NeoPhotonics giving demos enabled by new products for 100-400G telecom and datacenter networks

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) says that at the Optical Fiber Communication Conference & Exhibition (OFC 2016) in Anaheim, CA, USA (22-24 March) it is conducting demonstrations of 100G to 400G transmission, enabled by new products for 100-400G telecom and datacenter networks, including a CFP2-ACO Class 3 pluggable module, a 45Gbaud integrated coherent receiver (ICR) and a 56Gbaud electro-absorption modulated laser (EML).

First, the operation and optical signal-to-noise ratio (OSNR) performance of NeoPhotonics' ClearLight CFP2-ACO Class 3 pluggable coherent module is being illustrated in a loop-back DP-QPSK 100G configuration. The pluggable module incorporates the firm's ultra-narrow-linewidth power-efficient tunable laser and high-responsivity coherent receiver and is also suitable for 200G DP-16QAM operation.

Second, the new 45Gbaud micro coherent receiver will be used with the firm's ultra-narrow-linewidth tunable laser to show the bit-error rate (BER) and OSNR performance of a single-wavelength 400G datacenter interconnect link utilizing a 45Gbaud DP-32QAM configuration. This demonstration also includes NeoPhotonics' off-line digital signal processing (DSP) algorithms. This configuration can also be used for 200G transmission over long-haul reaches with 45Gbaud DP-8QAM, and 300G transmission over metro reaches with 45Gbaud DP-16QAM.

Finally, a single-wavelength 112Gbps link enabled by the new 56Gbaud EML with integrated driver in a PAM4 configuration is being shown for intra-datacenter connections of up to 2km. This configuration can also be utilized to make a four-wavelength 400G intra-datacenter transceiver module.

"The drive for higher-density optics has not reduced the requirements for high performance, particularly as transmission speeds move toward 400G, making it imperative to select the best technology for each function," says chairman & CEO Tim Jenks. "These demonstrations combine several elements of our advanced hybrid photonic integration technology, including our hybrid silica/InP ICR [integrated coherent receiver], our ultra-narrow-linewidth tunable laser, as well as our integrated high-speed EML and driver, and illustrate how high performance can be achieved by closely combining different technologies for different functions in a compact form factor," he adds.

Also at OFC (in booth 3301) NeoPhotonics is exhibiting its suite of standard and small-form-factor photonic integrated circuit (PIC)-based components for 100-400G coherent line-side applications, along with its 100G client-side and datacenter CFP2 and QSFP28 transceivers, its multi-cast switches for 'contentionless' reconfigurable optical add/drop multiplexers (ROADMs) and its next-generation transceivers for access.
