QSFP28

QSFP28 is a hot-pluggable transceiver module designed for 100G data rate. Unlike the older 100G CFP, CFP2 and CFP4 interfaces, the newer QSFP28 interface offers a much smaller form type. Due to its size this interface is becoming the standard interface choice for 100G transmission. QSFP28 integrates 4 transmit and 4 receiver channels. QSFP28 ramps up the data speeds to 100G by using 28Gbps per channel. QSFP28 can do 4x25G breakout connection, 2x50G breakout, or 1x100G depending on the transceiver used. While QSFP+ supports the data rate of 40G, 4 channels for transmitting and 4 channels for receiving, each lane carrying 10G. 100G QSFP28 transceivers come in types like 100GBASE-SR4, 100GBASE-PSM4, 100GBASE-CWDM4 and 100GBASE-LR4,
