What is BS EN IEC 61754‑35 about?
BS EN IEC 61754 is a series on fibre optic interconnecting devices and passive components. BS EN IEC 61754‑35 defines the standard connector interface dimensions for the LSHE family of connectors with up to four termini. This connector family is targeting deployment under harsh environmental conditions.
BS EN IEC 61754‑35 specifies the mechanical connection between the plug connector and the socket which is ensured by a push-pull mechanism.
Who is BS EN IEC 61754‑35 for?
BS EN IEC 61754‑35 on fibre optic interconnecting devices is useful for:
- Fibre optic component manufacturers
- Design engineers
- Interconnecting device manufacturers
- Research and development facilities
Why should you use BS EN IEC 61754‑35?
Fibre optic interconnecting devices and passive components transmit information from one place to another by sending pulses of infrared light through fibre. The connectors discussed in BS EN IEC 61754‑35 are intended to be used outdoors, in industrial and, more generally, in harsh environments. It is therefore designed to survive under harsh conditions.
Type LSHE connector comprises a plug connector and a socket, each one containing an insert with up to four termini. Each terminus hosts a 2,5 mm (nominal) ferrule, which may be physical contact (PC) or angled PC (APC) polished.
The ferrules as discussed in BS EN IEC 61754‑35 are aligned through resilient sleeves housed in an adaptor that may be fixed either on the plug side or on the socket side (hermaphrodite connection system). Each terminus may support any type of fibre (SM, MM or other) provided the termini facing each other in the connection contain compatible fibres.
The interconnecting devices mentioned in the BS EN IEC 61754‑35 are ensured by a push-pull mechanism, that states that these connectors can be easily plugged and unplugged. Type LSHE connectors are designed to survive under harsh environmental conditions without causing any kind of damage to the transmission line.
