先前技術如圖1之OTDR光纖有線電視網路監控系統與圖2之Cheetah 光纖有線電視監控系統。 OTDR光纖有線電視網路監控系統,係將〇TDR 1〇1置於頭端機房作 為監控光彳5號,OTDR 101本身雷射光源波長為1310 nm或1650 nm。而 載有有線電視多頻道訊號105的載波光信號(波長1550nm),由有線電視類 比發射機即光發射機104 (Optical Transmitter)發出,利用13HV1550或 1550/1650分波多工器102 (WDM MUX)將光發射機104的載波光信號經 光放大器103(Erbium-Doped Fiber Amplifier, EDFA)與監控光信號經由標準 單模光纖106 (Single Mode Fiber,SMF)傳送出去,在光投落點處使用 1310/1550 或 1550/1650 分波解多工器 110 (w〇M DEMUX)將 1550 nm 波長的光信號濾出,最後再利用光接收機107 (〇pticai Receiver)將光信號轉 換成射頻(RF)信號並由使用者1〇8接收。〇tdr ιοί所打出的光信號在分 波解多工器110處會反射回到頭端為OTDR 101所接收,藉由〇tdR 101 所呈現的結果如圖6a與圖6b,可判斷光纖網路是否有斷線的問題。〇TDR 101在使用時’所產生的雷射光波長和傳遞訊號的光波長相近,會對信號波 長產生干擾,造成視訊品質的劣化,所以無法24小時的連續監控,只能不 定時的抽測監控光纖網路是否正常運作。The prior art is shown in Figure 1 for the OTDR fiber-optic cable network monitoring system and Figure 2 for the Cheetah fiber-optic cable monitoring system. The OTDR fiber-optic cable TV network monitoring system places the 〇TDR 1〇1 in the head-end room as the monitoring diaphragm No. 5, and the OTDR 101 itself has a laser source wavelength of 1310 nm or 1650 nm. The carrier optical signal (wavelength 1550 nm) carrying the cable multi-channel signal 105 is sent by a cable analog transmitter, Optical Transmitter 104, using a 13HV1550 or 1550/1650 splitter multiplexer 102 (WDM MUX). The carrier optical signal of the optical transmitter 104 is transmitted through an optical amplifier 103 (Erbium-Doped Fiber Amplifier, EDFA) and a monitor optical signal via a standard single mode fiber (SMF), and 1310 is used at the light drop point. The /1550 or 1550/1650 demultiplexer 110 (w〇M DEMUX) filters out the 1550 nm wavelength optical signal and finally uses the optical receiver 107 (〇pticai Receiver) to convert the optical signal into radio frequency (RF). The signal is received by the user 1〇8. The optical signal emitted by 〇tdr ιοί will be reflected back to the head end of the multiplexer 110 for reception by the OTDR 101. The result presented by 〇tdR 101 can be judged as shown in Fig. 6a and Fig. 6b. Is there a problem with disconnection? 〇TDR 101 uses a laser light wavelength that is similar to the wavelength of the transmitted signal when it is used. It interferes with the signal wavelength, causing deterioration of video quality. Therefore, it cannot monitor continuously for 24 hours, and can only monitor the fiber without timing. Is the network working properly?

In addition, a response 1355813 209 (Transponder) is installed at the position of the light drop point to be monitored, and the most important The point is that the network itself must be a two-way network system to have a solution _ light drop response ^ (four) control signal. The signal monitored by the network normal router 209 is transmitted back to the head end by the uplink signal (5~3〇MHz). If the receiver 2G2 can pick up the uplink backhaul signal, the wire shows normal operation. When the fiber network is disconnected, the headend response receiver 2G2 does not receive the far-end transponder 2G9, which means the single-mode fiber. 21〇After the broken or monitored light drop point has a problem...
