An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a. It provides two main functions: 1. to perform conversion between the electrical signals used by the service provider's equipment and the signals used by the passive optical network.
In its most common form, a cube, a beam splitter is made from two triangular glass which are glued together at their base using polyester,, or urethane-based adhesives. (Before these synthetic, natural ones were used, e.g.) The thickness of the resin layer is adjusted such that (for a certain ) half of the light incident through one "port" (i.e., face of the cube) is and th.

A PON takes advantage of (WDM), using one wavelength for downstream traffic and another for upstream traffic on a (ITU-T, typically OS2). BPON, EPON, GEPON, and have the same basic wavelength plan and use the 1490 nanometer (nm) wavelength for downstream traffic and 1310 nm wavelength for upstream traffic. 1550 nm is reserved for optional overlay services, typically RF (analog) video.
●4 dBm: Lower transmit power, generally suitable for short-distance transmission (e. Different classes of optical transceivers (e. 25 dB/km at. This article systematically introduces the main categories and technical characteristics of OLT optical transceivers from four dimensions: form factor, rate specifications, optical power & transmission distance, and device compatibility. Form Factor The form factor determines the physical. In modern communication networks, optical line terminal (OLT) is the core device to realize point-to-multipoint (P2MP) in passive optical network (PON) architecture. The OLT is responsible not only for transmitting data from the core network to user terminals but also for managing bandwidth. Each port may be attached to the boards or network/line cards via a SFP module which must be a OLT module for it to have its Tx and Rx wavelengths swapped, but not all OLTs use SFP modules as shown in the image to the left. Multiple terminals at service access points within a radius of 20 kilometers are connected to form an EPON system network.
