1. SUN-POF008T Toslink Fiber Optic Transmitters
SUN-POF008T is assembled with plastic housing and opto-electric component packaged with
a 660nm AlGaAs LED and drive IC. It transforms the electrical signal to optical signal, which is
transmitted by 1mm diameter plastic optical fiber.
The component is operated at 3~5V and has high performance at low dissipation current,
steady light output and efficient coupling.
Features:
• High speed signal transmission (12Mbps NRZ Signal)
• TTL interface compatible
• 3~5V single power source
Applications:
• Digital audio equipment
• CD player
• DVD player |
