近年來,對於數位視訊廣播、高解析度電視、網路協定電視的頻寬需求有日益漸增的趨勢。為了滿足上述的頻寬需求,一種結合光載波與高頻電訊號的微波光纖通訊系統將會是最好的解決之道。所以,在本篇論文中提出了多波長雷射模組於廣播與通訊系統之應用。相較於先前的廣播傳輸系統,此系統的廣播訊號光源可藉由調整半導體雷射來達到不同的光載波波長間距。此外,為了瞭解本系統的傳輸效能,在0km及經由25km光纖傳輸後的情況下,分別分析625Mb/s的偽隨機位元序列與312.5Mb/s的正交分頻多工-四位元相位偏移調變廣播訊號之誤碼率。根據實驗的結果顯示,偽隨機位元序列與正交分頻多工-四位元相位偏移調變廣播訊號都符合傳輸規範。

Recently, there have tremendous bandwidth demand of broadcast service such as DVB, HDTV, and IPTV. In order to fulfill the bandwidth demand, radio over fiber (ROF) communication systems which integrates optical and radio signal is highly promising for satisfy such requirements. So, this work presents a multi-wavelength laser diode for broadcast and communication system applications using a reflective semiconductor optical amplifier (RSOA). In contrast to the previously broadcast transport systems, this broadcast light source free spectral range (FSR) can tunable. Additional, to demonstrate systems performance, which is analyzed pseudo random binary sequence (PRBS) 625Mb/s or orthogonal frequency division multiplexing (OFDM) - quadrature phase shift keying (QPSK) 312.5Mb/s broadcast signal by using bit-error-rate (BER) measurements for back to back (BTB) and 25km fiber transmission. According to the experimental results, excellent performances of BER is achieved for PRBS broadcast signal applications, along with OFDM broadcast signal transmission achieved as well.
