2.4 Determining Fiber Loss
There are many ways to determine fiber loss. Here are two examples:
2.4.1 Fiber Terminated in Patch Panels
1) Using three test jumpers with interconnect sleeves, connect the optical source to the
TFC200 (see Fig 2.2). The test jumpers should be one to five meters long and be the
same type as the fiber under test (singlemode or multimode, core and cladding size).
