a) A GPON optical fiber network is used to provide data/voiceservices to 23 subscribers, 16 of which are placed 57 Km from theOptical Line Terminal 57. The splitter serving the 16 subscribersis located 55 Km from the Optical Line Terminal. Seven subscribersare also located 30 Km from the Optical Line Terminal and are alsoserved by a splitter placed 2Km from the subscribers. Given that,three new clients want the same service 2Km from any of the 16subscribers.
i. Design the network indicating all the nodes.
ii. Further, explain the function of each network devices in theGPON you designed.
b) A fibre link for transmission of life stream to a client 59Km from the source. The link employs 1:2 and 1:16 splitters. Giventhat there is a splice every 17 Km from the Optical Line Terminaltowards the client in the network with splice loss of – 1dB,connector loss – 6dB, operating wavelength of 1550 nm and inputpower 6 dBm. For the link to work the received power range is – 25dBm to – 21.65 dBm. Evaluate downstream-received power and commenton your answer.
c) What type of optical fiber cable is used to establish thelink in question 6b? Explain the reason or reasons for youranswer.
