2M LC/APC Duplex SM Patch Lead – Ultra-Low Loss Fibre Performance
The 2 Metre LC/APC to LC/APC Duplex Single Mode Patch Lead from Attac is a premium-grade optical cable engineered for applications that demand extremely low signal loss and high return loss. Designed with precision LC/APC connectors and high-quality single-mode fibre, this patch lead ensures clean and efficient transmission across critical FTTH, telecom, and data centre networks.
Angled Polish for High Return Loss
Fitted with LC/APC connectors on both ends, this patch lead features 8° angled polishes that reduce back reflection—making it ideal for applications sensitive to signal integrity such as long-haul communication, WDM systems, and high-precision optical equipment. The typical return loss rating of ≥60dB ensures stable optical paths even in the most demanding deployments.

Safe and Flexible Installation
This patch lead comes with a LSZH or PVC jacket, offering safety compliance and flexibility. LSZH is especially suitable for use in enclosed spaces or public infrastructure, as it minimises smoke and toxic emissions during fire. The 2-metre length allows for slightly longer routing within racks, cabinets, or between devices without excess slack.
Reliable Optical Performance
Each Attac patch lead is factory-tested to strict tolerances, delivering insertion loss ≤0.20dB and return loss ≥60dB. The duplex configuration supports bi-directional transmission, making it a robust solution for two-way links across structured cabling networks.

Frequently Asked Questions
What is the benefit of LC/APC over LC/UPC connectors?
LC/APC connectors use angled polish to reduce back reflection, making them ideal for analogue and high-precision applications, while LC/UPC is better suited for digital systems requiring low insertion loss but with less emphasis on return loss.
Is this patch lead suitable for enclosed environments?
Yes. The LSZH jacket is designed for safety in enclosed or public spaces by reducing toxic smoke and halogen gas emissions in case of fire.
Can this be used for GPON or XGS-PON networks?
Absolutely. LC/APC duplex patch leads are widely used in GPON and XGS-PON systems due to their low reflection and high stability over long distances.
