Term
Fiber Optic Cable
Definition
A type of network cable in which the core is one or more glass or plastic strands. Core:5-100microns thick surrounded by cladding which reflects light back into the core in patterns determinded by the transmission mode
Term
How thick is the outer diameter of a fiber optic cable?
Definition
125 microns thick(125 millionths of a meter or 5 thousandths of an inch)
Term
Multi-mode Fiber
Definition
Allows light to travel within its core in MULTIPLE RAYS or MODES. Its core of 50-62.5 microns works with LED sources for slower LAN's and with lasers for faster networks in the gigabit range
Term
Single-mode Fiber
Definition
A core of only 9 microns(smaller than multi-mode fiber).Light travels in only one direction. Uses lasers to process telephony and CATV transmissions

Straight Tip(ST)

Used to connect multi-mode fiber. Often used in network patch panels(most popular)

Definition

Subscriber Connector/Standard Connector(SC)

Often used in a duplex configuration where two fibers are terminated. SC is used with single-mode fiber

Term

Definition
Similiar to SMA. FC use a heavy duty ferrule for mechanical stability. Used in industrial settings where greater strength is required

Fiber Distributed Data Interface(FDDI)- Is a push pull type, two channel snap fit connector used for multi-mode fiber
Term

Definition
Biconic Connector- Is a screw-on type connector with a tapered sleeve that is fixed against quided rings and screws to secure and pull the connection into place.(early connector most likely no longer in use)
Term

Definition
Local Connector(LC)- Is a small form factor ceramic ferrule connector for both single and multi-mode fiber. Uses a RJ-45 type latching connector, used to transition twisted pair to fiber
Term

Definition
Sub Mulit Assembly/Sub Miniature type A-Similiar to ST connectors, SMA are typically used  where waterproof connections are needed
Term

Definition
Mechanical Transfer Registered Jack: Sometimes called a Fiber-Jack connector, is a compact snap-to-lock connector used for multi-mode fiber. Two strands of fiber are attached with one connector
