Toshiba Corp. said Thursday it has developed new fiber-optic receivers and transmitters for an automotive local area network.

The devices can operate at temperatures ranging from minus 40 to 85 degrees and deliver data at a speed of 125 megabits per second -- more than three times faster than current automotive LAN fiber-optic transmitters and receivers for automotive LANs, Toshiba said.

The development will open the way to LAN systems supporting advanced, high-speed entertainment systems in automobiles, the electronics maker said.

The new devices will be available in sample quantities in April, and mass production is expected to start in October at a monthly volume of 500,000 pairs, the company said.
