GFH1000-K FTTH CATV receiver with WDM to ONU
GFH1000-K is 1550nm CATV fiber to the home optical receiver with 1310nm/1490nm WDM loop out port. After fiber deep campaign, HFC CATV optical receiver serving area decreases from 2000 subscribers, to 500 subscribers, 125 subscribers, 50 subscribers and now one subscribers when fiber to the home. Since the internet function is transferred to GPON or XGPON, GHF1000-K has 45MHz to1000MHz or 1218MHz full RF bandwidth for TV broadcasting service.
GFH1000-K has one optical input port, one fiber wdm port, one 12V DC power input and one RF output. Like ONU family devices, GFH1000-K has flame retarding plastic housing with internal sheet metal housing to ensure the RF isolation and performance.
With built-in AGC design, GFH1000-K is a plug and play device easily installed at home or SOHO application. It has high linearity photodiode and low noise GaAs amplifier, outputs high quality RF for either analog TV or digital QAM TV for one or more TV sets in one family. The 1550nm optical input power can be as low as -15dBm when the RF signal is DVB-C QAM or -8dBm when the RF signal is analog TV. The RF port has surge protection and the RF output level can be adjustable if the MGC option is activated.
The input 1550nm signal bandwidth can be 1525nm~1565nm wideband optical signal and narrow band 1550nm~1560nm optical signal. The WDM can support regular 1310nm/1490nm GPON or 1270nm/1577nm XGPON or NGPON2. GFH1000-K can enable Greatway ONU or any third party ONU with RF function for broadcasting RF channels.
