NeoPhotonics samples ClearLight CFP-DCO pluggable coherent transceiver module in launching platform for single-wavelength 100 and 200Gb/s transmission

NeoPhotonics Corp of San Jose, CA, USA (a vertically integrated designer and manufacturer of hybrid photonic integrated optoelectronic modules and subsystems for high-speed communications networks) has started sampling its coherent CFP-DCO module as part of its ClearLight Coherent Module platform introduction. The ClearLight DCO platform uses the latest advances in 16nm digital signal processors (DSPs) and is capable of achieving single-wavelength 100 and 200Gb/s transmission over datacenter interconnect (DCI) through long-haul transmission distances.

The ClearLight CFP-DCO platform is based on optical components with performance capabilities that have already been proven in high-volume production. These include a high-power tunable laser with what is claimed to be the narrowest linewidth and the lowest power consumption in the industry, a low-insertion-loss modulator capable of higher-order modulation, a high-responsivity receiver and a low-power-consumption DSP. These features enable the ClearLight CFP-DCO to deliver performance both high optical performance and low electrical power consumption, says NeoPhotonics, which adds that the 100G CFP-DCO provides a significantly higher transmitter optical signal-to-noise ratio (OSNR) by eliminating a booster erbium-doped fiber amplifier (EDFA) to achieve the necessary output optical power level. This high-transmitter OSNR can enable longer transmission distances and colorless, directionless, contentionless (CDC) reconfigurable optical add/drop multiplexer (ROADM) operation.

The first-release 100Gbps version uses a standard 100GE or OTU-4 interface that can plug directly into existing 100G CFP client-side slots to extend the range and capacity for metro and DCI applications. The module incorporates standard hard-decision staircase forward error correction (FEC) for interoperability, as well 16-QAM (quadrature amplitude modulation) as proprietary soft-decision FEC for high-performance applications. A 200Gbps version is based on the same platform and utilizes the same high-volume, proven coherent optical components.

"Our new ClearLight CFP-DCO 100G pluggable coherent transponder represents a powerful new platform product for NeoPhotonics," says chairman & CEO Tim Jenks. "This exciting new product is made possible by our Advanced Hybrid Photonic Integration technology, coupled with the latest advances in 16nm Coherent DSPs, and provides our customers with a flexible, high-performance pluggable coherent module for their high-speed networks," he adds.
