The OLT is connected to the optical splitter through a single optical fiber, and then the optical splitter connects to ONUs/ONTs. GPON adopts WDM to transmit data of different upstream/downstream wavelengths over the same ODN. Executive Summary: A fiber optic pigtail is one of the most commonly specified yet least understood components in structured cabling. Get the wrong connector type, the wrong polish, or skip proper fusion splicing technique—and you're looking at elevated signal loss, increased back reflection, and a. ODN is a completely passive optical network, which is composed of optical cables, optical distribution boxes, optical closures, optical splitters, etc. Each ODN consists of 3 segments: feeder segment or feeder optical cable, distribution segment or distribution optical cable, and drop segment or. They are the bridge between fiber optic cables in the field and the equipment or patch panels that manage them. Realize the control, management, and ranging functions of user equipment ONU. Optical Network Termination (ONT).
