Cisco QSFP-400G-DR4= network transceiver module Fiber optic 400000 Mbit/s QSFP112 1310 nm

The Cisco QDD-400G-DR4-S module supports 400GBASE-DR4 links and up to four 100G DR1 or two 200G DR2 breakout link lengths of up to 500 m. The module has four pairs of single-mode fiber (SMF) with an MPO-12 connector. It is compliant with the IEEE 802.3 and 400GAUI-4 standards. The 400G signal is carried over four pairs of parallel fibers by one wavelength per fiber. It can be used 200G DR2 link for 200GE ports by using two pairs of fibers. Forward Error Correction (FEC) is performed on the host platform.
