Fujitsu Optical Components unveils dual-carrier 400-Gbps ICR, modulator

Feb. 4, 2016
Fujitsu Optical Components Ltd. (FOC) has introduced a pair of devices to support 400-Gbps transmission. The products include what the company asserts is the first dual carrier integrated coherent receiver and a dual carrier lithium niobate modulator to support both 200-Gbps DP-QPSK and 400-Gbps DP-xQAM.

Fujitsu Optical Components Ltd. (FOC) has introduced a pair of devices to support 400-Gbps transmission. The products include what the company asserts is the first dual carrier integrated coherent receiver and a dual carrier lithium niobate modulator to support both 200-Gbps DP-QPSK and 400-Gbps DP-xQAM.

The ICR module actually features a pair of compact ICRs. The design leverages planar lightwave circuit and micro-assembly technologies to integrate and mount 90° hybrids, balanced receivers, polarizing beam splitters, and variable optical attenuators (VOAs). This product will help facilitate compact, high performance, low power consumption optical network equipment for 200G/400G fiber-optic networks. It will be released this month.

The modulator unit also comprises a pair of DP-QPSK Mach-Zehnder modulators in a single package. The compact size derives from a new process technology that improves the modulator chip's efficiency as well as a wideband G3PO RF interface instead of the GPPO RF interfaces used in conventional 100G DP-QPSK modulators, FOC says. In addition to integrating a pair of DP-QPSK lithium niobate modulators onto one chip, FOC also has integrated two polarization beam couplers into the modulator package.

Both products will be on display at OFC in Anaheim this March.
