ABSTRACT:
A bi-directional light signal separation device that separates light signals into the component incoming and outgoing light signals has a a female connector that is connected to a near end of a first fiber optic cable conveying the bi-directional light signal. A light signal separation device connected to the female connector to separate the bi-directional light signal into the individual incoming and outgoing light signals. A plurality of second type connectors connected to convey the individual incoming or outgoing light signals. The light signal separation device has a plurality of light filters and reflectors such that a light signal incoming to the second type connector is transmitted through the filter and conveyed to the female connector and such that the light signal incoming from the first connector and reflected by the light filter is reflected and conveyed to be outgoing on the second connector.
