De scrip tion
The OPF14XX series fiber optic
transmitters contain a high speed 840
nm GaAlAs LED. This LED in
conjunction with the package lensing is
designed to efficiently couple light into
optical fibers ranging in size from
50/125 µm up to 200 µm PCS. These
devices were designed to work
together with the Optek OPF24XX
series receivers to make-up a complete
high speed fiber optic link.
The high coupling efficiency of the LED
and lensing allows the devices to be
used at low current drive levels thus
decreasing the power consumption and
increasing system reliability. The
consistency of coupling varies by less
than 5 dB from part to part which
reduces the dynamic range
requirements of the receiver.
The high power (-16.5 dBm into 50/125
µm) OPF1414 was designed for small
fiber applications or where there are
large fixed losses such as in systems
that contain star couplers or in line
connectors. The OPF1412 (-11.5 dBm
optical power) is ideal for 100/140 µm
fiber applications.
