17 November 2003 Austin, Texas Lightwave -The promise of fiber to the premises (FTTP) is gaining momentum with the arrival of standards-based broadband passive optical network (BPON) solutions. Motorola is addressing this growing market by introducing the first commercially available, industry-standard BPON optical network termination (ONT) solution to be offered by a major semiconductor supplier.
BPON is designed to enable more than a 10x increase in bandwidth over existing broadband technologies, such as xDSL and broadband cable. Telecommunication carriers can leverage the higher bandwidth of BPON technology (up to 622-Mbit/sec downstream) to increase their revenue streams by offering subscribers voice, video, and date services and can reduce deployment cost through point to multi-point architectures.
The MC92701 is a BPON layer termination device that fully complies with the ITU-T G.983 specification. Adherence to this industry standard enhances PON system interoperability, which in turn can make it easier to build and deploy FTTP networks. The MC92701 works in tandem with Motorola's PowerQUICC I and PowerQUICC II communication processors to provide a comprehensive system solution for ONT equipment used in FTTP systems. The MC92701 device has been designed to interoperate with PowerQUICC processors, which are widely used to handle communications and control functions in both optical line termination (OLT) and ONT systems.
"Optical network equipment manufacturers are looking for off-the-shelf PON solutions to reduce system-level cost, and we're addressing their needs by delivering BPON chipsets that enable cost-effective, standards-based solutions," said David Perkins, corporate vice president and general manager of Motorola's Networking and Computing Systems Group. "Motorola's BPON solutions expand the capabilities of PowerQUICC processors in ONT applications, enabling equipment manufacturers to accelerate the design, development and deployment of PON equipment."
"The PON market shows great potential with a large and growing installed base in Japan and proposed builds in the U.S. by leading RBOCs [regional Bell operating companies]," said Allan Armstrong, program director for Global Communications Semiconductors at RHK. "With the introduction of its BPON solution, Motorola is one of the few semiconductor suppliers focused on this opportunity. The pervasiveness of cost-effective, standards-based PON interface components will be a key success factor for mass-market deployment of PONs in the second half of this decade."
FTTx deployments and trials are on the upsurge worldwide. According to Japan's Ministry of Public Management, Home Affairs, Posts and Telecommunications, there are more than 600,000 FTTx subscribers in Japan, and more than 50,000 new subscribers are being added each month. FTTx deployment is also expected to increase in other areas of Asia and Europe in the coming years. According to RHK, carriers are beginning to invest in FTTx network infrastructure, and greenfield PON deployments are expected to accelerate in 2004 and 2005, with mass-market penetration beginning to ramp in late 2005.
The MC92701 is an ITU-T G.983 compliant BPON layer termination device that supports dynamic bandwidth assignment (DBA). DBA is an innovative capability for enhancing quality of service (QoS) in fiber-based broadband services and for enabling additional services that require bandwidth peaks beyond traditional fixed-bandwidth allocations.
The MC92701 also offers integrated clock/data recovery (CDR). Integration of CDR logic provides system developers with the flexibility to use lower cost 2R triplexer optical modules. The single largest bill of material cost in BPON equipment today is the triplexer module�the device that handles signal reshaping, regeneration, and retiming. The MC92701 leverages Motorola's broad ATM cell processing and clock data recovery expertise, integrating system timing and CDR on-chip to reduce bill of material and triplexer module costs.
Key features and functions of the MC92701 device include:
• 155/622-Mbit/sec downstream and 155-Mbit/sec upstream performance
• BPON layer termination
• DBA for enhanced QoS control and peak bandwidth allocation
• Integrated phase-locked loop and CDR
• ATM cell processing
• A seamless bus interface with the PowerQUICC architecture.
The PowerQUICC processor family is the industry's most widely used communications processor architecture, with nearly 83% market share, according to a May 2003 Gartner Dataquest report. PowerQUICC processors deliver integrated control and forwarding plane functionality for a wide range of customer premises equipment, access and edge applications, such as FTTx termination equipment, xDSL gateways, SOHO and enterprise routers, home networking equipment, wireless access points, wireless base stations, DSL access multiplexers, telecom switching, and T1/E1 termination equipment. Motorola has recently introduced PowerQUICC processor families that feature integrated security engines, providing a higher level of integration and encryption acceleration for secure networking equipment.
Motorola is currently sampling the MC92701 device. MC92701 production is scheduled for Q1 2004. For pricing information, please contact Motorola or your local Motorola sales representative.
