Question

Looking at the table that shows the relationship between current in the two different transmitting diodes and the produced voltage at the receiver. Which transmitting diode is better for transmitting a signal over a fiber optical cable? and why?

V/[v] I1/[mA] I2/[mA]

0,50 0,60 0,60
0,80 0,60 0,60
0,90 0,60 0,60
1,00 0,25 0,50
1,10 3,80 0,40
1,20 37,30 1,40
1,30 135,00 27,50
1,40 ... 132,00
1,50 ... ...

Answer 1

To transmit a signal over a fiber optic cable, the transmitting diode with the higher voltage is preferred.

Step-by-step explanation:

In order to determine which transmitting diode is better for transmitting a signal over a fiber optic cable, we need to consider the relationship between current and voltage. The power transmitted (Ptransmitted) is equal to the product of the transmitted current (Itransmitted) and the transmitted voltage (Vtransmitted). The power lost (Plost) is equal to the product of the transmitted current (Itransmitted) and the transmitted voltage (Vtransmitted).

To minimize power lost and improve transmission efficiency, we need to minimize the transmitted current by maximizing the transmitted voltage. Therefore, the transmitting diode with the higher voltage (V/[v]) is better for transmitting a signal over a fiber optic cable.
