"Kurushanwa cyane" nuburyo bwiza bwo kuranga ibikoresho bya Optical Transport DWDM isoko ryibikoresho.Nubwo ari isoko rinini, ripima miliyari 15 z'amadolari, hari abakora sisitemu zigera kuri 20 bitabira cyane kugurisha ibikoresho bya DWDM kandi bagaharanira kugabana isoko.Ibyo byavuzwe, 90 ku ijana by'isoko rifatwa n'abacuruzi barindwi gusa, hasigara 10 ku ijana ku bacuruzi basigaye, ndetse no muri barindwi ba mbere, delta yo ku isoko ni nini - amanota 25 ku ijana hagati y'abacuruzi benshi kandi bato.
Igipimo cyisosiyete nishoramari nikintu cyingenzi gitandukanya bigaragara ko igabanya isoko, aho mubacuruzi bo hejuru, hanze ya FiberHome, bose bashora imari muburyo bwo guhuza ibice kumurongo ugizwe na DSP hamwe na optique imbere.Ntabwo bisa nkaho bitwaye niba amaherezo ya optique ashingiye kuri Silicon Photonics (SiPh) cyangwa Indium Phosphide (InP) nubwo abahanga mu nganda bakomeje kujya impaka kuri tekinoloji zombi.Ikintu gifata umwanzuro nuko isosiyete yateje imbere ikoranabuhanga mu rugo ritandukanya ibicuruzwa n’abandi, rigabanya ibiciro by’ibicuruzwa, kandi bigaha isosiyete igihe cyiza cyo kwisoko.Byongeye kandi, kubera ko bisaba igipimo kinini nubutunzi (amafaranga, abantu, numutungo wubwenge) kugirango utezimbere ibyo bice, guhuza vertical bitera inzitizi kubinjira bashya (ndetse nabakera).
Gusimbuza ibicuruzwa birahari
Kimwe ninganda nyinshi, imbaraga ziva mubikorwa bya Optical Transport ninganda zo gusimbuza ibicuruzwa.Mugihe gusimbuza ibicuruzwa bitari iterabwoba nyaryo mumyaka mirongo ishize, kubera inyungu zisanzwe mumikorere nigiciro cyikoranabuhanga rya DWDM hamwe nimbogamizi kurwego rwa sisitemu yo kwinjiza ikoranabuhanga rya DWDM kurubuga rwegeranye, umuraba utangiye guhinduka gato hamwe ibintu bito 400ZR byoroshye optique.Nkibisubizo byibi bikoresho bishya byogushobora gukoreshwa muburyo bwa QSFP-DD bushobora kohereza 400 Gbps yumurambararo wa kilometero zigera kuri 120, turateganya ko inyungu ziyongera muri IP-hejuru ya DWDM (IPoDWDM), nuburyo bwububiko bwa sisitemu irimo DWDM optique muri Ethernet Hindura cyangwa Router.Ibi, ntavuze, byongera urwego rwamarushanwa mumwanya wibikoresho bya DWDM mugihe abakiriya bahitamo hagati yo gukoresha sisitemu gakondo ya DWDM kubacuruzi bacu 20 ba DWDM cyangwa sisitemu ya IPoDWDM kubandi bacuruzi bahinduranya.(Hejuru ya Ethernet Guhindura no kugurisha Router harimo Arista, Cisco, Juniper, na Nokia).
Ariko, 400ZR nayo izagirira akamaro abacuruzi ba optique ya DWDM.Impamvu imwe nuko abakora bose batazifuza guhindura umuyoboro wabo kuri IPoDWDM kandi bagahitamo gukoresha optique ya 400ZR ya optique kuri sisitemu ya DWDM, bigatuma imiterere y'urusobekerane ridahinduka mugihe bungukirwa nigiciro gito cya 400ZR optique.Ariko indi mpamvu nuko 400ZR ari tekinoroji ihuje bityo rero ibigo byashora imari muri iri koranabuhanga mumyaka icumi ishize bihagaze neza kugirango bikemure aya mahirwe mashya.Kubwibyo, abakora 400ZR yamashanyarazi optique igizwe ahanini namasosiyete afite amateka maremare mugutezimbere sisitemu ya DWDM ihuje, nka Ciena, Cisco, na Nokia.Huawei yari ifite intego yo guteza imbere 400ZR, ariko ntituzi neza niba Amerika ibuza iyi sosiyete izadindiza iki gikorwa.
Abakiriya bakunda abaguzi baho iyo baboneka
Muburyo bumwe ibi ntabwo bishaje cyangwa bishya, ariko ni ngombwa kongera gushimangira ko muri rusange abakiriya bahitamo kugura ibikoresho kubatanga isoko.Muri iyi mbonerahamwe, isoko ry’ibikoresho bya DWDM ku isi bigabanijwe mu turere twinshi n’abacuruzi batanga mu karere runaka.Ingano yagasanduku yerekana umugurisha mugabane muri kariya karere, kandi agasanduku k'icyatsi kibisi ni abacuruzi bafatwa nk'imbere mu karere.Ntabwo bitangaje kuba mu turere twombi - Amerika y'Amajyaruguru n'Ubushinwa - ahari umubare munini w'abacuruzi bo mu gihugu, umubare munini w'igurisha rya DWDM ujya muri ibyo bigo byo mu gihugu.Bitewe no kuvanga kwinshi kwamasosiyete muri "bandi," ntabwo nigeze ntwikira ayo masanduku, ariko muri Amerika ya ruguru no mu Bushinwa benshi mu "bandi" ni amasosiyete yo mu gihugu.
Igishobora gushimisha ni agasanduku katagira igicucu.Impamvu nuko nyuma yuko Amerika ishyizeho ibihano kuri ZTE muri 2018 na Huawei iherutse, abatanga serivise mukarere bafite umubare munini wibisanduku bitagira igicucu (abadandaza bo murugo) barushijeho guhangayikishwa no gutanga ibikoresho.Nkigisubizo, abatanga serivise barashaka guhura ningaruka mukugabanya kwishingikiriza kumuntu uwo ari we wese kimwe no kongera ibitekerezo byabatanga isoko.Muburyo bwinshi, ibi bizaba byiza kubigo bito bishingiye mu turere twaho nka Tejas mu Buhinde, Padtec muri CALA, na PacketLight muri EMEA.Ariko, murwego rwo kugabanya ingaruka, abatanga serivise nini birashoboka ko bazakomeza kugura ibikoresho byinshi mubakora inganda nini za DWDM bafite igipimo nikoranabuhanga kugirango bashyigikire ibikorwa byabo biri imbere.
Imiterere yinganda
Ahari inzira nziza yo gusobanura uko inganda za optique za WDM zikoreshwa muri uyu mwaka ari "imbaraga."Ibi ndabivuze kuberako bitandukanye no mubihe byashize igihe ingufu zinganda zari zimeze nkumwaka ku mwaka, imbaraga nshya zagaragaye mu nganda za optique muri uyu mwaka zishobora kuzihindura.By'umwihariko, imbaraga nshya mvuze ni imbaraga zishoboka zo gusimbuza ibicuruzwa hamwe na IPoDWDM ishobozwa na 400ZR mu cyuma cya QSFP-DD no guhindura imyitwarire y'abakiriya yatewe n'ibikorwa bya leta zunze ubumwe za Amerika ku bakora inganda z'Abashinwa zishobora guhindura imiterere y'abacuruzi mu turere tumwe na tumwe. igihe.
