Specific Safety Instructions - Triax OTX 1310 Manual Del Usuario

SAT Fibre Headend OTX 1310 and OTX 1550

The location for the SAT FO Headend OTX has been selected.

SAT Wideband LNB TWB 40 has also been installed following its separate user manual.

The passive optical network (PON) has been planned and installed correctly; using TRIAX approved
optical couplers and cables.

All ferrule end faces of the FC/PC optical connectors are cleaned prior to making a connection using a
suitable fibre.

Specific safety instructions


Never connect the PSU on mains before all cables have been connected to the OTX unit completely.

Never look with into a fibre core line or fibre connector that is operating with a laser transmitter like in
the OTX. The laser light is not visible but can harm the eye. Take also care for Laser Class 1 in EN 60825-
1.

Do not connect unfiltered terrestrial antennas directly to the port labelled FM/DAB/DTT.

Not used F-connectors shall be closed with DC blocked 75 Ohm terminator like TRIAX RFC 75 DCB
(350659).

The OTX unit needs to connect with the wire for potential equalization of the building!
The grounding cable can be clamped with screw and tooth washer onto a fasten hole in the feet of the
OTX unit or the OTX is mounted on a grounded mast or base plate.
Installation
TRIAX recommends locating the OTX unit in a dry room or cabinet. Alternatively outdoor installation is possible i.e.
directly onto the pole or mast behind a dish by using the mounting bracket (see below, order separately) and the
fibre and coaxial connectors should be water proofed e.g. by gel boot and amalgamating tape.
Optical connection

Clean the output fibre optical connector and check the optical power using a suitable optical power
meter. Optical power out of the OTX should be +8dBm ±0.5dB.

Clean the optical connector of the patch cable and connect it to the optical output of the OTX unit,
ensuring the keyway is aligned.
Coaxial connections

Ports labelled V or H should be connected to a suitable wideband LNB (recommended TRIAX TWB 40)
ensuring correct polarizations are connected to the relevant ports. Voltage is supplied for LNB powering
V: +12V, H: +20V. Maximum current 500mA incl. Terrestrial.
