1. Clarify, whether a fiber optic cable can be called as a transmission line? Also justify the conditions that are required for a transmission line. 2. Compare STP and UTP with relevant diagram. Suggest, which is the best in your opinion. 3. For the given diagram the Full angle of 270, calculate the "Figure of merit" for the water medium. Pulangle - 270 4. For a four pair UTP cable if the value of Vin= 5V, Vout= 2V, VNEXT1= 4 mv, VFEXT1= 1.5V, then find the value of FEXT1, NEXT1 and ACR in decibels and also assume the reasonable value of NEXT2, NEXT3 to find the value of PSNEXT. 5. Describe the operation of temperature sensitive detector device with a neat diagram
