Lifetime Characteristics
In fiber optic transmission units that have been in use for some time, nearly all of the deterioration in characteristics is due to
a reduction in the fiber-output power (Pf). This is due to deterioration over time in the level of optical output of the LED used
as the light source.
The drop in the LED's optical output is thought to be caused by crystal flaws in the wafer or stress in the mold resin,
although the detailed causes are not clear.
The life of light-emitting devices is greatly affected by the operating conditions and operating environment as well as by the
lifespan characteristics of the particular device. Toshiba recommends that the user first check a device's lifetime
characteristics before selecting it and setting its operating conditions.
Regular maintenance, such as a check on the amount of light emitted is recommended.
Noise Resistance
To operate the fiber optic transmission units normally, they must be enclosed in a conductive case. The case for the units
is made of conductive material and should be grounded to provide shielding effectiveness. Also, the case potential must
be the same as for the SIGNAL-GND.
In some environments, simply shielding the case will not protect against noise. When using the fiber optic transmission
units, conduct live tests to check noise resistance.
Application Ranges
The fiber optic transmission units described in this product guide are intended for use in entertainment information
systems (e.g., car audio systems, navigation systems with no information that could affect the safety). These products
shall not be used in equipment whose malfunction or failure could have direct effects on the safety of the driver and/or
passengers.
Application Precautions
TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices
in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the
responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe
design for the entire system, and to avoid situations in which a malfunction or failure of such TOSHIBA products could
cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA
products are used within specified operating ranges as set forth in the most recent TOSHIBA products specifications.
Also, please keep in mind the precautions and conditions set forth in the "Handling Guide for Semiconductor Devices," or
"TOSHIBA Semiconductor Reliability Handbook" etc..
