Cisco 4036771 network equipment spare part Reverse equalizer

Reverse equalizers produce a tilted frequency response opposite of that produced by coaxial cables. They are normally used during station balancing to counteract the tilt produced by coaxial cables, in order to achieve desired tilt. An equalizer’s “dB value” indicates the amount of tilt (in dB at rated high frequency) the equalizer is designed to offset. The dB value and rated high frequency (40, 42, 55, 65 or 204MHz) are printed on the top of each equalizer. The amount of tilt (in dB) that the equalizer produces from low to high frequency is printed on the side of each equalizer. 85 MHz EQs Are Used in GainMaker Amplifiers with a 85/102 MHz Reverse/Forward Bandsplit.
