IEC 61754-23:2005

Overview

IEC 61754-23:2005 is an international standard published by the International Electrotechnical Commission (IEC) that defines the interface dimensions for the Type LX.5 family of fibre optic connectors. As part 23 of the IEC 61754 series, this standard specifies precise mechanical and dimensional requirements to ensure interoperability and compatibility of LX.5 connector interfaces in fibre optic communication systems.

The standard plays a key role in guiding manufacturers, designers, and users of fibre optic components by establishing uniform connector interface criteria, enabling consistent performance and facilitating the global interchangeability of optical connectors within the LX.5 family.

Key Topics

• Connector Interface Dimensions: IEC 61754-23 details the exact dimensions of the physical interface for Type LX.5 connectors, including the ferrule end face and plug connector features, providing crucial guidance for design and manufacturing.

• Polish Types: The standard covers both Physical Contact (PC) and Angled Physical Contact (APC) polish varieties, specifying the respective dimensional tolerances critical to minimizing insertion loss and back-reflection.

• Simplex and Duplex Interfaces: It defines interfaces for both simplex and duplex plug connectors and adaptors, ensuring versatility in various fibre optic system configurations.

• Reference Planes and Gauges: The document includes reference planes and pin gauges for adaptors to verify compliance, support quality control, and aid accurate assembly.

• Ferrule Grades: IEC 61754-23 categorizes ferrule grades with associated dimensional classifications to clarify connector quality standards.
