Is the core switch an OLT

Home / Is the core switch an OLT

The OLT is the core component of the optical access network, which is equivalent to a switch or router in a traditional communication network, and is also a multi-service providing platform. OLT (Optical Line Terminal): - Function: OLT is a key component in a Passive Optical. It converts data signals, manages bandwidth, and connects hundreds of users over a single optical fiber infrastructure. Active Optical Networks (AONs) and Passive Optical Networks (PONs) are the two main systems that make up FTTH broadband connectivity, and PONs, which can provide cost-effective solutions, are more prevalent in most FTTH deployments.
