Kodi FTTx ndi chiyani?
FTTx ndi "Fiber To The x" ndipo ndi nthawi yodziwika bwino yofikira ulusi mu fiber optic communications. x imayimira kopita kwa mzere wa ulusi. Monga x = H (Fiber to Home), x = O (Fiber to the Office), x = B (Fiber to Building). Ukadaulo wa FTTx umachokera ku zida zapakati zamaofesi muchipinda cholumikizirana chamchigawo kupita ku zida zogwiritsira ntchito, kuphatikiza optical line terminal (OLT), mawonekedwe a netiweki (ONU), optical network terminal (ONT).
Malinga ndi malo aONUPamapeto a optical network unit, pali mitundu yambiri ya FTTx, yomwe imatha kugawidwa kukhala fiberkusinthabokosi (FTTCab), CHIKWANGWANI m'mphepete mwa msewu (FTTC), CHIKWANGWANI kupita kunyumba (FTTB), CHIKWANGWANI kunyumba (FTTH), CHIKWANGWANI Ku ofesi (FTTO) ndi mafomu ena utumiki. Wogwiritsa ntchito ku US Verizon amatanthauza FTTB ndi FTTH ngati fiber to the premises (FTTP).
Chithunzi cha FTCab(Fiber ku Cabinet）
Chingwe chachikhalidwe chimasinthidwa ndi kuwala kwa fiber. TheONUimayikidwa pa bokosi lolumikizirana. TheONUpansipa amagwiritsa ntchito waya wamkuwa kapena zoulutsira zina kuti alumikizane ndi wogwiritsa ntchito.
Mtengo wa FTTC(Fiber Kwa Curb）
Kuyika ndi kugwiritsa ntchito zingwe za kuwala kuchokera ku ofesi yapakati kupita m'mphepete mwa misewu mkati mwa nyumba kapena maofesi. Nthawi zambiri, ulalo womwe ungakhalepo wa burodibandi womwe uli pafupi kwambiri ndi wogwiritsa ntchito umayikidwa poyamba. Pakafunika ntchito za burodibandi, ulusiwo utha kutsogozedwa mwachangu kwa wogwiritsa ntchito ndipo ulusiwo ukhoza kufikika kunyumba.
Mtengo wa FTTB(Fiber Kunyumba)
Ndi njira yolumikizira ma Broadband kutengera ukadaulo wokometsedwa wa fiber network. Imagwiritsa ntchito fiber ku nyumbayo ndi chingwe cha netiweki kunyumba kuti ikwaniritse mwayi wogwiritsa ntchito burodibandi. Nthawi zambiri, mwayi wodzipatulira wodzipereka umagwiritsidwa ntchito, womwe ndi wosavuta kukhazikitsa ndipo ukhoza kupereka kumtunda ndi kumtunda kwa 10Mbps (kupatula).
FTTH(Fiber Kunyumba）
TTH imatanthawuza kukhazikitsa kwa optical network unit (ONU) kwa wogwiritsa ntchito kunyumba kapena wogwiritsa ntchito bizinesi. Ndi mtundu wa mawonekedwe ogwiritsira ntchito intaneti omwe ali pafupi kwambiri ndi wogwiritsa ntchito kupatula FTTD (optical fiber to desktop) pamndandanda wofikira. Ukadaulo wa PON wasanduka malo odziwika kwambiri omwe amagwiritsiridwa ntchito ndi ma burodibandi padziko lonse lapansi ndipo akuwoneka kuti ndi njira yabwino kwambiri yothetsera FTTH.
FTTP(Fiber Kumalo）
FTTP ndi mawu aku North America. Zimaphatikizapo FTTB, FTTC, ndi FTTH m'lingaliro lopapatiza, ndipo amafikira zingwe za kuwala kwa nyumba kapena mabizinesi.
