100G QSFP28 SR4 100m Optical Transceiver

100G QSFP28 SR4 100m Optical Transceiver

Short Description:

The 100G QSFP28 SR4 100m Optical Transceiver integrates the transmit and receive path onto one module. The 100G optical transceiver converts parallel electrical input signals into parallel optical signals, by a driven Vertical Cavity Surface Emitting Laser (VCSEL) array. The transmitter module accepts electrical input signals compatible with Common Mode Logic (CML) levels. All input data signals are differential and internally terminated. The receiver module converts parallel optical input signals via a photo detector array into parallel electrical output signals. All data signals are differential and support a data rates up to 27.9525Gb/s per channel.ceiver module outputs electrical signals are…
