10 Gb/s High-Sensitivity High-Gain Limiting APD Optical Receiver
10 Gb/s High-Sensitivity High-Gain Limiting APD Optical Receiver
Description:
The DSC-R604-APD is a high-gain APD (avalanche photodiode) + Transimpedance + Limiting amplifier ideally suited for digital applications up to 11 Gb/s. The R604-APD offers a high optical sensitivity of -27.5dBm, an optical dynamic range > 27dB, differential transimpedance gain of 12,000 ohms, a decision threshold adjustment function and very low power dissipation of 200mW.
The R604-APD is available in both module and Lab Buddy instrument forms. Three module package styles are available: differential GPPO, single-ended K-connector, and a miniature surface mount package with CPW (coplanar waveguide) RF outputs. In Lab Buddy instrument form, an optional clock and data recovery (CDR) unit is available which provides a 3R (receive, reshape, retime) solution with a jitter tolerance of 0.6 UIp-p and conveniently interfaces with bit error rate (BER) test stations.
