Description
The SFP transceivers are high performance,cost effective modules supporting multi-rate of 155Mbps~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.The transceivers are compatible with SFP Multi-Source Agreement(MSA)and SFF-8472.For further information,please refer to SFP MSA.

Features
1．Operating data rate up to 1.25Gbps
2．1310nm laser and PIN photodetector for 20 km transmission with SMF
3．PIN photodetector for 100m transmission with SMF
4．Meet SFP MSA and SFF-8472 with LC receptacle
5．Metal Enclosure for Lower EMI
6．Comply with SFP MSA
7．Operation Temperature Range 0~70oC or-40~85oC Optional
8．Single+3.3V Power Supply
9．RoHS-6 Compliant

Applications
1．Gigabit Ethernet
2．Fiber Channel
3．WDM Application
4．Switch to Switch interface
5．Switch backplane applications
6．ATM
7．SONT/SDH/PDH
8．FDDI
9．Other optical transmission system
