NeoPhotonics samples PAM4-based 400G pluggable CFP8 transceiver module for links up to 10km

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 begun sampling its 400G CFP8 transceiver modules, designed for data-center interconnection and client-side telecom applications. The CFP8 represents the first step on the firm's 400G roadmap for data-center and client-side applications.

NeoPhotonics' 400G PAM4 (4-level pulse amplitude modulation) CFP8 module leverages the firm's high-speed component technologies, including its 28 Gbaud low-power electro-absorption modulated lasers (EMLs) as well as its high-speed PIN photodiodes. The CFP8 module relies on the high-volume, production-proven 28 Gbaud component platform used in the currently deployed NeoPhotonics' 100G LR4 modules and leverages its continuous EML technology improvement specifically focused on lowering power consumption while assuring superior high-speed performance. As part of this development, NeoPhotonics recently announced an EML with the driver integrated into the EML at the chip-on-carrier (CoC) level.

NeoPhotonics' 400G CFP8 transceiver is designed to be compliant with the IEEE 802.3bs 400GBASE- LR8/FR8 specifications for links up to 10km.

The new 400G CFP8 module "extends our high-speed product family in a manner that leverages both our proven high-performance and high-volume production capabilities, providing an efficient path to high density and higher speed," says chairman & CEO Tim Jenks. "Our 400G PAM4 CFP8 solution will fulfill imminent market needs by leveraging the superior link performance of our high-performance EML lasers, while reducing power consumption through integration with technology-leading CMOS PAM4 chipsets," he believes.
