"Guhangana cyane" ni bwo buryo bwiza bwo kuranga isoko ry'ibikoresho bya DWDM bya Optical Transport. Nubwo ari isoko rinini, rifite agaciro ka miliyari 15 z'amadolari, hari inganda zigera kuri 20 zikora sisitemu zitabira kugurisha ibikoresho bya DWDM kandi zigahatanira isoko cyane. Ibyo bivuzwe, 90 ku ijana by'isoko rifitwe n'abacuruzi barindwi gusa, 10 ku ijana bisigaye bigasigara ku bacuruzi basigaye, ndetse no mu bandi barindwi ba mbere, isoko rinini cyane—amanota 25 hagati y'umucuruzi munini n'umuto.
Ubunini bw'ikigo n'ishoramari ni ikintu cy'ingenzi gitandukanya isoko, aho mu bacuruzi bakomeye, hanze ya FiberHome, bose bashora imari mu guhuza ibice bihagaze ku ruhande rw'umurongo nka coherent DSP na optical front end. Bisa nkaho ntacyo bitwaye niba optical front end ishingiye kuri Silicon Photonics (SiPh) cyangwa Indium Phosphide (InP) nubwo abahanga mu nganda bakomeje kuganira kuri izi koranabuhanga zombi. Ikintu cy'ingenzi ni uko ikigo cyakoze ikoranabuhanga ritandukanya ibicuruzwa n'ibindi, rigagabanya ikiguzi cy'ibicuruzwa byacyo, kandi rigaha ikigo umwanya mwiza wo kugurisha. Byongeye kandi, kubera ko bisaba urwego runini n'umutungo (amafaranga, abantu, n'umutungo mu by'ubwenge) kugira ngo hatezwe imbere ibi bice, guhuza vertical bitera inzitizi ku binjiza bishya (ndetse n'abashaje).
Gusimbuza ibicuruzwa birahari
Kimwe n’inganda nyinshi, imbaraga zo hanze mu nganda zikora ibijyanye no gutwara abantu ni ugusimbuza ibicuruzwa. Nubwo gusimbuza ibicuruzwa bitari ikibazo gikomeye mu myaka yashize, bitewe n’inyungu zigaragara mu mikorere n’ikiguzi cy’ikoranabuhanga rya DWDM hamwe n’imbogamizi zo gushyiramo ikoranabuhanga rya DWDM mu buryo bw’ikoranabuhanga riri hafi, ikirere gitangiye kuzamuka gato hamwe n’ibikoresho bito bya 400ZR bishobora gusimbuza. Kubera izi optique nshya zishobora gusimbuza mu buryo bwa QSFP-DD bishobora kohereza uburebure bwa 400 Gbps kugeza kuri kilometero 120, turimo kwitega ko hari inyungu nyinshi muri IP-over-DWDM (IPoDWDM), ari na yo miterere ya sisitemu ikoresha optique ya DWDM muri Ethernet Switch cyangwa Router. Ibi, nta kurobanura, bizongera urwego rw’irushanwa mu bikoresho bya DWDM mu gihe abakiriya bahitamo gukoresha sisitemu isanzwe ya DWDM iturutse ku bacuruzi bacu 20 ba DWDM cyangwa sisitemu ya IPoDWDM iturutse ku bandi bacuruzi bahinduranya. (Abacuruzi bakomeye ba Ethernet Switch na Router barimo Arista, Cisco, Juniper, na Nokia).
Icyakora, 400ZR izagirira akamaro abacuruzi ba DWDM ba optique. Impamvu imwe ni uko atari ko abakora bose bazifuza guhindura umuyoboro wabo bakajya kuri IPoDWDM kandi bazahitamo gukoresha optique ya 400ZR ikoreshwa kuri sisitemu ya DWDM, bigatuma imiterere y'umuyoboro ihinduka gato mu gihe bazungukira ku giciro gito cya optique ya 400ZR. Ariko indi mpamvu ni uko 400ZR ari ikoranabuhanga rihamye, bityo amasosiyete yashoye imari muri iri koranabuhanga mu myaka icumi ishize afite umwanya mwiza wo guhangana n'aya mahirwe mashya. Bityo, abakora optique ya 400ZR ikoreshwa muri optique ahanini bagizwe n'amasosiyete afite amateka maremare mu iterambere rya sisitemu za DWDM zikorana, nka Ciena, Cisco, na Nokia. Huawei yateganyaga kandi gukora 400ZR, ariko ntituzi neza niba amategeko ya Amerika kuri iyi sosiyete azadindiza iki gikorwa.
Abakiriya bakunda abatanga serivisi bo mu gace batuyemo iyo babonetse
Mu buryo bumwe na bumwe ibi si ibya kera cyangwa bishya, ariko ni ngombwa kongera kuvuga ko muri rusange abakiriya bakunda kugura ibikoresho ku mucuruzi wo mu gace. Muri iyi mbonerahamwe, isoko ry’ibikoresho bya DWDM ku isi rigabanyijemo ibice bikomeye n’abacuruzi batanga ibicuruzwa mu karere runaka. Ingano y’agasanduku igaragaza umugabane w’umucuruzi muri ako karere, kandi udusanduku tw’icyatsi kibisi ni abacuruzi bafatwa nk’abo mu gace k’iwabo. Ntibitangaje kuba mu turere tubiri—Amerika ya Ruguru n’Ubushinwa—aho hari umubare munini w’abacuruzi bo mu gihugu, umubare munini w’ibicuruzwa bya DWDM bigurishwa muri ayo masosiyete yo mu gihugu. Bitewe n’uruvange rw’amasosiyete menshi mu “andi,” sinashyize igicucu muri ayo masanduku, ariko muri Amerika ya Ruguru no mu Bushinwa, abenshi mu “andi” ni sosiyete zo mu gihugu.
Igishimishije ni udusanduku tudafite igicucu. Impamvu ni uko nyuma y’uko Amerika ishyizeho amategeko kuri ZTE mu 2018 na vuba aha Huawei, abatanga serivisi mu turere dufite umubare munini w’udusanduku tudafite igicucu (abacuruzi batari abo mu rugo) barushaho guhangayikishwa n’itangwa ry’ibikoresho. Kubera iyo mpamvu, abatanga serivisi bashaka kugabanya ibyago mu kugabanya kwishingikiriza ku mucuruzi umwe ndetse no kongera kwita ku batanga serivisi bo mu gace. Mu buryo bwinshi, ibi bizaba byiza ku bigo bito bikorera mu turere nka Tejas mu Buhinde, Padtec muri CALA, na PacketLight muri EMEA. Ariko, mu rwego rwo kugabanya ibyago, abatanga serivisi banini bazakomeza kugura ibikoresho byinshi ku nganda nini za DWDM zifite ubunini n’ikoranabuhanga rizifasha mu bikorwa byazo by’ejo hazaza.
Imiterere y'Inganda Ihindagurika
Ahari uburyo bwiza bwo gusobanura imiterere y’inganda z’ibikoresho bya WDM by’amashanyarazi muri uyu mwaka ni “ihindagurika.” Ibi ndabivuga kuko bitandukanye n’igihe cyashize aho imbaraga z’inganda zari zimwe uko umwaka utashye, imbaraga nshya zavutse mu nganda z’amashanyarazi muri uyu mwaka zishobora kuzihindura mu buryo buhindagurika. By’umwihariko, imbaraga nshya ndimo kuvuga ni ubushobozi bwo gusimbuza ibicuruzwa na IPoDWDM hakoreshejwe 400ZR muri QSFP-DD plug hamwe n’impinduka mu myitwarire y’abakiriya yatewe n’ibikorwa bya guverinoma ya Amerika ku nganda z’Abashinwa bishobora guhindura imiterere y’abagurisha mu turere tumwe na tumwe uko igihe kigenda gihita.
