as to the origin of any operational failure. Be certain that the input and
output signal connections are proper. Due to the number of positions,
Finally, although multimode and single mode devices may look the
same, they will not operate properly together. Using the wrong device
or fiber can easily add more attenuation than specified, resulting in poor
overall performance.
