Amakuru

1. Sobanura ibice bya fibre optique.

Igisubizo: Fibre optique igizwe nibice bibiri byibanze: intangiriro nambaraga bikozwe mubikoresho bya optique bibonerana hamwe nigitambaro.

2. Nibihe bipimo fatizo bisobanura ibiranga ihererekanyabubasha rya fibre optique?

Igisubizo: harimo gutakaza, gutatanya, kwaguka, uburebure bwumurongo, uburebure bwa diameter, nibindi.

3. Ni izihe mpamvu zitera fibre optique?

Igisubizo: Optical fibre attenuation bivuga kugabanuka kwingufu za optique hagati yibice bibiri byambukiranya fibre optique, bifitanye isano nuburebure bwumuraba.Impamvu nyamukuru zitera kwiyitirira ni ugutatana, kwinjiza no gutakaza optique bitewe nabahuza.

4. Nigute coefficient ya attenuation ya fibre optique isobanurwa?

Igisubizo: Byasobanuwe na attenuation kuri buri burebure bwa fibre imwe muburyo butajegajega (dB / km).

5. Igihombo cyo gushiramo ni iki?

Igisubizo: Attenuation yatewe no kwinjiza ibintu bya optique (nkumuhuza cyangwa uhuza) mumurongo wohereza.

6. Umuyoboro mugari wa fibre optique ufitanye isano niki?

Igisubizo: umurongo wa fibre optique bivuga inshuro ya modulisiyo aho amplitude yingufu za optique igabanukaho 50% cyangwa 3dB uhereye kuri amplitude yumurongo wa zeru mumikorere yo kohereza fibre optique.Umuyoboro mugari wa fibre optique ugereranije nuburebure bwawo, kandi nibicuruzwa byuburebure buringaniye.

7. Ni ubuhe bwoko bwo gutatanya buri muri fibre optique?Niki?

Igisubizo: Gukwirakwiza fibre optique bivuga kwaguka gutinda kwitsinda muri fibre optique, harimo gukwirakwiza uburyo, gutatanya ibintu no gutatanya imiterere.Biterwa nibiranga isoko yumucyo na fibre optique.

8. Nigute dushobora gusobanura ibiranga ikwirakwizwa ryibimenyetso muri fibre optique?

Igisubizo: birashobora gusobanurwa nubwinshi butatu bwumubiri: kwaguka kwa pulse, optique ya fibre optique hamwe na coefficient de fibre optique.

9. Uburebure bwumurongo ni iki?

Igisubizo: Bivuga uburebure buke muri fibre optique ishobora kuyobora gusa uburyo bwibanze.Kuri fibre imwe-fibre, uburebure bwumurongo bugomba kuba bugufi kurenza uburebure bwumucyo woherejwe.

10. Ni izihe ngaruka gukwirakwiza fibre optique bigira ku mikorere ya sisitemu yo gutumanaho ya fibre optique?

Igisubizo: Ikwirakwizwa rya fibre bizagura impiswi ya optique mugihe igenda inyura muri fibre.Ihindura ingano yikosa rya biti, nuburebure bwintera yoherejwe, nubunini bwa sisitemu yihuta.

Kwaguka kwa optique ya optique muri fibre optique iterwa numuvuduko witsinda ryuburebure butandukanye bwumurambararo mubice bigize urumuri rwumucyo.

11. Gusubira inyuma ni iki?

Igisubizo: Gusubira inyuma nuburyo bwo gupima attenuation ku burebure bwa fibre optique.Byinshi mububasha bwa optique muri fibre ikwirakwiza imbere, ariko bike muri byo bisubira inyuma bigana kumurika.Igihe cyo kugarukira inyuma gishobora kugaragara ukoresheje optique itandukanya igikoresho cya luminescence.Ku mpera imwe, ntabwo hashobora gupimwa gusa uburebure no kwiyegereza fibre imwe ihuriweho irashobora gupimwa, ariko kandi harashobora gupimwa ibitagenda neza byaho, guhagarara no gutakaza ingufu za optique zatewe numuhuza hamwe nu muhuza.

12. Ni irihe hame ryikizamini cya optique igihe cyagenwe cyerekana (OTDR)?Ni uwuhe murimo ufite?

Igisubizo: OTDR ishingiye kumucyo winyuma hamwe nihame rya Fresnel ryerekana, mugihe ikoreshwa ryogukwirakwiza urumuri muri optique ya fibre optique yumucyo winyuma kugirango ubone amakuru, irashobora gukoreshwa mugupima optique ya optique, gutakaza igihombo, fibre optique ikosora kandi ikumva imiterere yo gutakaza igihombo muburebure bwa fibre optique, nibindi, nigice cyingenzi cyubwubatsi bwa fibre optique, kubungabunga no kugenzura ibikoresho.Ibipimo byingenzi byingenzi birimo urwego rufite imbaraga, ibyiyumvo, gukemura, igihe cyo gupima hamwe n'ahantu hatabona.
