sat-nms LFTX/RX L-Band Fiber Optical Transmitter/Receiver

The sat-nms LFTX/RX L-Band Fiber Optical Transmitter/Receiver System, manufactured by SatService GmbH, is a high-performance solution for analog multi-carrier RF signal transportation over fiber optical media. Designed for scalability, flexibility, and redundancy, this system is suitable for a wide range of satellite communication and broadcasting applications.

System Overview

The system consists of two key components:

1. sat-nms LFTX Optical Transmitter: Converts the RF input spectrum into an optical output signal at 1310 nm.
2. sat-nms LFRX Optical Receiver: Regenerates the optical signal back into an RF spectrum.

These modules are available as standalone units, integrated into 2RU 19” rack-mount chassis, or housed in outdoor cabinets for external use. The system is designed to support N:1 or 1:1 redundancy switching, providing robust and reliable performance.

Frequency Band Options

SatService offers the LFTX and LFRX modules for various frequency ranges:

• sat-nms LFTXL and LFRXL: 950–2150 MHz.
• sat-nms LFTXB and LFRXB: 50–2150 MHz.
• sat-nms LFTXO10 and LFRXO10: 10 MHz.

Key Features

• High-Performance Optical Link:

  • Ensures reliable RF signal transportation over fiber optic media.
  • Designed for multi-carrier analog signals.

• Redundancy Options:

  • 1:1 or N:1 redundancy switching for uninterrupted operations.
  • Redundant configurations enable seamless failover.

• Flexible Chassis Configurations:
