Product description
OD007H - optical receiver with integrated wavelength-division multiplexing (WDM) duplexer (in text – receiver) is intended
to convert optical 1550 nm wave lenght carrier to SAT IF and DTT electrical signals and pass 1310 nm & 1480 nm carriers
between COM (common) and BOSA (Bi-directional Optical Sub Assembly) ports bidirectionally. Device is equipped with
AGC based on RF output.
The receiver is powered via RF output connector from STB (Set-Top Box) or external 10-20 V DC PSU (Power Supply
Unit) via DC IN connector.
Device is intended for indoor use only.
Safety instructions
Installation of the receiver must be done according IEC60728-11 and national safety standards.
Any repairs must be done by a skilled personnel.
Supply voltage of receiver is up to 20 V. This voltage is not dangerous for life.
Output of PSU must have a short circuit protection.
To ensure safe operation of the receiver follow these instructions:
Do not plug the PSU into the mains supply until all cables have been connected correctly.
Avoid placing the 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 receiver must be xed with steel screws Ø 2.5-3.5 mm. The screws are not included in a package.
An optical connector after disconnection emits optical radiation.
Avoid looking directly into beam, laser light can cause eye injuries and result in permanent loss of vision.

Installation instructions
Read the product description and safety instruction rst.
Fiber installation should be done very carefully. Bending radius of bers must be not less 25 mm. An optical connector and
adaptors should be cleaned before connecting them. Power on the receiver after all cables have been connected correctly.
Operating
The receiver output level indicator formed from LED:
Glowing green:output level constant 70 dBµV (AGC range), optical input level is in range -15 ...0 dBm;
Glowing yellow:level too low < 70 dBµV, input signal is out AGC range;
Glowing red:level too high > 70 dBµV, input signal is out AGC range.
* optical input signal 4.9% OMI, 1550 nm, 30 SAT IF transponders
** at frequency 1300 MHz
