OPTON WDM PASSIVE MINI NODE

OPTON WDM Passive Mini Node – High-Performance Wavelength Division Multiplexing for FTTH Networks

The OPTON WDM Passive Mini Node is a cutting-edge, compact optical receiver designed to support Wavelength Division Multiplexing (WDM) in FTTH (Fiber to the Home), FTTB (Fiber to the Building), and CATV (Cable TV) networks. This device plays a vital role in the last mile of fiber optic infrastructure, providing efficient signal demultiplexing and delivering high-quality video, voice, and data services to end-users with minimal power consumption and maximum reliability.

Built for network operators, ISPs, MSOs, and system integrators, the WDM Passive Mini Node ensures seamless signal separation and transmission using advanced WDM technology while offering a compact footprint for easy integration into space-constrained environments.

What is WDM Technology?

Wavelength Division Multiplexing (WDM) is a method of combining and transmitting multiple optical signals on a single fiber by using different wavelengths (or colors) of laser light. This technology significantly increases the capacity of existing fiber infrastructure without laying new cables.

The OPTON WDM Passive Mini Node utilizes this technology to effectively separate downstream CATV signals from data signals, making it an ideal component for integrated triple-play networks (voice, video, and data).

Compact, Lightweight, and Space-Saving Design

The Mini Node features a compact, low-profile enclosure, allowing it to be easily installed in wall-mounted boxes, building risers, residential junctions, or ONU/ONT cabinets. It is especially suitable for Multi-Dwelling Units (MDUs) and last-mile deployments where space efficiency is critical.

Its rugged aluminum casing offers excellent heat dissipation and electromagnetic shielding, ensuring stable performance in various environmental conditions.

Passive Design – No Power Needed

One of the key advantages of the OPTON WDM Passive Mini Node is its fully passive operation. It does not require any external power source, significantly reducing operational costs and improving system reliability. By eliminating the need for power at the receiving end, the device is highly energy-efficient and perfect for remote or hard-to-reach locations.

High-Quality Optical and RF Performance

The Mini Node is equipped with a high-sensitivity photodiode and RF circuit that delivers stable, distortion-free RF output. It ensures excellent Carrier-to-Noise Ratio (CNR) and low intermodulation, resulting in crystal-clear analog and digital TV transmission.

Typical optical input levels range from -8 dBm to 0 dBm, supporting a wide range of signal conditions without degradation. The WDM filter precisely separates the 1550nm CATV signal from the 1490nm/1310nm data signals, ensuring interference-free delivery of services.

Seamless Integration and Flexible Applications

Thanks to its plug-and-play configuration, the OPTON WDM Passive Mini Node can be integrated into new or existing GPON/EPON networks with minimal setup. It is compatible with most standard GPON ONUs, CATV headends, and fiber splitters.

This makes it ideal for a wide range of applications, including:

• FTTH triple-play service delivery
