400G QSFP112 including 400G QSFP112 SR4-IB, 400G QSFP112 SR4, 400G QSFP112 DR4, 400G QSFP112 FR4, 400G QSFP112 LR4.
400G QSFP112 is a high-speed optical transceiver package that utilizes four 112 Gbps electrical channels to achieve a total transmission rate of 400 Gbps. It is primarily used for high-speed interconnections within data centers, such as between servers and switches. Compared to 400G QSFP-DD solutions requiring eight channels, its advantages include lower power consumption, simplified thermal management, and better compatibility with existing switch ports designed for 100G rates, facilitating network upgrades.
