YM-101
Detail
YM-101 is a hybrid type optical isolator having an isolator function and a gain flattening filter function (GFF).
Complexation of functions contributes to space saving in the amplifier. Filters are manufactured using thin film technology and the GFF profile is designed according to requests.
Features
Complexation of two functions (isolator + gain flattening filter function)
