Ukuhanjiswa kwe-Optical yitekhnoloji yokudlulisa ngendlela yeempawu ze-optical phakathi komthumeli kunye nomamkeli.Isixhobo sokuhambisa i-Optical kukuguqula imiqondiso eyahlukeneyo ibe yimiqondiso ye-optical kwisixhobo sokuhanjiswa kwefiber optical, ngoko ke izixhobo zanamhlanje zothumelo lwe-optical ziqhele ukusetyenziswa kwifiber optical.Izixhobo zokuhanjiswa kwe-optical eziqhelekileyo ezisetyenziswayo zezi: i-transceiver optical, i-MODEM ebonakalayo, i-transceiver optical, i-optical switch, i-PDH, i-SDH, i-PTN kunye nezinye iintlobo zezixhobo.
Intshayelelo emfutshane yetekhnoloji yosasazo olunxulumeneyo
I-Synchronous Optical Network (SONET) kunye ne-Synchronous Digital Hierarchy (SDH) : Inkqubo yokuhanjiswa kwe-fiber optic (yangaphambili ngumgangatho waseMelika osetyenziswa eNyakatho Melika, lo mva ngumgangatho wamazwe ngamazwe).Kuthatha imodyuli yokuhanjiswa kwe-synchronous (STM-1,155Mbps) njengengcamango esisiseko.Imodyuli yenziwe ngumthwalo wolwazi olushiyekileyo, umphezulu wecandelo, kunye nesalathisi seyunithi yolawulo.Isici sayo esibalaseleyo siyahambelana nenkqubo eyahlukeneyo yePDH.
I-Plesiochronous Digital Hierarchy (PDH) : I-Pre-SONET / SDH inkqubo yokuhanjiswa kwedijithali, izixhobo eziqhelekileyo zokuhanjiswa kwe-non-optical.Ikakhulu yenzelwe ukunxibelelana ngelizwi.Akukho mgangatho wehlabathi jikelele wezinga lomqondiso wedijithali kunye nesakhiwo sesakhelo, kwaye uqhagamshelwano lwamazwe ngamazwe lunzima.
I-Wavelength Division Multiplex (WDM) : Ngokusisiseko, i-Frequency Division Multiplex (FDM) iphunyezwa kwiifibers optical, oko kukuthi, iteknoloji ye-FDM kwi-domain optical.Yindlela esebenzayo yokuphucula amandla onxibelelwano lwefiber optical.Ukuze kusetyenziswe ngokupheleleyo izibonelelo ezinkulu ze-bandwidth kwindawo ephantsi yelahleko ye-fiber-mode-mode, i-fiber ephantsi-ilahleko yefestile ihlulwe ibe ngamajelo amaninzi ngokwezahlulo ezahlukeneyo (okanye ubude be-wavelength) kwitshaneli nganye.Bathumela imiyalezo yabo kubude bamaza ahlukeneyo, ke ngoko abaphazamisi omnye komnye nakwifayibha enye.I-Dense Wavelength Division Multiplex (DWDM) : Ngokungafani neenkqubo ze-WDM eziqhelekileyo, iinkqubo ze-DWDM zinezithuba ezincinci kunye nokusetyenziswa kwe-bandwidth engcono.
I-Optical Add/drop Multiplex (OADM) : Isixhobo esisebenzisa isihluzo se-optical okanye i-splitter ukufaka okanye ukwahlula izibonakaliso ze-optical kwi-wavelength division multiplexing transmission link.I-OADM inemiqondiso ye-optical wavelength kwinkqubo ye-WDM ukukhetha ireyithi engentla / engezantsi efunekayo, ifomathi kunye nohlobo lweprotocol.Kuphela isignali yobude obufunekayo icofa / ifakwe kwindawo, kwaye ezinye iimpawu ze-wavelength zibonakala ngaphaya kwendawo.I-Dynamic (eguquguqukayo, ehlengahlengiswayo okanye enokucwangciswa) I-OADM sisiseko sofezekiso lothungelwano lwe-metropolitan optical network.Ukusebenzisa i-OADM eguquguqukayo kuthungelwano lwendandatho ye-optical ring, inkqubo inokubonelela ngokuqhagamshelwa kwe-wavelength channel epheleleyo phakathi kwazo naziphi na iindawo ezimbini.
I-Optical Cross interconnection (i-OpticalCross-connect, i-OXC): Izixhobo ezisetyenziselwa i-fiber network nodes, ngokusebenzisa uxhulumaniso olunqamlezayo lwezibonakaliso ze-optical, yindlela ebalulekileyo yokufezekisa ukukhuselwa kwenethiwekhi ethembekileyo / ukubuyisela kunye nocingo oluzenzekelayo kunye nokubeka iliso.Ikakhulu iqulunqwe iteknoloji ye-WDM kunye neteknoloji yokwahlukana komoya (i-optical switch).
Yonke iNethiwekhi ye-Optical (AON) : ibhekiselele kwinkqubo yenethiwekhi apho isignali idlula kuphela umbane / optical kunye nokuguqulwa kombane / umbane xa ingena kwaye ishiya inethiwekhi, kwaye ihlala ikhona ngendlela yokukhanya kwinkqubo yokudluliselwa kunye nokutshintshiselwa inethiwekhi.Ngamanye amazwi, ulwazi luhlala lukwi-domain ye-optical ngexesha lokudluliselwa kwi-node yomthombo ukuya kwindawo yokuya kuyo, kwaye i-wavelength iba yiyunithi esisiseko yenethiwekhi yonke ye-optical network.Inethiwekhi yonke ye-optical iyabonakala kwisignali kuba yonke i-signal transmission iqhutyelwa kwi-domain optical.Inethiwekhi ye-all-optical iqonda indlela kwisixhobo sokukhetha ubude be-wavelength.Inethiwekhi ye-Optical yonke ibe yinto yokuqala yokukhetha kwisizukulwana esilandelayo se-high-speed (i-ultra-high-speed) inethiwekhi ye-broadband ye-broadband ngenxa yokungafihli kakuhle kwayo, iimpawu zomzila we-wavelength, ukuhambelana kunye nokulinganisa.
I-Li-Fi: Le teknoloji yonxibelelwano yamehlo isebenzisa amaza okukhanya angaphakathi asekelwe kwi-LED endaweni yamaza erediyo ukusasaza idatha.Kwaye amaqela aphezulu kuphando lwe-Li-Fi ajonge ngaphaya kwee-leds zokuhanjiswa kwedatha, esekelwe kwi-laser-based Li-Fi iteknoloji yonxibelelwano, enokuthi iphucule izinga le-Li-Fi ngaphezu kwe-LED ngamaxesha angaphezu kwe-10.(Enyanisweni, kwiminyaka embalwa edlulileyo, ukuhanjiswa kwamanzi angaphantsi kwamanzi aphuhliswe yi-China Huako, i-United States kunye ne-Iran yakwazi ukunyusa izinga le-wireless ukuya kwi-300Gb / s kumgama weemitha ezili-1. I-medium esetyenziswayo ngumoya.)
Oku ngasentla sisingeniso esifutshane kulwazi olusisiseko losasazo lwamehlo.Ndiyakholelwa ukuba uyayiqonda into yokuba yintoni itekhnoloji yothumelo lokukhanya ngale ngcaciso imfutshane ingentla.I-Shenzhen HDV Phoelectron Technology LTD ngumvelisi okhethekileyo kwizixhobo zonxibelelwano zamehlo njengezona mveliso ziphambili.Ukuze kubonelelwe ngenkonzo ekumgangatho ongcono kubathengi bethu, ixhotyiswe ngeqela lobugcisa elinamandla neligqwesileyo le-R & D.Iimveliso eziphambili zenkampaniOLTI-ONU/ ACONU/ imodyuli yokubona yonxibelelwano/imodyuli yokubona yonxibelelwano/OLTizixhobo / Ethernet switch njalo njalo, ukubonelela ngeenkonzo ezihambelana neemfuno ezahlukeneyo zabathengi, bamkele ubukho bakho.
