STARLINE Cable Equalizers

Select the appropriate model SFE-100-* to compensate for cable attenuation versus frequency and to obtain the proper output tilt. The BLE100 is equipped with the LDR/9/1G interstage equalizer and flatness board that compensates for cable attenuation. Any cable or passive slope beyond that of the LDR must be compensated for by selecting and installing the appropriate SFE-100-* cable equalizer.

Equalizers are available in 1 dB increments from 0 dB through 22 dB. The following examples describe how to choose the correct equalizer.

Example 1

The amplifier location includes 20 dB of cable (at 1 GHz) between its input and the preceding amplifier. Consider cable loss only. Exclude any flat loss due to splitters or other passive devices. The internal equalizer, model LDR/9/1G, compensates for approximately 9 dB of cable. Subtract this cable length from the 20 dB of this example (20 – 9 = 11). The SFE-100-11 is the proper equalizer in this case. With this equalizer installed, the BLE100 reproduces the output tilt of the last upstream amplifier.

When selecting an equalizer, choose the next lower value if the exact value is not available or in cases where the calculated value makes two choices possible.

Example 2

The BLE100 is used in a link following a fiber node with flat output. There is 18 dB of cable between the node and the line extender, plus passive losses that are assumed to be flat. Which is the proper equalizer to achieve the 10 dB of output tilt?

In this case, calculate the equalizer value by using the following method:

 

SLOPEeq

= TILTout + SIGlo – SIGhi – SLOPEieq

where:

SLOPEeq

= required SFE-100 slope

 

TILTout

= required amplifier output tilt

 

SIGlo

= signal input level at channel 2

 

SIGhi

= signal input level at 1 GHz

 

SLOPEieq

= interstage equalizer slope (9 dB)

From various references, such as manufacturer’s catalogs, you can determine that 18 dB of cable at the operating frequency of 1003 MHz is 4 dB of loss at 54 MHz. This suggests that the channel 2 signal input level to the line extender is 14 dB greater (18 – 4 = 14) at channel 2 than it is at 1003 MHz. Our example assumes that the high-end frequency level into the amplifier is +15 dBmV.

Substituting this information in equation (1) provides the following result:

10.0 dB + 29 dB – 15.0 dB – 9.0 dB = 15 dB
