    An exceeded attenuation budget usually results in interferences in your TV picture. devolo dLAN 200 AVpro adapters provide an attenuation budget for the dLAN signal of more than 60 dB. Thus, a dLAN data signal fed in behind the amplifier will still be available at full capacity at the farthest socket.

  • Page 16: The Deployment Of Devolo Dlan Technology In Antenna Networks

    The deployment of devolo dLAN technology in antenna networks devolo dLAN 200 AVpro technology transports data in 2 to 30 MHz frequency band. TV or radio signals are not normally allocated to this frequency band in the antenna network, and it can therefore be used for data traffic. You need to take account of the fact that the signals are bidirectional here, whereas TV and radio signals only move in one direction (downstream).

  • Page 17: Coupling The Ethernet Signal To The Antenna Cable

    3.5.1 Coupling the Ethernet signal to the antenna cable The illustration filter below shows an example of coupling the devolo dLAN 200 AVpro signals onto the antenna cable on the main distribution (Master). This can be achieved with a diplex filter (reverse path combiner). On the one hand, the high-pass filter prevents signals radiating in the direction of the cable network operator, and, on the other, it prevents neighbouring segments from "seeing"...

  • Page 18: Tapping The Ethernet Signal On The Antenna Socket

    In each of these cases, we urgently recommend finding out the exact component designation (e.g. ESD30) and researching the technical data on the web. This will provide you with the frequency responses and attenuation values. devolo dLAN® 200 AVpro Project Manual...

  • Page 19: Bypassing Amplifiers (Passive Bypass)

    Deploying diplex filters is favourable to the data connection's attenuation budget. For TV, a pass-through attenuation of approx. 2 x 0.5 dB (diplex) + 2 x 0.8 dB (high- pass) should be taken into account.

    Fig. 3-14: 3-level amplifier cascade with passive bypass 3.5.4 Bypassing amplifiers (active bypass) The amplifier is bypassed using two devolo dLAN 200 AVpro adapters and an Ethernet cable. Make sure that there is enough stop-band attenuation on the diplex filters (e.g. Comega, ) here. Frequently, they only have 35dB stop-band attenuation.
