(2) operating range the operating range is the range of c onditions necessary for the device to operate as specified in individual technical datasheets and databooks. care must be exerci sed 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 electr ical 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 semiconducto r 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 comp onent. 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 boar d. 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 elim inate the effects of flux. in such a case, check the reliability. (4) noise resistance where the fiber optic receiving module case uses conduc tive 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 signal ? gnd. where the fiber optic receiving module case has a resist ance 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 im prove 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 comparativel y 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 te st 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 lin e filter using a metallic cover.
torx1950(f) 2014-05-20 4 (5) 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, resulting in li ne cut. attention must be pa id to the design of the mechanism for applications which are subj ect to large amounts of vibration. (6) fixing fiber optical receiving module solder the fixed pin (pins 5 and 6) of fiber optic rece iving module torx1950(f) to the printed circuit board to fix the module to the board. (7) shielding and wiring pattern of fiber optic receiving modules to shield, connect the fixed pins (pins 5 and 6) of fi ber optic transceiving module torx1950(f) to the gnd. where the fiber optic receiving module uses conductive resin, be careful t hat the case does not touch wiring (including land). to improve noise resistance, shield the optical modu le and the power line filter using a metallic cover. (8) 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. (9) protective cap when the fiber optic receiving module torx1950(f) is not in use, use the protective cap. (10) supply voltage use the supply voltage within the operating ranges (v cc = 5 0.25 v). make sure that supply voltage does not exceed the absolute maximum rating value of 6 v, even instantaneously. (11) output when the receiver output is at low le vel and connected to the power suppl y, or when the output is at high level and connected to gnd, the internal ic may be destroyed. (12) soldering condition solder at 260c or less within ten seconds. (13) incidence of a photo flash if strong light such as a photo flash is incident on an optica l module, a transmission error may occur. be careful to avoi d such situations. (14) precaution on waste when discarding devices and packing materials, follow procedures stipulated by local regulations in order to protect the environment against contamination.
