Description

ND-204 DC Optical Receiver – High-Sensitivity Receiver for Fiber-to-the-Home and CATV Networks

The ND-204 DC Optical Receiver is a compact, high-performance optical node designed for high-quality optical signal reception in broadband fiber optic networks. Ideal for FTTH (Fiber-to-the-Home), CATV (Cable Television), and other fiber-based network infrastructures, this device ensures efficient optical-to-RF signal conversion with outstanding stability and signal fidelity.

Designed for low-power operation using a DC power supply, the ND-204 is suitable for energy-conscious applications and offers reliability even in environments where AC power may be unavailable or impractical. With high sensitivity, automatic gain control, and dual RF outputs, it is a versatile solution for modern communication networks.


Key Features of ND-204 DC Optical Receiver

1. DC Powered Operation

One of the core advantages of the ND-204 is its low voltage DC power input, typically operating at 12V DC, making it energy-efficient and safe for small-scale or indoor installations. It can be powered via adapter or power inserter, allowing flexible deployment.

2. High Sensitivity Optical Reception

Equipped with an InGaAs photodiode, the ND-204 delivers superior optical reception performance. It can receive optical signals in the range of -9 dBm to +2 dBm, converting them accurately to RF signals with minimal distortion or loss.

3. Automatic Gain Control (AGC)

The receiver integrates AGC functionality, which automatically adjusts the RF output level based on variations in optical input power. This ensures consistent signal strength at the output, minimizing the need for manual tuning and improving the user experience.

4. Dual RF Output Ports

With two RF outputs, the ND-204 can serve multiple endpoints from a single optical input. This is particularly useful in small apartment buildings, offices, or homes with multiple TVs or networked devices requiring stable RF signal.

5. Compact and Durable Housing

The unit is housed in a compact metal enclosure, designed for efficient heat dissipation and resistance to environmental factors. Its rugged structure ensures long-term operation with minimal maintenance in both indoor and semi-outdoor environments.

6. LED Indicator Panel

The front panel features LED indicators for power and optical signal status, making it easy for technicians and users to monitor device health and identify issues quickly.


Applications of ND-204 DC Optical Receiver

1. Fiber to the Home (FTTH)

Perfectly suited for FTTH networks, the ND-204 acts as the endpoint receiver, converting incoming optical signals from the provider’s headend into RF signals for household use.

2. CATV Systems

In cable television applications, the ND-204 ensures clear, high-quality audio and video transmission with stable RF output. It supports analog and digital TV broadcasting with exceptional signal clarity.

3. Multi-Dwelling Units (MDUs)

The dual RF output feature allows the ND-204 to serve two different locations from a single node, making it an efficient choice for small housing societies or duplex apartments.

4. Mobile and Temporary Installations

Due to its DC-powered operation and compact design, the ND-204 is suitable for mobile broadcasting vans, temporary network setups, or emergency communication networks.
