When wanting to make a distribution network without special requirements in terms of performance, but without giving up a high quality product such as those made by us, and with a careful eye on the financial side as well, you can turn your attention to our Cat. 5e.
In the range, in addition to the above mentioned LAN540 and LAN541 that represent the basic models UTP and FTP, respectively, with PVC sheathing, which is flexible and suitable for the vast majority of networks, there are also LSZH, PE and double-sheathed versions, and a version in LSZH 2X, which gives the possibility to "pull" two cables at the same time and thus makes installation easier.
Cat. 5e cables are used in structured cabling for computer networks and for Ethernet networks over twisted pairs. They are suitable for transmissions up to 100 MHz in sections up to 100 m in length; specifications on Cat. 5e are defined by European standards EN50288-3-1 for UTP cables, EN50288-2-1 for FTP, and American standards ANSI/TIA/EIA-568-A.
They support transmissions over 10BASE-T, 100BASE-TX (Fast Ethernet) and 1000BASE-T (Gigabit Ethernet) networks. In this case, Ethernet connections 10BASE-T and 100BASE-TX require two pairs of wires. 1000BASE-T Ethernet connections require four pairs of wires.
It should be remembered that since these are copper cables, through the use of Power over Ethernet (PoE), power can be transferred over the cable in addition to data.
Cat 5 is also used to carry other signals such as telephony and video (also widely used in video surveillance). In some cases, multiple signals can be carried on a single cable, e.g., two conventional telephone lines and a 100BASE-TX network in a single cable.

Special design features of inexpensive LAN cables
The entire range consists solely of cables with red copper conductors, drawn by us.The highest performing LAN cables:
The Class FA channel and the Cat. 7A cable were introduced to support transmissions up to 1000 MHz over 10Gigabit Ethernet networks for lengths of up to 100 m.
Cat 7A is suitable for multiple applications, including transmission at 40 Gigabit Ethernet up to 50 m, 100 Gigabit Ethernet up to 15 m, CATV (bandwidth up to 862 MHz).
CAVEL's Cat 7 cable offering consists of three models:
Cat 7A is suitable for multiple applications, including transmission at 40 Gigabit Ethernet up to 50 m, 100 Gigabit Ethernet up to 15 m, CATV (bandwidth up to 862 MHz).
CAVEL's Cat 7 cable offering consists of three models:
- LAN7A1000 (frequency up to 1000 MHz)
- LAN7A1200 (frequency up to 1200 MHz)
- LAN7A1500 (frequency up to 1500 MHz)
Special design features of the highest performing LAN cables
To obtain such high-performance cables, every stage of production is meticulous, from the internal drawing of the conductor, to the extrusion of the insulation, which for our Cat. 7 cables is gas-expanded PE with skin-foam-skin technology (as in coaxials, unlike in cables of lower Ethernet categories). Furthermore, these are PIMF cables equipped with double S/FTP shielding, i.e., a braid that wraps around the cable as a whole, and foils that wrap around the individual pairs.We recommend:
These LAN cables are LAN Cat 6 U/UTP and Cat 6 F/UTP and are cables designed to handle links up to 250 MHz.
In data transmission, these LAN cables support the following network protocols:
And in fact, with this type of cable, it becomes more important both to use quality connectors approved for the specific category, and to ensure that the connectorization is properly made, and that the cable is handled with due care, in order to avoid pulling in excess of 100 N and excessive twisting and bending of the bend radius.
In Cat. 6 as well, in addition to the models mentioned above, our range includes PVC-sheathed LAN cables, sufficient in many applications and slightly cheaper, as well as PE or even double-sheathed cables for more extreme conditions.
In data transmission, these LAN cables support the following network protocols:
- 10BASE-T;
- 100BASE-TX (Fast Ethernet);
- 1000BASE-T/1000BASE-TX (Gigabit Ethernet).
- 10GBASE-T (10Gigabit Ethernet), but in that case, in an Alien Crosstalk environment favorable up to 55 meters, dropping to 33 m in a hostile environment (e.g., where numerous cables are bundled together).
Special design features of recommended LAN cables
Compared to cables of lower categories, these feature a separator between the 4 pairs of twisted conductors. This allows for higher performance in crosstalk and noise values, as it prevents the pairs from assuming positions that compromise and degrade the signal.And in fact, with this type of cable, it becomes more important both to use quality connectors approved for the specific category, and to ensure that the connectorization is properly made, and that the cable is handled with due care, in order to avoid pulling in excess of 100 N and excessive twisting and bending of the bend radius.

All LAN cables sold by Cavel are manufactured in our factory in Gropello Cairoli (PV), just outside Milan according to ISO 9001:2015 quality standards and are guaranteed for 15 years from their purchase
Here is a brief summary to see the main parameters for evaluating a LAN cable.
In addition to attenuation, the electrical values to look out for are: crosstalk (or NEXT), ACR and SRL.
In addition to attenuation, the electrical values to look out for are: crosstalk (or NEXT), ACR and SRL.
Attenuation, expressed in dB and in reference to 100 m of cable, represents the reduction of the signal over that section.
In addition to length, attenuation is directly proportional to the frequencies of the transmitted signal. There are other parameters that affect it: temperature, and degradation of the cable over time.
In addition to length, attenuation is directly proportional to the frequencies of the transmitted signal. There are other parameters that affect it: temperature, and degradation of the cable over time.
Crosstalk (or NEXT: Near-End Crosstalk), which is also measured in dB, manifests as unwanted electromagnetic coupling when two conductors are very close together; in LAN, it measures the coupling between a pair of conductors and adjacent ones. The coupling generates a disturbance that results in signal degradation).
The following can adversely affect this parameter: poor quality of the twisted pair due to the use of poor materials; lack of consistency in the twist pitch; the use of poor quality sockets or plugs; even the cable header on a plug with too much untwisted braid.

ACR (Attenuation-to-Crosstalk Ratio), again expressed in dB, is a parameter that is measured in the certification of a network, and represents the ratio of attenuation to NEXT in a twisted pair, and it depicts the overall performance of a cable, as it can be used to define its bandwidth.
The cable is tested at higher and higher frequencies, and as long as the values remain high, the cable is suitable for that particular frequency. International standards indicate specific ACR values for different categories of cables;

SRL (Structural Return Loss) is always measured in dB. It is another parameter for evaluating the cable's construction quality as it indicates the effects caused by incorrect values in the characteristic impedance, which, let us note, for LAN cables and Ethernet networks is 100 Ohms.
