We demonstrate transmission of a 200-Gb/s superchannel over 3-km single-mode optical fiber (SMF) targeting intra-data center interconnect applications using a novel single-section quantum-well passive-mode-locked laser that generates an optical frequency comb. The transmitted optical signal consists of 16 subcarriers filtered from the optical frequency comb of the laser and modulated with an advanced modulation format of Baudrate-pilot-aided quadrature phase-shift keying (QPSK) modulation that enables direct detection. Bit error rates below the forward error correction limit have been confirmed for all subcarriers, and the detailed noise characteristics of the passive-mode-locked laser have been investigated to support the understanding of the system performance.

Aim: To examine the reliability and construct validity of the Spanish adaptation of the Spirituality and Spiritual Care Rating Scale (SSCRS) within the nursing professionals' context., Design: Observational and descriptive cross-sectional study., Methods: The sample consisted of N = 325 nursing professionals from various healthcare settings, including hospitals, clinics and community healthcare centres. Following translation and cultural adaption of the SSCRS, the scale underwent psychometric assessment of its construct validity through exploratory and confirmatory factor analysis. Internal consistency analysis was also performed using a McDonald's omega. The reporting in this investigation adhered to the STROBE checklist., Results: The exploratory factor analysis (EFA) revealed a two-factor structure, with one factor closely aligning with one religiosity dimension and the other factor combining the spirituality, spiritual care and personalised care dimensions. The results of the confirmatory factor analysis did not provide an adequate fit to the data for both the two-factor solution found in the EFA and the four-factor solution proposed by McSherry, Draper, and Kendrick (2002). Even though the four-factor solution showed a slightly better fit than the two-factor solution, neither model achieved a satisfactory fit. The lack of formal education and confusion between religion and spirituality among healthcare professionals could have influenced the responses and interpretation of the results., Conclusion: The findings showed that the SSCRS-Sp demonstrated good internal consistency, indicating that the items in the scale are reliably measuring the targeted constructs. Further refinement and validation of the scale are needed to establish a robust factor structure in the target population., Relevance to Clinical Practice: The SSCRS-Sp can be used to assess the nurses' perceptions of spirituality and spiritual care. The availability of this tool represents a significant step towards greater integration of the spiritual dimension of care within a holistic nursing care framework in Spanish-speaking countries., Patient or Public Contribution: Nursing professionals responded to the research scale., (© 2024 The Author(s).
