SFP20SMLC 1.25G SFP SM LC 20KM MODULE DUAL FIBRE 1310NM

OVERVIEW The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 20km transmission distance with SMF. The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.   FEATURES Up to 1.25Gbps data links 1310nm FP laser and photo PIN detector for 20km transmission Compliant with SFP MSA and SFF-8472 with Duplex LC receptacle Digital Diagnostic Monitoring: Internal Calibration or External Calibration Compatible with SONET Compatible with RoHS 3.3V single power supply   APPLICATIONS SDH and SONET system Fiber Channel Switch to Switch interface Switched backplane applications Router/Server interface Other optical transmission systems OPTICAL AND ELECTRICAL CHARACTERISTICS   Parameter Symbol Min Typical Max Unit Notes Transmitter Centre Wavelength 1260 1310 1360 nm   Spectral Width(RMS)     4 nm   Average OutputPower Pout -9   -3 dBm 1 Extinction Ratio ER 9     dB   Optical Rise/Fall Time (20%~80%) tr/tf     0.26 ns   Data Input Swing Differential VIN 400   1800 mV 2 Input Differential Impedance ZIN 90 100 110 O   TXDisable Disable   2.0   Vcc V   Enable   0   0.8 V   TXFault Fault   2.0   Vcc V   Normal   0   0.8 V   Receiver Centre Wavelength 1260   1580 nm   Receiver Sensitivity       -23 dBm 3 Receiver Overload   -3     dBm 3 LOS De-Assert LOSD     -24 dBm   LOS Assert LOSA -35     dBm   LOS Hysteresis   1   4 dB   Data Output Swing Differential Vout 700   900 mV 4 LOS High 2.0   Vcc V   Low     0.8 V   Notes: 1.
