Description
Designed for Stability in Demanding Installations
Both FC and ST connectors are known for their positive locking mechanisms. The FC end uses a threaded coupling to prevent micro-movement, while the ST end locks with a twist-and-click bayonet, making the cable resistant to vibration and accidental disconnects.
With UPC polishing on both ends, fiber cores make smooth physical contact, keeping insertion loss low and return loss stable, which is especially important for test and monitoring systems.

Real-World Performance
Using 50/125 µm multimode fiber at 850 nm, this cable supports:
-
10G Ethernet up to 300 m (OM3)
-
40G and 100G multimode links up to 100–150 m
This makes it suitable for:
-
Industrial Ethernet networks
-
Campus and building backbones
-
Fiber test equipment
-
Optical distribution frames
-
Security and monitoring systems
Built for Long-Term Reliability
Each patch cord is assembled with high-precision ceramic ferrules and inspected using automated interferometry and insertion-loss testing. This ensures consistent optical alignment and repeatable performance over thousands of connection cycles, even in high-traffic patching environments.
The LSZH jacket option further supports installations in data centers and public buildings where fire safety and low smoke emission are required.
Professional Q&A
Q1: What makes FC and ST connectors good for industrial use?
Both use locking mechanisms that resist vibration and accidental unplugging, making them ideal for harsh or active environments.
Q2: Is this cable suitable for 10G Ethernet?
Yes. With OM3-grade 50/125 fiber, it supports 10G links up to 300 meters at 850 nm.
Q3: Can this cable be used with test instruments?
Absolutely. FC connectors are common on OTDRs and optical power meters, while ST is widely used on distribution frames.
Q4: Does UPC polishing affect signal quality?
Yes. UPC provides low insertion loss and stable return loss (≥30 dB), which improves measurement accuracy and transmission reliability.
