  1. power budget analysis for Fiber optics link part 2 Prof. Bhagyashri Thorat Assistant Professor Department of Electronics & Telecommunication Hope Foundation’s International Institute of Information Technology Hope Foundation’s International Institute of Information Technology, I²IT, P-14 Rajiv Gandhi Infotech Park, Hinjawadi, Pune - 411 057 Tel - +91 20 22933441 / 2 / 3 | Website - www.isquareit.edu.in ; Email - info@isquareit.edu.in

  2. Optical power loss model A typical optical power loss model for a point- to- point link considered • one transmitter, • one receiver • two connectors & splices as shown in figure Hope Foundation’s International Institute of Information Technology, I²IT, P-14 Rajiv Gandhi Infotech Park, Hinjawadi, Pune - 411 057 Tel - +91 20 22933441 / 2 / 3 | Website - www.isquareit.edu.in ; Email - info@isquareit.edu.in

  4. The total optical power received at photodetector is equal to losses occuring in fiber, connetor , splices & loss of light coupled into fiber from transmitter. • The loss budget is nothing but summation of above losses mention. Each of these loss elements is expressed in decibels (dB) as, • Where, Hope Foundation’s International Institute of Information Technology, I²IT, P-14 Rajiv Gandhi Infotech Park, Hinjawadi, Pune - 411 057 Tel - +91 20 22933441 / 2 / 3 | Website - www.isquareit.edu.in ; Email - info@isquareit.edu.in

  5. The total link loss budget is equal to differenence between optical power emering from the end of a fiber flylead attached to the light source and receiver sensitivity .

  6. Link power margin or system margin • Link Power analysis is capable to provide analysis which gives compnent aging, temperature fluctuations and losses arising from components that are going to add in future. • This addition in link budget is called link power margin, normally its between range 3 to 6 dB.
