Atextreme temperatures these values deviate basedon component tolerance. On average, the outputpower decreases as the temperature is increased bya factor 1dB / 5°C.MAXIMUM OPTICAL INPUT POWERPARAMETER FIBER TYPE100MB MULTI-MODEWavelength 1310 nmConnector LCTransmit power –20 dBmReceiver sensitivity –30 dBmPower budget 10 dBMaximum inputpower–14 dBmTypical distance 2 kmDuplex full/halfRedundancy yesINTERFACE TYPE TYPICAL DISTANCERS422 1200 mG.703 100 mEMITTER,FIBER TYPE TRANSMITPOWER RECEIVEDSENSITIVITY POWERBUDGET820 nm LED,Multimode –20 dBm –30 dBm 10 dB1300 nm LED,Multimode –21 dBm –30 dBm 9 dB1300 nm ELED,Singlemode –23 dBm –32 dBm 9 dB1300 nm Laser,Singlemode –1 dBm –30 dBm 29 dB1550 nm Laser,Singlemode+5 dBm –30 dBm 35 dBNOTENOTEEMITTER, FIBER TYPE MAX.
