NeoPhotonics extends high-speed pluggable transceiver platform to 400G with CFP8 PAM4 development

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 announced its 400G transceiver development for network interconnections in data-center, cloud and other telecom applications.

"The drive for higher performance and higher density in optics is increasing as transmission speeds move toward 400G," says chairman & CEO Tim Jenks. "We are extending our high-speed product family in a manner which leverages both proven, high-performance and high-volume capabilities, while providing an efficient path to high density and higher speed," he adds.

NeoPhotonics' 400G PAM4 (4-level Pulse Amplitude Modulation) CFP8 form-factor module development leverages the firm's high-speed component technologies including:

  • a 28Gbaud high-performance EML (electro-absorption modulated laser);
  • high-speed opto-electronics packaging techniques; and
  • high-performance and low-loss multiplexers.

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

NeoPhotonics' high-speed module technologies from its QSFP28 and CFP2 dual-rate 100G LR4 products are leveraged in this new 400G CFP8 LR8/FR8 PAM4 development. This also leverages the firm's demonstrated 100G dual-lambda PAM4 transmission, introduced at the European Conference on Optical Communications (ECOC 2015) and complying with the 400GBASE-LR8 standard.

"A number of market factors are driving the need for smaller and faster 400G client-side transceivers, as the move to 400G cannot be reasonably achieved by using the same 100G modules," says Jenks. "Our 400G PAM4 CFP8 solution will fulfill key market needs by leveraging the superior link performance of our high-performance EML lasers, while reducing power consumption through integration of technology-leading CMOS PAM4 chipsets," he believes.

Also, at the Optical Fiber Communication Conference & Exhibition (OFC 2016) in Anaheim, CA, USA (22-24 March) NeoPhotonics is giving a live demonstration of its single-wavelength 112Gbps link enabled by the firm's new 56Gbaud EML with an integrated driver, which creates the path to delivering 100G and 400G transceivers in compact modules for data-center applications.
