100 Gigabit for the metro

ADVA Optical Networking has launched a 100 Gigabit transmission card designed for metro wavelength-division multiplexing (WDM) applications.

The firm claims this is an industry first: a direct-detection-based 100 Gigabit-per-second (Gbps) design using four, 28Gbps channels rather than current 10x10Gbps schemes.

OFC announcements and market trends

Avago Technologies, Finisar and Opnext spoke to Gazettabyte about market trends and their recent OFC/NFOEC announcements. 

More compact transceiver designs at 10, 40 and 100 Gigabit, advancements in reconfigurable optical add-drop multiplexer (ROADM) technology and parallel optical engine developments were all in evidence at this year’s OFC/NFOEC show held in Los Angeles in March.

“MSAs are designed by committee, and when you have a committee you throw away innovation and you throw away time-to-market”

Xilinx's 400 Gigabit Ethernet FPGA

Xilinx has detailed its latest 28nm CMOS Virtex-7 FPGA family that will support 400 Gigabit Ethernet on a single device. The Virtex-7HT completes the Virtex-7, joining the Virtex-7T and Virtex-7XT product families announced in June.

A single FPGA will support 400 Gigabit Ethernet duplex traffic. The FPGA can also support 4x100Gig MACs and 4x150Gbps Interlaken interfaces. Source: Xilinx

Why is it important?

Xilinx says its switch and router customers are more than doubling the traffic capacity of their platforms every three years. “They are looking for silicon that will support a doubling of capacity within the same form-factor and the same power budget,” says Giles Peckham, EMEA marketing director at Xilinx.
