Excellent suitable for EOC = 'Ethernet-over-Coax', powerline over Coax 1

I put some KATHREIN ESM 40, 41 and 42 here in my apartment, and am therefore fully satisfied. The special feature is that I have built up my coax cable for TV and radio a very fast Ethernet network, modern powerline adapters to the HomePlug AV2 standard (up to 500 Mbit / s), but with an additional coax output. I reach so net-transfer speeds up to 250 Mbit / s, a 2 GB media file can be transferred in less than 2 minutes, impossible to reach by wireless.

The apartment is furnished a total of two coaxial cables, hung with three to four doses in series. Since the power line modem hang at the ends of the strands, the Ethernet signals must (frequency range 2-68 MHz) with all doses through to get to a modem on the other hand, therefore a low transmission loss for each individual box is very important.

The KATHREIN canned the ESM Series feature two directional coupler, in addition the signal of the two directional couplers via a downstream diplexer in TV and radio signal is divided, which is very useful. The transmission loss of the doses is therefore compatible low, yet stands at the F-connector (for the multimedia modem) the full frequency range (with return channel) a second time available. One can therefore operate on F-connector of the cans also a second TV (eg Blu-ray player with built-in DVB-C tuner) if there is no modem is used for example.

Especially the ESM 42 with 10 dB tap loss is also very good as a replacement for one of the rear doses of a house wiring in the only standard doses were used with 14 dB Tap loss (standard in most major Mietkomplexen, eg ESD 44), if there the should be a bit too weak signal (terminator remember if it's the last box, or use 40 ESM). By 4 dB lower connection loss the signal will then be much stronger, but of course also increases the transmission loss and the signal quality down to the last doses suffers something that must be considered in any case.

The box is designed smart and a good solution for the requirements in modern apartments, for a full 5 stars from me!
