Supports both 100G and lower-rate Ethernet applications using the same optical architecture as the standard LR4. Transmits four wavelengths (1295. 1 nm) over SMF via LC interface. Offers hot-plug capability, low power draw, and diagnostic functions via I2C. The QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet and 4x 28G OTN client interfaces throughput up to 70m over OM3 multimode fiber (MMF) or 100m over OM4 multimode fiber (MMF) using a wavelength of 850nm via MPO12 connectors. It is intended for use in inter- and intra-connect applications within and between data centers between switches, routers, sto age equipment etc. The optical performance is in accordance with.
