What is BS EN 61753-057-2 - Fibre optic interconnecting devices and passive components about?
BS EN 61753 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components is a fibre optic telecommunications technology for delivering broadband network access to end customers. BS EN 61753-057-2 contains the minimum initial test and measurement requirements and severities that a fibre optical fuse satisfies in order to be categorised as meeting the requirements of a single-mode fibre plug-receptacle style optical fuse used in controlled environments. Optical performance specified in this document relate to plug-receptacle style configuration fuses only.

Why should you use BS EN 61753-057-2 - Fibre optic interconnecting devices and passive components?
The optical fuse is a passive device, designed to protect equipment and fibre cables from damage due to optical overpowering, spikes and surges. The optical fuse produces a controlled, permanent, signal blocking at a predetermined power threshold in an optical fibre transmission line. The optical fuse is wavelength-independent over its entire specified spectral range. IEC 60869-1 contains the generic information of the optical fuse. The optical fuse has a maximum allowed power input Pin max that is allowed. Beyond this power, it is dysfunctional and can let light through. Numerical values for Pin max are given in BS EN 61753-057-2.
BS EN 61753-057-2 describes the testing of optical fuse functionality and measurement of its parameters. Testing of the following parameters, which do not appear in regular IEC standards is described as power threshold, blocking attenuation at threshold and response time. The fuse is a safety device and only destructive testing can test its functionality; it is not functional anymore after exposure to powers over the threshold. The actual test requires high power and needs a dedicated test set up, designed for these measurements. An example of a test carried out on an optical fuse will be followed according to BS EN 61753-057-2, where the optical fuse parameters are power threshold (each fuse in the batch), blocking attenuation at threshold and response time. Using BS EN 61753-057-2 you can understand the minimum initial test and measurement requirements and severities that a fibre optical fuse satisfies in order to be categorised as meeting the requirements of a single-mode fibre plug receptacle style optical fuse used in controlled environments.
