Açıklama
This hybrid connector design allows older ST-terminated links to integrate cleanly into more structured SC distribution systems.
Designed for Mixed-Connector Environments
ST connectors are widely used in older fiber outlets and field installations, while SC connectors dominate in fiber panels and equipment racks. This patch cord acts as a practical bridge between the two—without adapters that introduce extra loss or instability.
Bu UPC cilalı uç yüzeyler ensure tight physical contact, keeping reflections low and signals clean for both data transmission and optical monitoring.

Profesyonel Soru-Cevap
Q1: Why are ST connectors still used in many sites?
ST connectors are rugged, easy to terminate, and highly tolerant to dust and vibration, which is why they remain common in older buildings and industrial networks.
Q2: Can this cable connect to modern switches?
Evet. SC end connects directly to modern fiber panels or switch ports that use SC adapters.
Q3: Is 62.5/125 fiber obsolete?
No. While it does not support high-speed 10G links, it remains widely used for 1G, Fast Ethernet, and CCTV fiber networks.
S4: UPC parlatma sinyal kalitesini etkiler mi?
Yes. UPC reduces surface reflections and keeps return loss at ≥30 dB, improving transmission stability and measurement accuracy.
