|Systemhinweise||Operating several VDSL lines over the same cable can lead to transmission problems due to crosstalk between the different signals in the cable. Ideally, each device connection should therefore be implemented using separate cables.
When using several VDSL SFPs in one switch, problems with ground loops may occur, depending on the switch.
If several cables have to be strung together on a connection route, it is important to make these transitions as technically sound as possible. This means that ideally, professionally assembled RJ45 connectors are used for the transitions. If this is not possible, e.g. when using telephone cables, it is important to ensure that the stranding of the wire pairs is carried out as little as possible. The contact between the cores of the cables to be connected must be as good as possible galvanically.
Shielded cables can cause problems due to potential equalization currents.
In installations, especially in outdoor areas, it is recommended to protect the devices on the line side with an overvoltage protection. We recommend the products of DEHN + SÖHNE GmbH + Co.KG for this purpose.
|supply voltage||Power is supplied via the SFP slot of the switch or media converter.|
|operating temperature||-20°C .... 75°C|
|dimensions||SFP box, 80mm x 14mm x 17mm (LxWxH)|
|copper ports||SFP-Port: The SFP port used must be permanently set to 1GBit/s.|
|extender ports||1 x VDSL2, RJ45|
|transmission cable||Copper cables per pair, e. g. Cat3 telephone cable|
The potential distance depends on the quality of the cable used. Older or damaged cables can cause a reduction in distances. Larger wire cross-sections are advantageous, smaller ones are disadvantageous.
The values indicated are indicative values without guarantee, measured on a Cat3 telephone cable.
|SFP for the central side
This SFP does not match with PD-VDSL-2402.
|SFP for the remote side, e. g. camera side
Use this SFP as a connector to PD-VDSL-2402
