1000BASE-SX SFP 850nm 550m Transceiver


  • Data rate:1.25G
  • Distance:500m
  • Wavelength (nm):850
  • Source:VCSEL+PIN
  • DDM: YES
  • Media Type:MMF

The SFP transceivers are high performance, cost effective modules supporting 1.25Gbps data-rate and550mtransmission distance with MMF.

The transceiver consists of three sections: a VCSEL 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.
