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…

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.

A single fiber supports both forward and return path
One return path receiver can be shared by many MicroNodes
Transceiver must operate in “Burst Mode”
 Upstream laser is turned on only during an RF burst from the cable modem or STB
 Ingress and impulse noise is substantially reduced or eliminated entirely
 Facilitates

Fiber
 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 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
25.5dB
Alloptic, Inc. Proprietary
fiber distance loss - 20Km @ .22dB / Km = 4.4dB
loss budget downstream and 25.5 db loss upstream

Why Gigabit Ethernet?
 High-speed technology
 Ideal platform for Internet Protocol (IP)
 Ethernet offers best price/performance
 Market leader in computer data networking
 Costs distributed over large & competitive market
 Creates a continuous decline in costs & improved performance
(10,100,1000,10000Mbs)
 Other PON architectures can not keep up
 No provisions for anything beyond 2.5Gbps

In Summary…
 RFoG – Cost effective alternative to HFC for FTTP
while requiring no changes to existing back office
systems and CPE
 GEPON – A true Ethernet switching system that makes
it inherently well suited for the delivery of IP and Legacy
services…not simple transport
 Hybrid – Shares the same Outside Plant for Business,
MDU and Residential services
 Field proven, available today!
