Insertion Loss vs Return loss
Insertion loss and return loss are an indication of important values to evaluate the quality of fiber optic patch cords, pigtails or connectors termination.
What is Insertion Loss ?
In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or in other words Insertion loss refers to the fiber optic light loss caused when a fiber optic component insert into one another to form the fiber optic link.
Absorption, misalignment or air gap between the fiber optic components are the main cause contribution to Insertion Loss.
What is Return Loss ?
In telecommunications, return loss is the loss of power in the signal reflected by a discontinuity in fiber optics (connectors) or in other words Return loss is the fiber optic light gets reflected back at the connection point.

I have been in the field of fiber optics since early 1990s. I gained fiber optics skills and knowledge via my working experience as end-user, main contractor and sub-contractor and finally as an optical fiber enterpreneur.
