FTTP Solutions • RFoG & GEPON technologies use industry standard Passive Optical Network (PON) architectures (Minimum requirements = 20Km reach with 32 splits) • For an end-to-end solution, a complete suite of Head End / Hub and customer premise equipment is necessary • This enables Service Providers to provide triple-play services that include: • IP and/or TDM voice • IP and/or RF video • HSIA and/or B2B LAN Interconnect • Other Ethernet-based capabilities include: • Security: alarm monitoring, video surveillance, etc… • Backhaul: Cell Towers, WiFi/WiMax, etc… • Harsh environments: Marinas, Seaside & Mountain resorts, etc…

Cable Modem • MicroNode senses burst; turns on laser for duration of data • Cable modem sends burst of data STB Core Network • RPR receives data; sends it to CMTS Burst Mode Operation • CMTS schedules the Cable Modem to transmit data Laser Transmitter EDFA 1 MicroNode 1550nm WDM MicroNode Splitters Video/RF Feed RPR CMTS MicroNode 1310nm n • CMTS proceeds to next scheduled device

Optical Budget Considerations • For optimum future growth • RFoG networks should be designed for PON compatibility • ITU and IEEE PON standards focus on 20Km / 32 splits per fiber • Allows future applications using CWDM or DWDM wavelengths on the same fiber network • 26dB optical budget supports most configurations with… • Connectors • 32 splits • 20Km reach • Typical loss parameters for MicroNode fiber plant: 17.0dB splitter budget for 32 splits is standard 2.4dB for connector losses at 6 points (.4db / connector) 0.2dB for fusion splicing at 6 splice locations 1.5dB for 1590nm WDM coupler (1.4dB downstream @ 1550nm) 21.1dB total for splitter, splicing, connectors, WDM 4.4dB fiber distance loss - 20Km @ .22dB / Km = 4.4dB 25.5dB loss budget downstream and 25.5 db loss upstream
