Optical Line Terminal OLT

An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions:

1. to perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network.
2. to coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).

The diagram below depicts an OLT within a fiber-optic network.

An optical line terminal (OLT) is the endpoint hardware device in a passive optical network (PON). 

An OLT has two primary functions:

1. Converting the standard signals used by a FiOS service provider to the frequency and framingused by the PON system.
2. Coordinating the multiplexing between the conversion devices on the optical network terminals(ONTs) located on the customers' premises.

The OLT contains a central processing unit (CPU), passive optical network cards, a gatewayrouter (GWR) and voice gateway (VGW) uplink cards.  It can transmit a data signal to users at 1490 nanometers (nm). That signal can serve up to 128 ONTs at a range of up to 12.5 miles by using optical splitters.
