OLT stands for “Optical Line Terminal.” It’s a critical device in a passive optical network (PON) that serves as the endpoint of the network on the service provider’s side. The OLT connects to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs), which are located on the customer’s premises. OLTs manage and distribute data, voice, and video services over optical fibers, making them a crucial component in delivering high-speed broadband services in fiber-optic networks.

SFP stands for “Small Form-factor Pluggable.” It’s a compact, hot-pluggable transceiver module used in networking equipment to provide interfaces for various types of optical and electrical communication standards. SFP modules are commonly used in switches, routers, and other networking devices to enable flexible connectivity through interchangeable modules, supporting different data rates, distances, and types of connections, such as fiber-optic or copper Ethernet.
