1M SC to SC Duplex SM Patch Lead – Reliable Connectivity for Single-Mode Fibre Networks
The 1M SC to SC Duplex SM Patch Lead from Attac is designed for high-performance networking across long-distance single-mode fibre systems. With SC/UPC connectors at both ends and a duplex configuration for bidirectional communication, this patch lead is ideal for backbone telecom systems, FTTH deployments, and structured cabling in enterprise or data centre environments.
High-Speed Transmission with Low Loss
Built using G657A or G652D single-mode fibre, this cable supports long-range, high-bandwidth communication with minimal signal attenuation. Each end is fitted with precision-polished SC/UPC connectors that ensure insertion loss ≤0.20dB and return loss ≥60dB for efficient and reliable data transfer.

Safe and Structured Installation
The patch lead is available with a LSZH jacket for use in public buildings, enclosed spaces, and high-density racks. LSZH materials reduce toxic emissions and smoke in the event of fire, making them suitable for modern networking environments with strict safety requirements.
Factory-Tested for Long-Term Reliability
Each patch lead is individually tested for optical performance, ensuring high-quality connectivity across telecom, enterprise, and data infrastructure. The duplex layout allows for simultaneous send/receive channels while keeping cabling neat and manageable—especially in rack or ODF scenarios.

Frequently Asked Questions
What is the difference between SC/UPC and SC/APC?
SC/UPC has a flat polish and is ideal for digital signals requiring low insertion loss. SC/APC has an angled polish that reduces back reflection, typically used in analogue systems.
Is this patch lead suitable for indoor telecom cabinets?
Yes. The LSZH jacket makes it flame-safe for use in enclosed or high-density environments like server racks and telecom rooms.
What is the advantage of a duplex configuration?
A duplex patch lead has two fibres—one for transmitting and one for receiving—making it ideal for two-way communication in fibre networks.
