1M ST to LC Duplex SM Patch Lead – Hybrid Fibre Connectivity with Precision
The 1 Metre ST to LC Duplex Single Mode Patch Lead from Attac is engineered for secure, high-speed, low-loss fibre connections in mission-critical applications. Featuring an ST connector on one end and an LC/UPC connector on the other, this hybrid duplex patch lead bridges legacy and modern systems in telecoms, FTTH, and data centre environments.
Secure Bayonet and Compact Snap-In Connectivity
The ST connector utilises a twist-lock bayonet mechanism, providing a robust and stable physical connection commonly used in legacy or test systems. On the opposite end, the LC/UPC connector offers a compact form factor with ultra-polished contact, supporting dense patch panels and modern networking equipment. Together, they deliver a seamless and secure interface between old and new infrastructure.

Built for Performance and Durability
Constructed using high-quality G657A or G652D single-mode fibre, this patch lead ensures low insertion loss (≤0.20dB) and high return loss (≥60dB). The duplex design enables simultaneous two-way communication, essential for full-duplex optical systems.
Safety and Installation Flexibility
The outer sheath is available in LSZH or PVC, making the cable suitable for a wide range of installation environments. LSZH is recommended for enclosed or public areas due to its flame-retardant, non-toxic properties, while PVC provides flexibility in standard installations. The 1-metre length is perfect for rack-to-rack or device-to-panel patching.

Frequently Asked Questions
What is the advantage of combining ST and LC connectors?
ST connectors offer secure bayonet locking for legacy systems, while LC connectors provide compact, high-density compatibility. A hybrid patch lead enables seamless connection between the two formats.
Is this patch lead suitable for long-distance single-mode transmission?
Yes. With low insertion loss and high return loss, it supports high-bandwidth, long-distance communication over single-mode fibre.
What’s the benefit of an LSZH jacket?
LSZH jackets reduce smoke and toxic emissions during a fire, making them ideal for enclosed spaces, public buildings, and safety-critical installations.
