Vitesse Semiconductor announced a number of IC innovations spanning from the access to the core of next generation optical networks. Highlights include:
- Enhanced Forward Error Correction (eFEC) technology for implementation in ASICs or FPGAs. Vitesse’s proprietary Continuously Interleaved BCH (CI-BCH) eFEC code can be implemented in single FPGA form at 100G. The company calculates that compared to existing FEC solutions, its CI-BCH eFEC enables both 40G and 100G backbones to operate over 25-50% longer spans, respectively, with lower power, lower cost, and lower latency. Available for both FPGAs and ASICs, Vitesse’s CI-BCH code is offered at 7% and 20% FEC overhead for 40G and 100G implementations, respectively.
- A new 40G/100G Chipset for line cards, CXP, and CFP optical transceivers used in next-generation servers, routers, and OTN transport equipment. The new chipset supports packing Nx10G un-cooled DMLs of different wavelengths into a very compact area, critical for 40GBase-LR4, or ER4 or 10x10G PIC applications for 10km and 40km. It also extends optical links up to 120km without costly optical dispersion compensation, improving link margin in excess of 3dB. Additionally, the chipset meets and exceeds the 40 GbE and 100 GbE IEEE P802.3ba/D3.0 draft standard in areas such as optical stressed receiver sensitivity test and transmit jitter specifications. A reference design is also offered.
- An FEC-Feedback-Enabled Quad EDC/CDR Signal Conditioner for Ethernet, SONET/SDH, and Fibre Channel. The single-chip device provides four simplex channels of Electronic Dispersion Compensation (EDC) and integrated Clock and Data Recovery (CDR) functions. Supporting speeds of 8.5 to 11.3 Gbps, the VSC8247 makes possible low-cost, multi-lane implementations of metro and long-haul 40G links while supporting optional feedback from a forward error correction (FEC) device. It also offers unique features, such as Vitesse’s VScope embedded waveform viewing technology allowing remote diagnostics to observe and test 10G/40G/100G links while running traffic.
- Expansion of its FTTx Ecosystem — The newest members include FiberHome, Oplink and BroadLight. This Ecosystem is an industry forum for companies across the entire Passive Optical Network (PON) hardware spectrum to accelerate deployment of next-generation 10G-PON FTTx platforms.
