APT kirasi diki - Ongororo pane Hunhu hweWDM Sisitimu uye Yayo Musika Kunyorera

1. shandisa zvizere bandwidth zviwanikwa zve optical fiber. Fiber ine yakakura bandwidth zviwanikwa (yakaderera kurasikirwa bhendi). Wavelength kupatsanura tekinoroji yekuwedzera tekinoroji inowedzera kugona kutapudza kwefibre kanoverengeka kusvika gumi kana nemazana kana zvakapetwa kupfuura iyo yeimwe wavelength, nokudaro ichiwedzera simba rekutapurirana kweiyo fiber uye ichideredza mutengo. Iyo ine hukuru hwekushandisa kukosha uye kukosha kwehupfumi.

2. chiratidzo pachena hutachiwana. Nekuti iyo WDM sisitimu yakawandisa uye demultiplexed zvinoenderana neyakasiyana wavelength yechiedza, haina chekuita nechiyero chechiratidzo uye nzira yemagetsi modulation, ndokuti, iyo data iri "pachena" kune iyo data. Nekuda kweizvozvo, masaini ane hunhu hwakasiyana zvachose anogona kutapuriranwa, senge ATM, SDH, IP uye kusanganisa kutapurirana kwemazhinji masevhisi (odhiyo, vhidhiyo, data, nezvimwewo), nezvimwe.

3. kuwedzera nekuvandudza zviri nyore uye zviri nyore, mutengo wakaderera Izvo zviri nyore kuwedzera kugona kweiyo optical fiber kutaurirana system nekushandisa wavelength kupatsanura multiplexer tekinoroji. Mukuita kwekuwedzera kwenetiweki uye kusimudzira, hapana chikonzero chekushandura iyo tambo tambo, asi chete kutsiva inoendesa transmitter uye optical receiver, inova yakanaka nzira yekuwedzera. Ndokumbira kuti uende kune webhusaiti yekambani kuti uwane ruzivo rwehunyanzvi: www.guangying.com /www.qdapt.com.
