Abstract
Techniques for monitoring optical power, dispersion and mode distribution in high speed multimode fiber are described. According to one aspect of the present invention, a multimode optical tap filter is disclosed. The tap filter is dispersionless and tap ratio independent, and packaged in a 3-port form factor. To be efficient in cost, at least two such optical tab filters are packaged in one device while sharing a single thin film filter provided to reflect a predefined portion of a signal being monitored.
