Kodi pali kusiyana pakati pa FTTB ndi FTTH?

1. Zipangizo zosiyanasiyana

Pamene FTTB yayikidwa, zipangizo za ONU zimafunika; Zida za ONU za FTTH zimayikidwa m'bokosi m'dera linalake la nyumbayo, ndipo makina oyikidwa a wogwiritsa ntchito amalumikizidwa ku chipinda cha wogwiritsa ntchito kudzera mu zingwe za Gulu 5.

2. Mphamvu zosiyana zoyikidwa

FTTB ndi chingwe cha fiber optic chomwe chimalowa m'nyumba, ogwiritsa ntchito amatha kugwiritsa ntchito fiber pogwiritsa ntchito foni, broadband, IPTV ndi ntchito zina; FTTH ndi chingwe cha fiber optic chomwe chimapita ku khonde kapena ku nyumbayo.

3. Ma liwiro osiyanasiyana a netiweki

FTTH ili ndi liwiro la intaneti lalikulu kuposa FTTB.

Ubwino ndi kuipa kwa FTTB:

ubwino:

FTTB imagwiritsa ntchito njira yolumikizirana ndi intaneti yapadera, palibe dial-up (China Telecom Feiyoung imadziwika kuti fiber-to-the-home, zomwe zimafuna kasitomala, ndipo dial-up imafunika). Ndi yosavuta kuyiyika. Kasitomala amangofunika kuyika khadi la netiweki pakompyuta kuti azitha kugwiritsa ntchito intaneti mwachangu maola 24. FTTB imapereka chiwongola dzanja chapamwamba kwambiri cha uplink ndi downlink cha 10Mbps (chokha). Ndipo kutengera malire a liwiro la IP ndi broadband yonse, kuchedwa sikudzawonjezeka.

kusowa:

Ubwino wa FTTB ngati njira yopezera intaneti yothamanga kwambiri ndi wodziwikiratu, koma tiyeneranso kuwona zofooka zake. Ma ISP ayenera kuyika ndalama zambiri poyika ma netiweki othamanga kwambiri m'nyumba ya wogwiritsa ntchito aliyense, zomwe zimalepheretsa kwambiri kukwezedwa ndi kugwiritsidwa ntchito kwa FTTB. Anthu ambiri ogwiritsa ntchito intaneti amatha kulipira ndipo amafunikabe kugwira ntchito yambiri.
