Description
Why FC-to-ST on OM3 Fiber?
FC connectors provide threaded, vibration-resistant locking, making them ideal for measurement equipment and critical links.
ST connectors offer quick bayonet coupling, allowing fast installation in patch panels and wall outlets.
Combining these two on OM3 fiber gives you industrial-grade stability with data-center-grade bandwidth.

Real-World Performance
OM3 fiber supports 2000 MHz·km bandwidth at 850 nm, which enables:
-
10G Ethernet up to 300 meters
-
40G and 100G up to 100 meters
This makes the FC–ST OM3 jumper suitable for:
-
High-speed industrial Ethernet
-
Optical test and measurement systems
-
Telecom and metro edge networks
-
Data center cross-connects
-
Automation and control systems
Manufactured for Signal Integrity
Each cable is assembled using precision ceramic ferrules, UPC polishing, and automated interferometer inspection. Both fiber channels are 100% tested for insertion loss and return loss, ensuring stable transmission even in high-vibration or high-temperature environments.
The LSZH jacket option meets modern fire-safety standards for data centers and commercial buildings.
Professional Q&A
Q1: How is OM3 different from 62.5/125 fiber?
OM3 has much higher bandwidth and supports 10G–100G, while 62.5/125 is limited to 1G.
Q2: Why use FC connectors in high-speed links?
FC’s threaded metal coupling prevents micro-movement that can cause signal fluctuations in sensitive optical systems.
Q3: Is this cable suitable for data centers?
Yes. OM3 supports 10G, 40G, and 100G short-reach links commonly used in data centers and cloud infrastructure.
