ALLNET Point-to-Point Coax 8 Port Master Chassis "ALL-GHN108M-Coax" without modules

The distribution amplifier ALL-GHN108M-Coax is a highly integrated solution to provide a Gigabit network on 8 coaxial lines. Up to 8 G.hn modems deliver 750 Mbit or 1700 Mbit net per coaxial strand, depending on the model. A built-in power meter simplifies service during and after installation. Without compatibility to a cable network operator, even up to 1700 Mbit is available. Signal strength and skew can be digitally adjusted. If compatibility with a cable network operator is required, 750 Mbit are available. The ALL-GHN108M-Coax takes over all tasks such as filling, amplifying and splitting the TV signals as well as inserting the G.hn network data. Elaborate mounting boards / installations are not necessary.

The chassis are available for EOC-Ethernet over COAX with 100MHz modules for DVB-C coexistence and as 200MHz with more bandwidth without DVB-C coexistence. Or explained differently.

The EOC 100 and EOC 200 differ as follows:

EOC 100 1 Gbit/650 Mbit (gross/net).

EOC 200 2 Gbit/1.7 Gbit (gross/net)

EOC 100 and EOC 200 - What's behind them !

The EOC 100 uses the frequency band 2-87 MHz for data transmission and can provide the broadband cable signal (DVB-C) from 88 to 860 MHz, so that the cable connection of your provider can still be fully used.

The EOC 200 uses a frequency band of 2-199 MHz. Ideal for operators of a head-end station who want to change their frequency allocation.

Technical Details:

  • Remote power supply 24 V up to 40 EOC100 (Part No: 221230 ALL-GHN108S-100-UP-Dose  or Part No: 221231 ALL-GHN108S-100-WIFI)
  • Digital adjustable:
    •         8x 31 dB attenuator (0.5 dB steps)
    •         Skew correction (0-3-6-9 dB)

 

Important: Setting the output power

The total band power (approx. 90 transponders) is 19.5 dB higher compared to the output power of a single transponder determined with a measuring device!

You must take this into account when making the setting!
Example 1
1 transponder:
80.0 dBµV measured
90 transponders:
99.5 dbµV Band power

The LED display on the unit shows 99 dBµV.

Result: The input signal can (only) be amplified by 10 dB.
Example 2
1 transponder:
90.0 dBµV measured
90 transponder:
109.5 dbµV Band power

The LED display on the unit shows 109 dBµV.

Result: The input signal cannot be amplified any further.
Consideration for 5 flush-mounted boxes in the line:

    Good television reception requires 60 dbµV - 75 dbµV at the input.
    An EOC 1000/EOC 2000 flush-mounted box has a throughput attenuation of 2-3 dB and an outcoupling attenuation of 18 dB.
    The AMP X8 delivers a maximum of 110 dbµV per line.

After 5 EOC 1000/EOC 2000 flush-mounted boxes connected in series, the total attenuation is:
4x3
dB
Continuity attenuation
+
18
dB
Outcoupling attenuation
+
4x1-2
dB
Attenuation in coaxial cable
=
34-38
dB
Total attenuation

An optimum setting on the AMP X8 would then be:
60 bµV-65 dbµV + 38 dB = 98-103 dbµV.

The output of the first socket would then be 12 dB, i.e. 72 bµV-77 dbµV.
