Description:
The OPF1412 and OPF1414 series fiber optic transmitters contain a high speed 840 nm GaAIAs LED. This LED
in conjunction with the package lensing is designed to efficiently couple light into multimode optical fibers ranging
in size from 50/125 µm up to 200/230 µm. 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 (-16.0 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 (-12.0 dBm optical power) is ideal for 100/140 µm fiber applications.
For custom electrical and optical requirements contact your local representative or OPTEK for more information.
