What is OLTs?

An Optical Line Terminal (OLT) is a device which serves as the service provider endpoint of a passive optical network (PON). An OLT typically provides the interface between the PON and the service provider's core network. It aggregates and manages traffic from multiple Optical Network Units (ONUs) located at customer premises, providing services such as internet, VoIP, and video. The OLT transmits data downstream to the ONUs and receives data upstream from the ONUs.

OLTs Complementary Technologies

VFL

A Visual Fault Locator (VFL) is used to visually trace fibers and locate breaks, splices, and connectors. This is complementary to OLTs, which provide the main data transmission but rely on a properly functioning fiber network.
