The output optical power of the ODN optical splitter is normal
The optical power attenuates after being transmitted through the optical components or optical fibers. If the actual attenuation is much larger than the theoretical value, abnormal attenuation point. In the backbone of modern Fiber-to-the-Home (FTTH) networks, optical splitters serve as the unsung heroes that enable cost-efficient connectivity for millions of subscribers. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network. The traditional ODN (Optical Distribution Network) typically employs a uniform fiber splitting approach, with fiber splitters mainly in configurations of 1×4, 1×8, or 1×16, as illustrated in Figure 1. The Optical Distribution Network (ODN) is the passive fiber infrastructure that connects the central office OLT to each subscriber in FTTH, FTTB, and FTTO deployments. They are named by the number of inputs and outputs, so a splitter with one input and 2 outputs is a 1X2, and a PON splitter with one input and 32 outputs is a 1X32. Some PON splitters have two inputs so it.
