Q.	How many fabrication techniques are used for 3 port fiber couplers?
A.	one
B.	two
C.	three
D.	four
Answer» B. two
Explanation: there are two fabrication techniques available for three port couplers. first is a lateral offset method which relies on the overlapping of the fiber end faces and the other is the semi-transparent mirror method. using these techniques, three port couplers with both multimode and single-mode fibers can be fabricated.
