A simple technique is presented to determine splice losses between two identical
arbitrarily graded index single mode fibers for transverse and angular misalignments. The
power transmission coefficients at the splice are calculated in terms of spot size using
Marcuse formulation for graded index fibers. Our values of splice losses match
excellently with the exact one and also other results available in literature. The technique
should attract attention of experimentalist as a simple alternative of rigorous methods to
estimate propagation characteristics
