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…

It requires 2 fibers for forward and return path communications, and every node has its own RPR. That is certainly manageable IF you have the fiber and RPRs, but it can be more efficient. 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.

It can support MDU installations as well with up to 64 CPE devices (STB and/or cable modem) per MicroNode. Depending upon the number of endpoints and distance, traditional RF amplifiers can be added to distribute services as needed. Again, using Alloptic does not disrupt current practices.

MicroNode Transmitter Burst Timing Ramp-Up Phase Preamble Cable Modem Transmission MicroNode Transmission 220nS into the Ramp Up Phase, the MicroNode laser transmitter begins to turn on. It reaches “on” state 1.0 μS later. Total response time =1.22 μS ~200nS shift between signals due to delays of MicroNode + optical cable + laser detector 1.0 μS 220 nS 220 nS into the Ramp Up Phase, the MicroNode laser transmitter begins to turn on Laser reaches “on” state 1.0 uS later Total response time = 1.22 uS

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

Downstream Channel Lineup fiber + splicing + connectors Downstream Levels (1550nm) Downstream Channel Lineup 1550nm signal is OK 0.0dBm to -6.0dBm is good +3dBm +21dBm 2.6dBm -5.9dBm 1550nm Laser Transmitter EDFA +19.6dBm Drop fiber MicroNode +6dBm Return Receiver To CMTS / STB Controller WDM Cassette 1x32 Splitter 8.5dB loss for fiber + splicing + connectors [animation required for this slide to work] And here is how you do it. Once the MicroNode structure is in place, it is simple to enable guaranteed bandwidth (SLA-quality) services to all those businesses the network is passing. First click - Make use of the open ports available. Second click – drop in an OLT 3rd click – connect that unused splitter port at the node to an ONT and start delivering those business services 4th click – if the MicroNode is closer to the business, use the available port from that point. Makes great sense in metropolitan applications were both businesses and residents share a building It is really that easy to create a business service distribution network. Of course we don’t want to trivialize the other work that must be done to turn on business services, but with this approach the infrastructure is not a limiting factor.

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

Reality is that CMTS systems do not support the class of service/guaranteed bandwidth/SLA-quality capabilities needed to compete in the lucrative business service market. To compete, you must offer guaranteed bandwidth and performance tailored to specific business needs. Here are key business services that deliver significant bottom-line dollars to carriers. Alloptic enables you to offer all of those from a single PON infrastructure.

Backhaul Applications Alloptic Has Extended the Definition of PON Beyond residential to a complete services network Support for MDU/MTU subscribers Support for SLA-quality business services Support for Backhaul applications Backhaul requirements High bandwidth from a single point Alloptic delivers up to 1Gbps from a single ONT TDM services: Low Latency/Jitter T1/E1 Alloptic has patented TDM technology to transport TDM without the latency and other concerns with circuit emulation Ability to support multiple services from a single ONT Ethernet & T1/E1 TDM Interfaces Multiple Ethernet ports for backhaul and/or other services Video Surveillance Environmental & Intrusion Alarms Equipment telemetry Alloptic is changing the meaning of PON in the access network. Traditionally it has meant only residential service. With Alloptic PON can now encompass high density MDU/MTU, business services for voice and data, security applications (covered in a separate presentation), and backhaul. Alloptic has the only system available with up to 1 Gbps symmetrical bandwidth per PON that also has a patented TDM transport. That means ALL services to ALL subscribers over a SINGLE network system using a SINGLE fiber Whether TDM or VoIP voice services, E1/T1, best-effort or SLA-quality data, or video using RF and/or IP, Alloptic supplies the network.l

Cellular Backhaul – Up to 10 x T1/E1 Communications Network DS3 or OC3 to PSTN Security Monitoring BTS PON/ONTs Up to 10 T1/E1 Ethernet GEPON OLT Core Network Optical Splitter Multiport ONT Ethernet Ethernet Alarm Panel Security Environmental Power For backhaul of E1/T1 services such as those typically found in cellular backhaul, the biz200 ONT is a perfect solution. It supports up to 10 E1/T1 circuits which are then available from the DS3 ports of the edge2000 OLT. In some applications multiple cell service providers have services at the same cell site. edge2000 capabilities include full 3-1-0 cross-connect functions, allowing the user to groom E1/T1 circuits as needed for various. That means the network operator can backhaul cell services for all the service providers over one single network, giving them isolation and secuirty even though they are transported over a single system. For applications requiring more than 10 E1/T1 circuits a multiplexer can combine the E1/T1 circuits into a DS3 for transport as shown on the second page following.
