GWR3300 Quad soo celinta Jidka soo celinta
Sharaxaada Alaabta
GWR3300 rack mount soo celinta dariiqa soo celinta waxaa loogu talagalay gudaha gudaha CATV soo celinta signalka. 19 "1RU rack, waxaa jira ugu badnaan 4 madax-bannaan oo soo celinta dariiqa soo celinta, kuwaas oo ka hela calaamadaha soo noqnoqda ee noodhka indhaha haddii ay dhacdo fiber ilaa dhismaha ama afar shabakad PON haddii ay dhacdo fiber guriga. Soo-qaade kastaa wuxuu leeyahay qaylo yar oo PIN diode ah, preamplifier GaAs, shaandhaynta ka gudubka band hooseeya iyo cod-weyneeye heer sare ah oo RF ah, oo siinaya ilaa 45dBmV heerka wax soo saarka ee 19” 1RU gadaasha dambe. Diode-ka PIN-ku wuxuu taageeraa 1260nm ~ 1650nm hirarka mowjadda aragga, oo ay ku jiraan 1310nm caanka ah, 1550nm iyo kanaalada kale ee CWDM. Dhinaca hore, waxaa jira hal -20dB RF deked tijaabo ah iyo hal attenuator oo joogto ah oo la hagaajin karo ee qaataha kasta, taas oo awood u siinaysa dejinta fudud ee waddo kasta oo soo laabasho ah heerka wax soo saarka RF. Baaxadda qaade kasta oo soo laabasho ah waa 5MHz ~ 204Mhz, oo u dhiganta noodhka indhaha RF qaybinta 42/54MHz, 65/85MHz, 85/102MHz, 204/258MHz, taageeraya Docsis 2.0, Docsis 3.0 iyo Docsis 3.1 cable modem kor u socodka RF. Si kale haddii loo dhigo, GWR3300 waxay la macaamili kartaa dhammaan calaamadaha kor u kaca ee CATV, iyada oo aan loo eegin noodhka indhaha ama RFoG micronodes.
Marka laga soo tago afarta dariiqo ee madax-banaanida soo celinta wax soo saarka RF, waxaa jira hal deked oo RF ah oo isku daraysa afar wax soo saar oo ah hal wax soo saar RF ah, kaas oo ku habboon isku xirka dekedaha CMTS.
Iyada oo leh wax qabad sare oo photodiode ah iyo cod-weyneeye isku-dhafan, GWR3300 waxay siisaa koox waddo soo celin nadiif ah oo loogu talagalay calaamadaha kor-u-socodka Cable Modem. Tilmaamaha korantada indhaha iyo dekedda tijaabada RF ee ku taal dhinaca hore ayaa muujin kara heerka qaataha.
Sifooyin kale:
• 1550nm/1310nm laba mawjadaha dhererka.
• 4 RPR madax banaan oo ku jira hal 19" 1U rack caadiga ah.
• Qaylo hoose, photodiode toosan oo sarreeya.
• 5-204 MHz RF Bandwidth.
• Laba baas filtarrada si ay u niyad jabiyaan dhawaaqa kor u socda.
• Isku hagaajinta wax soo saarka iyo -20dB RF tijaabada ah oo laga heli karo guddiga hore.
