Introduction
The purpose of this guide is to enable the successful installation of the TRIAX SAT Fibre Optic System, utilizing the
OTX at the SAT fibre optic headend. Please read and follow to the advices comprehensively.
Functional description
The SAT FO
Transmitter
OTX has two coaxial RF inputs for connecting with the vertical and horizontal SAT-IF signal
cables coming from the wideband LNB TRIAX TWB 40 (307784) with LOF 10,41 GHz. The LNB is voltage supplied by
the V- port of the OTX. The OTX unit consists of the frequency stacker for the H,V and TER RF bands and the optical
transmitter. The OTX can drive a PON (Passive Optical Network) with optical split up to 32 outlines where the TRIAX
optical re-converters TVQ 06, TVC 06 and TOM 08 M/S can be connected directly.
Fig. 1 Typical connections with Fibre Optic Headend OTX
OTX 1310 designed with a 1310nm laser transmitter supports standard applications like shown in fig.1. The OTX
1310 can drive Passive Optical Network (PON) with up to 32 fibre lines directly. The network can be expanded by
using of active FO Repeaters TRIAX OTO 32 (order separately).
OTX 1550 with 1550nm laser transmitter is recommended for large installations using EDVAs for enabling of very
high optical splitting rates in the optical network. The 1550nm variant of the OTX is also appointed for WDM
operation in GPON or EPON in order to combine SAT reception with data service applications.
This guide assumes that:
The installation is carried out by a competent person.
A site survey has been completed; the location for dish has been chosen and the dish has been installed.
