Generic Compatible 400GbE QSFP-DD SR8 PAM4 FEC Optical Transceiver Module (850nm 100m MMF MTP/MPO )
400GbE QSFP-DD SR8 transceiver module is designed with 4x 50Gb/s PAM4 modulation for up to 100m over OM4 transmission multimode fiber. NADDOD 400GbE QSFP-DD SR8 Optical Transceiver supports eight electrical interface channels that operate in 50G PAM4 coding mode to produce 400G (8x50G) data rates. It is compliant with the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standard. The transceiver can offer customers a wide variety of super high-density 400 Gigabit Ethernet connectivity options for data centers, high-performance computing (HPC) networks, enterprise core and distribution layers, and service provider applications.
Based on the Spine-Leaf architecture, upgrading from 200G to 400G using NADDOD optical modules can help customers reduce network costs, improve data transmission speed, and enhance data processing capabilities.
NADDOD 400G optical transceiver has great advantages in increasing data throughput and maximizing data center bandwidth and port density. 400G QSFP-DD has been tested and recognized by the global market as we are the first brand to complete the commercial order delivery of 400G data center optical modules.
NADDOD has a full range of professional testing equipments for testing various parameters of products to ensure high performance and quality of optical transmission stability.
