100BASE-LX SFP 1310nm 20km Transceiver


  • Data rate:100M/155M
  • Distance:20km
  • Wavelength (nm):1310
  • Source:FP+PIN
  • DDM: YES
  • Media Type:SMF

The SFP transceivers are high performance, cost effective modules supporting 155Mbps data-rate and20kmtransmission 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.
