What is BS EN 4533-003- Looming and installation practices of fibre optic systems about?
BS EN 4533-003 considers best practices during initial design and how the practices were chosen effect through life support of the installation. Looming and installation practices are critical aspects of any aircraft electrical/avionics installation. In order to provide a reliable and efficient system, it is important that the fibre optic installation is designed for reliability and maintainability.
BS EN 4533-003 provides technical advice and assistance to designers and engineers on the incorporation of fibre optic harnesses into an airframe, while, wherever possible, maintaining maximum compliance with current aircraft electrical harness procedures.
All topics that are related to the Installation of optical cables are addressed in EN 3197. These rules are applicable for fibre optic cables and connectors defined by EN specifications.

Why should you use BS EN 4533-003- Looming and installation practices of fibre optic systems?
It is widely accepted in the aerospace industry that photonic technology has significant advantages over conventional electrical hardware. These include massive signal bandwidth capacity, electrical safety, and immunity of passive fiber-optic components to the problems associated with electromagnetic interference (EMI).
Compared to the mature telecommunications applications, an aircraft fibre-optic system needs to operate in a hostile environment (e.g., temperature extremes, humidity, vibration, and contamination) and accommodate additional physical restrictions imposed by the airframe (e.g. harness attachments, tight bend radii requirements, and bulkhead connections).
BS EN 4533-003 is intended to give broad guidelines for both professionals and non-experts in the design, installation, and support of fiber-optic systems aboard aeroplanes. More specific sources of information are cited throughout the text as needed. BS EN 4533-003 gives information on System design considerations including the interconnects, maintainability strategy, splice, spare fibre, and replacements.
