SUMMARY
This report summarizes the qualification tests
performed on the above Firecomms family of
RedLink® fiber optic transmitters and receivers.
RedLink® transmitters operate at 650 nm
wavelengths. Data rates for the transmitters range
from DC up to a maximum of 50 MBd. The 650 nm
transmitters contain a GaAs/AlGaInP Resonant
Cavity LED (RCLED).
RedLink® receivers operate across the visible
wavelength range. Data rates for the receivers
range from DC up to a maximum of 50 MBd. The
RedLink® receivers contain a monolithic IC with
integrated photodiode, transimpedance and
limiting amplifier functionality.
Listed in Table 1 are the part numbers to which this
document refers. For custom or specific part
numbers, customers should contact Firecomms
directly. The data collated in the qualification
process is also used to determine the predicted
lifetime values for the individual components.
TESTING
Firecomms RedLink® products are designed to
operate in harsh industrial environments where
products are exposed to elevated electromagnetic
interference, extended temperatures and severe
mechanical and environmental stress. To
demonstrate the ruggedness of the products while
also ensuring reliable performance over extended
lifetimes, the RedLink® products are subjected to
the testing program as detailed in Table 2.
The testing program was conducted in accordance
with internationally recognized standards to ensure
reliable product performance in the applicable
market sector.
Where possible all tests were conducted in-house or
alternatively at external accredited test facilities.
RESULTS
Summarized in Table 2 are details of the
qualification tests, stress conditions, relevant
standards, batch sizes and results. Also presented
are results of the high temperature operating life-
time (HTOL) testing used to provide the estimate of
the failures in time (FIT) and mean time to failure
(MTTF). In addition, accelerated life-time tests have
been performed to predict wear out of the
transmitter product.
CONCLUSION
The test results show the products have successfully
passed qualification for product release.
