Chinese Abstract

利用啁啾光纖光柵(CFBG)串聯的多波長色散補償器對長距離傳輸的8個信道信號進行色散補償,各個信道波長符合ITU-T標準,波長間隔為100 G。系統採用摻Er(上標 3+)光纖放大器(EDFA)作為功率放大器,在2015 km的G.652光纖上無前向糾錯(FEC)無電中繼實現8×10 Gb/s零誤碼傳輸。結果表明,利用CFBG構成的色散補償器各信道補償一致性好,CFBG不但能通過濾除帶外噪聲有效減小長距離傳輸中由放大器產生的自發輻射噪聲(ASE)的積累,提高傳輸信號的信噪比(OSNR),而且其較低的非線性特性有利於抑止信號劣化,從而有效提高長距離波分複用(WDM)的傳輸性能,擴展無電中繼傳輸距離。

English Abstract

The cascaded chirp fiber Bragg gratings (CFBGs), with ITU-T standard wavelengths and wavelength grid were applied to compensate the dispersion of 8×10 Gb/s WDM system. The ASE of the EDFA could be reduced, the OSNR of the transmitted signal could be increased and the fluctuation of the EDFA gain could be restrained in the certain scope by the CFBG employed in the system. Experiment of error-free 8×10 Gb/s 2015 km transmission without foward error correction (FEC) and electric relay were demonstrated. In the transmission, simplex booster of EDFA was used and no other form of dispersion compensator was adopted. The experiment results show that after 2015 km transmission, the consistency of the dispersion compensating in each channel is perfect.
