No. Cat 5e cabling has more twists per inch than Cat 3 cabling, reducing cross-talk and supporting higher data rates.While Cat 3 and Cat 5e cabling may appear similar physically, they are electrically different. Cat 5e cabling is twisted much tighter than Cat 3 cabling. This reduces cross talk and enables Cat 5e wiring to support much faster data transmission rates.
  • You are installing networking wiring for a new Ethernet network at your company's main office building. The project specifications call for Cat 5e UTP network cabling and RJ45 wall jacks. Near the end of the project, you run out of wire before the last few runs are complete. You have a spool of Cat 3 network cable in storage. Upon investigation, it appears very similar to Cat 5e wiring.Should you use Cat 3 cabling as a substitute for Cat 5e cabling to finish the project?
  • You are adding new wires in your building for some new offices. The building has a false ceiling that holds the lights and provides an air path for heating and air conditioning. You would like to run your Ethernet cables in this area.Which type of cable must you use?
  • When would you typically use an RJ11 connector?
  • Which of the following connector types would you most likely use to connect to a T1 WAN service?
When connecting a phone to a phone lineAn RJ11 connector is used for connecting analog telephones to the telephone jacks.Cat 3, Cat 5, and higher twisted pair cables use RJ45 connectors. Coaxial cables use F-type or BNC connectors. Fiber optic cables use a variety of connectors (ST, SC, LC, MT-RJ, FC).
  • When would you typically use an RJ11 connector?
  • Which of the following connector types would you most likely use to connect to a T1 WAN service?
  • Why might you use an RJ11 connector?
  • Which of the following connectors is used with Ethernet 100BaseT networks?
You want to connect your computer to the internet with a DSL modem.RJ11 connectors are typically used for telephones and modems.
  • Which of the following connectors is used with Ethernet 100BaseT networks?
  • Which of the following cable types often includes a solid plastic core that keeps the twisted pairs separated?
  • Why might you use an RJ11 connector?
  • When would you typically use an RJ11 connector?
RJ45RJ45 connectors are used with Ethernet 100BaseT networks.RJ11 connectors are used with phone, dial-up internet, and DSL modem connections. BNC connectors are used with coaxial cable. ST connectors are used with fiber optic cable.

  • Which of the following cable types often includes a solid plastic core that keeps the twisted pairs separated?
  • When would you typically use an RJ11 connector?
Plenum rated cablePlenum rated cable is fire resistant and non-toxic. You must use plenum rated cable to wire in air spaces used by heating and air conditioning systems. You cannot use PVC jacketed cable to wire above ceilings because it is toxic when burned.Cat 5e cables provide better EMI protection than Cat 5 cables, and Cat 6a cables are an improvement over Cat 6 specifications, but neither of these qualities are a requirement for use in a ceiling area. If the area has a lot of EMI, you might consider using STP or fiber optic cables, but this is not a requirement for wires were in a ceiling area. Typically, you can avoid EMI sources by re-routing cables.
