CDX Ericsson CATV/DBS Transceiver

The Deep Fiber FTH architecture is a single fiber optic cable that terminates in the home at a wall-mounted, optical electrical converter (OEC). The OEC accommodates multiple carrier-class telephone lines, a 10BaseT Ethernet connection, and multi-channel CATV (community antenna television) and direct broadcast satellite (DBS) video hookups. Unlike other systems, Deep Fiber FTH allows homeowners to utilize currently available equipment and supports multiple DBS hookups over a single cable. The OEC includes a battery backup that provides power to maintain essential services during power failures.

Central office components include Marconi's DISC*S(R) NGDLC, the DS1 voice feeder that provides an interface for Universal, INA, TR-08 and GR-303 modes of operation. Voice and data feeds entering the CO are combined on Marconi's DISC*S MX Distribution Shelf (MDS), each of which supports a total of 672 telephone lines and 896 simultaneous internet sessions. Marconi's Quad Optical Interface Units (QOIUs) in the MDS deliver voice and data services bi-directionally. These components enable service providers to add capacity incrementally to meet future demand without infrastructure changes. Voice and data traffic from the MDS then feeds into Marconi's Splitter WDM Frame (SWFX) for distribution over the Passive Optical Network (PON) to the curbside Passive Optical Splitter (POS.)

CATV and DBS video signals entering the central office are combined by Marconi's CATV/DBS Transceiver (CDX) into a single optical feed and are amplified using Marconi's field-proven Fiber-Optic Amplifier technology. The signal is split into incremental feeds, forwarded to a distribution optical amplifier for a final signal boost, and fed into the SWFX. The video signal is then distributed over the same fiber as the voice and data signals.

Marconi's Deep Fiber FTH solution optimizes the passive optical network infrastructure, allowing service providers to offer homeowners communication and entertainment services today over a very high-quality, future-proof, low-maintenance and unlimited-capacity medium.
