Overview
The DK-SFP-1G series BIDI single mode transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps 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
¨ Dual data-rate of 1.25Gbps/1.063Gbps operation
¨ Compliant with SFP MSA and SFF-8472 with simplex LC or SC receptacle
¨ Digital Diagnostic Monitoring: Internal Calibration or External Calibration
¨ +3.3V single power supply
¨ Operating case temperature range of 0°C to +70°C (Commercial) or -40°C to +85°C (Industrial)
Applications
¨ Gigabit Ethernet
¨ Fiber Channel
¨ Switch to Switch interface
¨ Switched backplane applications
¨ Router/Server interface
¨ Other optical transmission systems
Absolute Maximum Ratings
These values represent the damage threshold of the module. Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.
