The transmitting system

OPTICAL TRANSMITTER: 6111 (1550NM) / 6112 (1310NM)
DTT PROCESSING UNITS: 6118 (UHF 470-790 MHZ) / 6119 (UHF 470-694 MHZ)
WIDEBAND LNB: 6116 (10.40 GHZ LO) / 6117 (10.41 GHZ LO)

SYSTEM DESCRIPTION

The optical transmitter (6111/6112) is intended to distribute SAT IF and DTT, FM, DAB signals through a fiber optic. Transmitted SAT IF signal 290-2350 MHz is collected from wideband LNB, DTT, FM, DAB signals are collected from DTT processing units (6118/6119).

SYSTEM DESCRIPTION

This optical transmission system is not compatible with optical receivers of other manufacturers with similar functionality. The transmitting system is only compatible with Inverto optical receivers.

SAFETY INSTRUCTIONS

Installation of the products must be done according IEC60728-11 and national safety standards. The products are powered from 10 – 20 V DC. This voltage is not dangerous to life. Any repairs must be done by a skilled personnel.

To ensure safe operation of the products follow these instructions:

Do not supply power until all cables have been connected correctly.
To disconnect the products completely, disconnect plug of power supply from the mains socket.
The mains socket must be easily accessible.
Avoid placing the products next to central heating components, near highly combustible materials and in areas of high humidity.
The ventilation should not be impeded by covering the products with items, such as newspapers, table-cloths, curtains.
From top, front and bottom of installed products must be at least 5 cm free space.
The products should be mounted with connectors underneath to avoid the water ingress inside.

SAFETY OF LASER PRODUCT

Optical transmitter module contains laser diode sources. These devices are rated under IEC60825-1:
“Safety of Laser Products”, Part 1: Equipment classification and requirements as CLASS 1M laser product

When operating the equipment note the following:

Most fiber optic laser wavelengths are totally invisible to the eye and will cause permanent eye damage. Never look into the end of a fiber on a powered device through a magnifying device (microscope, eye loupe, magnifying glass, etc.). Before using such devices always double check that power is disconnected or, if possible, completely disconnect the unit from any power source.
To verify the light output always use an instrument, such as an optical power meter.
Operate only with the proper optical fiber installed in the device optical connector.
Whenever the optical connector is empty the laser transmitter should be turned off.
Before applying power always connect a fiber to the output of the device.
Never leave equipment with radiating bare fibers accessible – always cap the connectors.

This product complies with the relevant clauses of the European Directive 2012/19/ EC. The unit must be recycled or discarded according to applicable local and national regulations.

Equipment intended for indoor usage only.

Functional grounding. Connect to the main potential equalization.

OPTICAL CONNECTIONS

Note: All optical connectors and adaptors should be cleaned before connecting them.
If optical reception power of the receiver decrease, fiber connection should be cleaned and maintained.
Reel cleaners or prepackaged lint free wipes or swabs with alcohol are the most convenient means of cleaning optical connectors.
Fiber connectors should never be left uncovered

Align the FC/UPC connector key-way (type R) with the receptable key-way
Push firmly to locate the key-ways and then rotate the coupling ring.
Do not exceed the minimum bending radius of fibers: must be not less 30 mm when connecting optic cable to the system.

INSTALLATION INSTRUCTIONS

Read the safety instruction first.
The unit is dedicated for indoor installation and shall not be exposed to dripping or splashing water.
For outdoor installation use appropriate box. We recommend to put this box in shadow of the SAT dish to protect from direct sun radiation. The laser is highly sensitive to overheating.
