THine Electronics has announced it has developed the optical digital signal processor (DSP)-less chipset supporting pulse amplitude modulation 4-level (PAM4) 64Gbps for PCIe6.0 and will exhibit such demonstration on ECOC2024, one of Europe’s largest exhibition in the fibre optic communication technology industry, held from September 23rd to 25th, in Frankfurt, Germany.
THine’s optical chipset enables to save power consumption by 60% and to lower latency by 90%, by removing DSPs from optical communication systems in data centres. Many types of existing advanced optical communication with PCIe have bottle necks in large power consumption. For example, silicon-photonics types’ external modulation lasers consume large power, existing vertical cavity surface emitting laser (VCSEL) driver types’ DSPs as well. In addition, DSPs have certain delay issues for their digital signal processing.
To breakthrough these problems, THine has developed this new chipset that consists of VCSEL driver and trance impedance amplifier (TIA) for DSP-less active optical cable (AOC) solution with PCIe6.0 by THine’s state-of-art analog-based technology.
This industry-first optical PAM4 64Gbps chipset has achieved accurate signal recovery performance by evolving THine’s analog technology, removing DSPs from optical modules of data transmission and even from end-point ASICs.
“Wide penetration of generative AI derives tremendous increase of electrical power consumption in data centers and THine’s analog-based chipsets, removing optical DSPs from optical communication in data centres, can provide one of effective solutions by saving power by 60%,” said Yoichiro Minami, the president and COO of THine Electronics. “With this solution data centres can also lower latency in optical communication by 90% that results in improving response time for AI processing. In addition, THine also plans to develop an advanced optical chipset for PCIe7.0 consequently.”
Application:
- Super high-speed active optical cables
- Super high-speed on board optics (OBO) modules
