الوصف
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.

الأداء في العالم الحقيقي
في 850 نانومتر, OM1 62.5/125 µm multimode fiber supports:
-
1G Ethernet up to 275 meters
-
Fast Ethernet up to 2 km
This makes the ST–SC duplex jumper well suited for:
-
Campus and office networks
-
Fiber CCTV and security systems
-
Industrial monitoring
-
Telecom and building distribution frames
Precision You Can Depend On
Every patch cord is factory assembled with ceramic ferrules, UPC polishing, and automated interferometer inspection. Both channels are tested for فقدان الإدراج وفقدان الإرجاع, ensuring stable performance even after hundreds of reconnections.
كما يدعم خيار السترة LSZH LSZH أيضًا متطلبات السلامة من الحرائق الحديثة in indoor installations.
أسئلة وأجوبة احترافية
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?
نعم. نهاية SC 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.
س4: هل يؤثر صقل UPC على جودة الإشارة؟
Yes. UPC reduces surface reflections and keeps return loss at ≥30 dB, improving transmission stability and measurement accuracy.
