SPBD-1250B4Q1RT Notes: 1) Circuit ground is internally isolated from frame (chassis) ground. Tx GND and Rx GND may be internally isolated within the TRx module. 2) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K~10K Ω resistor on the host board. Pull up voltage between 2.0V and VccT+0.3V. The output indicates Low when the transmitter is operating normally, and High with a laser fault including laser end-of-life. In the low state, the output will be pul
