5. Applicable Optical Fiber with Fiber Optic Connectors  
All Plastic Fiber (980μm core / 1000μm cladding), NA=0.5  
F05 type optical connector with Polished Surface.  
Plastic Cladding Silica Fiber (200μm / 230μm cladding),  
F05 type optical connector with Polished Surface.  
6. Precautions during use  
(1) Absolute maximum rating  
The absolute maximum ratings are the limit values which must not be exceeded during operation of device.  
None of these rating value must not be exceeded. If The absolute maximum rating value is exceeded, the  
characteristics of devices may never be recovered properly. In extreme cases, the device may be  
permanently damages.  
(2) Operating Range  
The operating range is the range of conditions necessary for the device to operate as specified in  
individual technical datasheets and databooks. Care must be exercised in the design of the equipment. If a  
device is used under conditions that do not exceed absolute maximum ratings but exceed the operating  
range, the specifications related to device operation and electrical characteristics may not be met, resulting  
in a decrease in reliability.  
If greater reliability is required, derate the device’s operating ranges for voltage, current, power and  
temperature before use.  
(3) Soldering  
Optical modules are comprised of internal semiconductor devices. However, in principle, optical modules  
are optical components. During soldering, ensure that flux dose not contact with the emitting surface or  
detecting surface. Also ensure that proper flux removal is conducted after soldering.  
Some optical modules come with protective cap. The protective cap is used to avoid malfunction when the  
optical module is not in use. Not that it is not dust or waterproof.  
As mentioned before, optical modules are optical component. Thus, in principle, soldering where there  
may be flux residue or flux removal after soldering is not recommended. Toshiba recommends that  
soldering be performed without the optical module mounted on the board. Then, after the board is cleaned,  
solder the optical module manually. Do not perform any further cleaning.  
If the optical module cannot be soldered manually, use nonhalogen (chlorinefree) flux and make sure,  
without cleaning, there is no residue such as chlorine. This is one of the ways to eliminate the effects of  
flux. In such a case, check the reliability.  
(4) Noise resistance  
Where the fiber optic receiving module case uses conductive resin, shield by connecting the reinforcing pin  
at a front end of the module to GND. When using this optical module, connect the pin to SIGNALGND.  
Where the fiber optic receiving module case has a resistance of several tens of ohms, take care that the  
case does not contact power line of other circuits.  
It is believed that the use of optical transfer devices improve the noise resistance. In principle, optical fiber  
is not affected by noise. However, especially receiving module which handle signals whose level is  
extremely small, are comparatively more susceptible to noise.  
TOSLINK improves noise resistance using a conductive case. However, the current of the signal output  
from the photodiode of the optic receiving module is extremely small. Thus, depending on the usage  
environment, shielding the case is not sufficient for noise resistance.  
When using TOSLINK, Toshiba recommends that you test using the actual device and check the noise  
resistance.  
Use a simple noise filter on the TOSLINK fiber optic receiving module power line. If the ripple in power  
supply used is high, further reinforce the filter.  
When locating the optical module in an area susceptible to radiated noise, increase shielding by covering  
the optical module and the power line filter using a metallic cover.
