IEC 61754-36:2025

Overview

IEC 61754-36:2025 is an international standard published by the International Electrotechnical Commission (IEC) that defines the mechanical interface dimensions for the type SAC family of fibre optic connectors. This standard ensures interoperability and consistency for fibre optic interconnecting devices and passive components, specifically focusing on the SAC connector family. The SAC connectors use miniature duplex plug/adaptor/plug configurations designed for high-performance fibre optic communication systems.

The document provides comprehensive mechanical specifications, including dimensional, interface, and alignment characteristics for connectors, adaptors, and receptacles within the SAC family. It covers various interface types such as duplex and quadruplex connectors and includes physical contact (PC) and angled physical contact (APC) variants.
