Check Fiber Alignment: Ensure that the fiber is properly aligned with the input and output ports of the splitter. Use precision tools to align the fibers correctly. So for this simple 1X2 splitter, how do we test it? Simply follow the same directions for a double-ended loss test. Attach a launch reference cable to the test source of the proper wavelength (some splitters are wavelength dependent), calibrate the output of the launch cable with the meter to set. Using a 32 port G-PON as an example, the following scenarios are applicable to troubleshoot and identify problem splitters. ScenariosIf the splitter is placed at the central office (CO,) known as a home run topology, and all 32 subscribers are out of service, the failure could be caused at the. Fiber optic splitters distribute optical power from one input fiber to multiple output fibers through either fused biconical taper (FBT) coupling or planar lightwave circuit (PLC) waveguide structures. Their performance depends on optical symmetry, waveguide integrity, and mechanical stability of. Insertion loss is the ratio of the optical power launched at the given input port of the splitter to the optical power from any single output port.
