Advanced Digital Processor (ADP) 400Gbps-FR4 TOSA
Advanced RF integrated circuits (DSP-less) uniquely designed to address power consumption, density and cost for 400Gbps high-speed optics in the intra data center applications, and compensates fiber dispersion for the inter-data centers, metro access and wireless 5G networks.
POWERFUL SOLUTION TO LEAP FROG EXISTING APPROACHES
Real-time proprietary FFE (feed forward equalization) pre-distortion circuitry increases the speed of optical components by 2.5-4 times. For example, 10GHz optics run at 25Gbps speed or 25GHz optics run at 100Gbps speed. This shortens the development cycle and needs of the fastest high speed optical components, in which each cycle usually takes around 10-15 years of time.
ADP signal processors utilize tap delay lines that are lower voltage and higher impedance thus very fewer transistors (i.e. hundreds of transistors). This compares to typical DSP using ADC/DAC to digitally parallel process signals at very fast data rate and much more transistors (i.e. billion transistors). Power consumption is reduced by two orders of magnitude and is critical in the next-gen data center applications.
Products are fully compatible and inter-operable with other vendors' devices. In another words, customers can enjoy the benefits of ADP's faster speed, savings in power consumption and no latency, without worries of any compatibility issue.
ADP processes signals at real-time thus no latency is introduced in the system. This compares to typical DSP causing delays from digitally process signals using large computations to correct system impairments. ADP plays an important role in premium applications such as high-speed trading.
All IC design utilizes existing proven fabrication processes. Manufacturing of TOSA devices require no change from existing 4x25G to 4x100G assembly processes. Ramp up to high volume production is therefore straight-forward.
