Incamake
SR812ST (R) niyanyuma yanyuma-ibyiciro bibiri-bisohoka CATV neti optique yakira. Imbere-amplifier yemera-GaAs MMIC yuzuye, post-amplifier yemera module ya GaAs. Igishushanyo mbonera cyumuzingi gifatanije nuburambe bwimyaka 10 yubushakashatsi bwumwuga, kora ibikoresho bigere kubikorwa byiza. Igenzura rya Microprocessor, kwerekana imibare yibipimo, gukemura ibibazo byoroshye cyane. Nibikoresho nyamukuru byo kubaka umuyoboro wa CATV.
Ibiranga imikorere
- Igisubizo cyinshi PIN ifoto yamashanyarazi ihinduka.
.
- Chip yihariye ya attenuation chip, hamwe na RF nziza ya attenuation hamwe numurongo uringaniye, byukuri.
- Igikoresho cya GaAs cyongerera imbaraga, imbaraga zikubye kabiri, hamwe ninyungu nyinshi no kugoreka gake.
- Chip imwe ya Microcomputer (SCM) ibikoresho byo kugenzura bikora, LCD yerekana ibipimo, ibyoroshye nibikorwa byimbitse, hamwe nibikorwa bihamye.
- Imikorere myiza ya AGC, iyo ibyinjijwe optique yingufu zingana ni －9 ～＋ 2dBm, urwego rusohoka ntiruhinduka, na CTB na CSO muburyo budahinduka.
- Ububiko bwamakuru bwitumanaho bwabitswe, burashobora guhuza nicyiciro management imiyoboro yubuyobozi, no kugera kuri sisitemu yo gucunga imiyoboro.
- Garuka ibyuka birashobora guhitamo uburyo bwo guturika kugirango bigabanye cyane urusaku rw urusaku no kugabanya umubare wabakiriye mbere.
Ihuza Ibizamini
Ibipimo bya tekiniki yiki gitabo ukurikije uburyo bwo gupima GY / T 194-2003
1. Shiraho 59 PAL-D igereranya ya tereviziyo ya televiziyo ku ntera ya 45 / 87MHz ～ 550MHz munsi yo gutakaza umurongo. Kohereza ibimenyetso bya modulasi ya digitale ku ntera ya 550MHz ～ 862 / 1003MHz, urwego rwo kwerekana ibimenyetso bya digitale (muri 8 MHz umurongo wa interineti) ni 10dB munsi y'urwego rutwara ibimenyetso bisa. Iyo kwinjiza optique imbaraga za optique yakira ni -2dBm, urwego rwa RF rusohoka ni 108dBμV, hamwe na 9dB ibisohoka bigoramye, bapima C / CTB, C / CSO, na C / N.
.
Icyitonderwa: Iyo igipimo cyasohotse gisohoka ni sisitemu yuzuye iboneza kandi imbaraga zo kwakira optique ni -2dBm, ibikoresho byujuje urwego ntarengwa rwo gusohoka rwerekana urutonde. Iyo iboneza rya sisitemu rigabanutse (ni ukuvuga imiyoboro nyayo yohereza igabanuka), urwego rwibikoresho biziyongera.
Icyitonderwa cyinshuti: Tanga igitekerezo cyo gushyira ikimenyetso cya RF kuri 6 ~ 9dB igabanutse mugisohoka mubikorwa byubwubatsi kugirango utezimbere umurongo utari umurongo (munsi yumutwe) wa sisitemu ya kabili.
