Avago ramps up production of QSFP+ active optical cable and transceiver products

NOVEMBER 16, 2009 -- The company says its QSFP+ 4x10-Gbps InfiniBand technology expands reach while lowering power and improving EMI over copper interconnect.

NOVEMBER 16, 2009 -- Avago Technologies, a supplier of analog interface components for communications, industrial, and consumer applications, will showcase its QSFP+ active optical cable (AOC) and transceiver products for short-range InfiniBand and Ethernet applications this week at Supercomputing '09. Avago's AFBR-79Q4xACyyZ is a high-performance integrated cable for short-range multilane data communication and interconnect applications. It integrates four data lanes in each direction with 40-Gbps aggregate bandwidth into a single module. Each lane can operate at 10 Gbps with lengths ranging from 1 to 100 m.

The AFBR-79Q4xACyyZ QSFP+ AOC assembly and AFBR-79Q4Z transceiver utilize multimode fiber at a wavelength of 850 nm. The electrical interface uses a 38-contact edge type connector. The four-channel pluggable AOC and transceiver incorporate Avago's integrated circuit and VCSEL technology to provide long life and reliability.

"As the bandwidth needs have increased, copper interconnects are becoming less and less attractive due to the bulk of the connectors, cables, electromagnetic interference (EMI) issues, weight management, and reduced distance capability. As a result, parallel optics is now a natural replacement for parallel copper interconnects," says Sami Nassar, senior director of marketing, Fiber Optic Product Division, Avago Technologies. "The QSFP+ active optical cable assembly and transceiver provide a hot-pluggable solution with data rates from 5 Gbps up to 10 Gbps per channel. Compared to other 10-Gbps serial solutions, these QSFP+ solutions help to improve port density by more than two times and reduce power consumption by more than 50% to allow systems companies to lower their overall cost per port."

Copper cabling is typically a bulky solution with a limited reach of 3 to 15 m at 10-Gbps/lane data rate. A fiber-optic QSFP+ technology provides a longer reach and a tighter bend radius.

Avago will be conducting live demonstrations of its latest QSFP+ active optical cable and transceiver products at SC'09 from Nov. 16-19 in its booth (#2386). The demonstrations will include a 120-Gbps 12x QDR InfiniBand link that will be streaming traffic from the SCInet network. The second demonstration will be an example of a real-time advanced remote desktop that will allow exhibitors to share simulations, live video, and presentations.

Key features include:

  • four independent transmitter channels and four independent receiver channels per module
  • high channel capacity: up to 40 Gbps per module, bidirectional operation
  • fully compliant to 10-Gbps QDR IB, backwards compatible to 5-Gbps DDR IB, and 2.5-Gbps SDR IB
  • operates up to 10 Gbps with 8b/10b compatible coded data
  • case temperature operation range: 0 to 70 degrees Celsius -- compliant to the InfiniBand Architecture Release 1.2.1 QDR specification, and to SFF-8436 specification for QSFP+ optical modules
  • compatible to the industry standard IN-8436i QSFP transceiver specification Rev. 1.0


Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
