A5: G.657.A2 ndiye ulusi wofananira wofunikira kwambiri pa maoda otumizira kunja a broadband. Zingwe zotsika mtengo kwambiri za G.657.B3 zimapezeka pamapulojekiti apamwamba a mawaya oletsa moto m'nyumba ndi m'mabizinesi ku Europe ndi America.

Q6: Kodi G.657.A1, A2 ndi B3 zingasiyanitsidwe ndi mawonekedwe okha?

A6: Zophimba zopanda ulusi sizikuwonetsa kusiyana kooneka. Kuzindikiritsa kuyenera kudalira kutayika kwa macro-bending ndi deta yochepa yozungulira yozungulira kuchokera ku malipoti oyesera a fakitale ya opanga. Ogula ayenera kupempha mapepala ovomerezeka a ITU-T panthawi yogula kuti apewe kulephera kwaukadaulo komwe kumachitika chifukwa cha ogulitsa otsika mtengo kupereka G.657.A1 ngati A2 kapena A2 ngati B3 pamitengo yotsika.

8. Mapeto: Mfundo Yosankha Kwambiri & Kubweza Ndalama Kwanthawi Yaitali

G.657.A1, G.657.A2 ndi G.657.B3 amapanga mtundu wathunthu wa zinthu zomwe zimaphimba mawaya ambiri osawononga ndalama zambiri, mawaya olinganizidwa bwino komanso mawaya apadera kwambiri olimbana ndi kupindika kwambiri. Mfundo yosankha mawaya imadalira zizindikiro zinayi zazikulu za polojekitiyi: m'lifupi mwa malo olumikizirana mawaya, kuchuluka kwa kupindika kwa ulusi, zofunikira pakugwirizana kwa netiweki yakale komanso bajeti yonse ya polojekitiyi.

Mapulojekiti otsika mtengo okhala ndi mawaya akuluakulu komanso kukonzanso netiweki yakale: G.657.A1 imapereka phindu lalifupi kwambiri pa nthawi yonse yogulira.
90% ya ma network a anthu wamba, malo osungira deta, ndi mawaya a 5G: G.657.A2 ikuyimira mtengo wapamwamba kwambiri ndipo ikadali chisankho chachikulu cha msika wapadziko lonse lapansi.
Mapaipi obisika mopapatiza kwambiri, mawaya osinthasintha a mafakitale, ma drone ndi kulumikizana kolondola kwa zida zapadera: G.657.B3 imapereka kukana kopindika kodalirika kwambiri kuti isunge kutumiza kwa chizindikiro kwa nthawi yayitali ndikuchepetsa ndalama zokonzera pambuyo pogulitsa mapulojekiti apamwamba.

Chifukwa cha kufalikira kosalekeza kwa zomangamanga za digito padziko lonse lapansi, maukonde a AI computing ndi Gigabit fiber broadband, fiber ya G.657 yosagwedezeka idzalowa m'malo mwa fiber yachikhalidwe ya G.652D kuti igwiritsidwe ntchito pa mawaya ofikira mwachangu. Opanga mawaya a kuwala, ogula malonda akunja, ndi makontrakitala opanga mainjiniya ayenera kufananiza bwino magiredi a fiber ya G.657.A1/A2/B3 kutengera zochitika za polojekiti, kulinganiza ndalama zogulira pasadakhale komanso ndalama zogwirira ntchito zomanga ndi zotayika kwa nthawi yayitali kuti awonjezere kukhazikika kwa kulumikizana kwa kuwala komanso phindu lonse la polojekiti.

Kusiyana kwa G.657.A1 ndi G.657.A2 ndi G.657.B3, G657A1 single mode fiber specifications, G657A2 FTTH drop cable fiber, G657B3 ultra bend insensitive fiber, ITU-T G.657 standard fiber, bend insensitive fiber selection guide, fiber for AI data center high density wiring, 5G FTTA fiber cable core, FPV drone communication fiber, G.657 macro bending loss parameter, G657 fiber fusion splicing compatibility, fiber preform manufacturing process, indoor tight buffered fiber core type, optical cable export fiber grade select, single mode bending radius comparison
