Document Summary
Suggested solution to assignment 4: briefly explain the advantages and disadvantages of the following transmission media choices: utp, stp, and fiber optic cables. Very cost effective compared to stp and fiber cables. Cross talk between various pairs within a cable. Electromagnetic interference(emi) due to radio waves and other sources. Tapping is extremely difficult and can be detected easily. Maximum segment length is of order of few kilometers. Joining optic fiber cables is difficult than joining copper cables as splicing is: list and briefly describe the 6 sub-systems of structured cabling in commercial buildings. Entrance facility: provides the point at which outside cabling interfaces with the intrabuilding backbone cabling. The physical requirements of the network interface are defined in the eia/tia-569 standard. Equipment room: the room house racks of equipments of higher complexity than tc. The design aspects of the equipment room are specified in the eia/tia 569 standard.
