英文摘要	A single mode optical fiber manufacturing process can be monitored and/or controlled determining the mode field radius and/or the cut-off wavelength of fiber produced by the process, comparing these measured fiber parameter values to predetermined target values, and setting a process step in accordance with the result of the comparison. Both fiber parameters are determined by a procedure comprising measuring, as a function of angle, the far-field power emitted by a test fiber segment, and determining the parameters of a Gaussian function G( theta ), typically by maximizing the value of an overlap integral.
