400G OTN Transponder with AES

400G OTN Transponder with AES offers a dynamically reconfigurable mapping of 400GE or 4x100GE to 4xOTU4, 2xOTUC2 or 1xOTUC4 transponder/muxponder solution.


400G OTN Transponder with AES offers a dynamically reconfigurable mapping of 400GE or 4x100GE to 4xOTU4, 2xOTUC2, or 1xOTUC4 transponder/muxponder solution. It is a single SOC ASIC/FPGA-based solution. A standard set of software application programming interfaces (APIs) or a customizable software driver comes with all SOC solutions to allow ease of client software development. Customization in the SOC and Software API/driver is also available for our clients through our design services.

This product is our 400G SOC solution to transpond 4x100GE or 400GE client onto Optical Transport Network (OTN). In 4x100GE mode, each lane can be configured independently and clocking and timing are also independent. In 400GE/OTUC4 mode, the OmegaCORE processes the OTUC4 OH bytes in multiplexed fashion. In OTUC4 mode, the GFEC per 100G slice can be disabled or removed if external coherence module or high-gain FEC is used.

Line-Side Mode Support

  • 1x400G OTUC4 / ODUC4 (with or without GFEC)
  • 2x200G OTUC2 / ODUC2 (with or without GFEC)
  • 4x100G OTU4 / ODU4 (with or without GFEC)

Client-Side Mode Support

  • 1x400G Ethernet (400GE – IEEE 802.3bs-2017 )
  • 4x100G Ethernet (100GE – IEEE 802.3ba with 802.3bj FEC KR4/KP4)


The OTN core of OmegaCORE supports three levels of OH insertions and extractions : register programming, memory programming and external programming through a dedicated OH port. The gFEC function can be disabled (or removed to save area) and a custom high-gain FEC can be used. The OTN core supports full alarm and OH inserts and extracts as specified in ITU G.709 and ITU G.798.

Core Support

This core supports 100G, 200G, and 400G Ethernet clients. The core comes with optional Ethernet MAC/RS statistic and performance monitoring and AES-GCM encryption capability at the OPU layer.

Our SOC solution offers state-of-the-art technology to our clients as well as allows quick adaptability to changes in technology and standards. We always keep our SOC code base updated concurrent to the release date of the latest standard update. This allows for extremely short time-to-market with the latest technology available.


Proven Interoperability

All Alphawave Semi OmegaCORE’s have been tested on both Intel/Altera and Xilinx FPGA hardware. Alphawave Semi partners with leading test equipment vendors like Spirent and Viavi to prove interoperability.

The OmegaCORE family of IPs are designed for efficiency. Built-in data buffers are efficiently implemented to reduce overall delay through the data path. Variable delay (or jitter) is tightly managed to ensure 1588v2 time-stamp accuracy. Alphawave Semi can provide simulation models and routable RTL along with detailed interface documentation. Contact Alphawave Semi for more information.
