low power ROSA for 100GBase CFP4/QSFP28-LR4 transceivers
at the OFC

HUBER+SUHNER Cube Optics AG will showcase its latest ultra-compact integrated multi-lambda 100 Gbps Receiver Optical Sub-Assembly (ROSA), compatible with CFP4 and QSPF28 form factors at the OFC/NFOEC 2015 in Los Angeles, booth 1109.

Together with Keysight Technologies Inc., Cube Optics is showing a live demo at OFC booth 1201, highlighting the performance of this novel technology. The ROSA yields superior performance in a robust and reliable design. With its miniature size of only 18 x 6.5 x 6 mm and typical power consumption of barely 330 mW, the ROSA sets a standard for the next-generation pluggable transceivers in datacenter and LAN applications.

The ROSA modules are currently available for customer sampling and volume production will start in Q3 2015.

The ROSA incorporates an optical de-multiplexer, integrated four PIN detectors and an array quad Trans-Impedance Amplifier (TIA). 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 28.3 Gbps. After de-multiplexing, opto-electronic conversion and amplification, it outputs four lanes of electrical data each at rates of up to 28.3 Gbps.

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 features typical OMA sensitivities of -11.5 dBm for a BER of 10e-12.

“100GbE is quickly being deployed to enable network backbones to deal with the increasing bandwidth demand while meeting expectations for uptime,” said John D’Ambrosia, Ethernet Alliance chairman of the Board of Directors, and IEEE 802.3bs Task Force chair.   “Continuing development of the underlying optical technologies, such as H+S Cube Optics AG’s multi-lambda 100G ROSA, provides the industry with an expanding array of tools to meet network needs, and enable the next generation of 100GbE optical modules.”



HUBER+SUHNER Cube Optics AG sells a family of ultra-compact optical components and modules tailored to the demands of the access network. Its innovative active/passive opti­cal packaging platforms enables Cube Optics to provide outside-plant Telcor­dia approved, bandwidth enhancing solutions at compelling price points.


This miniature packaging platform leverages advanced micro-injection molding techniques and enables network operators to realize low-cost, high performance architectures for both large and small network deployments and legacy infrastructure upgrades. Cube Optics’ products have been implemented in a wide variety of applications including local loop unbundling, HFC/MSO capa­city upgrades, FTTX roll-outs as well as in equipment for the test and measure­ment of access networks.
