Patent KR-20020082437-A (KR)
Inventor: MIN SEONG SIK
IPC: H04J14/00
Filed: 2002-09-03
Abstract: PURPOSE: A variable optical encoder/decoder in an optical CDMA system using wavelength and time spreading is provided to use a small number of switches and a fixed length of optical fiber delays instead of using variable optical fiber time delays, thereby reducing size and cost of an optical switch and reducing the number of time delay elements. CONSTITUTION: A circulator(11) sets up a path of multi-length or wideband wavelength of optical signals supplied to an input port as being modulated according to user data via a predetermined light source. A wavelength multiplexing/demultiplexing element(3) separates the path-set optical signals by wavelength, and outputs the separated optical signals. Time delay elements(6,8) make the optical signals have different time delays according to wavelength. An optical switch(5) switches the optical signals outputted through the wavelength multiplexing/demultiplexing element to the time delay elements(6,8), and makes the optical signals pass through different time delay processes according to wavelength. Optical reflectors(7) reflect the switched optical signals, and retransmit the optical signals to the time delay elements(6,8).
