How to reduce the input power of an optical module
Therefore, an optical attenuator is required to reduce the optical power. In addition, during signal transmission in a WDM system, the optical power of signals in each channel needs to be approximately the same to avoid transmission performance deterioration caused by uneven. Murata proposes a full range of Ultra BroadBand (UBB) Silicon capacitors of various sizes and operating voltages, all of them providing very low insertion losses up to 220 GHz, thanks to their specific design and construction, using semiconductor processes. This has driven development of the three following approaches, which combine or eliminate functions and reduce energy consumption by as much as 70 percent while delivering capacity up to 1. Measured in decibels (dB), loss degrades signal quality, limits distance, increases bit-error rate, and escalates infrastructure cost.
