Incazelo Yomkhiqizo
Ukubuka Okufushane
I-SR812ST(R) iyisamukeli sethu sakamuva senethiwekhi ye-CATV esinemiphumela emibili ephezulu. I-pre-amplifier isebenzisa i-full-GaAs MMIC, i-post-amplifier isebenzisa imojuli ye-GaAs. Umklamo wesekethe olungiselelwe kanye neminyaka yethu eyi-10 yesipiliyoni sokuklama kobungcweti, kwenza imishini ifinyelele ama-index amahle okusebenza. Ukulawulwa kwe-Microprocessor, ukuboniswa kwedijithali kwamapharamitha, ukulungisa amaphutha kobunjiniyela kulula kakhulu. Yimishini eyinhloko yokwakha inethiwekhi ye-CATV.
Izici Zokusebenza
- Ishubhu yokuguqula i-PIN ene-photoelectric ephendula kakhulu.
- Umklamo wesekethe olungiselelwe kahle, ukukhiqizwa kwenqubo ye-SMT, kanye nendlela yesignali eyenziwe kahle kwenza ukudluliswa kwesignali ye-photoelectric kube bushelelezi kakhudlwana.
- I-chip ekhethekile yokunciphisa i-RF, enokunciphisa okuhle kwe-RF kanye nokulingana okuqondile, ukunemba okuphezulu.
- Idivayisi ye-amplifier ye-GaAs, amandla aphuma kabili, ene-gain ephezulu kanye nokuphambuka okuphansi.
- Imishini yokulawula ye-Single Chip Microcomputer (SCM) iyasebenza, i-LCD ibonisa amapharamitha, ukusebenziseka kalula kanye nokusebenza okunembile, kanye nokusebenza okuzinzile.
- Ukusebenza okuhle kakhulu kwe-AGC, lapho ububanzi bamandla okufaka optical bungu-－9～＋2dBm, izinga lokukhipha lihlala lingashintshi, kanti i-CTB ne-CSO azishintshi.
- Isixhumanisi sokuxhumana kwedatha esigciniwe, singaxhumana nesiphenduli sokuphathwa kwenethiwekhi sekilasi Ⅱ, kanye nokufinyelela ohlelweni lokuphathwa kwenethiwekhi.
- Ukukhishwa komoya okubuyayo kungakhetha imodi yokuqhuma ukuze kwehliswe kakhulu ukuhlangana komsindo futhi kuncishiswe inombolo yomamukeli we-forepart.
Izimo Zokuhlola Isixhumanisi
Amapharamitha obuchwepheshe ale ncwadi ngokwendlela yokulinganisa ye-GY/T 194-2003
1. Ingxenye yokwamukela i-Forward optical: ene-fiber optical ejwayelekile engamakhilomitha ayi-10, i-attenuator ye-optical engasebenzisi i-passive, kanye ne-transmitter ejwayelekile ye-optical yakha isixhumanisi sokuhlola. Setha isignali yesiteshi se-analog TV engu-59 ye-PAL-D ebangeni elingu-45/87MHz～550MHz ngaphansi kokulahlekelwa kwesixhumanisi esichaziwe. Thumela isignali ye-modulation yedijithali ebangeni elingu-550MHz～862/1003MHz, izinga lesignali ye-modulation yedijithali (ku-bandwidth engu-8 MHz) liphansi ngo-10dB kunezinga lesithwali sesignali ye-analog. Lapho amandla okufaka optical we-optical receiver engu--2dBm, izinga lokukhipha le-RF lingu-108dBμV, ngokuthambekela kokukhipha okungu-9dB, kala i-C/CTB, i-C/CSO, kanye ne-C/N.
2. Ingxenye yokudlulisa i-optical backward: I-Link flatness kanye ne-NPR dynamic range yizinkomba ze-link ezakhiwe nge-backward optical transmitter kanye ne-backward optical receiver.
Qaphela: Uma izinga lokukhipha elilinganiselwe liwukulungiselelwa okugcwele kwesistimu futhi amandla okukhanya atholayo angu-2dBm, imishini ihlangabezana nezinga lokukhipha eliphezulu lenkomba yesixhumanisi. Uma ukulungiselelwa kwesistimu kuncipha (okungukuthi, iziteshi zokudlulisa zangempela ziyancipha), izinga lokukhipha lemishini lizokhushulwa.
Isaziso Esinobungane: Sikisela ukuthi usethe isignali ye-RF ku-6~9dB tilt output kuhlelo lokusebenza lobunjiniyela olusebenzayo ukuze uthuthukise inkomba engeyona eqondile (ngaphansi kwe-node) yesistimu yekhebula.
