Isahluko 1 Iimpawu ezineenkcukacha ze-Optical ze-Six Classic Fiber Communication Wavebands

1.1 850 nm (Ifestile yobude obufutshane, Ifestile yoNxibelelwano lokuQala lwe-Optical)

I-850 nm yeyona wavelength yonxibelelwano yokuqala ethengiswayo esetyenziselwa i-multimode optical fiber. Umthombo wayo wokulahleka ophambili uvela kwi-Rayleigh scattering, apho ukuncitshiswa kwayo kufana kakhulu namandla esine e-wavelength. Ngenxa ye-optical wavelength emfutshane, ukuncitshiswa kwe-fiber eqhelekileyo kususela kwi-2.5 ukuya kwi-3.0 dB/km, inqanaba eliphezulu lokulahleka phakathi kwama-waveband amathandathu. Akukho ndawo yokusasazeka kwe-zero ekhoyo kwi-850 nm; ukusasazeka kwezinto ezidibeneyo kunye nokusasazeka kwe-intermodal kwandisa kakhulu ii-optical pulses kwaye kuthintele ukufikelela kokudluliselwa. Kwi-OM1 kunye ne-OM2 multimode fiber, ukufikelela okuphezulu kwe-Gigabit Ethernet yi-550 m kunye ne-220 m ngokulandelelana kwi-850 nm, ngelixa i-10G Ethernet ixhasa kuphela i-33 m (OM1) kunye ne-82 m (OM2).

IiLaser ezikhupha umphezulu ezikwi-Vertical-Cavity Surface-Emitting (VCSELs) ziyimithombo yokukhanya eqhelekileyo yale band ene-compact packaging, ixabiso eliphantsi kwaye akukho mfuneko yokupholisa eyongezelelweyo.

Kwiinethiwekhi zonxibelelwano ezikhawulezayo zanamhlanje, intambo yefayibha iye yaba yenye yezona zinto zibalulekileyo zokudibanisa izixhobo ze-optical, izixhobo zenethiwekhi, kunye neenkqubo zokusasazwa kwefayibha. Ukusuka kumaziko edatha kunye neenethiwekhi zonxibelelwano ukuya kwi-FTTH (Fiber to the Home) deployments kunye neenkqubo zonxibelelwano lweshishini, iintambo ze-fiber patch zibonelela ngoqhagamshelo lwe-optical oluthembekileyo nolusebenza kakuhle.

Uhlalutyo olupheleleyo lwe-G.657.A1, G.657.A2 kunye ne-G.657.B3

Ngokusetyenziswa okukhulu kwe-FTTH Fiber eKhaya, amaziko edatha e-AI computing, i-5G fronthaul, i-indoor comprehensive wiring, i-FPV drone miniature communication kunye nokwakhiwa kohlaziyo lwangoku olubuthathaka kwihlabathi liphela, i-G.652D single-mode fiber yendabuko ihlushwa kukulahleka okukhulu kokugoba kunye nendawo encinci yocingo, nto leyo ethintela kakhulu ulwakhiwo lweenethiwekhi zonxibelelwano ze-optical ezikhawulezayo. Yenziwe yi-ITU-T, i-G.657 series bend-insensitive single-mode fiber yenzelwe ngokukodwa iikona ezijijekileyo, i-dense wiring kunye ne-micro-pipeline. Amanqanaba amathathu emveliso ephambili, i-G.657.A1 standard bend-resistant fiber, i-G.657.A2 ephuculweyo bend-resistant fiber kunye ne-G.657.B3 ultra-bend-insensitive fiber, isebenzisa iiprofayili ze-refractive index ezincediswa yi-trench-assisted refractive index, kwaye ibonisa umahluko olinganisiweyo kwi-minimum bending radius, i-mode field diameter kunye nokusebenza kwe-attenuation. Zigubungela iimfuno zemeko epheleleyo ukusuka kwi-wiring yasekhaya engabizi kakhulu ukuya kwi-ultra-compact special wiring.
