To connect the TRIAX OTX 1310 SAT FO Transmitter, follow these steps:
1. Optical Connection:
- Clean the output fibre optical connector and check the optical power using an optical power meter. The 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.
2. 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. The TWB 40 LNB is voltage supplied by the V- port of the OTX.
- Port labelled FM/DAB/DTT input should be connected to the terrestrial antenna system. Use appropriate antenna combiners, LTE filters, or selective pre- or multiband amplifiers for optimum performance and sufficient LTE protection.
3. Powering:
- The FO Headend OTX, including the wideband LNB, can be directly powered on the F-connector power input using the PSU +20V TPS 323.
- The mains adapter (PSU) is the disconnect device for OTX and TWB unit. Ensure it is easily accessible.
- The LED on the OTX indicates correct powering of the unit. The LED should be a constant green.
Please refer to the TRIAX OTX 1310 SAT FO Transmitter User Manual for more detailed instructions and safety precautions.
