TETRA Fiber Optical repeaters imakhala ndi Master Unit (MU) ndi Remote Unit (RU).Master Unit imodzi imatha kugwira ntchito limodzi ndi 1 mpaka 4 Magawo Akutali.Master Unit imasamutsa siginecha ya BTS kukhala siginecha ya kuwala ndikutumiza chizindikiro ku Remote Unit (RU).Remote Unit (RU) imasamutsa siginecha ya kuwala mu siginecha ya RF, kukulitsa chizindikiro cha RF ndikuphimba madera omwe mukufuna.
Optical remote unit (RU) imalumikizidwa ndi master unit kudzera pa fiber optical.Zizindikiro za BTS zimalumikizidwa ku master unit yosinthira magetsi / kuwala.Zizindikiro zosinthidwazi zimatumizidwa kudzera mu fiber optical kupita ku mayunitsi akutali ndipo pamapeto pake mpaka mlongoti.Pogwiritsa ntchito zingwe zama fiber, kutayika kwakukulu kwa zingwe zazitali za coaxial kumapewa.
Izi zimawonjezera mtunda womwe ungakhalepo pakati pa unit unit ndi master unit mpaka 20 km.Subcarrier imadyetsedwa munjira yolumikizira pa optical fiber kuti ikhale ngati njira yowongolera komanso kuyang'anira zida zonse.Chifukwa cha lingaliro modular pambuyo kukulitsa ndi kukweza n'zotheka.Kusintha kwadongosolo kungathenso kuperekedwa pamtengo wotsika mtengo.
• Zotsika mtengo za m'nyumba cell zowonjezera
• Kuyika kosavuta chifukwa cha miyeso yaying'ono ndi ntchito zopindula zokha
• Kudalirika kwakukulu
Zobwereza zodyetsedwa ndi fiber zamawayilesi anjira ziwiri.Optical fiber yankho la kuphimba m'nyumba ndi kufalikira kwamitundu mu VHF, UHF ndi TETRA ma frequency.
Mapangidwe awa adagawa makina a antenna (DAS) opangira mawayilesi opanda zingwe.
Mapulogalamu Odziwika:
TETRA Fiber Optical Repeaters amagwiritsidwa ntchito makamaka m'malo amkati ndi kunja komwe kuli kale ndi ulusi wamaso.Kugwiritsa ntchito kwa Tetra Fiber Optical repeaters kudzathetsa bwino malo akhungu, kupititsa patsogolo khalidwe la intaneti, kupititsa patsogolo chithunzi cha ogwiritsira ntchito ma cellular ndi kuwabweretsera phindu lochulukirapo.
