Launching of Power and Coupling in Optical Fiber
Launching of Power and Coupling in Optical Fiber
SOURCE TO FIBRE POWER COUPLING:-
– Nowadays many source suppliers offer a short optical fiber attached to power coupling sources.– This small optical fiber is known as a fly lead or pigtail. .
– These reduce the power launching problem.
FIBER SPLICING:-
–It is a permanent bond between two fibers.
– These bond is made by using fusion splicing.
– Temporary splices is necessary when one is making or troubleshooting.
OPTICAL FIBER CONNECTORS:-
– They are made by combinations of two or three letters.
– There are different types of optical fiber connectors like:-
ST connector- They are used in applications like data communication and telecommunication.
SC connector
-It stands for subscriber connector or square connector.It is widely used in LAN,WAN and telecommunication networks.
-it is also used in simplex or duplex configurations.
FC connector-
–It stands for Fiber channel and is used in fiber channel applications like terminating the jumper.
– It is works on thread coupling mechanism.
LC connector
-It is used for high-density fiber optic connectivity.
-It aligns the fibre core to achieve low insertion loss.
– It is available in both simplex and duplex mode..
