Ingcaciso yeMveliso
Amagqabantshintshi amafutshane
I-SR812ST(R) sesona sixhobo sethu samva nje senqanaba eliphezulu lesibini le-CATV yenethiwekhi ye-optical receiver.I-pre-amplifier ithatha i-GaAs epheleleyo ye-MMIC, i-post-amplifier ithatha imodyuli ye-GaAs.Uyilo lwesekethe olulungiselelweyo oludityaniswe neminyaka eli-10 yamava oyilo lobuchwephesha, yenza ukuba izixhobo zifezekise izalathisi zokusebenza ezilungileyo.Ulawulo lweMicroprocessor, umboniso wedijithali weeparamitha, ukulungisa iimpazamo zobunjineli kulula ngakumbi.Sesona sixhobo siphambili sokwakha inethiwekhi yeCATV.
Iimpawu zoMsebenzi
-Impendulo ephezulu ye-PIN yokuguqula i-photoelectric tube.
-Uyilo lwesekethe olulungiselelwe, ukuveliswa kwenkqubo ye-SMT, kunye nendlela yesignali ephuculweyo yenza ukuhanjiswa kombane wefoto umbane ngakumbi.
-I-chip ekhethekileyo yeRF yokuthomalalisa, ene-RF attenuation elungileyo kunye ne-equilibrium linear, ukuchaneka okuphezulu.
-Isixhobo seamplifier ye-GaAs, amandla aphindwe kabini, kunye nenzuzo ephezulu kunye nokuphazamiseka okuphantsi.
-I-Single Chip Microcomputer (SCM) izixhobo zokulawula ezisebenzayo, i-LCD ibonisa iiparitha, ukulungeleka kunye nokusebenza kakuhle, kunye nokusebenza okuzinzile.
- Ukusebenza okugqwesileyo kwe-AGC, xa uluhlu lwamandla okufakwayo luyi-－9～＋2dBm, inqanaba lemveliso lihlala lingatshintshwanga, kunye ne-CTB kunye ne-CSO ngokwesiseko azitshintshanga.
-I-interface yonxibelelwano lwedatha egciniweyo, inokudibanisa neklasi Ⅱ umphenduli wolawulo lwenethiwekhi, kunye nokufikelela kwinkqubo yokulawula inethiwekhi.
-Ukukhutshwa kwembuyekezo kunokukhetha imo yokugqabhuka ukunciphisa ngokukhawuleza ukuhlangana kwengxolo kunye nokunciphisa inombolo yomamkeli wangaphambili.
Imiqathango yoVavanyo lwekhonkco
Iiparamitha zobugcisa zale ncwadana ngokwendlela yokulinganisa ye-GY/T 194-2003, kwaye ivavanywe kwezi meko zilandelayo.
1. Phambili i-optical ifumana inxalenye: kunye ne-10km i-fiber optical standard, i-passive optical attenuator, kunye ne-standard optical transmitter iqulunqe ikhonkco lokuvavanya.Seta i-59 PAL-D isignali yesitishi se-analog ye-TV kuluhlu lwe-45/87MHz ~ 550MHz phantsi kwelahleko yekhonkco echaziweyo.Dlulisa isiginali yokumodareyitha yedijithali kuluhlu lwe-550MHz ~862/1003MHz, inqanaba lesignali yokumodareyitha yedijithali (kwi-8 MHz bandwidth) yi-10dB ngaphantsi kwenqanaba lomthwali wesignali ye-analog.Xa igalelo lamandla optical optical receiver yi-2dBm, i-RF output level yi-108dBμV, kunye ne-9dB output tilt, umlinganiselo weC/CTB, C/CSO, kunye neC/N.
2. Inxalenye ye-Optical Transmit yasemva: Ikhonkco elithambileyo kunye noluhlu oluguquguqukayo lwe-NPR zizalathisi zekhonkco eziqulunqwe sisidluliseli sangasemva samehlo kunye nesamkeli sangemva samehlo.
Qaphela: Xa inqanaba lokuphuma elilinganisiweyo kukucwangciswa okupheleleyo kwenkqubo kunye nokufumana amandla optical -2dBm, isixhobo sidibana nenqanaba eliphezulu lokukhutshwa kwesalathisi sekhonkco.Xa ukucwangciswa kwenkqubo kunciphisa (oko kukuthi, iziteshi zothumelo zangempela zinciphisa), inqanaba lokukhutshwa kwezixhobo liya kwandiswa.
Isaziso sobuhlobo: Cebisa ukuba usete isignali ye-RF kwi-6 ~ 9dB i-tilt output kwisicelo sobunjineli obusebenzayo ukuphucula isalathisi esingenamgca (phantsi kwe-node) yenkqubo yentambo.
