Optical Transmission Components A variety of components manipulate optical signals in the transmission system. The components fall into 2 broad categories: s Passive Components that require no external power. LT/CTS-04B/1009 2 of 18 s Active Components that need external power or modify the signal. The components play part in splitting or combining signals, switching, modulating and others. Fiber Optic components are assembled into systems to provide telecommunication services.

Coupler Coupler is a passive component that splits input signal into two or more outputs or combine twom or more inputs to one output. Couplers connect three or more points. Optical couplers is packaged with connections on the LT/CTS-04B/1009 4 of 18 outside. Divided optical signal reduces its strength. Coupler applications: s Tapping signals in a LAN s Delivering CATV to many subscribers s Splitting wavelength

Coupler Connectors and splices join 2 fiber ends together for sending signals between 2 devices. Many applications require connections to more than 2 devices. A coupler makes fixed connection among three or more points. LT/CTS-04B/1009 5 of 18 Some couplers are called Tabs because they divert part of a signal through a communication system to another point. Couplers are often packed into a box to protect it from the environment. Couplers are similar to splitters that have one input and several outputs.
