The 800G SR8 DML/EML solution uses an 8x100G DSP, the same-wavelength DML/EML optical chip, with 8 fibers (PSM8 parallel single-mode 8 channels) used on both the transmitter and receiver sides, and employs 24-core or 16-core MPO connectors. The next key development is 800G, and the industry is already gearing up to deploy this next generation of client optics in hyperscale data centers. Developments in three distinct areas are needed for 800G deployment: optical modules and direct attach copper (DAC) cables, switch ASICs, and 800GE. 800 Gigabit Ethernet (800GE) routing is the next generation IP networking technology enabling operators to upgrade router interfaces to 800 Gb/s. It leverages the most recent QSFP-DD interface module specifications to support high-density 800GE pluggable optics with backwards compatibility for. Delivering up to 800 Gbps of bandwidth, Orion provides the performance that will effectively allow coherent pluggable modules to be used across most—if not all—optical spans in today's telecommunications networks. Orion-based modules will also provide data centers the much-needed bandwidth boost. The application scenarios for 800G optical modules are primarily divided into SR (100m), DF/FR/LR (500m/2km/10km), and ER/ZR (40km/80km). The connection distance between Top of Rack (TOR) switches and Leaf switches is relatively short. 800G: the hype is real, and the wait is over. No more guessing or predicting the speeds and. Two different mechanical form-factors for these 400G modules, QSFP-DD and OSFP, were introduced to the market, with the former being the primary form-factor being shipped today for 400G, matching the widely adopted host platform QSFP-DD slots.
