1 Gbit/s Data Rates over Plastic Optical Fiber

The Japan Automotive Software Platform and Architecture JASPAR announced that KDPOF’s automotive optical gigabit Ethernet technology has successfully achieved their conformance tests. With the KD1053, KDPOF provides the first IEEE Std 802.3bv-compliant automotive 1000BASE-RHC PHY to deliver 1 Gbit/s data rates over plastic optical fiber (POF).

Hideki Goto, Chairman of JASPAR’s next generation high-speed network working group and group manager at Toyota stated: “KDPOF’s optical network solution greatly improves the speed of auto­motive networks and moves beyond obsolete, lagging networking proto­cols. Optical Ethernet techno­logy is ideal for future in-vehicle network infra­structure, since it provides a radiation-free harness, and thus meets prerequi­sites concer­ning electro­magnetic compati­bility (EMC). Higher speeds are achieved by wider use of the electro­magnetic spectrum, which forces OEMs to impose more and more stringent emissions limits on electronic components.”

Established in 2004, JASPAR’s mission is to identify the common issues to be faced in the future by the car electronics sector and initiate standardization in order to resolve these issues and encourage the resulting objectives across the entire automotive industry. Among over two hundred member companies are leading global carmakers and Tier1 suppliers such as Toyota, Honda, Mazda, Nissan, and Denso and so on.

Diverse Tier1 and Tier2 carmakers have carried out evaluation tests on KDPOF’s KD1053-based development boards in coordination with JASPAR. The wide-ranging test scopes included EMC emissions and immunity tests, plus extreme temperature testing with standard automotive POF and optical connectors compliant with current ISO 21111-4 CD. EMC included radiated and conducted emissions (voltage and current), bulk current injection (BCI) testing, radiated RF immunity, and portable handy transmitters immunity. In addition, electrostatic discharge (ESD) and transient pulses were performed. The KD1053 solution achieved all test standards by a significant margin.

“Our core objective at JASPAR is to generate an environment that enables those serving the Japanese automotive sector to cooperate and push automotive innovation further,” Goto added. “We are very pleased with the results achieved with this joint test project.” (Source: KDPOF)
