Optical transmission ndiyo tekinoroji yekufambisa nenzira yezviratidzo zvemaziso pakati peanotumira neanogamuchira.Optical transmission equipment ndeye kushandura zvakasiyana-siyana zvezviratidzo kuita zviratidzo zvemaziso mune optical fiber transmission equipment, saka zvemazuva ano optical transmission equipment zvinowanzo shandiswa mu optical fiber.Inowanzo shandiswa optical transceiver midziyo ndeye: optical transceiver, optical MODEM, optical transceiver, optical switch, PDH, SDH, PTN uye mamwe marudzi emidziyo.
Inoenderana optical transmission tekinoroji sumo pfupi
Synchronous Optical Network (SONET) uye Synchronous Digital Hierarchy (SDH) : A fiber optic transmission system (yaimbova chiyero cheAmerica chinoshandiswa muNorth America, iyo yekupedzisira ndeyepasi rose).Zvinotora iyo synchronous transmission module (STM-1,155Mbps) seyakanyanya pfungwa.Iyo module inoumbwa net net information load, chikamu chepamusoro, uye manejimendi unit pointer.Hunhu hwayo hwakakurumbira hunoenderana neakasiyana PDH system.
Plesiochronous Digital Hierarchy (PDH) : Pre-SONET / SDH digital transmission system, isiri-optical transmission mainstream equipment.Inonyanya kugadzirirwa kutaurirana kwezwi.Iko hakuna yepasirese yakajairwa dhijitari chiratidzo chechiyero uye chimiro chechimiro, uye kubatana kwenyika dzese kwakaoma.
Wavelength Division Multiplex (WDM) : Chaizvoizvo, Frequency Division Multiplex (FDM) inoshandiswa pane optical fibers, kureva, FDM tekinoroji mune optical domain.Iyo inzira inoshanda yekuvandudza kugona kwe optical fiber kutaurirana.Kuti ushandise zvizere zviwanikwa zvakakura zvebhanwidth munzvimbo yakaderera-kurasikirwa kwe single-mode fiber, iyo yakaderera-kurasikirwa hwindo refiber rakakamurwa kuita nzira dzinoverengeka zvichienderana neyakasiyana frequency (kana wavelength) yega yega chiteshi.Ivo vanofambisa mameseji avo pane akasiyana wavelengths, saka havakanganise kune mumwe nemumwe kunyangwe pane imwechete fiber.Dense Wavelength Division Multiplex (DWDM) : Kusiyana nemaitiro eWDM akajairwa, masisitimu eDWDM ane nzvimbo yakamanikana yechiteshi uye zviri nani bandwidth kushandiswa.
Optical Add/Drop Multiplex (OADM) : Chishandiso chinoshandisa optical sefa kana splitter kuisa kana kupatsanura masaini masaini kubva kune wavelength division multiplexing transmission link.OADM ine optical wavelength masaini muWDM system yekusarudza iyo iri pamusoro / pazasi inodiwa chiyero, fomati uye protocol mhando.Chete chiratidzo chinodiwa chewavelength chinobatwa / kuisirwa pane node, uye mamwe masaini ewavelength anobuda pachena kuburikidza node.Dynamic (inochinjika, inogadzirika kana kurongeka) OADM ndiyo hwaro hwekuzadzikiswa kwemetropolitan optical network.Uchishandisa simba reOADM muinter-local optical ring ring network, iyo system inogona kupa yakazara wavelength chiteshi chekubatanidza pakati pechero node mbiri.
Optical cross interconnection (OpticalCross-connect, OXC): Zvishandiso zvinoshandiswa kune optical fiber network node, kuburikidza nemuchinjiko wekubatanidza masaini masaini, inzira yakakosha yekuwana yakavimbika network kuchengetedza / kudzoreredza uye otomatiki wiring nekutarisa.Iyo inonyanya kuumbwa neWDM tekinoroji uye optical air separation tekinoroji (optical switch).
All Optical Network (AON) : inoreva network network umo chiratidzo chinongopinda magetsi / optical uye optical / magetsi shanduko kana ichipinda uye ichisiya network, uye inogara iripo muchimiro chechiedza mukufambisira uye kuchinjana mune network.Mune mamwe mazwi, ruzivo runogara rwuri mu optical domain panguva yekufambisa kwayo kubva kune sosi node kuenda kunzvimbo yekuenda, uye wavelength inova iyo inonyanya kukosha unit yeall-optical network.Iyo yese-optical network iri pachena kune iyo chiratidzo nekuti yese yekufambisa yechiratidzo inoitwa mune yekuona domain.Iyo all-optical network inoziva nzira kuburikidza newavelength yekusarudza mudziyo.All-optical network yave sarudzo yekutanga yechizvarwa chinotevera high-speed (ultra-high-speed) broadband network nekuda kwekujeka kwayo kwakanaka, wavelength routing maitiro, kuenderana uye scalability.
Li-Fi: Iyi tekinoroji yekukurukurirana tekinoroji inoshandisa maLED-based indoor light waves panzvimbo yemasaisai eredhiyo ekufambisira data.Uye zvikwata zvepamusoro mukutsvagisa kweLi-Fi zviri kutarisa kupfuura maledhi ekufambisa data, iri laser-based Li-Fi yekutaurirana tekinoroji, iyo inogona kufungidzira kuvandudza mwero weLi-Fi pamusoro peLED kanopfuura kagumi.(Kutaura zvazviri, makore mashomanana adarika, kutapurirana kwepasi pemvura kwakagadzirwa neChina Huako, United States neIran kwakakwanisa kuwedzera tambo isina waya kusvika ku300Gb / s pa 1 mita kure. Iyo inoshandiswa imhepo.)
Izvo zviri pamusoro apa ishumo pfupi yeruzivo rwekutanga rwekutapurirana kwemaziso.Ndinotenda kuti wanzwisisa chinonzi optical transmission tekinoroji kuburikidza netsananguro pfupi iri pamusoro.Shenzhen HDV Phoelectron Technology LTD inogadzira inyanzvi mumidziyo yekutaurirana yemaziso sezvigadzirwa zvikuru.Kuti ipe zvirinani sevhisi kune vatengi vedu, yakashongedzerwa yakasimba uye yakanakisa R & D tekinoroji timu.Zvigadzirwa zvikuru zvekambani ndezveOLTONU/ ACONU/ kutaurirana optical module/kutaurirana optical module/OLTmidziyo / Ethernet chinja uye zvichingodaro, kupa hukama masevhisi kune akasiyana siyana zvinodiwa nevatengi, gamuchira kuvapo kwako.
