Descrição
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.
O Faces de extremidade com polimento UPC ensure tight physical contact, keeping reflections low and signals clean for both data transmission and optical monitoring.

Desempenho no mundo real
At 850 nm, 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 perda de inserção e perda de retorno, ensuring stable performance even after hundreds of reconnections.
The LSZH jacket option also supports modern fire-safety requirements in indoor installations.
Perguntas e respostas profissionais
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?
Sim. 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.
P4: O polimento do UPC afeta a qualidade do sinal?
Yes. UPC reduces surface reflections and keeps return loss at ≥30 dB, improving transmission stability and measurement accuracy.
