Fiber coupler characteristics TOSLINKTM

TOSLINKTM is a product that uses plastic fiber/optical adapters to transmit digital signals.

Optical transmission module: electrical signals are converted into optical signals and transmitted to optical fibers.

Fiber/optical adapter: The path of the optical signal, optical connectors are required at both ends.

Optical receiving module: It receives optical signals from optical fibers and converts them into electrical signals.

TOSLINK 1300 series long-distance transmission optical module driving method

The TOSLINK 1300 series can drive LEDs with a simple circuit.

Optical modules for long-distance transmission (TOTX1350/TORX1350A)

(a) IF = 1.5 mA drive (when the transmission distance is less than or equal to 50m)

(b) IF=6 mA drive (with transmission distance equal to 50m to 100m)

Depending on the type of logic IC (IOH/IOL>6mA),

One inverter circuit can also be used to drive the LED of the optical transmission module.

 TOSLINK 1300 series low-power optical module driving method

B. Low-current optical modules (TOTX1350/TORX1355)

(a) IF = 4mA drive (when the transmission distance is less than or equal to 10m)

(b)  IF=1.5 mA drive (when the transmission distance is less than or equal to 5m)

 TOSLINK1300 series updates

TOSLINK 1300 series is a new series that can support longer distances and lower current consumption compared to TOSLINK 1900 series.

Package types are horizontal and vertical,

Provides chassis design flexibility.
