GWR3300 Kwakira Inzira Yakira
Ibisobanuro ku bicuruzwa
GWR3300 rack mount yo kugaruka inzira yakira yagenewe kubakira CATV yo murugo. Muri rack ya 19 ”1RU, hari ntarengwa 4 yigenga yo kugaruka inzira optique yakira, yakira inzira yo kugaruka inzira ya optique kuva kuri optique yacu mugihe habaye fibre yinyubako cyangwa umuyoboro wa PON ine mugihe fibre ijya murugo. Buri cyakira gifite urusaku ruke rwa PIN diode, GaAs preamplifier, bande ya pass pass ya filter hamwe nu rwego rwo hejuru rwa RF amplifier, itanga urwego rusohoka rwa 45dBmV kurwego rwa 19 "1RU. PIN diode ishyigikira 1260nm ~ 1650nm ya optique yumurongo wa optique, harimo 1310nm izwi cyane, 1550nm nizindi miyoboro ya CWDM. Kuruhande rwimbere, hari icyambu kimwe -20dB RF hamwe nicyuma kimwe gihoraho gishobora guhindurwa kuri buri cyakira, bigatuma byoroha gushiraho buri nzira yo kugaruka RF isohoka urwego. Umuyoboro mugari wa buri nzira yo kugaruka ni 5MHz ~ 204MHz, uhuye na optique node ya bande ya RF igabanyamo 42 / 54MHz, 65 / 85MHz, 85 / 102MHz, 204 / 258MHz, ishyigikira Docsis 2.0, Docsis 3.0 na Docsis 3.1 kabili modem yo hejuru ya RF ibimenyetso. Muyandi magambo, GWR3300 irashobora guhangana nibimenyetso byose bya CATV hejuru, ntakibazo cyaba optique cyangwa micronode ya RFoG.
Usibye inzira enye zigenga kugaruka RF isohoka, hari icyambu kimwe cya RF gihuza ibisubizo bine byakira nkibisohoka kimwe bya RF, bikaba byoroshye guhuza CMTS yo muri Amerika.
Hamwe nimikorere yo hejuru ya fotodiode hamwe na amplifier ya Hybrid, GWR3300 itanga inzira nziza yo kugaruka kumurongo wa Cable Modem up-streaming signal. Icyerekezo cyerekana ingufu hamwe nicyambu cya RF kumwanya wambere urashobora kwerekana uko uwakiriye ameze.
Ibindi biranga:
• 1550nm / 1310nm uburebure bubiri.
• 4 yigenga RPR muri imwe 19 ”1U isanzwe.
• Urusaku ruke, umurongo muremure wa fotodiode.
• 5- 204 MHz RF Umuyoboro mugari.
• Bande ebyiri zungurura muyungurura kugirango ugabanye urusaku rwinshi.
• Guhindura ibisohoka hamwe na -20dB RF ikizamini kiboneka kumwanya wambere.
