"Ukukhuphisana kakhulu" yindlela efanelekileyo yokubonakalisa imakethe yezixhobo ze-Optical Transport DWDM.Ngelixa iyimalike enkulu, enobunzima be-15 yeebhiliyoni zeerandi, kukho malunga nama-20 abenzi beenkqubo abathatha inxaxheba ekuthengiseni izixhobo ze-DWDM kwaye balwela ukwabelana ngemarike.Oko kwathiwa, i-90 yepesenti yeemarike ibanjwe ngabathengisi abasixhenxe kuphela, ishiya i-10 ekhulwini kubathengisi abaseleyo, kwaye naphakathi kwezisixhenxe eziphezulu, i-delta ye-market share share inkulu-ipesenti ze-25 phakathi komthengisi omkhulu kunye nomncinci.
Isikali senkampani kunye notyalo-mali ngumahluko ophambili obonakala ehlula imarike, apho phakathi kwabathengisi abaphezulu, ngaphandle kweFiberHome, bonke batyale imali ekudityanisweni ngokuthe nkqo kumacandelo ecala lomgca njenge-DSP ehambelanayo kunye nesiphelo sangaphambili se-optical.Akubonakali kungakhathali nokuba isiphelo sangaphambili se-optical sisekwe kwi-Silicon Photonics (SiPh) okanye i-Indium Phosphide (InP) nangona iingcali zeshishini ziqhubeka nokuxoxa ngobuchwephesha bumbini.Into ethatha isigqibo kukuba inkampani iphuhlise itekhnoloji yangaphakathi eyahlula imveliso kwabanye, yehlisa iindleko zemveliso, kwaye inika inkampani ixesha elingcono lokuthengisa.Ngaphaya koko, kuba kuthatha umlinganiselo omkhulu kunye nezibonelelo (imali, abantu, kunye nepropathi enomgangatho ophezulu wokuqonda) ukuphuhlisa la macandelo, ukudityaniswa ngokuthe nkqo kudala umqobo kubangeneli abatsha (kunye nabadala).
Ukutshintshwa kweMveliso kuyafumaneka
Njengoninzi lwemizi-mveliso, amandla angaphandle kwishishini lezoThutho lwe-Optical kukutshintsha imveliso.Ngelixa ukutshintshwa kwemveliso kwakungeyongozi yokwenyani kumashumi eminyaka adlulileyo, ngenxa yeenzuzo zendalo ekusebenzeni kunye neendleko zetekhnoloji ye-DWDM kunye nezithintelo zenqanaba lenkqubo yokubandakanya itekhnoloji ye-DWDM kwiqonga elikufutshane, umsinga uqalisa ukujika kancinci nge. ifom encinci ye-400ZR i-pluggable optics.Njengomphumo wolu lutsha oluxutywayo optics kwi-QSFP-DD ifom yefom enokuhambisa i-400 Gbps wavelengths ukuya kwiikhilomitha ze-120, silindele umdla okhulayo kwi-IP-over-DWDM (IPoDWDM), eyinkqubo yokwakhiwa kwenkqubo ebandakanya i-DWDM. optics kwi-Ethernet Tshintsha okanye Router.Oku kuya, ngaphandle kokuthetha, ukwandisa izinga lokukhuphisana kwindawo yezixhobo ze-DWDM njengoko abathengi banquma phakathi kokusebenzisa inkqubo ye-DWDM yendabuko evela kubathengisi bethu be-DWDM be-20 okanye inkqubo ye-IPoDWDM evela kwabanye abathengisi abatshintshayo.(Abathengisi be-Ethernet abaphezulu kunye ne-Router baquka i-Arista, i-Cisco, iJuniper, kunye ne-Nokia).
Nangona kunjalo, i-400ZR iya kuxhamla nabathengisi be-DWDM be-optical.Esinye isizathu kukuba akubona bonke abaqhubi abaya kufuna ukutshintsha inethiwekhi yabo kwi-IPoDWDM kwaye baya kukhetha ukusebenzisa i-400ZR i-pluggable optics kwi-DWDM system, ukugcina i-architecture yenethiwekhi ngandlela-thile ingatshintshi ngelixa bexhamla kwiindleko eziphantsi ze-400ZR optics.Kodwa esinye isizathu kukuba i-400ZR iteknoloji ehambelanayo kwaye ngoko ke iinkampani ezityale imali kule teknoloji kwiminyaka elishumi edlulileyo zilungele ukujongana neli thuba elitsha.Ke, abavelisi be-400ZR i-pluggable optics ikakhulu iqulethwe ziinkampani ezinembali ende ekuphuhliseni iinkqubo ze-DWDM ezihambelanayo, njengeCiena, Cisco, kunye neNokia.UHuawei ujonge ukuphuhlisa i-400ZR ngokunjalo, kodwa asiqinisekanga malunga nokuba izithintelo zase-US kwinkampani ziyakulibazisa na lo mzamo.
Abathengi bakhetha ababoneleli bengingqi xa befumaneka
Ngandlel’ ithile oku akukudalanga kutsha, kodwa kubalulekile ukuphinda-phinda ukuba abathengi ngokubanzi bakhetha ukuthenga izixhobo kumthengisi wendawo.Kule tshathi, imarike yezixhobo ze-DWDM yehlabathi inqunyulwe kwimimandla emikhulu kunye nabathengisi ababonelela kwindawo ethile.Ubungakanani bebhokisi bubonisa isabelo somthengisi kuloo mmandla, kwaye iibhokisi ezinomthunzi oluhlaza ngabathengisi abagqalwa njengekhaya kuloo mmandla.Akumangalisi ukuba kwimimandla emibini-eNyakatho Melika kunye neChina-apho kukho inani elikhulu labathengisi basekhaya, ubuninzi beentengiso ze-DWDM ziya kwezi nkampani zasekhaya.Ngenxa yomxube ophezulu weenkampani "kwabanye," andizange ndifake umthunzi ezo bhokisi, kodwa kuMntla Melika naseTshayina uninzi "lwezinye" ziinkampani zasekhaya ngokunjalo.
Yintoni enokuba nomdla kwiibhokisi ezingenamthunzi.Isizathu kukuba emva kokuba i-US ibeke izithintelo kwi-ZTE kwi-2018 kwaye kutshanje iHuawei, ababoneleli ngenkonzo kwimimandla enenani elikhulu leebhokisi ezingenamthunzi (abathengisi abangekho basekhaya) baxhalabile ngokubonelelwa kwezixhobo.Ngenxa yoko, ababoneleli-nkonzo bajonge ukukhupha umngcipheko ngokunciphisa ukuxhomekeka kuye nawuphi na umniki-nkonzo omnye kunye nokwandisa ukuqwalaselwa kwababoneleli bendawo.Ngeendlela ezininzi, oku kuya kuba kuhle kwiinkampani ezincinci ezisekelwe kwimimandla yendawo efana neTejas eIndiya, iPadtec eCALA, kunye nePacketLight kwi-EMEA.Nangona kunjalo, kwi-vein yokunciphisa umngcipheko, abona baboneleli-nkonzo bakhulu baya kuqhubeka nokuthenga izixhobo ezininzi kubavelisi abakhulu be-DWDM abanomlinganiselo kunye nobuchwepheshe bokuxhasa iinzame zabo zexesha elizayo.
Imo yeShishini
Mhlawumbi eyona ndlela ibalaseleyo yokuchaza imeko yoshishino lwezixhobo ze-WDM kulo nyaka “luguquguqukayo.”Ndithetha oku kuba ngokungafaniyo nangaphambili xa amandla oshishino ayefana unyaka nonyaka, kwavela amandla amatsha kushishino lwamehlo kulo nyaka olunokuthi luyimise kwakhona.Ngokukodwa, amandla amatsha endibhekisa kuwo kukusebenza okuphezulu kokutshintshwa kwemveliso nge-IPoDWDM enikwe amandla yi-400ZR kwiplagi ye-QSFP-DD kunye notshintsho kwindlela yokuziphatha yabathengi eyenziwe zizenzo zikaRhulumente wase-US kubavelisi baseTshayina abanokuguqula indawo yomthengisi kwimimandla ethile. ixesha elidlulele.
