SMW Quad-Link System

Quad-Link Fiber Optic System
High-Performance 4x L-Band + 10 MHz IFL Over Single Fiber

The Quad-Link system transmits four L-band forward channels and a standard 10 MHz return channel over a single optical fiber. Using a direct-modulated 1550 nm laser and CWDM (Coarse Wavelength Division Multiplexing), it delivers a high-performance, fully analog Inter-Facility Link (IFL) over single-mode fiber—optimized for satellite and RF infrastructure applications.

Key Features

• High RF and Optical Performance

Engineered for superior signal integrity with excellent carrier-to-noise (C/N) ratio across extended distances.

• Fully Analog Design

No digital conversion, no software configuration—ready to use out of the box with no field setup required.

• Automatic or Fixed Gain Control

Integrated AGC (Automatic Gain Control) with an optional Fixed Gain mode, ideal for large antennas and beacon applications.

• 4x RF Channels via CWDM

Four L-band RF signals multiplexed over a single fiber using CWDM technology.

• Standard 10 MHz Return Channel

Provides an external reference path via the built-in 10 MHz diplexer.

• Up to 40 km Fiber Link Distance

Long-range capability depending on system link budget, while maintaining high signal fidelity.

• Interoperable Design

SMW Fiberoptics systems are compatible with many third-party indoor fiber link devices.

• Complimentary Link Budget Support

Free assistance for link budget planning available upon request.

Rugged Outdoor Design

• IP67 Fully Outdoor-Proof Enclosures

Designed for harsh environments—no separate outdoor enclosure needed.

• Compact and Durable

Both transmitter and receiver units are housed in rugged, lightweight aluminum enclosures for direct mounting on antenna or supporting structures.

• Wide Temperature Tolerance

Fully operational in extreme conditions: -40°C to +80°C.

• Q-ODC Fiber Connectors

Equipped with robust push-on, quick-connect Q-ODC connectors for reliable and easy fiber interfacing.

Versatility & Applications

• Bidirectional Flexibility

Four RF channels can be sent in any direction by simply swapping transmitter and receiver locations.

• Wide Frequency Range

Transmits any RF signal from 290–3000 MHz (optional 50–2750 MHz), covering Satcom, GPS, terrestrial TV, FM radio, and more.

• Built-In Features

Includes bias-tees and a diplexer for 10 MHz reference signal.

• Custom Configurations Available

Tailored solutions to meet specific installation or operational needs.

Typical Applications:

• Single fiber connection to one Quattro LNB-equipped Satcom antenna.

• Connection to four individual single- or multiband LNBs over one fiber.

• Single fiber uplink to multiple or multiband BUCs.
