ALLNET Point-to-Point Coax 8 Port Master Chassis "ALL-GHN108M-Coax-200" 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-200 takes care of 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) see (Part No. 193132)

EOC 200 2 Gbit/1.7 Gbit (gross/net) see (Part No. 221624)

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

The EOC 100 uses the frequency band 2-87 MHz for the transmission of data 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 headend

  • Digitally adjustable:
    • 8x 31dB 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 adjusting the total band power.

Example 1

1 transponder:
80.0 dBµV measured
90 transponders:
99.5 dbµV tape power

The LED display on the device shows 99 dBµV.

Result: The input signal can be amplified (only) by 10 dB.

Example 2

1 transponder:
90.0 dBµV measured
90 transponders:
109.5 dbµV tape power

The LED display on the device shows 109 dBµV.

Result: The input signal cannot be further amplified.

Consideration for 5 in-wall sockets in the line:

  • Good TV reception requires 60 dbµV - 75 dbµV at the input.
  • One in-wall socket EOC 1000/EOC 2000 has a transmission loss of 2-3 dB and a decoupling loss of 18 dB.
  • The AMP X8 delivers a maximum of 110 dbµV per strand.

After 5 EOC 1000/EOC 2000 in-wall sockets connected in a row is the total attenuation:

4x3
dB
Transmission loss
+
18
dB
Decoupling attenuation
+
4x1-2
dB
Attenuation in the coaxial cable
=
34-38
dB
Total attenuation

Then an optimal setting on the ALL-GHN108M-Coax-200 would be:
60 bµV-65 dbµV + 38 dB = 98-103 dbµV.

At the first in-wall socket, 12 dB would then arrive at the output, i.e. 72-77 dbµV.
