Generally, an OLT is a switch or router and a multi-service provisioning platform.

An OLT (Optical Line Terminal) is a key component in fiber-optic access networks, particularly in GPON and XGS-PON systems. It serves multiple roles:

Switch or Router Role :

The OLT acts as a Layer 2/Layer 3 switch or router, aggregating traffic from multiple ONUs (Optical Network Units) and forwarding it to the core network.

Multi-Service Provisioning Platform :

The OLT supports multiple services, including Internet access (data), voice (VoIP), and video (IPTV). It integrates these services over a single fiber infrastructure, making it a versatile platform for service providers.

Why TRUE?

The statement accurately describes the OLT's functionality as both a switch/router and a multi-service provisioning platform.

Thus, the correct answer is A .
