What is a QSFP28?

QSFP28 is a hot-pluggable transceiver module designed for a 100G data rate. QSFP28 integrates 4 transmit and 4 receiver channels. “28” means each lane carries up to a 28G data rate. QSFP28 can do a 4x25G breakout connection, 2x50G breakout, or 1x100G depending on the transceiver used.

100G BiDi transceiver refers to the QSFP28 single-mode fiber bidirectional optical module applied to 100G Ethernet.
