100G and are fully compatible with Infiniband devices. Additionally, by changing the encoding, they can support Ethernet devices. They are widely used in data centers and AI high-performance computing, providing a low-power, low-latency, cost-effective, and high-performance network transmission environment.
