Home / Loss over one kilometer in multimode fiber optics
For multimode fiber, the loss is about 3 dB per km for 850 nm sources, 1 dB per km for 1300 nm. This chapter describes how to calculate the maximum allowable loss for a FICON®/FCP link that uses multimode components. It shows an example of a multimode FICON/FCP link and includes a completed work sheet that uses values based on the link example. Two different methods exist for splicing fibers: Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0. Fiber loss, also referred to as signal loss or fiber attenuation, stems from both intrinsic and extrinsic characteristics found in single-mode and multimode fibers.
