Amagambo ahinnye: kongera ubushobozi bwa network optique, udushya mu ikoranabuhanga rihoraho, imishinga y'igerageza ya interface yihuta itangizwa buhoro buhoro
Muri iki gihe cy’ingufu za mudasobwa, hamwe n’imbaraga nyinshi za serivisi n’ibikorwa bishya, ikoranabuhanga ryo kunoza ubushobozi bw’ibipimo byinshi nk’igipimo cy’ibimenyetso, ubugari bwa spectral buhari, uburyo bwo gukwirakwiza amakuru menshi, n’ibitangazamakuru bishya byo kohereza amakuru bikomeje guhanga udushya no gutera imbere.
Mbere na mbere, ukurikije uko umurongo cyangwa umuyoboro w'amajwi wiyongera, igipimo cya10G PONGushyira mu bikorwa umuyoboro w’itumanaho byarushijeho kwaguka, amahame ya tekiniki ya 50G PON muri rusange yarahagaze, kandi ipiganwa ry’ibisubizo bya tekiniki bya 100G/200G PON ni rikomeye; umuyoboro w’itumanaho wiganjemo kwaguka k’umuvuduko wa 100G/200G, igipimo cy’umuvuduko w’itumanaho rya 400G imbere cyangwa hanze y’aho amakuru aherereye byitezwe kwiyongera cyane, mu gihe 800G/1.2T/1.6T n’ibindi bikorwa by’ikoranabuhanga bigezweho hamwe n’ubushakashatsi bugezweho bihuriweho, kandi abakora itumanaho ry’amajwi bo mu mahanga biteganijwe ko bazasohora ibikoresho bya 1.2T cyangwa byinshi bigezweho byo gutunganya DSP cyangwa gahunda z’iterambere rusange.
Icya kabiri, ukurikije uburyo bwo kohereza amakuru buhari, kwaguka buhoro buhoro k'umuyoboro wa C w'ubucuruzi kugera kuri C+L byabaye igisubizo cyo guhuza ibikorwa by'inganda. Biteganijwe ko imikorere yo kohereza amakuru muri laboratwari izakomeza gutera imbere muri uyu mwaka, kandi icyarimwe hagakomeza gukorwa ubushakashatsi ku miyoboro migari nka S+C+L.
Icya gatatu, ukurikije uburyo bwo gukwirakwiza ibimenyetso, ikoranabuhanga ryo gukwirakwiza ikirere rizakoreshwa nk'igisubizo cy'igihe kirekire ku mbogamizi z'ubushobozi bwo kohereza. Sisitemu y'insinga zo munsi y'amazi ishingiye ku kongera buhoro buhoro umubare w'imirongo ya fibre optique izakomeza gukoreshwa no kwaguka. Hashingiwe ku buryo bwo gukwirakwiza ibyuma byinshi cyangwa byinshi Ikoranabuhanga ryo gukwirakwiza ibyuma bikomeye rizakomeza kwigwa mu buryo bwimbitse, ryibanda ku kongera intera yo kohereza no kunoza imikorere yo kohereza.
Hanyuma, ukurikije ikoranabuhanga rishya ryo kohereza amakuru, fibre optique ya G.654E izaba amahitamo ya mbere ku muyoboro wa trunk no kongera imbaraga mu kohereza amakuru, kandi izakomeza kwiga ku bijyanye n'uburyo bwo kohereza amakuru mu buryo bwa multiplexing optique (insinga). Spectrum, gutinda guke, ingaruka nke zidasanzwe, gukwirakwira guke, n'izindi nyungu nyinshi byabaye intego y'inganda, mu gihe uburyo bwo kohereza amakuru no kuyakurura bwarushijeho kunozwa. Byongeye kandi, ukurikije ikoranabuhanga no kugenzura igihe ibicuruzwa bigeze, kwita ku iterambere ry'inganda, nibindi, abakora mu gihugu biteganijwe ko bazatangiza imiyoboro mishya ya sisitemu zihuta nka DP-QPSK 400G intera ndende, 50G PON ifite uburyo bubiri bwo kohereza amakuru hamwe n'ubushobozi bwo kohereza amakuru mu buryo bungana muri 2023. Umurimo wo kugenzura ikizamini urushaho kwemeza igihe ibicuruzwa bisanzwe bigeze ku gihe kandi ugashyiraho ishingiro ryo kohereza amakuru mu bucuruzi.
Amaherezo, hamwe no kunoza umuvuduko w’ikoranabuhanga mu gukwirakwiza amakuru n’ubushobozi bwo kuyahindura, gushyira hamwe cyane no kugabanya ikoreshwa ry’ingufu byabaye ibisabwa mu iterambere rya module y’ikoranabuhanga mu gice cy’ibanze cy’itumanaho ry’ikoranabuhanga, cyane cyane mu bihe bisanzwe byo gukoresha ikigo cy’itumanaho, iyo ubushobozi bwo kuyahindura bugeze kuri 51.2Tbit/s. Kandi hejuru yaho, uburyo bwo guhuza module z’ikoranabuhanga bufite umuvuduko wa 800Gbit/s no hejuru yayo bushobora guhura n’irushanwa ryo guhuza ikoranabuhanga rya paki y’amashanyarazi n’iy’amashanyarazi (CPO). Biteganijwe ko amasosiyete nka Intel, Broadcom, na Ranovus azakomeza kuvugurura muri uyu mwaka. Uretse ibicuruzwa n’ibisubizo bya CPO bihari, kandi ashobora gutangiza ubwoko bushya bw’ibicuruzwa, andi masosiyete y’ikoranabuhanga rya silicon photonics na yo azakurikirana ubushakashatsi n’iterambere cyangwa akabyitaho cyane.
Byongeye kandi, mu bijyanye n'ikoranabuhanga ryo guhuza imiterere y'amafoto rishingiye ku mikoreshereze ya module y'urumuri, silicon photonics izafatanya n'ikoranabuhanga ryo guhuza imiterere y'amafoto ya III-V, bitewe nuko ikoranabuhanga rya silicon photonics rifite uburyo bwo guhuza imiterere y'amafoto, umuvuduko mwinshi, kandi rijyanye neza n'imikorere ya CMOS iriho. Silicon photonics yagiye ikoreshwa buhoro buhoro mu mikoreshereze y'amafoto y'urumuri ikoreshwa mu ntera nto n'iciriritse, kandi yabaye igisubizo cya mbere cyo gushakisha CPO. Inganda zifite icyizere cy'iterambere ry'ikoranabuhanga rya silicon photonics mu gihe kizaza, kandi ubushakashatsi bwaryo mu mikoreshereze y'amafoto y'urumuri n'izindi nzego nabyo bizahuzwa.
