PREFACE
1. Preface
This manual describes the QFQR 200A-04 rack mount quad return path optical receiver features, specications, installation,
adjustment and maintenance procedures to install this receiver successfully and use it safely. Users must read the manual
carefully before installation, and perform the installation and adjustment according to this manual. Otherwise, some practices
or circumstances may lead to damage or personal injury. Please contact ATX Networks Technical Support if you should have
any questions.
Important User Information
• Caution: Invisible laser radiation is emitted from ber optic connectors which connect to this unit, exposure can
cause permanent injury to skin or eyes.
• Make sure the case and the power supply are grounded well before powering on the receiver (grounding resistance
should be less than 4Ω) so as to prevent static from damaging the photodiode and injuring user.

6.1. Supplies & Tools
An optical power meter
A digital multimeter
A frequency analyzer
A standard ber test jumper (FC/APC or SC/APC)
Denatured or 99% pure isopropyl alcohol and lint-free ber optic cleaning wipes
6.2. Installation
a) Install the receiver into a standard 19” rack and ground the case.
b) Check voltage with a digital multi-meter in accordance with power requirements.
c) Make sure the ber connector is clean and verify the input optical power is normal by means of optical power meter
(0 dBm to -10 dBm recommended), then insert the ber connector into the ber adaptor.
d) After powering on the receiver, check the power and optical power LED indicators to ensure normal operation.
Troubleshooting during installation:
• RF Output Low: Check the connection of RF adaptor and the coaxial cable.
• No RF Output: Check the optical power indicator. If Red, check the optical input power.

CLEANING & MAINTENANCE
7. Cleaning & Maintenance
Fiber connectors can be easily contaminated by dust or dirt, which can result in decreased optical input power. If optical
receiver power and RF output levels of the receiver decline, you should clean ber connectors. The cleaning method is
recommended below:
a) Remove power from the receiver.
b) Carefully unplug the ber connector from the adapter.
c) Using isopropyl alcohol and lint-free wipes carefully clean the faces of the optical connector. After cleaning,
allow 1 to 2 minutes until the connector’s surface is dry.
