3M NBN Fibre Optic Cable SCA-SCA OS2 9/125 Singlemode Simplex

Introduction

This singlemode simplex fibre patch cable with SC-APC (SCA) male connectors on both ends, manufactured with OS2 9/125 µm singlemode optical fibre. Designed for indoor premises and NBN connections (ONT → router, patch panel → equipment, FTTP patching), this patch cord delivers low loss, high return-loss performance suitable for broadband, FTTP and other singlemode telecom/data applications. The cable is supplied with a White jacket (OS2 standard), LSZH jacket for safe indoor use, and factory-polished APC end-faces for excellent back-reflection performance.
