CHIYAMBI CHACHIFUPI:
Ma node a SR102BF-F Optical amapangidwira ma netiweki a fiber-to-the-home (FTTH), okhala ndi mzere wabwino kwambiri komanso wosalala, kuonetsetsa kuti ma signali atumizidwa bwino, kuchepetsa kusokonekera, komanso kupereka chidziwitso chapamwamba cha mawu, makanema, ndi deta. Ndi mphamvu zambiri zolowera zamagetsi, imatha kusintha malinga ndi malo osiyanasiyana a netiweki ndi mikhalidwe ya ma signali, ndipo imatha kugwira ntchito bwino m'malo osiyanasiyana popanda kusintha magawo pafupipafupi, kuchepetsa zovuta zoyika ndi kukonza. Imagwiritsa ntchito ukadaulo wa single-mode optical fiber, womwe uli ndi mawonekedwe otayika kwambiri, omwe amatha kuchepetsa kusokonezedwa kwa kuwala komwe kumawonetsedwa ndikuwonetsetsa kuti ma signali ndi abwino komanso mtundu wa ma signali panthawi yotumiza mtunda wautali. Mkati, zida zogwira ntchito za GaAs amplifier zimagwiritsidwa ntchito kuti zikwaniritse bwino, phokoso lotsika komanso kusintha chiŵerengero cha ma signali-to-noise ndi kuyenda kwa ma elekitironi ambiri komanso magwiridwe antchito abwino a ma frequency apamwamba. Nthawi yomweyo, kugwiritsa ntchito ukadaulo wa phokoso wa subwoofer, kudzera mu kapangidwe kapamwamba ka dera ndi ma algorithms ochepetsa phokoso, kumachepetsa phokoso la chipangizocho kukhala lotsika kwambiri, kumatsimikizira kuyera kwa chizindikiro chotulutsa, komanso kumapereka kulumikizana kokhazikika kwa netiweki ngakhale m'malo ovuta amagetsi. Chogulitsachi ndi chaching'ono kukula kwake, chosavuta kuyika m'malo osiyanasiyana, choyendetsedwa ndi adaputala yamagetsi ya USB, chomwe chimapangitsa kuti chingwecho chikhale chosavuta komanso chothandiza kuti magetsi azisinthasintha, chokhala ndi kutalika kwa 1550nm komanso pafupipafupi ya 45 ~ 1000MHz, chimagwirizana ndi zida zambiri za netiweki ya fiber optical, zomwe zimakwaniritsa zosowa zosiyanasiyana zamabizinesi monga kutumiza ma TV a chingwe ndi mwayi wopeza deta mwachangu, ndipo ndi choyenera kumanga ndi kukweza netiweki ya FTTH.
