Toshiba launches low-current-consumption fiber-optic transmission modules for energy-sensitive applications

Tokyo-based Toshiba Corp has launched the latest addition to its TOSLINK fiber-optic transmission device line-up: fiber optic transmission modules that can send and receive signals from DC to 500kb/s with low current consumption up to a maximum distance of 10m when using APF (all plastic fiber).

A newly developed high-luminosity LED allows the new products to be driven at a lower current (1.5mA) than the existing products. Also, while existing products consume the same current regardless of whether the module is engaged in optical communication or not, the new products has a circuit configuration that drastically reduces current consumption (to 30μA) at times of no communication, suiting energy-sensitive applications. The power supply voltage is 5±0.25V.

The new products will be available in two package types: samples of the horizontal-type transmitting and receiving modules TOTX1353(F) and TORX1353(F) will be available by the end of March, with mass production in April; samples of the vertical-type transmitting and receiving modules TOTX1353(V,F) and TORX1353(V,F) will be available by the end of April, with mass production in May. The devices are compatible with JIS F05 optical connectors. Operating temperatures span -40°C to 85°C.

Applications include the transmission of control signals in, for example, wind and photovoltaic power generation systems, control devices, amusement machines, and battery controllers.
