Mellanox Technologies, a supplier of end-to-end Ethernet and InfiniBand solutions, announced a new demonstration of 50 Gb/s silicon photonics optical modulators and detectors at the Optical Fiber Communication (OFC) conference. These 50 Gb/s devices are important components in 200 Gb/s and 400 Gb/s LinkX cables and transceivers, which are required to enable the next generation of InfiniBand and Ethernet speeds. These 50 Gb/s devices are a key component to developing end to end solutions for HDR 200 Gb/s InfiniBand and Ethernet infrastructure by the company’s 2020 goal.

“Silicon photonics is the enabling technology for 200Gb/s InfiniBand and Ethernet networks,” said Amir Prescher, executive vice president of business development and interconnect products at Mellanox. “The QSFP56 doubles the front panel density for next generation switches; enables 200G copper DACs and 50G breakout cables for adapters and inside-the-rack applications; and silicon photonics transceivers supports all data center reaches to 2km.”

The company plans to sell 50 Gb/s and 200 Gb/s Direct Attach Copper cables (DACs), as well as copper splitter cables. In addition, silicon photonics-based AOCs will be available for reaches up to 200m, and then silicon photonics transceivers will be available for longer reaches up to 2 km. All of these will be downward compatible with the previous generation of 40 and 100Gb/s networks.

In addition, Mellanox and Innolight Technology Corp announced availability of interoperable parallel single mode (PSM4) transceivers. This allows data centers to mix and match transceivers.

“Interoperability is an important consideration for Web 2.0, Cloud, and telecom customers,” said Osa Mok, chief marketing officer of InnoLight. “We are delighted to participate with Mellanox and Ixia to showcase the expanded capability of our wavelength agnostic transceivers.”
