The FX-Rail2N-2Eth-24V is a SHDSL modem that can be used to transmit data over one or more copper wire pairs at up to approx. 15Mbit/s. Depending on the data rate to be transmitted and the available wire cross-section, distances of up to 20km can be covered. The device is suitable for DIN rail mounting.

Brief description

SHDSL modem for Ethernet

System Notes

Connecting several device pairs via the same UTP cable can lead to transmission problems due to crosstalk between the different signals in the cable. Ideally, therefore, each device connection should be realised via separate cables. If several cables have to be connected in series on one connection line, it is important to carry out these transitions as well as possible. This means Ideally, professionally assembled RJ45 plugs are used for the transitions. If this is not possible, for example when using telephone cables, care should be taken to unwind the stranding of the wire pairs as little as possible. The contact between the cores of the cables to be connected must be as good as possible galvanically. Screened UTP cables can cause problems due to equipotential bonding currents. In particular when combining several cables in a central unit, we recommend not to ground the screens in the central unit.

Technical data

Copper Ports
2 x10/100BaseT, RJ45
Extender Ports
2 x 2-wire G.SHDSL, screw clamp
The connection can be used as 4-wire G.SHDSL for point-to-point connections.
Transmission Cable
Twisted-pair data cables, conductor diameter 0.4 to 1.4 mm
Distance Specification
Distances of up to 20 km are possible.
The transmission performance must be considered as a product of the distance and the data rate. If one increases, the other decreases. Here are two examples:

Example 1
Conductor cross-section: 0.8 mm
Distance: 20 km
Max. possible data rate: 128kBit/s

Example 2
Conductor cross-section: 0.8mm
Distance: 1km
Max. possible data rate: 12.8MBit/s

An exact calculation is not possible. Whether a transmission is possible at a given distance and required data rate can only be roughly estimated. Please call us for a consultation.
In addition to the parameters of distance, data rate and wire cross-section, the quality of the existing cables also has a significant effect on the result. We therefore recommend testing a transmission in advance. We would be happy to help you with this.
