FTTP FTTP SolutionsSolutions
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…

Nodes of 100 - 400 homes with 4 coax trunks
Return Path 1310 nm
Requires separate fibers for forward and return paths Every node requires a return path receiver in the hub Doesn’t provide upstream ingress or impulse noise
suppression All node users share the 4 upstream channels used for
cable modem data service, voice traffic, etc.

Coaxial CableFiber
RFoG transceivers must be temperature hardened (-40C to +65C) RF signal quality can be amplified for coax distances and splits RF signal levels upstream and downstream must be considered when
engineering the RF amplifiers and coax cable distances. Shared users greatly reduces the cost per user

Optical Optical Budget Budget ConsiderationConsiderationss 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
