MFD and NA are very important parameters which define fibers' feature. When we splice two kinds of fiber with different MFD and NA, splice loss will be much higher than that if they are the same. In order to deduce the loss, MFA are developed which can largely optimize splice mode, usually can get a <0.5dB, even <0.3dB loss between different fibers.

From small MFD fiber direction to large MFD fiber directioin is defined as F-Forward, large MFD fiber to small MFD is B-Backward.
