Kodi FTTH ndi chiyani?

Tikamalankhula za FTTHChoyamba, tifunika kukambirana za mwayi wopeza fiber optic. Kupeza fiber optic kumatanthauza kuti fiber optic imagwiritsidwa ntchito ngati njira yotumizira mauthenga pakati pa ofesi yapakati ndi wogwiritsa ntchito. Kupeza fiber optic kungagawidwe m'magulu awiri: active optic access ndi passive optical access. Ukadaulo waukulu wa netiweki ya fiber optic subscriber ndi ukadaulo wotumizira mauthenga a kuwala. Ukadaulo wochulukitsa mauthenga a fiber optic ukukula mofulumira kwambiri, ndipo zambiri zake zikugwiritsidwa ntchito kale. Kutengera ndi kuchuluka kwa momwe fiber imalowera pakati pa ogwiritsa ntchito, imatha kugawidwa m'magulu awiri: FTTC, FTTZ, FTTO, FTTF, FTTH, ndi zina zotero.

Fiber To The Home (FTTH, yomwe imadziwikanso kuti Fiber To The Premises) ndi njira yotumizira mauthenga kudzera pa chingwe cha fiber optic. Imalumikiza chingwe cha fiber optic mwachindunji kunyumba kwa wogwiritsa ntchito (kulikonse komwe wogwiritsa ntchito akuchifuna). Makamaka, FTTH imatanthauza kuyika kwa Optical Network Units (ONUs) m'nyumba kapena m'malo amalonda, ndipo ndi mtundu wa pulogalamu ya optical access network yomwe ili pafupi kwambiri ndi wogwiritsa ntchito mu optical access series, kupatula FTTD (Fiber To The Desktop). Chinthu chachikulu chaukadaulo cha FTTH ndichakuti sichimangopereka bandwidth yayikulu komanso chimawongolera kuwonekera bwino kwa netiweki pankhani ya mawonekedwe a data, liwiro, ma wavelength, ndi ma protocol, chimamasula zofunikira zachilengedwe ndi zamagetsi, komanso chimathandizira kukonza ndi kukhazikitsa mosavuta.
