Where to Use This Patch Lead

This 3M SC/APC single mode patch lead is designed for professional use in:

• FTTH (Fibre To The Home) and FTTx systems
• Data centres and enterprise IT rooms
• Telecommunications backbones and PON networks
• Optical Distribution Frames (ODFs)
• Mission-critical structured cabling environments

Durable and Standards-Compliant

Manufactured with G657A or G652D fibre, this patchcord is flame-retardant and environmentally safe thanks to its LSZH or PVC jacket. Designed to meet IEC and ITU optical standards, the SC/APC duplex configuration ensures exceptional precision and return loss control.

Installation Flexibility

Its 3 metre length offers enough slack for rack-to-rack or rack-to-ODF patching without excess clutter. The angled SC/APC connectors reduce signal reflection, making it ideal for applications sensitive to return loss such as PON and video overlay services.

Standards and Certification

All Attac fibre patch leads are factory-tested and compliant with IEC 61755-3-1 and ITU-T G.657A standards, ensuring quality and consistency in all environments.
