For the first time, we show that 100G coherent digital CFP is efficient to address short-reach (<150 km), regional (<1000 km), and ultra long-haul (∼2000 km) transmission applications with half the cost, one third the power consumption and one quarter the size of common 100G WDM interfaces.
Thermal fluctuation plays an important role in magnetic recording system and it has to be seriously considered when designing recording media and hard disk drive (HDD) system. Unfortunately, it is impossible to perform several-year-lasting thermal stress tests to measure thermal stability during the design cycles of HDD products. Usually, the long term thermal stability was predicted by fitting the...
