Q.	2 BASIC OPTICAL LAWS AND DEFINITIONS, OPTICAL MODES AND CONFIGURATIONS
A.	lower purity
B.	higher purity than multimode step index fibers.
C.	no impurity
D.	impurity as same as multimode step index fibers.
Answer» B. higher purity than multimode step index fibers.
Explanation: multimode graded index fibers have higher purity than multimode step index fiber. to reduce fiber losses, these fibers have more impurity.
