The 100G optical transceivers series include different form factors such as QSFP28 and CFP4. Optechâ??s 100G Transceivers includes QSFP28-SR4, QSFP28-LR4, QSFP28-ER4, QSFP28-BIDI, QSFP28-PSM4 and QSFP28-IR4. It offers connecting solution from 100m to 40km for data centers, high speed network and 5G. The name of the 100G QSFP28 comes from the fact that its electrical interface can handle four channels of 25G each, potentially up to 28G.
