Amacakubiri ya optique ni kimwe mubikoresho byingenzi bya pasiporo muburyo bwa fibre optique, kandi ahanini bigira uruhare rwo gutandukana.Mubisanzwe bikoreshwa mumurongo wa optique ya OLT hamwe numuyoboro wa optique wa ONU ya pasiporo optique kugirango umenye ibimenyetso bya optique bigabanijwe.
Amacakubiri ya optique akwirakwiza ibimenyetso bya optique yoherejwe muri fibre optique kuri fibre optique.Hariho ubwoko bwinshi bwo gukwirakwiza, 1 × 2, 1 × 4, 1 × N, cyangwa 2 × 4, M × N. Imyubakire rusange ya FTTH ni: OLT (icyumba cyibiro bya mudasobwa iherezo) -ODN (sisitemu yo gukwirakwiza imiyoboro ya optique ) -ONU.Mu miterere ya PON, mugihe isaranganya ryinyubako ryatatanye kandi ridasanzwe, nko gukwirakwiza villa, intera iri kure, kandi ubucucike bwabakoresha buri hasi, uburyo bwo kugabana hagati burashobora gukoresha neza umutungo kandi bigatwikira ibidukikije.
Igice kimwe gusa gishobora gukoreshwa murusobe rwiza rwa optique, cyangwa ibice byinshi bya optique bishobora gukoreshwa hamwe kugirango bigabanye ibimenyetso bya optique.
Ibipimo byerekana imikorere bigira ingaruka nziza muri rusange ni ibi bikurikira:
Igihombo
Gutakaza igihombo cya fibre itandukanya bivuga umubare wa dB ya buri gisohoka ugereranije ninjiza optique.Mubisanzwe nukuvuga, ntoya kwinjiza agaciro.
Ikigereranyo cyo gutandukanya
Igabana ryagabanijwe risobanurwa nkibisohoka imbaraga za buri cyambu gisohoka cya fibre itandukanya.Mubisanzwe, igabanywa ryigabanywa rya PLC optique itandukanijwe iragabanijwe neza, kandi igabanywa ryikomatanyirizo rya optique itandukanijwe irashobora kutangana.
Igipimo cyihariye cyo kugereranya igabana rifitanye isano nuburebure bwumucyo woherejwe.Kurugero, iyo ishami rya optique ryohereza urumuri rwa micron 1.31, igabanywa ryibice byombi bisohoka ni 50:50;iyohereza 1.5μm urumuri, ruba 70: 30 (Impamvu ituma ibi bibaho nuko fibre itandukanya fibre ifite umurongo mugari, ni ukuvuga, umurongo wa signal ya optique yoherejwe mugihe igipimo cyo gutandukana kidahindutse).
Kwigunga
Kwigunga bivuga ubushobozi bwo kwigunga inzira imwe ya optique ya fibre optique itandukanya ibimenyetso bya optique mubindi bice bya optique.
Garuka igihombo
Gutakaza igihombo, nanone byitwa gutakaza ibitekerezo, bivuga gutakaza ingufu za signal optique yagarutse cyangwa bigaragazwa no guhagarika umurongo wa fibre cyangwa umurongo wohereza.
Ninshi gutakaza igihombo, nibyiza, kugabanya ingaruka zumucyo ugaragara kumasoko yumucyo na sisitemu.
Mubyongeyeho, uburinganire, kuyobora, gutakaza PDL polarisiyasi, nibindi nabyo ni ibipimo bigira ingaruka kumikorere ya optique itandukanya.Optical fibre splitter nimwe mubikoresho byingenzi bya pasiporo ihuza optique ya fibre optique, kandi irakwiriye cyane cyane guhuza MDF nibikoresho bya terefone mumashanyarazi ya optique (EPON, GPON, BPON, FTTX, FTTH, nibindi) gukwirakwiza ibimenyetso bya optique.
