With the development of the ML9xx43 series, a temperature controller is no longer necessary for almost all mounting configurations because of its ability to function in temperature ranges of –20C-+95C, the widest range in the industry, while also contributing to the miniaturization and energy effiiency in optical communication devices.

Features of new products

1) Industry’s widest operating temperature range (-20C-+95C) contributes to miniaturiztion and high density mounting of optical communication devices
Previous 2.5 Gbps/100km semiconductor laser diodes were limited to operating temperature ranges of 0C-+85C3 because of a tradeoff between data transmission and optical output at high temperatures. With this semiconductor laser, we have increased the light conversion efficiency by optimizing the active layer in the area where light is emitted, and can now make reliable data transmission in temperatures from –20C-+95C without temperature control. This means the optical transmitter/receiver will no longer need a temperature controller, thus contributing to miniaturization, high-density mounting, and cost reduction.
2) Improvements in slope efficiency contribute to reduced power consumption by the optical transceiver.
To achieve the optical output necessary for data transmission at over 95C, it was necessary to improve the slope efficiency (a figure showing the efficiency of attained optical output). By optimizing the element construction it was possible to improve the slope efficiency by approximately 30% compared to previous models to 0.28W/A, thus reducing power consumption by the optical transceiver.

New CWDM Muxes

Omron is adding a 4 channel LX4, and an 8 channel ITU-T version alongside the existing standard 4 channel model P1X4A, claimed by the company to be the smallest passive CWDM Mux/Demux solutions in the world. In addition, new 5 and 9 channel devices will address the need for 4+1 and 8+1 configurations in applications requiring an “express� channel.

The P1X series is based on Omron’s highly successful Precision Arrayed and Combined Solutions (PACS) architecture. The use of a Micro Lens Array (MLA) and thin-film filters very precisely mounted in a glass block assembly, working in conjunction with an integral mirror, ensures low insertion loss, good channel uniformity and respectable cross talk performance. Using a proprietary small component count structure, the PIX series achieves an exceptionally ultra-compact form factor of L 14.5 x W 7.2 x H 4.7 mm.

New fibre-optic switches

Also on display will be Omron’s recently announced “Bâ€? version 1×2, 2×2 and 1×8 single mode optical switches. The P1S12-B, P1S22-B and P1S18-B switches offer reduced insertion loss and higher repeatability meeting the needs of demanding applications such as OXC, OADM, ring protect (restoration), signal monitoring, routing and testing in transmission and metro access networks.

The P1S12-B and P1S22-B models are compact (W 12.6 x L 31.6 x H 8.4 mm) featuring a space-saving design achieved by micro optic “VW� mirrored prisms.

The P1S18-B is the smallest of its type (W 16 x L 63.5 x H 8.5 mm) developed around an all-new purpose-made polarised magnetic linear actuator assembly, consisting of a specially developed sensor and latch mechanism coupled to a prism. This enables the switch to offer a true bi-directional function and accurately set and maintain a latched condition regardless of axis or inclination.

Having been the first company to introduce peelable ribbon to North America, Sumitomo Electric Lightwave has utilized its proprietary control process and Easy Split & Peel technology to develop the fully encapsulated 3×4-fiber ribbon matrix in which each set of 4 fibers is constructed into an easily splittable and peelable ribbon. Sumitomo’s exclusive technology makes its ribbon the only product in the industry designed to allow easy splitting of the ribbon fiber without the need of any tools. Because each 4-fiber subunit is completely encapsulated, the fiber coating is protected, thereby guarding against fiber damage, mechanical abrasions, and shearing of fibers during splitting. The ribbon design also allows the installer to quickly and easily peel back the ribbon, by hand, to expose the underlying fiber in preparation for connectorization or splicing.

The same technology has been used for Sumitomo’s existing 24 and 36 fiber ribbon portfolio in which 12 fibers can be segmented into 2 or 3 ribbon subunits respectively in preparation for cost effective mass fusion splicing. Sumitomo has also recently introduced its TomCatâ„¢ handheld 4-fiber mass splicer and FC-7 handheld 1-step fiber cleaver that complements the new 4-fiber ribbon for maximum efficiency and cost savings in FTTx applications.

“Sumitomo’s expertise and leadership in ribbon fiber control processes and manufacturing has led us to the development of an outstanding ribbon design that will help our customers deploy their FTTH/FTTP network more efficiently and cost effectively, ” comments Gary Bishop, director of product management at Sumitomo Electric Lightwave.

Sumitomo’s 3×4-fiber ribbon is compatible with existing 12-fiber ribbon, conventional mass fusion splicers, protective sleeves, splice enclosures, and ribbon connectors. The company expects to incorporate the 3×4-fiber ribbon design into its complete ribbon cable product line by early fourth quarter of this year.

“Passave has extensive experience with the gigabit broadband access market, based on its success in Asia with EPON devices,” said Danny Briere, CEO of TeleChoice, Inc. a telecommunications strategy consultancy that tracks the PON market closely. “You`ll see that experience map to their GPON products.”

Developing a low-cost, high performance GPON FTTH semiconductor is a significant technical challenge because it requires single-chip integration of gigabit and faster point-to-multipoint Passive Optical Network (PON) transmission topologies at a price-point suitable for consumer premise equipment such as access modems. Passave`s field-proven GigaPASS architecture delivers gigabit and higher transmission rates, provides wire speed protocol processing, and supports mixed-mode PON traffic.

“High-definition IPTV is the killer application driving demand for PON in North America,” said Michael Howard, principal analyst and co-founder of Infonetics Research. “Multi-gigabit service enables carriers to simultaneously deliver IPTV, data, and voice to their customers. Passave was the first silicon supplier to deliver gigabit-line-rate devices for Passive Optical Network (PON) equipment in volume, with its GigaPASS-based GE-PON devices.”

The GigaPASS FTTH Device Architecture

The GigaPASS architecture integrates multiple gigabit and faster packet-processing engines to deliver wire speed packet processing supporting IP and Ethernet protocol processing tasks. The GigaPASS architecture also incorporates the complex PON circuitry required for high-throughput passive optical networking and provides a programmable control processor with standard operating systems and extensible middleware platforms. This integrated system-on-chip architecture enables flexible performance characteristics and programmable feature sets.

Programmability is critical for service providers, who differentiate their services by incorporating special features and functions in hardware and firmware to support their service portfolios, and GigaPASS-based devices will help carriers to future-proof their access network equipment. Another feature, programmable DBA (dynamic bandwidth allocation), gives service providers the flexibility to scale bandwidth to the changing needs of customers dynamically in software and without the need for a “forklift upgrade.”

Key features of Passave`s new GigaPASS-based GPON devices under development include:

· GigaPASS architecture for wire speed performance at 2.5 gigabits/second downstream and 1.25 gigabits/second upstream

· An embedded, high-performance processor running Linux and VxWorks

· Forward error correction, which enables carriers to double the reach or number of customers that the network can support

· AES-128 encryption

· FSAN ITU-T G.984 standard compliance

Pricing and Delivery

The Passave PAS5211 OLT and PAS6211 ONT devices will be available in 2006. Pricing for the PAS5211 OLT starts at 300 and for the PAS6211 ONT pricing starts at 30 in 10,000-piece quantities.

"This development of the world’s first ring modulator in CMOS is a fantastic milestone for Luxtera and for our partners,” said Alex Dickinson, co-founder and CEO of Luxtera. "We have reached a point that was considered impossible—where optical interfaces can be faster and much smaller than their electrical counterparts while preserving the economy of silicon. At speeds of 10Gbit/s or higher, system designers must now focus on optical interconnect or risk falling behind the competition by limiting their interconnect choice to copper.”

Luxtera’s CMOS Photonics technology delivers the optical modulation required for practical high-speed optical fiber communication and the small dimensions required by future chip designers. Luxtera chips are built in the same CMOS process that Luxtera’s development partner, Freescale Semiconductor (NYSE: FSL, FSLB), uses for mass producing their leading-edge PowerPC™ based microprocessors. The integration of dense, high-speed photonics into regular silicon processes is a highly significant event for both the semiconductor and optics industries.

"This achievement came much earlier than expected, signaling how far ahead our technology is,” said Cary Gunn, co-founder and vice president of technology for Luxtera. “We are seeing a revolution in the making, with all the problems of electrical connectivity going away. We have a new method that will deliver better performances for decades."

"Microprocessor interfaces struggled for years to make small incremental steps in speed,” says Kevin Krewell, editor-in-chief of In-Stat’s Microprocessor Report. “Luxtera has an exciting technology that could eventually bring extremely high-bandwidth optical connectivity directly into the CPU, and do so in a cost- and silicon-efficient manner.”

“The ability to link components with huge bandwidth and low latency has always been a grand challenge for computer designers,” says Ashok Krishnamoorthy, distinguished engineer at Sun Microsystems. “With Luxtera’s CMOS Photonics technology, we are now starting to envision performance levels that were unimaginable a couple of years ago. There are some exciting possibilities for future systems design.”
