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 / BPSK / 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.
- Integrated Dual-Polarization 90 Degree Optical Hybrid.
- Two modes of operation: Automatic and Manual Gain Control.
- Independently adjustable differential gain, and RF output voltage swing.
- Bias voltage independently tunable for all photodiodes.
- Easy-to-use lab evaluation kit, with graphic user interface on Windows operating system.
- Single DC-12V power supply, and virtual USB control port.
