Hangaia te punaha Fiber Optic Cellular Repeater (FOR) ki te whakaoti rapanga o te tohu waea pūkoro ngoikore i te waahi kei tawhiti atu i te BTS (Base Transceiver Station) me te whatunga taura muka whatu kei raro.
Whakaotihia nga waahi uaua ki te toro atu!
E rua nga wahanga o te punaha FOR katoa: Wae Kaituku me te Wae Mamao.He maamaa te kawe me te whakanui i te tohu ahokore i waenga i te BTS (Base Transceiver Station) me nga waea pūkoro ma nga taura muka.
Ka hopuhia e te waeine Donor te tohu BTS ma te hononga hono katia ki te BTS (ma te tuku RF rangi tuwhera ranei ma te Donor Antenna), ka huri hei tohu optic me te tuku i te tohu whakakaha ki te Waehe Mamao ma nga taura muka.Ka huri ano te Waeine Mamao i te tohu mata ki te tohu RF me te tuku i te tohu ki nga waahi kaore i te tika te kapinga whatunga.Na ka whakanuia ano te tohu pūkoro ka tukuna ano ki te BTS ma te huarahi rereke.
KingtoneTe Repeater Fiber OpticKua hoahoatia te punaha ki te whakaoti rapanga o te tohu pūkoro ngoikore, he iti ake te utu i te tatūnga i te Teihana Turanga hou (BTS).Te mahinga matua o te punaha Repeater RF: Mo te hononga ki raro, ka tukuna nga tohu mai i te BTS ki te Waenga Kaiwhiwhi (DOU), ka huri te DOU i te tohu RF ki te tohu laser ka whangai ki te muka hei tuku ki te Waehe Mamao (ROU).Ka huri a RU i te tohu taiaho ki te tohu RF, ka whakamahi i te Power Amplifier ki te whakanui i te mana teitei ki te IBS, ki te antenna kapinga ranei.Mo te hono ki runga, He tukanga whakamuri, ka tukuna nga tohu mai i te waea pūkoro ki te tauranga MS o DOU.Ma te duplexer, ka whakanuia te tohu e te iti o te haruru whakakaha hei whakapai ake i te kaha tohu.Na ka tukuna nga tohu ki te RF muka whatu kōwae ka huri ki nga tohu laser, ka tukuna te tohu laser ki DOU, ka huri te tohu laser mai i te ROU ki te tohu RF na te RF optical transceiver.Na ka whakanuia nga tohu RF ki nga tohu kaha ka whangaia ki te BTS.
Ngā āhuatanga
- He nui te atete ki te puehu, te wai me te waikura o te pouaka konumohe;
- Ka taea te tango i te antenna kapinga omni-directional ki te whakawhānui ake i te kapinga;
- Te tango i te waahanga WDM (Wavelength Division Multiplexing) ki te mohio ki te tuku tawhiti;
- He pumau me te whakapai ake i te kounga tuku tohu;
- Ka taea e tetahi Waeine Kaituku te tautoko ake ki te 4 Waehe Mamao hei whakanui ake i te whakamahinga o te taura muka;
- Ko nga tauranga RS-232 he hononga ki tetahi pukatuhi mo te tirotiro a rohe me te pouwhanga ahokore i hangaia ki te korero ki te NMS (Punaha Whakahaere Whatunga) ka taea te tirotiro mamao i te mana mahi o te kaitoi me te tango i nga tawhā mahi ki te kaitoi.
