The second signal output pin of foot and Micro-processor MCV is simultaneously or separately turned on/off.If when the multiplexing functions of golden finger 101
When pin TRIG/TXDIS need to use originator control signal, the first control signal of Micro-processor MCV output is switched by low level
When for high level, Micro-processor MCV reads the second signal of the first signal output pin and Micro-processor MCV of Micro-processor MCV
The output logic state of output pin, and be I/O port by the function switch of PLA (programmable logic array) delivery outlet at this time, and make
The output state of I/O port is consistent with the output state of the PLA delivery outlet currently read, so that latch function is realized, so that at this time
The output of second signal output pin of the first signal output pin and Micro-processor MCV of Micro-processor MCV not will receive two-way
The influence of the signal of the controlled foot IN1 input of the first of switch chip U1, and in the process, the register of Micro-processor MCV
For storing the first control signal and second control signal of output, Micro-processor MCV is quickly matched according to the value of register readback
Set state (PLA mouthfuls or the IO of the first signal output pin of Micro-processor MCV and the second signal output pin of Micro-processor MCV
Mouthful), thus output signal, at this point, Micro-processor MCV is not involved in the processing of any signal, therefore response speed is quickly, reaches

Access conducting between second output pin NO1, the signal transmitted at this time are XGPON receiving end sampled signal and GPON receiving end sampling letter
Number, at this point, if when the signal of the second controlled foot IN2 output of two-way switch chip U1 is high level, two-way switch chip U1's
Access between second common signal foot COM2 and the third output pin NO2 of two-way switch chip U1 is connected, output GPON originator
Control signal.If the signal of the controlled foot IN2 output of the second of two-way switch chip U1 is low level, two-way switch chip U1's
Access between second common signal foot COM2 and the 4th output pin NC2 of two-way switch chip U1 is connected, output receiving end sampling
Signal is XGPON receiving end sampled signal.To realize two kinds of receiving end sampled signals and two kinds of originator controls in chip level
The multiplexing of four kinds of signals such as signal.So that the multiplexing function of the signal multiplexing pin TRIG/TXDIS of golden finger 101 is more various.
When the signal input pin 1 of Micro-processor MCV has input, if the multiplexing functions pin TRIG/TXDIS of golden finger 101 need using
When receiving end sampled signal, Micro-processor MCV is low level in the output of first control signal output pin, according to Micro-processor MCV
The signal type that signal input pin 1 inputs is from the first signal output pin of Micro-processor MCV or the second letter of Micro-processor MCV
Number output pin exports corresponding signal, can be realized Micro-processor MCV the first signal output pin and Micro-processor MCV second
Signal output pin is simultaneously or separately turned on/off.When the multiplexing functions pin TRIG/TXDIS of golden finger 101 need to use originator
When controlling signal, when the first control signal of Micro-processor MCV output is switched to high level by low level, Micro-processor MCV is read
The output logic state of the first signal output pin of Micro-processor MCV and the second signal output pin of Micro-processor MCV is taken, and will
The function switch of PLA (programmable logic array) delivery outlet at this time is I/O port, and makes the output state of I/O port and currently read
The output state of the PLA delivery outlet arrived is consistent, so that latch function is realized, so that the first signal of Micro-processor MCV at this time
The output of the second signal output pin of output pin and Micro-processor MCV not will receive the first controlled foot of two-way switch chip U1
The influence of the signal of IN1 input.
101 multiplex circuit of the present embodiment golden finger includes two-way switch chip U1 and Micro-processor MCV, so as to pass through
Micro-processor MCV provides the internal path of two or more driving signal switching two-way switch chip U1 to carry out golden finger
The multiplexing of the multiple functions of 101 1 pins, i.e. 101 multiplex circuit of the present embodiment golden finger solve existing golden finger 101
The single problem of single pin function.
To achieve the above object, multiple including golden finger 101 as above as shown in figure 3, the present invention also proposes a kind of optical module
