Data Rates

Q24 Hemispheric mit SD-Karte

Possible Data Rates

The data rates shown in the tables are net data rates, also referred to as the payload, which are given in Mbps (1 byte = 8 bits). In contrast to the gross data rates (including the data load for the operation of the system) that are usually provided when the performance data of DSL connections is specified, for instance, the amount of data shown here is the actual amount of data that is fully available to the end device operated on the Mx2wire receiver unit. As an example, a MOBOTIX network camera only requires a data rate of approximately 2.5 Mbps.

NOTES:

  • When long cables are used, voltage drops may make it impossible to supply end devices with power, so a separate power supply must be provided. In other words, the data range is generally greater than the maximum power transmission line.
  • Only a network patch cable with a usual maximum length of 10 meters should be connected directly to an Mx2wire unit in order to bridge the path to the next device (switch, router, PC, PoE injector or IP camera, for example).
  • No provision is made by MOBOTIX for any further extension of the network, for example, by connecting a longer network patch cable to Mx2wire.
  • It is also not possible to link more than two Mx2wire units.

Mx2wire can also be used to extend the range of an Ethernet connection that would otherwise be limited to just 100 m in length (between the PoE switch and end device). For this purpose, a cat7 installation cable is converted to a two-wire cable as follows: Open the four twisted wire pairs and remove approx. 7 mm of insulation from the ends. Then connect the four white wires together to one cable and the four colored wires together to another cable and attach wire-end sleeves. In conjunction with Mx2wire, PoE class 2 power can be transmitted over a distance of 500 m at a data rate of approx. 30 Mbps.

Mx2wire with Cat-7 network cable

The value for the power transmission capacity of a cable of a particular thickness and length is given as a PoE class. This means that the power supply and full functionality of a PoE end device in the specified class (1 or 2, depending on the cable cross-section and length) is guaranteed on the Mx2wire receiver unit. The sender is the Mx2wire unit that is supplied directly from the PoE switch.

Due to physical constraints, cables exceeding a certain length can still transfer data but not power. When installations have no PoE-supplied end devices (PCs, for example), the range of the two-wire cable may increase significantly, provided that low data rates are sufficient for the application.

NOTE on Data Transfer Rates and Cable Lengths

We have tested the product very carefully and, instead of specifying non-recurrent peak values, we only provide the important net data rate, which was measured over a long period of time. However, we can provide NO GUARANTEE of possible cable lengths, data rates and power transmission , as various physical factors are not within the area of responsibility of MOBOTIX (sources of interference such as machines or power cables, the condition and quality of the cables used, etc.). The nominal data rate, connection length and power transmission can only be individually tested and determined at the place of installation.
