Question 26 of 35 T e e s You're installing network wiring for a new Ethernet network at your company’s main office building. The project specifications call for Cat Se 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 closer inspection, it appears very similar to the Cat Se wiring. To finish the project, should you use the Cat 3 cabling as a substitute for the Cat Se cabling? No. The sheath surrounding Cat Se cabling is (o much thicker than the Cat 3 sheath, creating an extra layer of shielding that reduces crosstalk and supports higher data rates. No. Cat 5e cabling has more twists per inch @ than Cat 3 cabling, reducing crosstalk and supporting higher data rates. No. Cat Se cabling uses a thicker copper wire (O than Cat 3 cabling, enabling higher data transmission rates. Yes. You can use Cat 3 cabling as a substitute (O for Cat 5e cabling since they're electrically identical.
