Kugeza ubu, kubijyanye na optique ya fibre optique ya tekinoroji, imiyoboro migari igenda isimburwa buhoro buhoro no kubona umurongo mugari, kandi amaherezo fibre home iragerwaho. Umuyoboro mugari wa optique ya fibre ya enterineti ihinduka byanze bikunze, kandi tekinoroji ya PON izahinduka ihuriro rya tekiniki ryumuyoboro mugari mugihe kizaza kubera serivisi nyinshi, ishoramari rito no kubungabunga byoroshye.
Umuyoboro wa fibre ni iki?
Umuyoboro wa optique wa fibre optique bivuga umuyoboro winjira aho uburyo bwo kohereza ari fibre optique. Imiyoboro ya fibre optique irashobora kugabanywa muburyo bubiri muburyo bwa tekinike: imiyoboro ikora neza (AON, Active Optical Network) hamwe na optique ya optique (PON, Passive Optical Network).
Umuyoboro wa optique urashobora kugabanywamo AON ishingiye kuri SDH na AON ishingiye kuri PDH;
Imiyoboro ya optique irashobora kugabanywamo umurongo mugari PON na Broadband PON.
Ni uruhe ruhare umuyoboro winjira ugira mu kubaka urusobe?
Umuyoboro wamakuru ugizwe numuyoboro wibanze wumugongo, umuyoboro wumujyi wa metropolitani, umuyoboro winjira, numuyoboro wabakiriya. Umuyoboro winjira uri ku kiraro cyumujyi wa metropolitani / umuyoboro wumugongo.
Kugeza ubu, siyanse n'ikoranabuhanga biratera imbere cyane, kandi umubare munini w'amadosiye ya elegitoronike uhora ukora. Hamwe n’ubukungu bw’isi yose hamwe n’umuvuduko wihuse wo kumenyekanisha amakuru, interineti yaramamaye cyane, serivisi z’amakuru ziyongera cyane, kandi ubwoko bwa serivisi z’itumanaho bwakomeje kwiyongera. Ubwoko bwubucuruzi. Umuyoboro mugari wa enterineti wahindutse icyuho kibuza iterambere ryumuyoboro mugari. Isoko ry'urusobe rwinjira rufite ubushobozi bunini, kandi tekinolojiya mishya ihora igaragara kugirango ihuze ibyo abakoresha bakeneye. Umuyoboro winjira nicyo wibandwaho nurufunguzo rwiterambere ryibikorwa remezo byigihugu. Ikorana buhanga rya tekinoroji ryahindutse intandaro n’ishoramari ry’ibigo by’ubushakashatsi, abacuruza itumanaho, amasosiyete y’itumanaho n’amashami akora.
Ibyiza bya PON
1. Irashobora gutanga umurongo mugari mugari hamwe nubushobozi buke bwo kohereza.
2. Ugereranije numuyoboro wa optique ukora, kwishyiriraho, gutangiza no kubungabunga ibikorwa byo hasi ni bike, kandi sisitemu irizewe kandi ihamye, bityo umuyoboro winjira urimo gukoresha umubare munini wa sisitemu ya PON.
3. Kuberako PON ikoresha uburyo-bwo-kugana uburyo bwo kugera, ikiguzi cyibikorwa remezo cyo gushyira fibre optique hagati yibiro bikuru n’abakoresha bishyurwa n’abakoresha, bishobora kongera inyungu ku ishoramari mu iyubakwa ry’urusobe. Ugereranije nuburyo bwo gushiraho fibre optique iherezo-iherezo kuri buri mukoresha, ingano yibikoresho bya PON itezimbere serivisi kumubare umwe wabakiriya ni nto kandi ifata umwanya muto mubiro bikuru.

5.PON ishyigikira abakoresha bose batuye (ukoresheje POTS, TV igereranya na serivisi zamakuru) hamwe nabakoresha benshi mubucuruzi (ukoresheje serivisi ya T1 / E1 na Ethernet) kugirango basangire umuyoboro winjira (harimo urwego rwumubiri na protocole layer) utiriwe ukoresha uburyo butandukanye Kugera kumurongo bitanga serivisi kuri bo, bityo bikagabanya umubare wimiyoboro itatanye.
