PMC-Sierra Releases Pluggable GPON ONT Design

PMC-Sierra introduced a pluggable GPON Optical Network Terminal (ONT) reference design that can connect any Customer Premises Equipment (CPE) equipped with a standard Small Form-Factor Pluggable (SFP) port to a high-speed Passive Optical Network.

The low-power, plug-and-play ONT allows carriers and system vendors to upgrade existing service-oriented home and small/medium business equipment, including gateways, routers, and integrated access devices, to full GPON functionality without hardware or software redesign.

PMC-Sierra's pluggable ONT, which is based on its GPON SoC for mini-ONT applications, is powered by standard interfaces in the host device and does not require a dedicated power supply. It integrates an optical transceiver, an innovative host interface, and a complete OMCI stack that is interoperable with all major OLT systems on the market. It can be connected to any SFP receptacle and does not require any software or hardware modifications to the host system.

  • Year-over-year (1Q09 vs. 1Q10), the overall market is up 14%

  • The North American carrier router and switch market actually gained a bit in 1Q10, with manufacturer revenue up 1.5%, on the heels of an 18% gain in 4Q09

  • Compared to this time last year, the service provider switch and router market in North America is up 29%

  • Carrier Ethernet switch revenue was up 8% in 1Q10 from 4Q09, and is up 22% year-over-year (from 1Q09)

The report provides worldwide and regional market share, market size, forecasts through 2014, and analysis for IP core routers, IP edge routers, carrier Ethernet switches (CES), and multiservice ATM switches. The report also tracks IP edge routers and CES by application (multiservice edge, BRAS, Ethernet access transport, and Ethernet services edge), as well as port count and port revenue detail for Ethernet ports (10M/100M, 1G, 10G, 40G, 100G), ATM/frame relay/PPP ports, POS/ATM/WDM ports, and other ports (FDDI, serial, analog, etc.).

TeliaSonera Carries 127 Gbps Single Wavelength over 1,700km

TeliaSonera, in partnership with Opnext, demonstrated a single wavelength, real-time coherent 127G PM-QPSK (Polarization Multiplexed Quadrature Phase Shift Keying) modem running over a 1,700km span.

The trial conducted over a long haul link with 10 Gbps and 40 Gbps mixed traffic ran from Uppsala, Sweden to Olofström, Sweden and back for a total distance of 1700km and represents the longest un-regenerated real-time test to date. The TeliaSonera trial represents the first real-time, single wavelength 100G field trial in Europe.

Opnext noted that the transmission channel did not require optimization to implement the 100 Gbps technology, which further demonstrates the ease-of-use of coherent technology.

Currently, 10 Gbps and most 40 Gbps optical systems using direct detection require optimization and intervention by an optical network engineer to balance all of the optical impairments on an installed optical fiber. Opnext plug and play technology allows carriers to upgrade their existing line systems to 100 Gbps without requiring any change to their existing networks. In addition, new systems using Opnext technology can eliminate the need for external dispersion compensation, which reduces cost, minimizes IP latency and allows for deployment over older installed fiber.

"TeliaSonera has one of the largest and fastest growing IP backbones in Europe, and this trial demonstrates our focus on maintaining a state of the art network that is ready to use next-generation technologies, such as coherent 100 Gbps, from vendors like Opnext," said Staffan Göjeryd, Head of Broadband Development, TeliaSonera.

Quantenna's 4x4 MIMO Wi-Fi Powers In-Home Video Distribution

Quantenna Communications introduced its third-generation Full-11n 4x4 Multiple Input Multiple Output (MIMO) chipset, enabling whole-home video distribution of multiple HD streams using 802.11n Wi-Fi.

Quantenna's newest 802.11n Wi-Fi chipset breaks ground in several ways. First, the design has been optimized for volume production and the company estimates it is approaching the 3x3 MIMO price range. Device size has been cut in half and power consumption by one-third as compared to previous solutions. It incorporated features that simplify transceiver certification in the U.S., Europe and Asia. Error vector magnitude (EVM) and phase-noise performance have both been enhanced to boost range and reliability, and the chipset's receiver linearity significantly reduces interference. Quantenna said its solution can reliable deliver multiple HD video streams (100+ Mbps) over distances of 100 feet or more.

Quantenna's third-generation chipset incorporates all specifications in the IEEE802.11n standard including 4x4 Multiple Input Multiple Output (MIMO). It also incorporates extensions to the IEEE802.11n standard including dynamic digital beamforming, and wireless channel monitoring and optimizing. Furthermore, Quantenna has increased channel bandwidth to 80MHz. This will be useful because the IEEE is working on a new 802.11ac specification that promises speeds of up to 1.2 Gbps. Quantenna will leverage these capabilities.

David French, Quantenna's CEO, said that while other Wi-Fi silicon companies have focused on Wi-Fi designs for mobile handsets, his company has focused on the problem of in-home video delivery. Quantenna believes it is 12 months ahead of other companies in developing 4x4 MIMO silicon. In addition, Quantenna's beamforming technology and dynamic channel characterization enable high performance video bridging between home gateways and set-top boxes, TVs and other consumer electronics.
