  • Stay Competitive - Most think of defending against MSO’s and other ILECs, but fiber also provides an offensive weapon for disrupting the competitive landscape. - e.g. – 30 mbps symmetric service will disrupt any data service offering available from the MSO - e.g. – Providing a large number of HDTV channels differentiates video service from Satellite, and inband interactive IP services (VOD, gaming, etc.) differentiates the data/video service from MSOs. Future Needs - Copper deployed today will have to be pulled out in the next 5 years to remain competitive - independent of loop length Unlimited Service via new infrastructure - Build a network that eclipses the competition Operational Cost Reduction - Both upfront cost (OSP – power, battery, etc.) and long term costs (maintenance, provisioning, service expandability, etc.)
  • This shows a more detailed look at the components in the RF overlay network. The RF signal is converted from an RF Electrical signal to an optical signal by a transmitter at the video headend. This signal will need to have high signal power at the ONT, for the analog cable to maintain a sufficiently high Carrier to Noise ratio (CNR). Thus, the signal is amplified with an erbium doped fiber amplifier (EDFA) before being combined with the data and voice signal from the AccessMAX OLT. The combined signal is sent to ONTs at the subscriber, where the RF signal is transmitted over a coax connection to the TVs in the home. If interactive video services are planned, an RF adapter will be used in conjunction with the ONT. We will go over home wiring and ONTs in the next part of this module.
  • Long version of the bullets: Voice Network Interfaces Integrated to the OLT: GR-303, TR-08, V5…as well as TR-57 if needed, all already homologated with key customers Voice solution flexible to evolve to any network architecture: from a traditional TDM (GR-303, TR-08, V5) to NGN packetized voice (H.248, MEGACO, VoIP) Flexible OLT configurations, with low start-up cost, covering few dozens homes to hundreds Hardened OLT for deployment in a cabinet: solves fiber count availability and reach issues ONT solutions covering SFH to MDU and MTU End to End managed solution, with Panorama already established with some key customers And then all the AFC corporate strengths
