What is Splice Loss?
High splicing loss caused by few number factors. However, most high splicing loss are due to workmanship for example
There are high splice loss due to manufacturing defects as shown below :
End result of splicing due to fiber misalingment or lateral offset and cladding diameter mismatched - osa.org
Splicing loss as indicated on the fusion splicing machine is based upon estimation only.
In order to get accurate splicing loss you need to check with OTDR as shown below. You need to obtain splicing loss by shooting OTDR from A to B and from B to A
Assuming the obtained both splice losses are as below :
a. From A to B is -0.04dB
b. From B to A is -0.02dB
Using averaging formula below the final splice loss is -0.03dB
I have been in the field of fiber optics since early 1990s. I gained fiber optics skills and knowledge via my working experience as end-user, main contractor and sub-contractor and finally as an optical fiber enterpreneur.
