Most questions proposed by our customers can find answers in this section. If you need further assistance you can contact us directly by completing the following information
Channel Mode (CH) and Permanent link (PL). In CH mode, the patch cords the user will need at both ends of the link are provided. In PL mode the end patch cords are not provided (this is the most common form of measurement).
It is the cable's nominal propagation speed (Nominal Velocity of Propagation). This value is specified by the manufacturer for each cable. It has to be introduced in the measuring equipment so that it can display both the correct measured length of the data cable and the exact point of failure when applicable.
The most common errors we can find in twisted pair cabling are: - Installation errors, Inadequate connections, Distorted twisting index for each pair, Connectors that do not meet the required transmission quality level, Incorrect certifier configuration, Manufacturing defects or damage of the installed twisted pairs, Defective patch cords. For all these reasons, it is essential to have every data network certified.
The dimension of the modules of a rack is stated in "heights". One "height" is equivalent to 43.5 mm. For example, a 19" sub-rack ", ref. 5301, is 5 "heights" (217.5 mm).
All. We should be meticulous when performing the connector termination, and be careful not to make loops and reels too tight. When building the connectors, the unwinding of the different cable pairs should be handled with special care not to unwind too big a portion of the cable pair.
Not always. Among the devices provided with the Dinova antenna, there is actually a power supply unit. In case of an installation that includes distribution, an active power supply may be required, since the gain it provides allows for the distribution of the signal towards multiple reception points. However, for installations involving just a receiver and an adapter (portable installations), a zAs adapter could power the Dinova antenna without the need for an extra power supply.
Operators frequently change frequencies and other transmission parameters. As a result, the new transponders and their associated parameters need to be memorized again in the receiver's memory. To do this, make an automatic search with the help of the equipment's instructions manual. If the new frequency was not stored in the receiver's database, a manual search for the specific frequency will have to be carried out.
A data cable is an information transmission media made of four helically interleaved copper wires. In this way, interference is reduced and data transmission improved.
Based on transmission speed and international standards TIA/EIA-568 and ISO/IEC 11801 (Cat. 7), data cables are classified as:
Cat. 5:
Cat. 5e:
Cat. 6:
Cat. 6a:
Cat. 7:
maximum
speed of
100 Mbps
with a
100 MHz bandwidth.
an evolution
of the previous one reaching 1000 Mbps
(ref.: 219502, 219602, 219701).
up to 1 Gbps with a 250 MHz bandwidth (ref.: 212101, 212201, 2123, 212302, 212310, 2199).
an evolution of the previous one reaching 5 Gbps with a 500 MHz bandwidth
(ref. 219301).
maximum
speed of
10 Gbps with a 600 MHz bandwidth
(ref. 219101).
Based on the shielding type and the ISO/IEC 11801 standard, they are classified as follows:
When it comes to checking the technical characteristics of coaxial and data cables, you may find the “CCA” abbreviation in the specifications. You should distinguish between CCA and Cca as explained below:
CCA
This abbreviation refers to the material type of the cable’s inner conductor (Copper-Clad Aluminium). Compared with copper or copper-plated steel, two of the most widely used materials, it provides low performance and high electric resistance.
Cca
Since July 1st 2017, the materials used in construction have to be identified in compliance with the CPR (Construction Product Regulation) standard.
The Cca identifier refers to the reaction to fire Euroclass of the cable material, in this case a high-protection cable (low fire hazard) equipped with a sheath that prevents the flame from spreading
