| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | SD-SDI/HD-SDI are serial interface standards of the uncompressed digital video signal, and well adopted in TV broadcasting equipments. There are optical SD-SDI/HD-SDI transmitting and receiving systems with loss budget of 10dB, however the loss budget increase will be requested to realize long distance live relays. SD-SDI/HD-SDI are signals containing the burst of 53μs/26μs at most. On the other hand, the waveform of a burst containing signal (below about 10kHz) is distorted when the signal is amplified by a conventional optical fiber amplifier. Therefore, it has been difficult to amplify the SD-SDI/HD-SDI signal by a conventional optical amplifier and to increase the loss budget. Therefore, we propose to apply the "Gain-Clamped Optical Fiber Amplifier" (GC-Amp.) for amplifying bursty SD-SDI/HD-SDI signals. Experiments show that our GC-Amp. lineally amplifies bursty SD-SDI/HD-SDI signals without waveform distortion and the loss budget is enhanced. | |
