Our brand ROLINE

A) ROLINE USB cable

• The data cores correspond to AWG28.
• The current wires correspond to AWG24 (the lower the AWG number, the higher the cross-section).
• The material used is solid copper.
• The shield consists of a foil screen and a tin-plated copper braided screen with a coverage of more than 65 %.

B) Cheap USB cable

• The data cores correspond to AWG 30 and worse.
• The current wires correspond to AWG 30 and worse.
• The material used is CCA = massival aluminum coated with a thin copper layer.
• The shielding consists of a foil screen and a braided screen made of an alloy with a coverage of less than 30 %, or completely without shielding.

Effects:

• Data loss due to poor electrical properties of the data line pair.
• From a short distance, the power supply of the connected devices is no longer ensured by an ohmic resistance of the pair of current pairs.
• High interferences due to poor shielding characteristics lead to data loss and transmission errors.

A) ROLINE data cable

• The data cores correspond to AWG28.
• The material used is solid copper, the screen consists of a foil screen with wire and, depending on the type, a tinned copper braided screen as well as a shielded plug housing, the contacts of the connectors are gold-plated.

B) Cheap data cables

• The data cores correspond to AWG 30 and worse.
• The material used is CCA = massivuminium coated with a thin copper layer, or CCS = solid steel coated with a thin copper layer.
• The shield consists of a foil screen without wire, braid shield is missing and the connector housings are not shielded.
• The contacts of the connectors are not gold-plated but at best "gold-plated" with gold.

Effects:

• Data loss due to poor electrical properties of the data cores.
• Data transmission is no longer possible from a short distance, since the impairment of the data signal becomes too strong due to an ohmic resistance of the cable.
• High interferences due to poor shielding characteristics lead to data loss and transmission errors.
• After a few plug-in cycles, a clean contacting is no longer possible, leading to sporadic interruptions or total failure.

A) ROLINE SVGA cable

• The RGB cores are coaxial cables with 75 Ohm.
• The data arrays correspond to AWG28 and there are 7 or 9 depending on the version.
• The material used is solid copper.
• The shielding consists of a foil screen with a wire and a tin-plated copper braided screen as well as a shielded plug housing.
• The contacts of the connectors are gold-plated.

B) Cheap SVGA cables

• No coaxial lines are used for the RGB signals.
• The data cores correspond to AWG 30 and worse; There is max. 4.
• The material used is CCS = solid steel coated with a thin copper layer.
• The shield consists of a foil screen without wire, braid shield is missing and the connector housings are not shielded.
• The contacts of the connectors are not gold-plated but at best "gold-plated" with gold.

Effects:

• Very poor image representation even at short distances due to poor electrical characteristics of the data cores and non-existing RGB coaxial arrays.
• Even a short distance no synchronization is possible, since the impairment due to too great an ohmic resistance of the cable becomes too strong.
• High noise immunity due to poor shielding characteristics lead to disturbances in the image transmission.
• After a few plug-in cycles, a clean contacting is no longer possible, leading to sporadic interruptions or total failure.

A) ROLINE HDMI High Speed Cable

• 5 individually shielded twisted pair pairs.
• 4 data wires correspond to AWG 30 to 24 depending on the length of the cable.
• The material used is solid copper.
• The shield consists of a foil screen and a tin-plated copper braided screen as well as a shielded plug housing.
• The contacts of the connectors are gold-plated.

B) Cheap HDMI High Speed Cable

• Twisted pair pairs are not used.
• The data cores correspond to AWG 30 and worse.
• The material used is CCS = solid steel coated with a thin copper layer.
• The shielding for the individual twisted pair pairs is missing.
• The overall screen consists of a screen and a braid screen with very little coverage, or this is missing completely.
• The contacts of the connectors are not gold-plated but at best "gold-plated" with gold.

Effects:

• No transmission of images is possible even at short distances due to poor electrical properties of the data cores.
• High noise immunity due to poor shielding characteristics lead to disturbances in the image transmission.
• After a few plug-in cycles, no clean contact is possible, which leads to sporadic interruptions or total failure.

A) ROLINE patch cable

• The cables were tested at the GHMT in Germany and meet the Cat.6 standard.
• The material used is solid copper.
• The RJ45 connectors are equipped with contacts with 50µm gold coating.

B) Cheap patch cables

• The cables do not meet any standards and are not tested.
• The material used is CCA = massival aluminum coated with a thin copper layer.
• The RJ45 connectors are equipped with contacts with max. 3µm gold coating or are merely "breathed".

Effects:

• The speeds of 100 MBit / s (Cat.5e) or 250 Mbps (Cat.6) cannot be reached.
• The inflexible material leads to interruptions and data loss after repeated bending.
• After a few plug-in cycles, a clean contacting is no longer possible, leading to sporadic interruptions or total failure.

A) ROLINE power supply cable

• The cores correspond to a cross-section of 0.75 mm² = standard dimension up to 2 m length.
• The material used is solid copper.
• The cables meet the requirements of the standards regarding device safety.

B) Cheap power supply cables

• The cores correspond to a cross-section of approx. 0.1 - 0.2 mm² up to 2 m length.
• The cables do not meet the requirements of the standards regarding device safety, as these cables are approved up to 10A, but the device safety for max. 1A.

Effects:

• The insulation melts and threatens fire due to overheating of the cable as soon as the cable is used with powerful devices (more than 1A power consumption).

A decisive criteria for the quality of cables are the nominal wire cross-sections of the individual twisted strands, which ultimately determine the overall cable thickness. The cable will only be approved by the quality control when this critical requirement is verifiably fulfilled.
