QSFP28 850nm 100G 100m Transceiver
QSFP28 850nm 100G 100m Transceiver

The QSFP28 100G SR4 optical transmitter portion of the transceiver incorporates a 4-channel 850nm VCSEL (Vertical Cavity Surface Emitting Laser) array, a 4-channel input buffer and laser driver, diagnostic monitors, control and bias blocks. For module control, the control interface incorporates a 2-wire serial interface of clock and data signals. Diagnostic monitors for VCSEL bias, module temperature, transmitted optical power,received optical power and supply voltage are implemented and results are available through the 2-wire serial interface. Alarm and warning thresholds are established for the monitored attributes. Flags are set and interrupts generated when the attributes are outside the thresholds. Flags are also set and interrupts generated for loss of input signal (LOS) and transmi
