40 Gb/s High-Gain Limiting PIN-TIA Optical Receiver

Description:

The DSC-R411 is a high-gain PIN + Transimpedance + Limiting amplifier ideally suited for digital applications up to 40 Gb/s. Due to its high conversion gain of 900 V/W and differential GPPO RF outputs, the R411 can be connected directly to commercial CDR / DEMUX modules. The R411 also offers a high optical overload of > +2 dBm, a very low power dissipation of 200 mW, and utilizes Discovery’s high-reliability InGaAs photodiode technology.

Salient Features:

• High differential conversion gain of 900 V/W
  
• High Responsivity at 1310nm, 1550nm & L-band
  
• Sensitivity of -10.5 dBm at a BER of 10^-12
  
• Overload of +4 dBm at a BER of 10^-12
  
• Differential AC-coupled GPPO-style RF outputs
  
• Very low power dissipation of 200 mW
  
• Low optical PDL @ 1550nm (typically 0.05dB)
  
• Meets GR-468 reliability standard

Applications:

• 40Gb/s SONET/SDH OC-768/STM-256 short reach
• 100 Gigabit Ethernet (100GE)
• Digital applications up to 40 Gb/s baud rate
• Analog & RF photonics applications requiring low noise and high conversion gain
• Military communications

Available Models:

• DSC-R411 - 40 Gb/s High-Gain Limiting PIN-TIA Optical Receiver
