BS EN 61754-31 is a safety standard on fibre optic interconnecting devices and passive components.
BS EN 61754-31 defines the standard connector interface dimensions for the two-way and four-way type N-FO family of connectors.
The plugs and sockets given in BS EN 61754-31 have ferrules with a spherically polished end face, which realise physical contact (PC). The dimensional requirements apply to the finished ferrule after all polishing procedures have been completed.
BS EN 61754-31 on fibre optic connector interfaces is relevant to:
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with BS EN 61754-31 may involve the use of a patent concerning IEC 61754-31.
BS EN 61754-31 is about the type N-FO connector family. The N-FO connector family comprises a two way and four-way circular plug connector and socket set. The plug connector in each case includes a spring-loaded threaded coupling nut and the plug shell features a single keyway that is used to orient it with a key in the socket with which it is being mated. The 1,25 mm non-angle polished ferrules used within the connectors are aligned using resilient sleeves housed within the plug. A two-way system consists of two spring-loaded ferrules within each connector body. The pitch between the two fibre centres is nominally 3,0 mm. A four-way system consists of four spring-loaded ferrules in a row within each connector body. The pitch between any two adjacent fibre centres is nominally 2,50 mm.
Overall, BS EN 61754-31 is useful as it assists with the fibre optic connector interfaces for the type N-FO connector family which can be helpful for your business.
