SFP05MMLC 1.25G SFP MM LC 550M MODULE DUAL FIBRE 850NM

OVERVIEW The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 550m transmission distance with MMF. The transceiver consists of three sections: a VCSEL lasertransmitter, 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 850nm VCSEL laser and PIN photodetector Compliant with SFP MSA and SFF-8472 with Duplex LC receptacle Digital Diagnostic Monitoring: Internal Calibration or External Calibration 500m transmission with 50/125µm MMF 300m transmission with 62.5/125µm MMF Compatible with RoHS 3.3V single power supply Operating case temperature: 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 830 850 860 nm   SpectralWidth (RMS)     0.85 nm   Average Output Power Pout -9.5   -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   TX Disable Disable   2.0   Vcc V   Enable   0   0.8 V   TX Fault Fault   2.0   Vcc V   Normal   0   0.8 V   Receiver Centre Wavelength 770   860 nm   ReceiverSensitivity       -18 dBm 3 ReceiverOverload   -3     dBm 3 LOS De-Assert LOSD     -20 dBm   LOS Assert LOSA -30     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.
