Ingcaciso yeMveliso
Isishwankathelo esifutshane
I-SR812ST(R) sisixhobo sethu samva nje se-CATV network optical receiver esinazo iziphumo ezimbini. I-pre-amplifier isebenzisa i-full-GaAs MMIC, i-post-amplifier isebenzisa imodyuli ye-GaAs. Uyilo lwesekethe olulungisiweyo kunye namava ethu obuchwephesha kwiminyaka eli-10, yenza izixhobo zifikelele kwi-indexes yokusebenza okuhle. Ulawulo lwe-Microprocessor, ukuboniswa kwedijithali kweeparamitha, kunye nokulungiswa kweengxaki zobunjineli kulula kakhulu. Sisixhobo esiphambili sokwakha inethiwekhi ye-CATV.
Iimpawu zokusebenza
- Ityhubhu yokuguqula i-PIN ene-photoelectric ephendula kakhulu.
- Uyilo lwesekethe olulungiselelweyo, ukuveliswa kwenkqubo ye-SMT, kunye nendlela yesignali elungiselelweyo kwenza ukuhanjiswa kwesignali ye-photoelectric kube lula ngakumbi.
- Itshiphu yokuthomalalisa i-RF ekhethekileyo, enothomalaliso oluhle lwe-RF kunye nomgca olinganayo, ukuchaneka okuphezulu.
- Isixhobo se-amplifier se-GaAs, amandla aphuma kabini, kunye nokunyuka okuphezulu kunye nokuphazamiseka okuphantsi.
- Izixhobo zokulawula zeSingle Chip Microcomputer (SCM) ziyasebenza, i-LCD ibonisa iiparameter, ukusebenziseka lula kunye nokusebenza okubonakalayo, kunye nokusebenza okuzinzileyo.
- Ukusebenza kakuhle kwe-AGC, xa uluhlu lwamandla okufaka i-optical luyi-－9～＋2dBm, inqanaba lokukhupha lihlala lingatshintshanga, kwaye i-CTB kunye ne-CSO azitshintshanga.
- Unxibelelwano lwedatha olugciniweyo, lunokunxibelelana nempendulo yolawulo lwenethiwekhi yeklasi Ⅱ, kunye nokufikelela kwinkqubo yolawulo lwenethiwekhi.
- Ukukhupha umbane kwakhona kunokukhetha imo yokuqhuma ukunciphisa kakhulu ukudibana kwengxolo kunye nokunciphisa inani lomamkeli wangaphambili.
Iimeko zoVavanyo lweeKhonkco
Iiparameter zobugcisa zale ncwadi ngokwendlela yokulinganisa ye-GY/T 194-2003
1. Inxalenye yokufumana i-Forward optical: ene-10km standard optical fiber, i-passive optical attenuator, kunye ne-standard optical transmitter yenze ikhonkco lokuvavanya. Seta i-59 PAL-D analog TV channel signal kuluhlu lwe-45/87MHz～550MHz phantsi kokulahleka kwekhonkco elichaziweyo. Thumela i-digital modulation signal kuluhlu lwe-550MHz～862/1003MHz, inqanaba le-digital modulation signal (kwi-8 MHz bandwidth) liphantsi nge-10dB kunenqanaba le-analog signal carrier. Xa amandla okufaka i-optical e-optical receiver eyi--2dBm, inqanaba le-RF output yi-108dBμV, kunye ne-9dB output tilt, linganisa i-C/CTB, i-C/CSO, kunye ne-C/N.
2. Inxalenye yokudlulisa i-optical backward: I-Link flatness kunye ne-NPR dynamic range zii-link indexes ezenziwe yi-backward optical transmitter kunye ne-backward optical receiver.
Qaphela: Xa inqanaba lemveliso elilinganisiweyo liyi-configuration epheleleyo yenkqubo kwaye amandla okukhanya afumanayo yi-2dBm, isixhobo sihlangabezana nenqanaba eliphezulu lemveliso ye-link index. Xa uqwalaselo lwenkqubo luncipha (oko kukuthi, iitshaneli zothumelo zangempela ziyancipha), inqanaba lemveliso yesixhobo liya kwandiswa.
Isaziso Esinobuhlobo: Cebisa ukuba usete isignali ye-RF kwisiphumo sokuthambeka esingu-6~9dB kwisicelo sobunjineli esisebenzayo ukuphucula isalathisi esingelulo ulayini (phantsi kwe-node) yenkqubo yekhebula.
