Page 4: Description
Description: First of all thanks for buying this product from BSRF, we hope it will serve you well! The BSRF radio over fiber products are used to take advantages of propagation on optical fiber. Those devices are used to convert RF electrical signal to optical signal and convert them back to electrical. -
Page 6: Question Answer About Rof
Question answer about RoF. 1. Does it work like network devices ? NO, it's an analog modulation, you've to pay attention on optical loss. As a rule of thumb every time you loose 1dB on the optical path you'll loose 2dB on RF path. 2. - Page 7 antenna to « select » area of coverage. 6. Can I consider not inspecting fiber before an installation ? It's the same when you wear glasses, generally it's quite hard to clean them when you drive... Seriously it must be done before an installation with proper tools.
- Page 8 WARNING!: DON'T TRY TO INSPECT FIBER WITH YOUR EYES WHEN THE UNIT IS SWITCHED ON, USE PROPER PERSONNAL PROTECTION EQUIPEMENTS. The AFB-250 allows to remote two RX antennas over two momode fibers. Specially made electro-optical components are used in this equipment.

This means above a threshold the more the signal become strong the more it will produce distrortion, noise. => RF in ports must be preserved from high signal, on AFB-250 the RF peak led l lights up at -12dBm, keep signal under this threshold (specially when using many carriers). - Page 21 area (in the line of sight) it won't work! Antennas from the same diversity channel (A or B) must not see each others. Use directive antennas to avoid such event. 5) Recommended tools ?
