[Sumo] Iyo wavelength division multiplexing tekinoroji inogona kushandisa zvizere iyo hombe bandwidth zviwanikwa zvinounzwa nenzvimbo yakaderera-yarasikirwa ye single-modhi fiber. Zvinoenderana ne frequency (kana wavelength) yemwenje wave yegwaro rega rega, patsanura yakaderera-kurasikirwa hwindo refiber mumatanho akati wandei, shandisa mwenje wave semutakuri wechiratidzo, uye shandisa wavelength division multiplexer (multiplexer) pa kuguma kwekutumira.
Iyo wavelength division multiplexing tekinoroji inogona kushandisa zvizere iyo yakakura bandwidth zviwanikwa zvinounzwa nenzvimbo yakaderera-yarasikirwa yeimwe-modhi fiber. Zvinoenderana ne frequency (kana wavelength) yemwenje wave yegwaro rega rega, iyo yakaderera-kurasikirwa hwindo re optical fiber rakakamurwa kuita nzira dzinoverengeka, mwenje wave unoshandiswa semutakuri wechiratidzo, uye wavelength division multiplexer (multiplexer). ) inoshandiswa pakupera kwekutumira. Iwo masignal optical carriers ewavelengths anosanganiswa uye anotumirwa mune optical fiber yekutapurirana. Pakupera kwekugamuchira, wavelength division multiplexer (wave splitter) inoparadzanisa aya anotakura anotakura anotakura masaini akasiyana pawavelengths akasiyana. Sezvo zviratidzo zvinotakura zvinotakura zvakasiyana-siyana zvinogona kuonekwa sekuzvimiririra kune mumwe nemumwe (pasina kufunga nezvekusagadzikana kwefiber optical), multiplexing uye kutumira zviratidzo zvakawanda zvemaziso zvinogona kuonekwa mune imwe optical fiber.
Fiber Access Technology
Iyo optical fiber yekuwana network ndiyo "yekupedzisira mamaira" yeruzivo nzira. Kuti uwane ruzivo rwekumhanya-mhanya uye kuzadzisa zvinodiwa neruzhinji, kwete chete Broadband backbone transmission network, asiwo chikamu chekuwana mushandisi ndicho kiyi. Optical fiber yekuwana network ndiyo yakakosha tekinoroji yekumhanya-mhanya kweruzivo muzviuru zvedzimba. MuOptical fiber Broadband access, nekuda kwenzvimbo dzakasiyana dzekusvika dzeOptical fibers, kune akasiyana maapplication akadai seFTTB, FTTC, FTTCab neFTTH, pamwe chete inonzi FTTx. Nokudaro, inogona kushandisa zvizere maitiro e-broadband of optical fibers, kupa vashandisi iyo inodiwa isingabvumirwi bandwidth, uye inosangana zvizere nezvinodiwa zvekusvika kwebroadband. Parizvino, tekinoroji yemumba inogona kupa vashandisi FE kana GE bandwidth, inova nzira yakanaka yekuwana yevashandisi vemabhizinesi makuru uye epakati.
Kuvandudzwa kweOptical Fiber Communication Technology
Mumakore achangopfuura, nekufambira mberi kwetekinoroji, kuvandudzwa kweiyo telecommunication manejimendi system uye zvishoma nezvishoma kuvhurwa kuzere kwemusika wekufambiswa kwemashoko, kuvandudzwa kweoptical fiber communication kwakaratidza zvakare mamiriro matsva ekusimudzira kwakasimba. Iyi inotevera sumo pfupi kune huru budiriro hotspots mumunda we optical fiber kutaurirana. Tsanangudzo uye tarisiro, kukurudzirwa kwe-ultra-high-speed systems, kushanduka kune ultra-guru-capacity WDM systems.
Tichitarisa kubva mukusimudzirwa kwe optical fiber kutaurirana mumakore achangopfuura, kuvaka nyika backbone optical network iyo inonyanya kujeka, inoshanduka zvikuru uye yakakura-yakakura kukwanisa haigoni kuisa nheyo yakasimba yeramangwana National Information Infrastructure (NII), asi zvakare indasitiri yeruzivo rwenyika yangu muzana rinouya uye kusimuka kwehupfumi hwenyika uye chengetedzo yenyika zvine kukosha kwakanyanya kwehurongwa. Kuvandudzwa kweindasitiri optical fiber yekutaurirana inzira isingadzokerike yekutaurirana kwemazuva ano.
