HIGH RADIANCE LIGHT EMITTING DIODESME7XX2 SERIESFOR OPTICAL COMMUNICATIONTYPENAMEME7022,ME7032DESCRIPTIONME7XX2 are InGaAsP /lnP double heterostructurelight emitting diodes (LED) emitting light beamaround 1310nm.A spherical micro - lens is mounted on the lightemitting area to provide a highly optical couplingefficiency from LED to fiber.ME7XX2 provides a high radiance, narrow beamangle characteristic. Providing ring grooves from theP - side area to the junction to form the mesashapedlight emitting area, thus reducing theparasitic capacitance and realizing a high speedresponse. ME7022 and ME7032 have high reliabilityand long operating life. and are suitable for suchshort-distance communication systems as LAN anddata links.FEATURES• High cut-off frequency, typically 150MHz• High coupling power, typically - 17dBm• Pulse rise and fall times: typical 3ns and 4nsAPPLICATIONFiber - optic communication systems, local areanetworks, CATV trunks, industrial control, data linkABSOLUTE MAXIMUM RATINGSSymbol Parameter Conditions Ratings UnitIF Forward current - 120 mAVR Reverse voltage - 2.0 VTc Case temperature - -30-+ 80 °CTstg Storage temperature - - 40-+ 100 °CELECTRICAL/OPTICAL CHARACTERISTICS (Tc = 25°C)LimitsSymbol Parameter Test conditions ME7022 ME7032Min.
