Incamake ngufi
SR812ST(R) niyo receiver yacu ya CATV network optique igezweho ifite ubushobozi bwo gutanga umusaruro mu buryo bwo hejuru. Pre-amplifier ikoresha full-GaAs MMIC, post-amplifier ikoresha module ya GaAs. Igishushanyo mbonera cya serivise nziza hamwe n'uburambe bwacu bw'imyaka 10 mu gushushanya, bituma ibikoresho bigera ku mikorere myiza. Kugenzura microprocessor, kwerekana parameters kuri digitale, no gukemura ibibazo by'ubwubatsi biroroshye cyane. Ni cyo gikoresho cy'ingenzi cyo kubaka umuyoboro wa CATV.
Ibiranga Imikorere
- Umuyoboro w'amashanyarazi uhindura PIN utanga igisubizo cyinshi.
- Imiterere myiza y'uruziga, gukora SMT, n'inzira nziza y'ibimenyetso bituma uburyo bwo kohereza ibimenyetso by'amashanyarazi burushaho kuba bwiza.
- Chip yihariye yo kugabanya RF, ifite uburyo bwiza bwo kugabanya RF n'umurongo ugororotse, ifite ubuziranenge bwo hejuru.
- Igikoresho cyo kongera ingufu cya GaAs, gitanga ingufu inshuro ebyiri, gifite inyungu nyinshi kandi kikagira ubusumbane buke.
- Ibikoresho byo kugenzura bya Single Chip Microcomputer (SCM) bikora, LCD igaragaza ibipimo, uburyo bworoshye bwo gukora no kwihuta, hamwe n'imikorere ihamye.
- Imikorere myiza ya AGC, iyo ingufu z'amashanyarazi yinjiye ari －9～＋2dBm, urwego rw'umusaruro ruguma rudahinduka, naho CTB na CSO muri rusange ntibihinduka.
- Ikoranabuhanga ryo gutumanaho ryihariye, rishobora guhuzwa na porogaramu yo gusubiza ibibazo mu gucunga umuyoboro wa interineti yo mu cyiciro cya Ⅱ, no kugera kuri sisitemu yo gucunga umuyoboro wa interineti.
- Isohora ry’amashanyarazi rishobora guhitamo uburyo bwo guturika kugira ngo rigabanye cyane urusaku ruhurirane kandi rigabanye umubare w’akira imbere.

Ibipimo bya tekiniki by'iyi nyandiko hakurikijwe uburyo bwo gupima bwa GY/T 194-2003
1. Igice cyo kwakira urumuri rw'imbere: gifite fibre isanzwe ya optique ya kilometero 10, attenuator idakoresha optique, na transmitter isanzwe ya optique byagize umurongo wo gupima. Shyira ikimenyetso cya 59 cya PAL-D analog TV channel ku ntera ya 45/87MHz～550MHz munsi y'igihombo cyagenwe cy'umurongo. Kohereza ikimenyetso cya digitale modulation ku ntera ya 550MHz～862/1003MHz, urwego rwa digitale modulation signal (muri bandwidth ya 8 MHz) ruri munsi ya 10dB ugereranije n'urwego rwa analog signal carrier. Iyo imbaraga za optique zinjiye za optique receiver ari -2dBm, urwego rwa RF output ni 108dBμV, hamwe na 9dB output tilt, pima C/CTB, C/CSO, na C/N.
2. Igice cyo kohereza amakuru y'inyuma: Ubugari bw'amakuru n'uburyo bwo guhindura amakuru bwa NPR ni ibipimo by'amakuru bigizwe n'agasanduku k'amakuru gasubiza amakuru inyuma n'agasanduku k'amakuru gasubiza amakuru inyuma.
Icyitonderwa: Iyo urwego rw'umusaruro rugenwe ari imiterere yuzuye ya sisitemu kandi imbaraga za optique zikira ari -2dBm, ibikoresho byujuje urwego ntarengwa rw'umusaruro w'ikimenyetso cy'umuyoboro. Iyo imiterere ya sisitemu igabanutse (ni ukuvuga ko imiyoboro nyayo yo kohereza igabanuka), urwego rw'umusaruro w'ibikoresho ruzazamuka.
Itangazo ryiza: Ugomba gushyiraho ikimenyetso cya RF kuri 6 ~ 9dB tilt output muri porogaramu y’ubuhanga ifatika kugira ngo wongere index idahindagurika (munsi y’agace) ka sisitemu y’insinga.
