Other users will ask the following questions:
1.What fiber link is needed for light source and power meter
execution?
A light source and a power meter are required to perform the most
important measurement of a fibre optic link, the total insertion
loss of that link. Basically, you compare the amount of light going
into one end of the fibre with the amount of light coming out of
the other end of the fibre.
.
2.What is good dBm for fiber?
Positive dBm means power greater than 1mw and negative means less
than 1mw. A good laser source for a singlemode link will have a
power output of ~ +3 to +6 dBm - 2-4mw - coupled into the fiber. A
VCSEL for multimode links should have a power around 0dBm - 1mw.
