Key Features of CT0605E Optical Receiver Node

1. High Sensitivity Optical Reception

The CT0605E is equipped with a high-sensitivity photodiode that enables it to receive and convert low-level optical signals into high-quality RF output. It supports a wide optical input power range, typically from -9 dBm to +2 dBm, ensuring consistent performance even in networks with variable signal strength.

2. Excellent RF Output Quality

Designed for low distortion and high-fidelity signal transmission, the CT0605E delivers high-quality RF output suitable for analog and digital CATV signals. Its advanced circuit design minimizes signal degradation and ensures superior CNR (Carrier-to-Noise Ratio) and flatness across the entire bandwidth.

3. Wide Frequency Range

This receiver node supports a wide frequency range, often up to 860 MHz or more, making it compatible with modern broadband and high-definition cable TV services. Whether the signal is analog or digital, the CT0605E ensures clear transmission without interference or distortion.

4. Integrated AGC (Automatic Gain Control)

The built-in AGC functionality allows the CT0605E to automatically adjust its output level in response to varying input signal strength. This ensures stable output and protects downstream equipment from signal fluctuations, simplifying system management and reducing maintenance costs.

5. Compact and Durable Design

With its compact and rugged aluminum housing, the CT0605E is designed to withstand harsh environmental conditions. Its IP65-rated enclosure protects it from dust, moisture, and temperature variations, making it ideal for outdoor as well as indoor installations.

6. Low Power Consumption

The receiver operates with low power consumption, helping reduce energy costs in large-scale deployments. It can be powered via standard AC or DC inputs and is compatible with most existing power systems used in HFC and FTTx architectures.

7. Easy Installation and Maintenance

Equipped with clearly labeled ports, LED indicators for status monitoring, and standard optical and RF connectors, the CT0605E simplifies installation and reduces the time required for setup and troubleshooting. It’s designed for “plug and play” use, ideal for technicians working in the field.
