1 Introduction
This document is the user manual provided with the sat-nms LFTX/RX fibre optical link equipment. It contains all necessary information how to install, setup, and operate the unit. The user manual is available as a printed document and for on-line reading on the optical links itself as well.
The sat-nms LFTX/RX fibre optical link is a high performance transmission system which transmits a complete frequency band, with all its separate carriers, over a single mode fibre with length up to 5km. The big advantages of fibre optical links are:
- Lightning protection
- Fully isolated between the two destinations
- No ground loops
- bug proof
Two types of optical converters are available
- sat-nms LFTX --- optical transmitter which converts from IF input spectrum to optical output at 1310nm
- sat-nms LFRX --- optical receiver which regenerates the optical signal back to an IF spectrum
SatService offer the LFTX/RX modules for different frequency bands.
- sat-nms LFRX-L and LFTX-L --- 950 to 2150MHz
- sat-nms LFRX-B and LFTX-B --- 50 to 2150MHz
- sat-nms LFRX-B and LFTX-W --- 950 to 2450MHz
- sat-nms LFRXO10 and LFTXO10 --- 10MHz only
The paragraphs below give a short overview to the contents of the documentation. A subset of this documentation is stored on the device itself, the complete documentation is available on the sat-nms documentation CD and at www.satnms.com.
- Installation : The installation chapter guides through the installation and setup of the sat-nms LFTX/RX . It describes the mechanical concept of the chassis and the assignment of the connectors. Finally you learn in this chapter how to set the sat-nms LFTX/RX IP address, which is a essential precondition to operate the sat-nms LFTX/RX by means of a web browser. This section is available in the printed version only.
- Operation : The sat-nms LFTX/RX is operated using a standard web browser like the Internet-Explorer or Mozilla Firefox. The user interface design is straight forward and clearly structured. Operating the sat-nms LFTX/RX is mostly self-explanatory. Nevertheless, the 'Operation' chapter outlines the map of web pages which make up the sat-nms LFTX/RX user interface and elaborately describes the meaning of each alterable parameter.
- Remote Control : The sat-nms LFTX/RX provides a versatile remote control interface. A monitoring & control software may fully operate the sat-nms LFTX/RX either through a TCP/IP network connection or through the RS232 interface of the sat-nms LFTX/RX. This chapter describes the communication protocol used for remote control and 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 LFTX/RX are summarized in this chapter.
