Precaution on Use (1) (2) (3) Maximum Rating The maximum ratings are the limit values which must not be exceeded when using the device. Any one of the rating must not be exceeded. If The maximum rating is exceeded, the characteristics may not be recovered. In some extreme cases, the device may be permanently damage. Life of Light Emitters When the optical module is used for over a long period, degeneration of characteristics is mostly due to lowering of the fiber output power (Pf). This is caused by the degradation of the optical output of the LEDs used as the light source. The cause of degradation of the optical output of the LEDs may be defects in wafer crystallization or mold resin stress. The detailed causes are, however, not clear. The life of light emitters is greatly influenced by operating conditions and usage environment as well as the life characteristics unique to the device. Thus, when selecting a light emitter and setting the operating conditions, Toshiba recommends that you check the life characteristics. Depending on the environment conditions, Toshiba recommends maintenance such as regular checks on the amount of optical output. Soldering Optical modules use semiconductor devices internally. However, in principle, optical modules are optical components. At soldering, take care that flux dose not contact the emitting surface or detecting surface. Also take care at flux removal 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 non-halogen (chlorine-free) 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. 1997-06-09 6/8TOSHIBA TOTX194 (4) (5) (6) (7) (8) (9) (10) Vibration and Shock This module is resin-molded construction with wire fixed by resin. This structure is relatively sound against vibration or shock, In actual equipment, there are some cases where vibration, shock, and stress is applied to soldered parts or connected parts, resultingin line cut. Attention must be paid to the design of the mechanism for applications which are subject to large amounts of vibration. Fixing Fiber Optical Transmitting Module Solder the fixed pin (pins5 and 6) of fiber optic transmitting module TOTX194 to the printed circuit board to fix the module to the board. Solvent When using solvent for flux removal, do not use a high acid or high alkali solvent. Be careful not to pour solvent in the optical connector ports. If solvent is inadvertently poured there, clean with cotton tips. Protective Cap When the fiber optic transmitting module TOTX194 is not in use, use the protective cap. Supply Voltage Use the supply voltage within the Typ. operating condition (Vcc =5 +0.25V). Make sure that supply voltage does not exceed the maximum rating value of 7V, even instantaneously. Input Voltage If avoltage exceeding the maximum rating value (Vcc +.0.5V) is applied to the transmitter input, the internal IC may degrade causing some damage. If excessive voltage due to surges may be added to the input, insert a protective circuit. Soldering Condition Solder at 260C or less within three seconds. 1997-06-09 7/8TOSHIBA TOTX194 (11) (12) Precaution on Waste When discarding devices and packing materials, follow procedures stipulated by local regulations in order to protect the environment against contamination. Compound semiconductors such as GaAs are used as LED materials for this module. When discarding waste or at final processing, attention must be paid to workers and the environment.
