The BPD1GA is an AC-coupled high-speed dual-balanced InGaAs photoreceiver. Due to its high transimpedance gain, its very low noise, and its bandwidthof 1 GHz, it is ideally suited for future ultrahigh speed swept-source OCT systems with depth scan line rates up to above 1 MHz.

The BPD1GA comes in a rugged aluminum case with two FC fiber receptables and a50 Ω coupled SMA output. It operates from a single 11-15 V DC supply.

OEM versions without a case are available upon request.

Features

  • Bandwidth: 300 kHz to 1 GHz (AC cutoff 30 kHz to 5 MHz on request)
  • High transimpedance gain: 3500 V/W (1550 nm)
  • Low noise: Typically -130 dBm/Hz noise level
    NEP 20 pW/sqrt(Hz) (at 1550 nm)
  • Wavelength range: 1000 nm to 1700 nm
  • 11-16 V single supply
  • Input: FC fiber receptables
  • Output: 50 Ω coupled SMA plug
  • Damage threshold: 10 mW
