GFH1000-K FTTH CATV inogamuchira ine WDM kuenda kuONU
Product Description
GFH1000-K ndeye 1550nm CATV faibha kune imba yekugamuchira yekuona ine 1310nm/1490nm WDM loop panze port. Mushure memushandirapamwe wefiber yakadzika, HFC CATV optical receiver service inodzikira kubva 2000 vanyoreri, kusvika 500 vanyoreri, 125 vanyoreri, 50 vanyoreri uye iye zvino mumwe vanyoreri kana faibha kuenda kumba. Sezvo basa reinternet richiendeswa kuGPON kana XGPON, GHF1000-K ine 45MHz kusvika1000MHz kana 1218MHz yakazara RF bandwidth yeTV nhepfenyuro.
GFH1000-K ine one optical input port, one fiber wdm port, one 12V DC power input uye imwe RF inobuda. Kufanana nemidziyo yemhuri yeONU, GFH1000-K ine murazvo unodzoreredza imba yepurasitiki ine mukati pepa simbi imba kuti ive nechokwadi chekuzviparadzanisa neRF uye kuita.
Iine yakavakirwa-mukati AGC dhizaini, GFH1000-K ipuragi uye mudziyo wekutamba unoiswa zviri nyore kumba kana SOHO application. Iyo ine yakakwira mutsara photodiode uye yakaderera ruzha GaAs amplifier, inoburitsa yakakwira mhando RF yeanalog TV kana yedhijitari QAM TV yeimwe kana anopfuura eTV seti mumhuri imwe. Iyo 1550nm optical yekupinza simba inogona kudzikira se -15dBm kana iyo RF siginecha iri DVB-C QAM kana -8dBm kana iyo RF siginecha iri analog TV. Iyo RF chiteshi ine kuchengetedzwa kwekuvhiya uye iyo RF yekubuda nhanho inogona kuchinjika kana iyo MGC sarudzo ikamiswa.
Iyo yekuisa 1550nm chiratidzo bandwidth inogona kuva 1525nm ~ 1565nm wideband optical chiratidzo uye nhete bhendi 1550nm ~ 1560nm chiratidzo chemaziso. WDM inogona kutsigira 1310nm/1490nm GPON kana 1270nm/1577nm XGPON kana NGPON2. GFH1000-K inogona kugonesa Greatway ONU kana chero yechitatu bato ONU ine RF basa rekutepfenyura RF chiteshi.
Zvimwe Zvimiro:
• Murazvo wepurasitiki wakasungirirwa mudzimba.
• High Linearity Photodiode yeCATV RF.
• 45~1000MHz (yakadzika) RF Output (45~1218MHz sarudzo).
• Optical AGC range: -10dBm ~ 0dBm.
• Optional MGC range: 0~15dB.
• 1310nm/1490nm Optical Bypass Port kuenda kuONU.
• WDM inogona kuvandudzwa kuti ibatanidze 1270nm/1577nm reflection port yeXGPON ONU.
• DC Simba uye optical input LED chiratidzo.
• 12V DC simba adapta.
