DP-QPSK 40 / 100 Gbps Coherent Receiver Evaluation Kit, ICR-100-EVK
General Description
The ICR-100-EVK is an O/E evaluation kit designed to convert QPSK /PM-QPSK/ QAM (16QAM, 64QAM)optical data to differential electrical signals. It consists of coherent receiver (Fujitsu FIM24706/301), daughter adapter board, and mother power and control board. The ICR-100-EVK offers several user-adjustable characteristics such as RF gain, PD bias, and mode of operation, Auto Gain Control (AGC) or Manual Gain Control (MGC) and is ideally suited for a variety of applications. Additionally, the output voltage swing adjustment is available.
Key Features
- Four well-matched Linear Balanced PIN/TIA Photo-receivers.

Note 1: The ICR-100-EVK has two modes of operation, Manual Gain Control and AGC Automatic Gain Control. The mode of operation is set using the graphic user interface. Output swing can be controlled by AGC or MGC between the min. value and the max. value. This does not mean output swing can be controlled whole range from the min. value to the max. value.
Note 2: LO power should be properly set by user to obtain desired output swing. For responsivity from signal and LO port, linearly polarized optical input is aligned 45 degree to PBS and slow axis of PMF, respectively.
