Technical Data Sheet
Photolink- Fiber Optic Transmitter
PLT131/T5/8
Features
•
High speed signal transmission（ 8Mbps NRZ Signal）
•
TTL interface compatible
•
+3~+5V single power source
Descriptions
Photolink 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 and be 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 light coupling.
Applications
•
Digital audio equipment
•
CD player
•
DVD player
