Optical fiber connection navigation system using visible light communication in central office
An optimized optical-fiber-connection system for central offices is described. This system employs visible-light communication to reduce costs while maintaining the functions and usability of an earlier system. Little skill is needed to realize optical-fiber connection.
Novel Optical-Fiber Network Management System in Central Office Using RFID and LED Navigation Technologies
Optical IP services such as FTTH have been growing rapidly, leading to an urgent need to manage the optical fiber network from the central office. We have developed an optical-fiber distribution facility called an IDM. However, the changing FTTH environment means we need further efficiency and cost-effectiveness for network construction and operation work. This paper proposes a novel optical-fiber network management system for the IDM that realizes reducing working time, less skilled work and eliminating human error. This system consists of two technologies with control software, namely optical distribution identification technology using RFID, and automatic navigation technology using an LED and DB. In this paper, we describe optimized work flows for installation and removal work. Moreover, we achieved a reduction of up to 48 % in working time with less skilled workers and accurate DB management by using our proposed system.
Pedagogy of the “Not”: Negation, Exodus, and Postdigital Temporal Regimes
Postdigital capitalist time is an incessant acceleration that acts to homogenize time and wed us to the present, to which we have to constantly catch up. While the impulse of this is no doubt economic (the realization of value), it is crucially undergirded by a pedagogical logic wherein we have to perpetually learn and re-learn the latest apps, social media configurations, operating systems, and so on. Political strategies of resistance thus need to be bolstered by an alternative mode of educational life, and I propose a pedagogy of the “not” as one possibility. Such a pedagogy is an act of suspension that sustains a detachment from the present, clearing out oppositions and thereby exposing us to a radical indeterminacy and potentiality that is always untimely. Suspension is the praxis of negation, which means that negation operates by keeping sense indeterminate to meaning and signification. Rather than suppressing, disavowing, or annihilating the stated content, negation retains even that which is negated. While this would appear as a form of exopedagogy, which withdraws from the dialectic of the private/public, I instead argue that it redefines the terms of any dialectic, redefining the very categories exopedagogy withdraws from. Before concluding, I spend some time with Sandy Grande’s important critiques of Eurocentrism and progress in Western critical education, demonstrating how negation as suspension circumvents these errors through its accommodation of—or, better, insistence on—variegated temporalities and forms of life.
