User Manual 

LBON4000 

The Lindsay Broadband Inc. LBON4000 is a 
hardened outdoor, high output, 2 or 4 output, 
optical fiber node capable of up to 52dBmv 
with 2 outputs and 48dBmv with 4 outputs at 
1002MHz .  Advanced GaAs-FET technology, 
achieve excellent distortion performance at 
High output levels with low power 
consumption. LBON4000 is designed to carry 
advanced video and data traffic to the HFC 
Network (Single Family homes, MDU, Office, 
and University locations.  
 
The LBON4000 offers flexibility in choice of 
wavelength, laser type and band splits for 
maximum application.
