Description

RF Fiber Break System for High Security – 45-1000 MHz

Uni-Directional RF Fiber Break

PN: F-RF-BR includes:

  • 19" Rackmountable RF Fiber Optic Transmitter – Converts electrical RF signals into a modulated light signal for secure fiber transport.
  • Portable RF Fiber Optic Receiver – Converts the modulated light signal back into an electrical RF signal for distribution.
  • SC/APC Fiber Optic Jumpers – Used to connect the TX and RX for seamless signal transmission.

The F-RF-BR Fiber Break is an advanced RF isolation solution designed for high-security applications, ensuring unidirectional RF transmission over a secure fiber optic link. This prevents signal return, making it ideal for military, government, and secure communication environments.

Secure RF Isolation for Military & High-Security Applications

RF Fiber Breaks are essential for preventing RF signal leakage, ensuring one-way transmission of RF signals over fiber. By eliminating the risk of reverse signal flow, this system provides enhanced security in classified and sensitive environments.

Key Features:

Supports RF frequencies from 45 MHz to 1000 MHz
Prevents return signals for a secure, one-way transmission
Ideal for military, government, and high-security applications
Works over short-distance fiber links
Low-cost, high-reliability RF fiber break solution

Why Choose an RF Fiber Break for High-Security RF Transmission?

Traditional coaxial cabling presents a security risk, as signals can be intercepted or leaked. A fiber-based RF break system eliminates this risk by allowing only forward transmission, preventing any potential RF signal return or intrusion.

2) -  Bi-Directional RF Fiber Break System for CATV – 45-870 MHz (Forward) & 4-45 MHz (Return Path)

Bi-Directional Cable TV RF Fiber Break

PN: F-RF-BR-B includes:

  • 1 CATV RF Forward Transmitter – Converts electrical RF signals into a modulated light signal for secure fiber transport.
  • 1 CATV RF Forward Receiver with Return Path Optical Transmitter – Converts the modulated light signal back into an electrical RF signal and supports return path transmission.
  • 1 CATV Return Path Optical Receiver – Enables bi-directional RF communication over fiber.
  • 2 SC/APC Optical Jumpers – Used to connect the system components for seamless signal transmission.

The F-RF-BR-B Fiber Break is designed for bi-directional RF transmission, supporting a forward path from 45-870 MHz and a return path from 4-45 MHz. This system enables two-way CATV RF communication, making it ideal for on-demand cable TV services while maintaining secure fiber optic transmission.

3) - Satellite RF Fiber Break – F-RF-BR-SAT

Uni-Directional RF Fiber Break for Satellite Frequencies (45-2600 MHz)

The F-RF-BR-SAT is a fiber optic forward optical isolator designed specifically for satellite RF frequencies (45-2600 MHz), providing a secure and one-way RF transmission path over fiber. Unlike traditional CATV RF fiber breaks, this system is optimized for satellite signal transport, ensuring high-security RF isolation in sensitive applications.

System Includes:

  •  PortableSatellite RF Fiber Optic Transmitter – Converts electrical satellite RF signals into a modulated light signal for fiber transport.
  • Portable Satellite RF Fiber Optic Receiver – Converts the modulated light signal back into an electrical RF signal.
  • SC/APC Fiber Optic Jumpers – Connects the TX and RX for seamless signal transmission.

High-Security RF Isolation for Satellite Communications

The F-RF-BR-SAT Fiber Break is ideal for military, government, and high-security applications, where RF isolation is critical. By utilizing a unidirectional fiber link, this system prevents signals from being passed in the return direction, ensuring a one-way transmission of satellite RF signals for enhanced security.

Key Features:

Supports satellite RF frequencies from 45 MHz to 2600 MHz
 Prevents signal return for secure, one-way transmission
 Ideal for high-security and military applications
 Works over short-distance fiber links
Low-cost, high-reliability solution

Why Use an RF Fiber Break for Satellite Signals?

Coaxial cables can present security vulnerabilities in locations handling sensitive satellite communications. Using a unidirectional fiber link eliminates the risk of unauthorized RF interception or return signals, ensuring secure transmission without compromising signal integrity.

Features

  • Low-cost RF Fiber Break for Security Applications

  • All working parameters controlled by a microprocessor

  • Compact Form Factor

  • Single Directional RF Transport
