ClariPhy ships LightSpeed-II CL20010 chips to improve Internet bandwidth

Semiconductor vendor ClariPhy on Monday announced that it started shipments of its LightSpeed-II CL20010, a 28nm coherent system-on-a-chip (SoC), to improve Internet bandwidth for data centers.

The new chip delivers a multi-modulation architecture enabling Software Defined Networking (SDN) at the physical layer.

ClariPhy said the CL20010’s configurable bandwidth supports data rates from 40G to 200G per wavelength.

Andrew Schmitt, principal analyst, Carrier Transport Networking at Infonetics Research, said: “Flexible modulations to increase the capacity of coherent links over short interfaces are a crucial competitive advantage and I believe ClariPhy is the first component supplier to ship this.”

ClariPhy is trying to target the rapid growth in the Internet market. For instance, Cisco Visual Networking Index says global Internet traffic in 2018 will be equivalent to 64 times the volume of the entire global Internet in 2005, with metro traffic surpassing long-haul traffic by 2015.

“We see strong market demand for 200G coherent solutions for applications in optical transport networks, new data centers and cloud-based networks, where advanced performance, network flexibility, and a rich feature set are required,” said Richard Craig, president of Oclaro’s Integrated Photonics Business.


ClariPhy’s LightSpeed-II CL20010 28nm multimode SoC offers better integration, performance and SDN capabilities that allow the network to adapt in changes in traffic growth automatically.

The other advantage is that an increase of 170 percent in fiber capacity and a reduction of 50 percent in cost per bit versus today’s 100G coherent systems.

The new chip support standard 100G QPSK modulation, providing carriers the flexibility of using a single, software programmable line card for 200G and 400G transmission at distances exceeding 3500 kilometers.
