Ile-iṣẹ titun giga-opin mẹrin-jade CATV nẹtiwọki olugba opitika SR814ST, iṣaju-ampilifaya nlo GaAs MMIC ni kikun, ati ampilifaya ifiweranṣẹ nlo awọn modulu GaAs. Pẹlu apẹrẹ Circuit iṣapeye ati awọn ọdun 10 ti iriri apẹrẹ ọjọgbọn, ẹrọ naa ti ṣaṣeyọri awọn afihan iṣẹ ṣiṣe to dara julọ. Ni afikun, iṣakoso microprocessor ati ifihan paramita oni nọmba jẹ ki n ṣatunṣe aṣiṣe ẹrọ rọrun pupọ. O jẹ ohun elo akọkọ pataki fun kikọ nẹtiwọki CATV.

Olugba opitika nẹtiwọọki CATV wa ti o ni ilọsiwaju SR814ST gba idahun giga-idahun PIN photoelectric tube iyipada, iṣapeye apẹrẹ Circuit ati iṣelọpọ ilana SMT, ati pe o rii didan ati gbigbe daradara ti awọn ifihan agbara fọtoelectric.
Awọn eerun attenuation RF ti o ṣe iyasọtọ pese idinku laini deede, lakoko ti awọn ẹrọ ampilifaya GaAs pese ere giga ati ipalọlọ kekere. Eto naa jẹ iṣakoso nipasẹ microcomputer chip kan (SCM), pẹlu awọn aye ifihan LCD, iṣẹ ti o rọrun ati ogbon inu, ati iṣẹ iduroṣinṣin.
Eto AGC ṣe idaniloju pe ipele ti o wu jade wa ni igbagbogbo lori iwọn agbara opitika ti -9 si +2 dBm pẹlu kikọlu kekere lati CTB ati CSO. Eto naa tun pẹlu wiwo ibaraẹnisọrọ data ti a fi pamọ, eyiti o le sopọ si iru oludahun iṣakoso nẹtiwọọki II ati ti o ni asopọ si eto iṣakoso nẹtiwọọki.Gbogbo awọn iṣiro imọ-ẹrọ ni iwọn ni ibamu si GY / T 194-2003, labẹ awọn ipo idanwo idiwọn.
