Yiziphi izinhlobo ezintathu zezintambo ze-fiber optic?

I-fibre yemodi eyodwa uhlobo lwe-fibre oludlulisela imodi eyodwa kuphela (indlela) yokukhanya. Ine-core encane kakhulu (ngokuvamile ububanzi obuyi-8-10 microns).

Indlela esebenza ngayo: Ngenxa yokuthi umongo mncane kakhulu, ukukhanya kusakazeka endleleni eyodwa eqondile, ngaphandle kokukhanya noma ukuhlakazeka. Kufana nomsebe we-laser pointer—kugxile kakhulu.

Izici:

• I-bandwidth ephezulu kakhulu kanye nebanga elide kakhulu lokudlulisela: Ngenxa yokuthi akukho ukuhlakazeka kwe-modal (ukuphazamiseka kwesignali okubangelwa izikhathi ezahlukene zokufika kokukhanya ngezindlela ezahlukene), izimpawu zingadluliselwa emabangeni amade ngokuncipha okuncane.
• Izindleko eziphezulu: Kudinga i-laser njengomthombo wokukhanya, futhi inqubo yokuhlanganisa (i-fusion splicing) inzima kakhulu.

Izinhlelo zokusebenza eziyinhloko:

• Ukuxhumana okude (amanethiwekhi endawo yedolobha, amanethiwekhi kazwelonke aqinile)
• Izintambo zamanzi angaphansi kolwandle ezidlula olwandle
• Izinhlelo zethelevishini yekhebula (CATV)
• Ukuxhumana kwesikhungo sedatha esinesivinini esikhulu

I-fibre ye-Multimode inomgogodla ojiyile (ngokuvamile ama-micron angu-50 noma angu-62.5), okuvumela ukukhanya ukuthi kudluliselwe ngesikhathi esisodwa ngezindlela eziningi (izindlela).

Isimiso Sokusebenza: Ukukhanya kuhamba ngama-engeli ahlukahlukene ngaphakathi kobukhulu obukhulu I-Fiber CoreIzindlela ezahlukene zokukhanya zinezindlela ezihlukene zobude futhi zifika lapho ziya khona ngezikhathi ezihlukile kancane.

Izici:

• Ibanga elifushane lokudlulisela: Ngenxa "yokusabalala kwe-modal," ama-pulse esignali ayanda kancane kancane futhi aphendukezeleke ngokuhamba kwebanga, okunciphisa ibanga lokudlulisela.
• Umkhawulokudonsa ophansi: Uma kuqhathaniswa ne-fiber yemodi eyodwa, le fiber ine-bandwidth ephansi.
• Izindleko eziphansi: Ngokuvamile isebenzisa ama-LED noma ama-laser e-VCSEL ashibhile njengomthombo wokukhanya, futhi izidingo zokuxhumanisa kanye nezixhumi aziqinile njengalezo zefayibha yemodi eyodwa.

Izinhlelo zokusebenza eziyinhloko:

• Amanethiwekhi endawo (ama-LAN) ngaphakathi kwezakhiwo
• Ukuxhumeka kweseva yesikhungo sedatha
• Izinhlelo zokuqapha
• Ukuxhumana okude (ngokuvamile ngaphakathi kwamakhilomitha ambalwa)

Amabanga avamile e-fiber ye-multimode:

• OM1: Yendabuko engu-62.5/125μm, ngokuvamile enejakethi e-orange.
• OM2: Okujwayelekile okungu-50/125μm, nejakethi ephuzi.
• I-OM3/OM4: I-fiber ye-multimode engu-50/125μm eyenziwe ngcono nge-laser ye-10G, 40G, kanye ne-100G Ethernet, enejakethi eluhlaza okwesibhakabhaka enamanzi.
• I-OM5: I-fiber ye-Broadband multimode, esekela ubude obufushane bamaza, enejakethi eluhlaza okwesibhakabhaka.

Kokubili ingaphakathi kanye nokumbozwa kwefayibha yepulasitiki kwenziwa ngepulasitiki (njenge-PMMA).

Isimiso Sokusebenza: Kufana nefayibha yengilazi, kodwa kusetshenziswa ipulasitiki njengendlela yokudlulisa.

Izici:

• Izindleko Eziphansi Kakhulu: Izindleko zezinto zokwakha kanye nezokukhiqiza ziphansi kakhulu.
• Kulula Ukuyifaka:I I-Fiber Core iwugqinsi (cishe u-1 mm) futhi iguquguquka kakhulu, okuvumela ukuthi isikwe futhi ixhunywe ngamathuluzi alula, okususa isidingo semishini ekhethekile yokuhlanganisa.
• Ukunciphisa okuphezulu, i-bandwidth ephansi, kanye nebanga lokudlulisela elifushane kakhulu: Ipulasitiki ilahlekelwa ukukhanya okukhulu kakhulu kunengilazi futhi ayimelani nokushisa.

Izicelo Eziyinhloko:

• Amanethiwekhi angaphakathi kwemoto (isb., izinhlelo zokuzijabulisa ezingaphakathi kwemoto)
• Ukuxhumana okufushane phakathi kwamadivayisi omsindo/ividiyo asekhaya
• Izinhlelo zokulawula zezimboni (izindawo ezifushane, ezine-EMI ephezulu)
• Ukukhanyisa okuhlobisa
