ABSTRACT:
An optical communications network which connects a central office with a plurality of user stations is disclosed.
In the central office, the power from a single cw laser is divided over a plurality of single mode optical fibers to transmit information from the central office to the user stations. Each user station includes a directly modulated LED for transmitting information to the central office.
