Fujitsu Introduces World's First Dual Carrier LN Modulator for 400G Optical Networks
- Wideband, compact, Dual Carrier LN Modulator for next generation 400G optical networks -
Kawasaki, Japan, February 1, 2016 - Fujitsu Optical Components Limited (FOC) announced today that on February, 2016 it will be releasing the world’s first Dual Carrier (*1) LN (*2) Modulator supporting 200G DP-QPSK (*3) and 400G DP-xQAM (*4) modulation formats for beyond 100G optical networks. Twice the transmission capacity of conventional LN modulators is achieved by integrating two compact sized DP-QPSK Mach-Zehnder modulators into one package. This product will help facilitate compact, high performance, low power consumption optical network equipment for 200G/400G optical networks.
Internet services such as cloud computing have led to a rapid increase in the volume of communications traffic. The arrival of the IoT (Internet of Things) age will further accelerate the volume of communications traffic in the future. This has led to the spread of 100G optical networks and increased demand for next-generation beyond 100G optical networks The requirement for core and metro networks to handle larger capacity and longer distance on their links has resulted in the expansion of 100G optical networks using digital coherent transmission systems (*5). R&D activities related to the commercialization of next-generation beyond 100G optical networks has also gained significant momentum. On the transmission side of these coherent optical transceivers high performance LN modulators supporting both 200G DP-QPSK and 400G DP-xQAM modulation format are required.
FOC has successfully commercialized the world’s first Dual Carrier LN Modulator supporting 200G DP-QPSK and 400G DP-xQAM modulation formats for beyond 100G optical networks. This product integrates 2 DP-QPSK Mach-Zehnder modulators into 1 compact package to achieve twice the transmission capacity of conventional LN modulators. This product will help facilitate compact, high performance, low power consumption optical network equipment for 200G/400G optical networks.
Key Features
- Twice the transmission capacity of conventional LN modulators while maintaining a compact size
A new process technology which improves the modulation efficiency of the LN modulator chip, and a wideband G3PO RF interface instead of the GPPO RF interfaces used in conventional 100G DP-QPSK modulators keep the package compact while achieving doubled transmission capacity over standard LN modulators. - 200G DP-QPSK and 400G DP-xQAM modulation format support
The Dual Carrier LN Modulator integrates 2 DP-QPSK LN modulators onto 1 chip and 2 polarization beam couplers into 1 compact package to provide support for both 200G DP-QPSK and 400G DP-xQAM modulation formats.
FOC plans to display samples of this product at OFC 2016, which is scheduled to take place from March 22 to 24 in Anaheim, California, USA.

Glossary & Notes
(*1) The transmission method which bundles 2 carriers (wavelengths) modulated with different data.
(*2) Acronym for Lithium Niobate (LiNbO3).
(*3) Acronym for Dual-Polarization Quadrature Phase Shift Keying. A method of phase modulation for digital signals in which 2 bits of data are allocated to each of 4 modulated optical phases (0, 90, 180, 270°) for both P-polarized and S-polarized light.
(*4) Acronym for Dual Polarization-x Quadrature Amplitude Modulation. A method of phase modulation for digital signals where multiple bits of data are allocated to modulated optical amplitudes and modulated optical phases for both P-polarized and S-polarized light.
(*5) Converts the received optical signal to an electrical signal in the optical receiving section after combining the received optical signal with a local reference light. The waveform distortion that occurs in the optical transmission path is then compensated for by digital signal processing. This technique allows for significant reduction in system cost through the elimination of optical dispersion compensators and optical amplifiers for loss compensation.
