Optical Y-junction power splitter

In terms of performance, communication by optical fiber is potentially the most rewarding of all communications. It has been suggested that if the full potential of fiber optic communication is realized, a single fiber would be sufficient to serve the needs of telecommunication users (heavy data tra...
