Umuyoboro w'amajwi wo hanze wa 1550nm
Iyi serivise y’itumanaho ry’imbere ikoresha uburyo bwa "internal-modulated transmitter" ihindura ibimenyetso bya RF-to-optical mu buryo bwa "transmission link" bwa 1550nm.
Agasanduku gasanzwe ka 1U 19' gafite ikimenyetso cy'ubururu bw'amazi (LCD/VFD) imbere;
Ingano y'umuvuduko: 47—750 / 862MHz;
Ingufu zisohoka kuva kuri 4 kugeza kuri 24mw;
Urusobe rwo gukosora mbere yo kugoreka;
AGC/MGC;
Igenzura ryikora ry'ingufu (APC) n'igenzura ryikora ry'ubushyuhe (ATC).
Ikiranga Modulator yo hanze na laser byombi bitumizwa muri Leta Zunze Ubumwe za Amerika cyangwa mu Buyapani.
Uburyo bwiza bwo kuzunguruka mbere yo kugoreka butuma CTB na CSO biba byiza iyo CNR iri ku rwego rwo hejuru.
Ifite uburyo bwo gufunga neza bwa SBS kandi ikanahindura SBS muri 13, 16, 18, ikwiriye ubwoko butandukanye bwa CATV net.
Igenzura rya AGC.
Ingufu ebyiri z'imbere zishobora guhindurwa mu buryo bwikora.
Gugenzura ubushyuhe mu buryo bwikora.
Porogaramu ya microprocessor y'imbere ifite akazi ko kugenzura laser, kwerekana parametre, kuburira amakosa, gucunga net n'ibindi. Iyo parametre ikora ya laser ivuye ku gaciro kadahinduka ka porogaramu, imashini izaburira.
Iyi transmitter itanga umurongo ngenderwaho wa RJ45 na RS232 wo guhuza mudasobwa no kuyikurikirana.
Igipimo cya tekiniki
Ibintu Ishami Ibipimo bya tekiniki Ingufu z'amashanyarazi zisohoka dBm 3 4 5 6 7 8 9 10 Uburebure bw'urumuri rw'izuba nm 1550±10 cyangwa uburebure bwa ITU Ubwoko bwa Lazeri DFB Laser Uburyo bwo Guhindura Ishusho mu Ijwi Guhindura Ingufu mu buryo butaziguye Ubwoko bw'umuhuza w'urumuri FC/APC cyangwa SC/APC Ingano y'Inshuro MHz 47~862 Urwego rwo kwinjira dBμV 72~88 Ubushyuhe mu itsinda dB ± 0.75 Impedansi yo kwinjira Ω 75 Igihombo cyo kugarura ibyakoreshejwe dB ≥ 16 (47~550)MHz; ≥ 14 (550~750/862MHz) C/CTB dB ≥ 65 C/CSO dB ≥ 60 C/N dB ≥ 51 Urubuga rugenzurwa na AGC dB ± 8 Ingano igenzurwa na MGC dB 0~10 Ingufu z'amashanyarazi V AC 160V~250V (50 Hz) Ikoreshwa ry'ingufu W 30 Ubushyuhe bwo gukora ℃ 0 ~+45 Ubushyuhe bwo kubika ℃ -20 ~ +65 Ubushuhe bugereranye % Nta gushyuha cyane kuri 95% Ingano mm 483(L)X 380(W)X 44(H)
