Development of uncompressed multichannel digital video optical fiber transmission system
無壓縮多路數字視頻光纖傳輸系統的研製 -
Initially, pdh was introduced to improve and replace the obsolete analog frequency division multiplex ( fdm ) system. however, it was soon found that pdh had shortcomings such as difficulty in management, high construction cost, limited applications and lack of connectivity standards at the optical layer. thus, in the early 1990s, synchronous digital hierarchy ( sdh ) was introduced in the transmission system
Pdh最初引入是為了改進和替代老式的模擬頻分復用器系統，但很快被發現pdh管理困難、造價高、應用范圍窄，且缺乏在光層面上的連接標準，因此90年代初期， sdh （ synchronousdigitalhierarchy ）標準被首先引入了傳輸系統。 -
The rtmaad system was integrated with digital signal processing ( dsp ), global information system ( cis ), optic time domain reflective ( otdr ) meter technology, wave division multiplexing ( wdm ) technology, etc. the rtmaad system made a realization that optical cable " s abort is auto located exactly. at the same time, the rtmaad system can monitor and diagnose both the optical terminal " s fault and power " s error of the stations of the fiber optical transmission network
Rtmaad系統綜合應用了數字信號處理、地理信息系統、光時域反射測量和波分復用等技術，實現了光纜中斷故障的自動準確定位，同時將光纖系統傳輸站的光端設備和電源設備的監測融合到一起進行故障實時監測和診斷。
