Abstract A cut-off wave-guide pip is a hollow conducting pipe. It is often used as
necessary components of EM shielded rooms. This article profoundly analyses the
reason of the debase of EM shielded room’s shielding effectiveness brought by optical
fiber from the stump of Maxwell Equation,and gives the derivation of some formulas
relative to the problem. Lastly, the modified formulas and method according with
practical application are given.
