Inventor: JUNG MU GIL
IPC: H04B10/2581
Filed: 2000-12-27
Abstract: PURPOSE: An optical multi-separating apparatus for transmitting a point-to-multipoint radio optical data is provided to minimize a loss of an optical output for spatially separated optical receivers and enable a point-to-multipoint transmission for transmitting information simultaneously by separating a light and focussing and transmitting the light only to a required object. CONSTITUTION: A network interface card(301) is mounted at a computer. A data format converting circuit(302) converts data transmitted through a wired cable connected to the network interface card(301) to a data formation suitable for optical transmission. A data modulation and amplification circuit(303) carries the converted data format on a laser. An optical multi-separating module(304) separates the laser light into several ones. The optical multi-separating module(302) includes a laser for generating a laser light, a reflecting plate for separating a laser light travelling straight, and an alignment control module for controlling the direction of the laser light and a rail. In separating the laser light, the data format converting and modulation amplification circuits(302,303) changes a specific type of data received through a wired cable from the network interface card(301) of the computer to an optical signal form which can be carried on the laser light. The laser unit renders the light to travel straight and in parallel with small size of points, and as for this format of laser light, only one light receiver positioned on the proceeding line of the laser light can receive the data. The straightly travelling laser light is separated into laser lights as many as existing reflecting plates when it passes the reflecting plates. In order for each of the reflected laser light to reach a target point, the alignment control module controls a reflection angle of the reflecting plate. The alignment control module transmits the laser lights to neighboring light receivers.
