By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network. PON (Passive Optical Network) is a fiber-based broadband access technology, with core components including OLT, ODN, and ONU. Its single-fiber bidirectional transmission mechanism employs WDM, where downstream traffic adopts broadcast mode (1490nm wavelength), and upstream traffic uses TDMA. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. The Asia Pacific region (APAC) leads worldwide consumption of Planar Lightwave Circuit (PLC) splitter compact devices with a 68% share, followed by the Americas and the EMEA (Europe, Middle East, and Africa) region.
