You are installing cat5 cabling in a large corporate campus. You have measured the distance from a network closet to a new annex building to be 90 meters. According to the cat 5 specification, is the use of a signal repeater necessary?
No, this is below the maximum distance of 200 meters
Yes, the max length is 75 meters
Yes, the max length is 50 meters per network segment
No, this is below the maximum distance of 100 meters
Category 5 cabling is rated for a maximum of 100 meters.
Category 5 cable (Cat 5) is a twisted pair cable for computer networks. Since 2001, the variant commonly in use is the Category 5e specification (Cat 5e). The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair up to 2.5GBASE-T but more commonly runs at 1000BASE-T (Gigabit Ethernet) speeds. Cat 5 is also used to carry other signals such as telephone and video.
This cable is commonly connected using punch-down blocks and modular connectors. Most Category 5 cables are unshielded, relying on the balanced line twisted pair design and differential signaling for noise rejection.
