(2) operating method the ld receptacle module shall change its forward v oltage requirement and optical output power accordi ng to temperature change. also, the ld receptacle module will require more operation current to maintain sam e output power as it degrades. in order to maintain output p ower, use of apc (automatic power control) is recom mended, whichusemonitorfeedbacktoadjusttheoperation current. confirm that electrical spike current generated by switching on and off does not exceed the maximum op erating current level specified herein above as absolute ma x rating. also, employ appropriate countermeasures to reduce chatteringand/orovershootinginthecircuit. (3) static electricity static electricity or electrical surges will reduce and degrade the reliability of the ld receptacle m odules. it is recommendedtouseawriststraporantielectrosta ticglovewhenhandlingtheproduct.
