HUBER+SUHNER Cube Optics set to showcase new PAM4 modulated ROSA for 200GBase-LR4 & 400GBase-FR8 transceivers at OFC 2018


Mainz, 1 March 2018 – HUBER+SUHNER Cube Optics AG will showcase its latest ultra-compact integrated multi-lambda 200 Gbps PAM4 Receiver Optical Sub-Assembly (ROSA), compatible with the 200G and 400GBase-FR8 standard at the OFC 2018 in San Diego, USA at booth 3239.

Cube Optics will present a live demo at its booth, highlighting the performance of this novel technology. The ROSA yields superior performance in a robust and reliable design. With its miniature size of only 15.5 x 6.5 x 5.8 mm and typical power consumption of barely 900 mW, the ROSA sets the standard for the next-generation of pluggable transceivers in data center and LAN applications.

The ROSA incorporates an optical de-multiplexer, integrated four PIN detectors and an array quad Trans-Impedance Amplifier (TIA) of extreme linearity supporting the PAM4 (Pulse-Amplitude-Modulation, 4 levels) modulation format. The optical signal it receives is four optically multiplexed signals over a single fiber utilizing the 1295.56, 1300.05, 1304.58, 1309.14 nm channels of the LAN WDM IEEE grid, each propagating at 28 GBdps. After de-multiplexing, opto-electronic conversion and amplification, it outputs four lanes of electrical data each at rates of up to 50 Gbps.

As such, the device constitutes the complete ROSA function for 200GBase-LR4 transceivers. By combining two ROSAs with different LAN WDM filter sub-sets, it empowers 400GBase-FR8 CFP8 transceivers, operating at 50Gbps on 8 lanes.

The core optical element, comprising a compact directly-reflecting multiplexing architecture, draws on Cube Optics? intellectual property and the company\-\-s fabrication expertise.

The ROSA modules are currently available for customer sampling and volume production will start in Q3 2018.
