BS EN 61300-3-42 is a part of an international multi-series standard that covers fibre optic interconnecting devices and passive components.
BS EN 61300-3-42 describes the method to measure the attenuation of single-mode adaptors with resilient sleeves and the attenuation of resilient sleeves.
The reference method for measuring attenuation is with an optical power meter. The measured attenuation is a result of the lateral offset between the fibre cores of the used connectors and the interaction between sleeve geometry and ferrule outer diameter.
BS EN 61300-3-42 on Fibre optic interconnecting devices and passive components is relevant to:
Attenuation is intended to give a value for the decrease of useful power, expressed in decibels, resulting from the insertion of a device under test (DUT), within a length of optical fibre cable. The DUT may have more than two optical ports (multiple adaptors).
BS EN 61300-3-42 describes the DUT's having two ports, as an attenuation measurement is made across only two ports. It provides you with the technicalities for examining and measuring the attenuation of single-mode alignment sleeves and or adaptors with resilient alignment sleeves. BS EN 61300-3-42 also lays out the precautionary measures that should be considered while measuring attenuation to assess the risks and mitigate them to avoid any sorts of failures or damages.
Overall, BS EN 61300-3-42 is useful as it assists you with the measurement procedures and attenuation of single-mode alignment sleeves and or adaptors for fibre optic interconnecting devices and passive components.
