inverto 6125 Unifiber Quattro Optical Receivers User Manual
PRODUCT DESCRIPTION
The optical receivers 6125/ 6126/ 6131/ 6132 ( are intended to convert optical signals into electrical RF signals. The recivers are compatible with Inverto wideband SAT IF transmitting system.
The receiver is equipped with AGC system based on optical input level (OLC – optical level control). The product is intended for indoor usage only.
SAFETY INSTRUCTIONS
- Installation of the receiver must be done according IEC60728-11 and national safety standards.
- The receiver is powered from low DC voltage, which is not dangerous to life.
- Any repairs must be done by a skilled personnel.
To ensure safe operation of the receiver follow these instructions:
- Do not connect supply voltage until all cables have been connected correctly.
- Receiver shall not be exposed to dripping or splashing water.
- Avoid placing receiver next to central heating components and in areas of high humidity.
- If the receiver has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before powering.
- The ventilation should not be impeded by covering receiver with items, such as newspapers, table-cloths, curtains.
- Avoid looking directly into beam, laser light can cause eye injuries and result in permanent loss of vision.
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.
This product is in accordance to following norms of EU: EMC norm EN50083-2, safety norm EN62368-1 and RoHS norm EN50581.
This product is in accordance with Custom Union Technical Regulations: “Electromagnetic compatibility of technical equipment“ CU TR 020/2011, “On safety of low-voltage equipment“ CU TR 004/2011.

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.
- All unused F type connectors must be terminated with 75 Ω loads.
- Mount receiver in vertical position with optical connector underneath.
- From top, left and right side leave 10 cm free space.
- Fasten with screws. Screws are not included in a package.
Powering
The receiver can be powered in two ways: from AC/DC adapter through 3.5/1.3 DC connector (pos.9, Figure 1) or through RF outputs (pos. 3, 4, 5, 6, 10, 11 Figure 1).

Optical input and RF outputs
The operational optical input level of the receiver is -15…-5 dBm. In this
region OLC is working and provides fixed RF output levels. Ensure optical
input level in this range.
A direct optical connection cannot be made between the transmitter and the
receiver. Use appropriate optical attenuator.
Requirements for external power supply unit (PSU)
