Overview
The OmegaCORE OTN 100G Transponder with AES is a multi-lane SOC solution to transpond 100GE or CBR100G client onto Optical Transport Networks (OTNs). Each lane can be configured independently. Each lane core supports mapping of CBR100G client and 100GE client. For 100GE client, the core can perform Constant Bit Rate (CBR) async mapping using GMP or packet mapping through GFP. With packet mapping, a bandwidth buffer is used for bandwidth management between the GFP mapper and the 100GE MAC.
Line Interface
- OTU4+G.709 GFEC
- OTL4.10 or OTL4.4 (with flexible deskew buffers)
Client Interface
- 100G Ethernet (IEEE 802.3ba + 802.3bj FEC)
- 100G CBR clients
Dynamically Reconfigurable
- Higher port density
- Better power efficiency
- Cost-effectiveness
Programmability
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.
Configurations
AES-GCM encryption and MAC/RS statistics and performance monitoring are optional add-on features to further enhance the power of the SOC.
Each lane is individually configurable through an easy to use Software Application Programming Interface (API)/customizable software driver.
Specifications
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.
Typical Applications
The following shows a few examples of how the transponder can be configured for different applications:
100GBASE-R <> CAUI/CAUI4 <> Ethernet Mac <> GFP-F <> OPU/ODU4 <> OTU4+GFEC <> OTL4.4/OTL4.10
100GBASE-R <> CAUI/CAUI4 PCS-R/MLD <> GMP <> OPU/ODU4 <> OTU4+GFEC <> OTL4.4/OTL4.10
100G CBR <> SFI-S <> GMP <> OPU/ODU4 <> OTU4+GFEC <> OTL4.4/OTL4.10
Each lane is independent and can be dynamically re-configured to perform a different function without affecting the other lanes in mission.
Our SOC solution can offer much higher lane (port) density per chip, typically 1-4 depending on ASIC/FPGA sizes. As a result of higher port density, better power efficiency and cost effectiveness can be obtained.
