The Profile Alignment System is a technique for using non electro-optical linked access technology for aligning fibres for fusion splicing.
Jumper cords: Interconnect cables: Short distance cables, usually with connectors pre-installed on both ends, used to connect between equipment, and generally between two and ten meters long.
Plastic Clad Silica. A multimode fibre composed of a glass core and plastic cladding.
A fibre optic cable assembly consisting of a connector and an unterminated fibre at the other end. Normally in applications wherein a splice is convenient for terminating a device with a connector.
Plastic Optical Fibre. A multimode fibre composed of a plastic core and plastic cladding.
A Passive Optical Network (PON) is made up of fibre optic cabling and passive splitters and couplers that distribute an optical signal through a branched "tree" topology to connectors that terminate each fibre segment. Compared to other access technologies, PON eliminates much of the installation, maintenance and management expenses needed to connect to customer premises. Per the FSAN specifications PON is a point to multipoint system with one OLT at the central office servicing up to 32 ONTs. The system is single fibre with downstream traffic sent in the 1550nm wavelength window and upstream traffic being sent in the 1310 wavelength window. This is an example of Bi-directional transmission on a single fiber. Sometimes the PON is called B-PON, which indicates it is a Broadband PON. Also it can be an APON, which is an ATM based PON or an EPON, which is an Ethernet based PON.
Plain old telephone service.
A glass structure from which an optical fibre may be drawn.
Fusing with a low current to clean the fiber end.
The plastic coating applied directly to the cladding surface of the fibre during manufacture to preserve the integrity of the surface.
Public Switched Telephone Network is the traditional voice network infrastructure, including both local service and long distance service. It has been in use in various parts of the world for up to a century or so.
(Pulse Spreading) - the separation or spreading of the input characteristics of the optical signal that appears along the length of the optical fibre and limits the useful transmission bandwidth of the fibre. Three basic mechanisms for dispersion are the material effect, the waveguide effect and the multimode effect.
