Cisco Cisco Multimedia Line Equalizer Reverse Conditioner 1 GHz-65 86 Split Data Sheet

 

 

 

 
 
 

The Multimedia Line Equalizer/Reverse Conditioner 
(LEQ/RC) is utilized in the coaxial portion of the HFC plant to 
perform two important functions. 
 
In the forward path, the fixed forward equalizer offsets 
undesirable down-tilt associated with cumulative cable and 
passive losses.  This allows tap port RF levels to be 
maintained within desired design limits even at taps located 
near end of lines. 
 
In the reverse path, the use of plug-in attenuation allows RF 
levels to be conditioned for optimal performance of critical 
reverse path services.  By selectively adding reverse 
attenuation at LEQ/RC locations, the range of RF levels 
transmitted from closed loop customer premise equipment in 
a given service area can be narrowed considerably.  With 
greater percentages of devices such as high speed data and 
telephony modems transmitting in the upper end of their RF 
transmit range, improvements in carrier-to-ingress and 
carrier-to-noise performance can be realized. 
 
 

•  Fixed 9 or 11 dB forward equalizers 

•  Plug-in attenuator location for reverse path optimization 

•  Connection Beam non-interruptible AC/RF bypass maximized network availability during maintenance periods 

•  Equalizer in/out bypass enables reverse conditioning deployment network locations where forward 

equalization is not desired 

•  15 ampere current passing capability enables placement in all portions of the network 

•  6 kV surge protection 

•  Faceplate contained circuit, compatible with existing Scientific-Atlanta line equalizer products 

•  Rugged, polymer-coated housing provides reliable performance in the most challenging of environments
