The module includes a Tx and a Rx module

TX --- optical transmitter which converts from IF input spectrum to optical output at 1310nm
RX --- optical receiver which regenerates the optical signal back to an IF spectrum

SatService offer the LFTRX modules for different frequency bands.

sat-nms LFTRX-B --- 50 to 2150MHz

sat-nms LFTRX-L --- 950 to 2150MHz

sat-nms LFTRX-10 --- 10MHz only

Installation

 : The installation chapter guides through the installation and setup of the sat-

nms LFTRX. It describes the mechanical concept of the chassis and the assignment of the
connectors.

Operation

 : Operating the sat-nms LFTXR is mostly self-explanatory. Nevertheless, the

'Operation' chapter outlines the sat-nms LFTRX user interface and elaborately describes
the meaning of each alterable parameter.

Remote Control

 : The sat-nms LFTRX provides a versatile remote control interface. A

monitoring & control software may fully operate the sat-nms LFTRX through a analog
interface. This chapter lists all parameters accessible through the remote interface.

Theory of Operation

 : This chapter gives a short overview how the optical links work and

which features are supported.

Specifications

 : At the end of the document, the specifications applicable to the sat-nms

LFTRX are summarized in this chapter.
