摘要： Provided are a passive optical network system and a method of transmitting a broadcasting signal in the same system. A central office (CO) generates a broadcasting signal and a downstream optical data signal using a coding method guaranteeing a run-length, multiplexes the downstream optical data signal and the broadcasting signal, and transmits the multiplexed downstream optical data signal and broadcasting signal. A remote node (RN) transmits the multiplexed downstream optical data signal and broadcasting signal received from the CO to one or more optical network units (ONUs). A gain medium, which is located on a transmission line between the CO and the RN, amplifies the broadcasting signal using the downstream optical data signal as a pump light source. Accordingly, a high gain can be obtained by amplifying the broadcasting signal using the gain medium located on the transmission line without a separate pump light source.

摘要： An optical diplexer module includes: an optical diplexer module comprising: a multiplexing unit multiplexing RF signals and a wideband digital signal having a baseband bandwidth to output a single multiplexed signal; an E-O converter converting the multiplexed signal into an optical signal and externally outputting the optical signal; and an O-E converter converting an externally received optical signal into an electric signal and outputting the electric signal. Similarly to existing optical transceivers, the optical diplexer module can provide TPS and MPS services using only two optical wavelengths for upstream and downstream signals. Since no separate optical wavelength is additionally required, the optical diplexer module can allows the numbers of components and processes to be reduced. It may result in yield improvement and cost reduction. Also, since electric or optical crosstalk between modules can be reduced, its performance can be improved.

摘要： Provided is an image extraction method of optical phase extraction system. The image extraction method may include checking whether a phase error due to an environmental disturbance of optical fiber occurs by monitoring an output signal obtained by interfering reflection optical signals reflected through two paths. When a phase error occurs, an error is compensated using a phase compensation control method of closed loop type through one of the two paths and an image is extracted by capturing an image of object in a state that the image of object is shifted by the set phase value when a phase error is compensated. According to the inventive concept, a phase error occurring in an optical fiber type interferometer due to an environmental disturbance is minimized or compensated. Also, since an interference image accurately shifted by the phase value set among arbitrary various phase values is obtained through a camera, reliability of three-dimensional phase information being extracted is guaranteed.
