Terra OD006, OD006-55 Quick Start Manual
Optical receivers OD006, OD006-55
Product description
Optical receivers OD006, OD006-55 (in text – receivers) are intended for FTTH (Fiber to the Home) applications to
convert signals from optical to electrical and amplify them. Devices are equipped with AGC based on optical input level and
optical input power indicator.
OD006-55 has integrated 1550 nm optical lter for WDM (Wavelength-Division Multiplexing) systems.
The receivers are powered from 5 V DC PSU (power supply unit) as well as TV set, set-top box or other USB port.
Devices are intended for indoor use only.
Suitable for moderate and tropical climates.
Safety instructions
Installation of the receiver must be done according IEC60728-11 and national safety standards..
Any repairs must be done by a qualied personnel.
Output of PSU +5V 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;
to disconnect the receiver completely, disconnect the PSU +5V from the mains or unplug USB cable;
the mains socket must be easily accessible;
receiver shall not be exposed to dripping or splashing water and no objects lled with liquids, such as vases, shall be
placed on it;
avoid placing the receiver next to central heating components and in areas of high humidity;
no naked ame sources, such as lighted candles, should be placed on receiver;
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
plugging into the mains;
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.

Operating and adjusting
Optical Level Control (OLC) is active at optical input power -6 .. 0 dBm. RF level remains constant while optical input power
uctuates in range of -6 .. 0 dBm. Out of this range receiver continues to operate though OLC is disabled.
The receiver owns optical input power indicator formed from 3 LED. Note the table below for detailed description.
Indication
