Applying data visualization for failure localization
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialData visualization is applied to BER measures in a bigdata repository. Bubble charts are produced to identify lightpaths with increasing BER and spectrum color maps are then used to identify the most likely degraded link -
Optimized differential detection-based optical carrier recovery for intradyne PSK receivers in udWDM-PON
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialWe present an optical carrier recovery based on differential detection that reduces required DSP hardware resources. Results show -55dBm sensitivity for BER=10-3 and high tolerance against fast LO frequency dithering, with ... -
