Worldwide gigabit passive optical network (GPON) deployments continue to be the dominant choice for network infrastructures today. Hundreds of service providers across North America and& Globally are deploying GPON for residential and business applications. Service Providers that are adopting the technology include independent telephone companies, competitive local exchange carriers (CLEC’s), municipalities and – a most recent trend – Cable Operators.
Over the past few years, cable operators have emerged as viable competitors in business services delivery. Revenues from business customers are an increasing percentage of MSOs’ top-line numbers and a helpful addition to their bottom lines, since margins of business services exceed those of residential services. Cable operators have used various technologies to deliver these services, with several MSO’s using PON-based platforms to deliver a wide range of services. Cable operators who have deployed GPON services to businesses have enjoyed robust growth, as it enables them to offer a wide range of services at very low cost. Cable operators have now begun to examine different iterations of PON to supply new Video options and cut future network costs even further.
The iPhotonix CATV Hardware and Software Solutions allows MSO’s via our RF Overlay & RF Return Solutions to remove the coaxial cable requirement almost completely from the network (except inside the customers’ homes). Operators viautilizing the iPhotonix RF Overlay and RF Return solutions can deploy a full GPON System virtually in one device. The solution enables the operator to turn on and off Cable Service from the existing billing system, whereas the legacy system supplies it in two systems. This solution provides sharper and clearer picture because there is no active equipment between the head-end and the ONT at the customer premise. The VOD and Pay-Per-View speeds are a lot faster to communicate back to the Head-eEnd because the return is via the PON. These are just a few of contributing attributes for GPON that have compelled MSO operators to consider deploying GPON for their new and existing service offerings.
The iPhotonix Solutions-
The iPhotonix Outdoor GPON ONT with CATV supports up to two 10/100/1000 Base-T interfaces for high-speed Ethernet via a CAT-5 Ethernet cable between the ONT and a home router. The Ethernet interface operates as an IEEE 802.1d transparent bridge based on RFC-2684. Class of service as well as bandwidth is controlled through provider provisionable options. The Ethernet port supports streaming IP video and IPTV content delivery and meets ITU 802.1p QoS standards at the MAC level. The iPhotonix oOutdoor/indoor GPON ONT with CATV supports CATV applications via a coaxial F-connector. This interface serves as primary protection for the video and is capable of handling a 1000 Amp fault current in the shield. The CATV interface contains a forward path video receiver (CATV – 54 MHz to 1 GHz) with sensitivity up to -9 dB, supports multiple gain stages, AGC and status indications, video power on/off control and AGC gain control. The CATV interface also supports the upstream data channel from set-top boxes.
- Packet based interactive IPTV services including multicast video and video-on-demand
- RF Video with integrated RF Return supporting the 8 to 30 MHz return path frequency band
- An iPhotonix head-end RF modulator is available for upstream data return channels.
