Module 100G QSFP28 (Quad Small Form-Factor Pluggable)
According to different form factors, 100G transceivers can be usually divided into CFP, CFP2, CFP4, CXP, and QSFP28 Among them, CFP, CFP2, CFP4, and CXP are the early form of 100G optical transceiver, but QSFP28 is the newest version of 100G Optical transceiver, because of its lower power consumption and higher density, it has become the mainstream form of 100G optical transceiver. Like 40G QSFP + with 4 x 10Gbps channels, 100G QSFP28 is implemented with 4 x 25Gbps channels.
