The number of fiber optic connections in Germany is growing steadily, but so far it has not been used everywhere where a fiber optic connection has been installed in the house. Fiber optic providers lay the fiber optic connection with an optical network termination (ONT) at the house transfer point, usually in the basement or house connection room.
The router is usually unfavorable at the ONT
The router must be connected to the ONT using an Ethernet cable so that it is usually in a location that is unfavorable for WLAN and DECT, namely also in the basement or house connection room, where it is not needed. However, if the router is to be placed in a different, more central location in the house, the homeowners themselves have to take care of the necessary work for laying the cables between the ONT and the router. Devolo now wants to counter this problem in the last few meters between the fiber optic connection and the router with the Giga Bridge by tapping the signal directly at the ONT and thus before the router and forwarding it via old, existing wiring in the house.

In single-family homes, the IP bridge enables the signal to be transmitted at gigabit speed over an existing, free telephone or coaxial cable, which usually also begins where the fiber optic connection is, to the desired router location. The existing telephone cable can be wired with two or four wires. It is important that the cables are unused and not required for any other purpose.
In order to transport the signal either via telephone or coaxial cables that have already been laid, an adapter from the Devolo Giga Bridge set is placed near the ONT and connected to it via an Ethernet cable. Using suitable connectors for the existing telephone or coaxial cable, the signal is fed in via the F socket or the RJ45 telephone port and picked up by the second adapter of the set elsewhere via this same medium, i.e. the telephone or multimedia socket. The second adapter in turn forwards the signal via Ethernet to the router, which can now be placed in a more suitable location. The pairing between the adapters takes place automatically and the data is transported over the lines by the bridge using the G.hn standard. Thanks to the integrated socket in the adapter, none of these are lost at either point.

Since the Devolo Giga Bridge is used in front of the router, Devolo designed it in such a way that it is completely invisible from the outside. Communication between the adapters is secured by 128-bit AES encryption.
High speeds even over long distances
Internal tests at Devolo confirm that this solution still has a net transmission rate of 800 Mbit/s even on a coaxial cable length of 200 meters. Around 1 Gbit/s is maintained over short distances.
199.90 euros and optional installation service
Devolo offers the Giga Bridge in two different sets, depending on whether the data is to be transmitted over a telephone or coaxial cable. The two sets differ in the supplied adapter pieces for connecting the Giga Bridge to the existing cabling. Both sets cost 199.90 euros and are available immediately. Those who do not trust themselves to connect and install the Giga Bridge can book an installation service from Cervis at Devolo for 99.90 euros. This price includes the arrival and departure of the technician as well as 45 minutes on-site installation. Devolo also offers installation videos for both the coaxial set and the telephone set. The warranty on the Devolo Giga Bridge is three years.
