SR812ST(R) jẹ titun ga-giga meji-jade CATV nẹtiwọki olugba opitika. Ampilifaya iṣaaju gba GaAs MMIC ni kikun, ampilifaya ifiweranṣẹ gba module GaAs. Apẹrẹ iyika iṣapeye pọ pẹlu awọn ọdun 10 wa ti iriri apẹrẹ ọjọgbọn, jẹ ki ohun elo naa ṣaṣeyọri awọn atọka iṣẹ ṣiṣe to dara. Iṣakoso Microprocessor, ifihan oni-nọmba ti awọn aye, n ṣatunṣe aṣiṣe jẹ irọrun paapaa. O jẹ ohun elo akọkọ lati kọ nẹtiwọki CATV.
Awọn abuda iṣẹ
- Ga esi PIN photoelectric iyipada tube.
- Apẹrẹ iyika iṣapeye, iṣelọpọ ilana SMT, ati ọna ifihan iṣapeye jẹ ki gbigbe ifihan agbara fọtoelectric diẹ sii dan.
- Chirún attenuation RF pataki, pẹlu attenuation RF ti o dara ati laini iwọntunwọnsi, deede giga.
- Ẹrọ ampilifaya GaAs, iṣelọpọ agbara ni ilopo meji, pẹlu ere giga ati ipalọlọ kekere.
- Chip Microcomputer Nikan (SCM) ohun elo iṣakoso ti n ṣiṣẹ, LCD ṣafihan awọn aye, irọrun ati iṣẹ inu, ati iṣẹ iduroṣinṣin.
- Iṣe AGC ti o dara julọ, nigbati sakani agbara opitika titẹ sii jẹ -9～＋2dBm, ipele iṣelọpọ ntọju ko yipada, ati CTB ati CSO ni ipilẹ ko yipada.
- Ni wiwo ibaraẹnisọrọ data ipamọ, le sopọ pẹlu kilasi Ⅱ oludahun iṣakoso nẹtiwọọki, ati iraye si eto iṣakoso nẹtiwọọki.
- Ijadejade ipadabọ le yan ipo ti nwaye lati dinku isọpọ ariwo ati dinku nọmba olugba iwaju.
Ọna asopọ Awọn ipo Idanwo
Awọn paramita imọ-ẹrọ ti itọnisọna yii ni ibamu si ọna wiwọn ti GY/T 194-2003
1. Siwaju opitika gba apakan: pẹlu 10km boṣewa opitika okun, palolo opitika attenuator, ati boṣewa opitika Atagba kq awọn igbeyewo ọna asopọ. Ṣeto 59 PAL-D ifihan agbara ikanni afọwọṣe TV ni iwọn 45/87MHz～550MHz labẹ ipadanu ọna asopọ pato. Gbigbe ifihan agbara awose oni nọmba ni iwọn 550MHz～862/1003MHz, ipele ifihan agbara awose oni nọmba (ni bandiwidi 8 MHz) jẹ 10dB kekere ju ipele afọwọṣe ifihan agbara lọ. Nigbati agbara opiti titẹ sii ti olugba opiti jẹ -2dBm, ipele ti o wu RF jẹ 108dBμV, pẹlu titẹ iṣanjade 9dB, wiwọn C/CTB, C/CSO, ati C/N.
2. Abala atagba opitika sẹhin: Ipin ọna asopọ ati iwọn agbara NPR jẹ awọn atọka ọna asopọ eyiti o jẹ atagba atẹhin sẹhin ati olugba opiti sẹhin.
Akiyesi: Nigbati ipele ti o wu jade jẹ iṣeto ni kikun ti eto ati gbigba agbara opitika jẹ -2dBm, ohun elo naa pade ipele ti o ga julọ ti atọka ọna asopọ. Nigbati iṣeto eto ba dinku (iyẹn ni, awọn ikanni gbigbe gangan dinku), ipele iṣelọpọ ti ẹrọ yoo pọ si.
Akiyesi Ọrẹ: daba pe o ṣeto ifihan agbara RF si 6 ~ 9dB titẹ titẹ sita ninu ohun elo imọ-ẹrọ ti o wulo lati mu itọka ti kii ṣe laini dara si (labẹ ipade) ti eto okun.
