We can compare light transmission through an optical fiber with driving a car at maximum speed We want the road to be as straight as possible The probability that your car is still on the road at the other end of the turn decreases with increasing curvature of the turn Although there is a major difference The transmitted light is gradually lost when the curvature increases while your car is either on the road or not Therefore all the datasheets of optical fibers have a point called minimum bend radius or something similar This means that any bending of the fiber corresponding to a bend radius less than the given value will make the light leak out of the fiber A typical value is 20 mm to 40 mm Bellcore standard for single mode fibers You should also avoid putting any heavy items on top of the optical fibers because this will change the optical properties of the fiber and contribute to errors in the transmitted signal Unless the fiber is damaged it will regain its optical properties after a bend is straightened out or the items are removed the squeeze is released Network Electronics ASA Thoreya 3204 Sandefjord Norway Tel 47 33 48 99 99 Fax 47 33 48 99 98 E mail support network electronics com Web http www network electronics com Technical specifications are subject to be changed without notice innovator 28 FR CWDM Rev 1 6 2 Fiber optic Connector SCIPC connector protective cap ferrule T opti

8. FR CWDM Rev 1 6 3 Transmission budget A transmission budget is an important part of planning an optical link An optical link is the place where the signals are transmitted as light through optical fiber and optical components The total transmission budget is the difference between the laser output power and the receiver sensitivity Example A 0dBm laser and a 30dBm receiver gives a transmission budget of 30 dB Which means that the signal can be attenuated by 30 dB between the laser and the receiver while still being recoverable Patch panels splices optical filters and other optical components will add attenuation to the optical link An estimate of the attenuation in the optical filters in the flashlink CWDM system is found in chapter 1 It is not recommended to use the entire available budget one should have 3 dB margin to compensate for future degradation of the optical link More on transmission budgets can be found on our web site http www network electronics com Network Electronics ASA Thoreya 3204 Sandefjord Norway Tel 47 33 48 99 99 Fax 47 33 48 99 98 E mail support network electronics com Web http www network electronics com Technical specifications are subject to be changed without notice innovator 31 FR CWDM Rev 1 7T Application notes 7 1 ADM nodes Add Drop Multiplex nodes can be built by combining a digital video router with the flashlink CWDM system An example of an
