NeoPhotonics Announces New Micro-ITLA With Up to 50 Percent Wider Tuning Range for Coherent Transmis

2019-09-23    Cfol


SAN JOSE, Calif., September 23, 2019 – NeoPhotonics Corporation (NYSE: NPTN), a leading designer and manufacturer of advanced hybrid photonic integrated circuit based modules and subsystems for bandwidth-intensive, high speed communications networks, today announced general availability (GA) of its Ultra-Narrow Linewidth Tunable C++ LASERTM Micro-ITLA, which has a tuning range of 6 THz, covering the full “Super C-band,” which is 50 percent more spectrum than a standard 80 channel, 50 GHz spaced laser. 

The C++ LaserTM supports full gridless tuning and accommodates any channel spacing, including 50, 75, 100, 125, and 150 GHz.  This new laser is based on the same proven and reliable high performance external cavity architecture as NeoPhotonics’ industry leading Micro-ITLA product line. The C++ LASERTM maintains comparable ultra-narrow linewidth, low phase noise and low power consumption, for which the current product is known, over a full 6 THz tuning range. 

New coherent transmission systems use higher baud rates (e.g., 64 or 96 Gbaud) to enable a long haul 200 Gbps or 400 Gbps transmission systems.  However, these higher baud rate systems require wider DWDM channel spacings, which result in a lower number of available channels within a fixed total bandwidth, and therefore the total fiber capacity is compromised.  Similarly, Data Center Interconnect and Metro Systems use these higher baud rates to achieve data rates of 400 Gbps and above per channel and encounter these same limitations.  

The C++ LASERTM can tune over 80 channels with a 75 GHz per channel spacing, for example, to fully capture the increase in fiber capacity generated by these newer modulation approaches.  Similarly the C++ LASERTM can tune over 120 channels on a standard 50 GHz grid spacing.  The availability of this new laser dovetails with recent developments in Fiber Amplifiers as well as NeoPhotonics C++ ICRTM Receivers and C++ CDMTM Modulators, completing the eco-system necessary to support transmission over the Super C-band.

"We are pleased to announce GA of our C++ LASER, which along with our C++ ICR and C++ CDM, enables an increase in fiber capacity of up to 50 percent," said Tim Jenks, Chairman and CEO of NeoPhotonics. "The ability of our C++ LASER to tune over the full 6 THz range of the “Super C-band” is a testament to the robustness of our External Cavity tunable laser technology, which maintains industry leading linewidth and phase noise along with high optical power output with low electrical power consumption over the entire range," concluded Mr. Jenks.
