"Kukwikwidzana zvikuru" ndiyo nzira yakanakisisa yekuratidza musika wemidziyo yeOptical Transport DWDM. Kunyange zvazvo iri musika mukuru, une huremu hwemadhora mabhiriyoni gumi nemashanu emadhora, kune vagadziri vemasisitimu vanosvika makumi maviri vanotora chikamu mukutengesa michina yeDWDM uye vanokwikwidzana nesimba kuti vawane mugove wemusika. Nekudaro, 90 muzana yemusika inobatwa nevatengesi vanomwe chete, zvichisiya 10 muzana kune vatengesi vasara, uye kunyangwe pakati pevanomwe vepamusoro, delta yemugove wemusika yakakura - 25 muzana pakati pemutengesi mukuru nemudiki.
Chiyero chekambani nekudyara mari ndicho chinhu chikuru chinosiyanisa musika, uko pakati pevatengesi vepamusoro, kunze kweFiberHome, vese vakaisa mari mukubatanidzwa kwemagetsi pazvikamu zvemagetsi zvakaita se coherent DSP uye optical front end. Hazviratidzike sezvine basa kana optical front end yakavakirwa paSilicon Photonics (SiPh) kana Indium Phosphide (InP) kunyangwe nyanzvi dzeindasitiri dzichiramba dzichikurukura nezve matekinoroji maviri aya. Chinhu chikuru ndechekuti kambani yakagadzira tekinoroji yemukati inosiyanisa zvigadzirwa kubva kune zvimwe, inoderedza mitengo yezvigadzirwa zvayo, uye inopa kambani nguva iri nani yekushambadzira. Uyezve, sezvo zvichitora huwandu hwakawanda uye zviwanikwa (mari, vanhu, uye pfuma yepfungwa) kugadzira zvikamu izvi, kubatanidzwa kwemagetsi kunopa chipingamupinyi kune vanotanga vatsva (uye kunyange vekare).
Kutsiva Chigadzirwa Kunowanikwa
Kufanana nemaindasitiri mazhinji, simba rekunze muindasitiri yeOptical Transport kutsiva chigadzirwa. Kunyange hazvo kutsiva chigadzirwa kwaisava njodzi chaiyo mumakumi emakore apfuura, nekuda kwekubatsira kuripo mukushanda uye mutengo wetekinoroji yeDWDM pamwe chete nemiganho yesystem-level pakuisa tekinoroji yeDWDM mupuratifomu iri pedyo, shanduko iri kutanga kuchinja zvishoma ne small form factor 400ZR pluggable optics. Nekuda kweaya ma pluggable optics matsva muQSFP-DD form factor inogona kutumira 400 Gbps wavelengths kusvika 120 kilometers, tiri kutarisira kufarira kuri kukura muIP-over-DWDM (IPoDWDM), inova system architecture inosanganisira DWDM optics muEthernet Switch kana Router. Izvi, pasina kutaura, zvichawedzera makwikwi munzvimbo yemidziyo yeDWDM sezvo vatengi vachisarudza pakati pekushandisa system yechinyakare yeDWDM kubva kuvatengesi vedu makumi maviri veDWDM kana IPoDWDM system kubva kune vamwe vatengesi veswitching. (Vatengesi vepamusoro veEthernet Switch neRouter vanosanganisira Arista, Cisco, Juniper, uye Nokia).
Zvisinei, 400ZR ichabatsirawo vatengesi veOptical DWDM. Chimwe chikonzero ndechekuti havasi vese vanozoda kuchinja network yavo kuita IPoDWDM uye vachasarudza kushandisa 400ZR pluggable optics paDWDM system, zvichiita kuti network isachinje asi vachibatsirwa nemutengo wakaderera we400ZR optics. Asi chimwe chikonzero ndechekuti 400ZR tekinoroji inoshanda zvakanaka uye saka makambani akadyara mari mu tekinoroji iyi mumakore gumi apfuura akagadzirirwa kugadzirisa mukana uyu mutsva. Saka, vagadziri ve400ZR pluggable optics vanowanzova makambani ane nhoroondo refu mukugadzirwa kwe coherent DWDM systems, dzakadai seCiena, Cisco, neNokia. Huawei aidawo kugadzira 400ZR, asi hatina chokwadi kana zvirambidzo zveUS pakambani zvichanonotsa basa iri.
Vatengi Vanosarudza Vatengesi Vemunharaunda Kana Varipo
Mune dzimwe nzira izvi hazvisi zvekare kana kuti zvitsva, asi zvakakosha kudzokorora kuti kazhinji vatengi vanosarudza kutenga michina kubva kumutengesi wemuno. Muchati iyi, musika wepasi rose wemidziyo yeDWDM wakakamurwa kuita matunhu makuru uye vatengesi vanopa munzvimbo yakatarwa. Hukuru hwebhokisi hunoratidza mugove wevatengesi munharaunda iyoyo, uye mabhokisi ane ruvara rwegirini ndivo vatengesi vanoonekwa sevemuno munharaunda iyoyo. Hazvishamisi kuti munzvimbo mbiri idzi—North America neChina—uko kune vatengesi vakawanda vemuno, huwandu hwakawanda hwekutengesa kweDWDM hunoenda kumakambani aya emuno. Nekuda kwekusanganiswa kukuru kwemakambani mu "mamwe," handina kuisa mumvuri mumabhokisi iwayo, asi muNorth America neChina ruzhinji rwe "mamwe" makambani emuno futi.
Chingangove chinonakidza mabhokisi asina mumvuri. Chikonzero ndechekuti mushure mekunge US yaisa zvirambidzo paZTE muna 2018 uye munguva pfupi yapfuura Huawei, vanopa masevhisi munzvimbo dzine mabhokisi akawanda asina mumvuri (vatengesi vasiri vemuno) vari kunetseka zvakanyanya nezvekuwanikwa kwemidziyo. Nekuda kweizvozvo, vanopa masevhisi vari kutsvaga kuderedza njodzi nekuderedza kuvimba nemutengesi mumwe chete pamwe nekuwedzera kufunga nezvevatengesi vemuno. Munzira dzakawanda, izvi zvichave zvakanaka kumakambani madiki ari munzvimbo dzemuno dzakadai seTejas muIndia, Padtec muCALA, uye PacketLight muEMEA. Zvisinei, mukuderedza njodzi, vanopa masevhisi makuru vangangoramba vachitenga michina yakawanda kubva kuvagadziri vakuru veDWDM vane hukuru uye tekinoroji yekutsigira mabasa avo eramangwana.
Mamiriro Ezvinhu Akachinja-chinja muIndasitiri
Pamwe nzira yakanakisa yekutsanangura mamiriro eindasitiri yemidziyo yeWDM ye optical gore rino ndeye "dynamic." Ndinotaura izvi nekuti kusiyana nekare apo masimba eindasitiri aive akafanana gore negore, masimba matsva akabuda muindasitiri ye optical gore rino anogona kuichinja-chinja. Kunyanya, masimba matsva andiri kutaura nezvawo kugona kwakanyanya kwekutsiva chigadzirwa neIPoDWDM inogoneswa ne400ZR muQSFP-DD plug uye shanduko muhunhu hwevatengi hwakagadzirwa nezviito zvehurumende yeUS pavagadziri vekuChina izvo zvinogona kuchinja mamiriro evatengesi mune dzimwe nzvimbo nekufamba kwenguva.
