Gigabit optical modules have a transmission rate of 1. Direct communication between them depends on whether the network device supports auto-negotiation. Deployment flexibility with 800G (dual 400G), 400G, 100G, 50G, 40G, 25G, 10G or 1G modules. QSFP+ Universal transceiver for 40G operations over duplex multi-mode and single-mode fiber. Interoperable with IEEE 40GbE LR4 and LRL4 for easier migrations from 10G to 40G and to single mode fiber 100G. Optical modules enable mutual conversion between optical and electrical signals, making them essential for any application involving optical signal transmission. 7mm and complies with protocols such as SFP MSA (INF-8074i), SFF-8472 v9.
