Altera Demonstrates First FPGAs to Interoperate with 100-Gbps Optical Module
[News Story] SAN JOSE, Calif., Feb. 21, 2012 /PRNewswire/ -- Enabling next-generation 100-Gbps networks, Altera Corporation (NASDAQ: ALTR) today announced it has successfully demonstrated interoperability with a 100-Gbps optical module using its 28-nm Stratix(Registered) V GT FPGAs. This is the first time an FPGA has demonstrated interoperability with a 100-Gbps optical module and illustrates Altera(Registered)'s commitment to helping system engineers and manufacturers develop higher density and lower power optical networks. Today's news follows Altera's announcement in September 2011-Gennum and Altera Demonstrate 4x25Gb/s ICs for Next-Generation 100Gb/s Networks. Combined, both solutions enhance the company's optical module offerings and pave the way for the industry's adoption of 28 Gbps.The demonstration will be showcased at the Optical Fiber Conference (OFC), being held at the Los Angeles Convention Center from March 6 to 8, 2012, in the Optical Internetworking Forum (OIF) multi-vendor booth 713. The demonstration tests 28-Gbps transmission technology over 2 km of single-mode (SM) fibre, utilizing Molex's zQSFP+ Interconnect System. The demonstration includes four channels of PRBS31 data generating within the Altera's Stratix V FPGA, which is tailored to support the most bandwidth-intensive communications systems. The data is then transmitted over a Gennum VSR host channel with 12 dB of insertion loss, through a Molex zQSFP+ connector to Gennum clock and data recovery (CDR) integrated circuits. The retimed outputs of the CDRs are transmitted to the Molex 1490-nm Optical Module, which loops the optical data back to its receiver through 2 km of SM fiber. In the receive direction, the data flows in the reverse order through the cascaded blocks ending at the FPGA. The error checkers within Altera's FPGA verify that the entire transmit and receive data path through the system is operating error free.With global Internet traffic expected to multiply dramatically over the coming years, significantly more bandwidth will be required, driving the need for large-scale network upgrades. Altera's Stratix V GT devices are designed to support 25- to 28-Gbps data streams for next-generation 100-Gbps pluggable fiber-optic modules, line cards and direct-attach copper cables using the 25G-QSFP+ and CFP2 form factors. They provide exceptional jitter performance with low power consumption.Featuring 28-Gbps integrated transceivers, Stratix V FPGAs deliver the highest system bandwidth at the lowest power consumption, under 200 mW per channel at 28 Gbps. Stratix V FPGAs support backplane, optical module and chip-to-chip applications through 28-Gbps transceivers, and up to 66 full-duplex 14.1-Gbps transceivers. The transceivers in Stratix V GT FPGAs provide the industry's highest system reliability with the lowest jitter.Altera will be showcasing its latest innovations in Optical Transport Network (OTN) intellectual property (IP) and 28-nm FPGA technology at OIF in booth 2825. The company will share information on key building blocks that enable system and equipment manufacturers to develop higher density and lower power optical networks for tomorrow's communication systems.
Crystalline materials enable high-speed electronic function in optical fibers
Scientists at the University of Southampton, in collaboration with Penn State University have, for the first time, embedded the high level of performance normally associated with chip-based semiconductors into an optical fibre, creating high-speed optoelectronic function.The potential applications of such optical fibres include improved telecommunications and other hybrid optical/electronic technologies. This transatlantic team will publish its findings in the journal Nature Photonics this month.The team has taken a novel approach to the problems traditionally associated with embedding this technology. Rather than merge a flat chip with a round optical fibre, they found a way to build a new kind of optical fibre with its own integrated electronic component, thereby bypassing the need to integrate fibre-optics onto a chip.To do this, they used high-pressure chemistry techniques to deposit semiconducting materials layer by layer directly into tiny holes in optical fibres.Dr Pier Sazio, Senior Research Fellow in the University of Southampton's Optoelectronics Research Centre (ORC), says: "The big breakthrough here is that we don't need the whole chip as part of the finished product. We have managed to build the junction - the active boundary where all the electronic action takes place - right into the fibre. Moreover, while conventional chip fabrication requires multimillion dollar clean room facilities, our process can be performed with simple equipment that costs much less."John Badding, Professor of Chemistry at Penn State, explains: "The integration of optical fibres and chips is difficult for many reasons. First, fibres are round and cylindrical, while chips are flat, so simply shaping the connection between the two is a challenge. Another challenge is the alignment of pieces that are so small. An optical fibre is 10 times smaller than the width of a human hair. On top of that, there are light-guiding pathways that are built onto chips that are even smaller than the fibres by as much as 100 times, so imagine just trying to line those two devices up. That feat is a big challenge for today's technology."Dr Anna Peacock, from the ORC who holds a Royal Academy of Engineering Research Fellowship, adds: "The incorporation of optoelectronic device functionality inside the optical fibre geometry is an important technological advance for future communication networks. In this sense, we can start to imagine a scenario where the data signal never has to leave the fibre for faster, cheaper, more efficient systems."The research also has many potential non-telecommunications applications. It represents a very different approach to fabricating semiconductor junctions that the team is investigating.ORC Postdoctoral Researcher, Dr Noel Healy concludes: "This demonstration of complex in-fibre optoelectronic engineering is exciting, as it has the potential to be a key enabling technology in the drive for faster, lower cost, and more energy efficient communication networks."
Insert or Remove Inline Network Devices with the Model 6296 Bypass Switch
ENP Newswire - 21 February 2012 Release date- 20022012 - Electro Standards Laboratories, Cranston, RI, has announced the Model 6296 single mode LC duplex fiber optic bypass switch. This switch is ideal for inserting or removing devices that are concatenated, linked together in a chain or series. The Model 6296 allows the user to quickly and easily establish the required connections to/from a device in order to include it in a network. Alternatively, the Model 6296 allows the user to quickly and easily break all connections to/from a device in order to exclude it from a network.In the Normal position the switch connects A to B and connects C to D allowing equipment connected to the B and C ports to be brought into the network. In the Bypass position, the switch connects A directly to D, isolating equipment connected to ports B and C from the network. Local control is via a front panel pushbutton. Front panel LED's display switch position and power status. When power is lost, the switch reverts to the Bypass position. When power is restored, the switch automatically switches to the Normal position. All fiber optic ports are LC Duplex Angle Polished Connectors, single mode, 9/125 micron, and support a wavelength range of 1310nm to 1610nm. The Model 6296 employs MEMS-based mirror/prism switch technology and supports Gigabit data rates. The switch comes complete with a UL approved wall mount power module, 120 VAC, 60 Hz, that supplies 12 VDC, 500mA to the unit. The power module has a 2-prong US non-polarized plug. An optional Wide Range Power Module, Catalog No. 517277, is also available. This wall mount power module, ideal for international applications, is CE, RoHS and UL listed and features 100VAC/240VAC, 50Hz/60Hz and an IEC 60320 C14 inlet. The dimensions of this sleek Rackmount Model 6296 fiber optic switch are 19.0' W x 1.75' H x 8' D (48.3 x 4.4 x 20.3 cm). The switch weighs approximately 4.5 lbs (2.0 Kg).
