Verkotukseen käytettäviä kaapeleita ja liittimiä on monenlaisia, mutta tällä hetkellä kenties yleisin on kategoria 6 (lyhyesti kat6 tai cat6) parikaapeli. Muita kaapeleita ovat mm. cat5, cat7 ja valokuitukaapelit. Verkkokaapeleissa tärkeintä on hyvä sähköinen (tai optinen) kontakti ja johtimien oikea järjestys.

There are various cable and connector types used in networking, but at the time the most common combination you'll run into are cat6 (short for category six) cables and connectors. Other common cabling types are cat5, cat7 and optical fibre cables. In network cabling, the most important concepts are good electrical (or with fibre, optical) contact and the correct placement order of the contacts in the connectors.

*Suorat kaapelit '''(straight through cable)''' ovat kaapeleita joissa molempien päiden johdinjärjestys on sama. Suorilla kaapeleilla kytketään erilaisia laitteita toisiinsa (esim. tietokone <> kytkin). Päät voi tehdä kummalla vain standardilla kunhan molemmat päät on tehty '''samalla''' standardilla.

*'''Straight through cables''' or straight cables are the most common cable type found. In straight cables the order of the contacts are the same in both ends of the cable. Straight cables are used to connect devices with different kind of networking hardware into each other (for example, a computer<>switch connection would use a straight cable). You can terminate the connectors with either cabling standard you like, but make sure you use the '''same''' standards on both ends.
  
  
−
*Ristikytkentäkaapelit '''(crossover cable)''' ovat kaapeleita joissa vihreitten johtimien ja oranssien johtimien järjestys on vaihdettu kaapelin päitten kesken, eli toinen pää tehty standardin A mukaan ja toinen standardin B mukaan. Ristikytkentäkaapeleilla kytketään samanlaisia laitteita toisiinsa (esim. kytkin <> kytkin).
+
*'''Crossover cables''' are cables where the green and orange contacts switch places with each other between the cable ends. In other words, one end of the cable is terminated as standard A and the other one according to standard B. Crossover cables are used to connect devices with similar kinds of networking hardware to each other (for example, a switch<>switch connection would be made with a crossover cable).
  
  
−
*'''Rollover'''-kaapeli on kaapeli jolla yleensä liitytään ciscon verkkolaitteiden konsoliporttiin. Kaapelin nimi on '''rollover''' koska johtimien järjestys päiden välillä on peilattu.
+
*'''Rollover cables''' are cables where the contact order is mirrored between the cable ends. Rollover cables are usually used to connect to Cisco networking hardware.

Overview

There are various cable and connector types used in networking, but at the time the most common combination you'll run into are cat6 (short for category six) cables and connectors. Other common cabling types are cat5, cat7 and optical fibre cables. In network cabling, the most important concepts are good electrical (or with fibre, optical) contact and the correct placement order of the contacts in the connectors.


Different types of network cables

Some common types of different networking cables are straight cables, crossover cables and rollover cables.

  • Straight through cables or straight cables are the most common cable type found. In straight cables the order of the contacts are the same in both ends of the cable. Straight cables are used to connect devices with different kind of networking hardware into each other (for example, a computer<>switch connection would use a straight cable). You can terminate the connectors with either cabling standard you like, but make sure you use the same standards on both ends.


  • Crossover cables are cables where the green and orange contacts switch places with each other between the cable ends. In other words, one end of the cable is terminated as standard A and the other one according to standard B. Crossover cables are used to connect devices with similar kinds of networking hardware to each other (for example, a switch<>switch connection would be made with a crossover cable).


  • Rollover cables are cables where the contact order is mirrored between the cable ends. Rollover cables are usually used to connect to Cisco networking hardware.


  • Remember, electricity does not care about the color of the wire!
