Description
Built for Established OM1 Fiber Systems
Although modern data centers favor higher-grade fiber, 62.5/125 μm OM1 is still widely deployed in buildings and facilities around the world. This patch cord allows those systems to continue operating reliably at 850 nm and 1300 nm, supporting common applications such as Fast Ethernet and Gigabit Ethernet.
The UPC-polished fiber end faces ensure smooth physical contact, keeping optical loss low and signal reflections under control.

Where This Cable Is Commonly Used
-
Campus and building fiber backbones
-
Security and surveillance fiber links
-
Industrial control networks
-
Telecom and fiber distribution frames
-
Legacy LAN infrastructure
The larger 62.5 μm core offers good alignment tolerance, which is particularly useful in installations with frequent patching and reconfiguration.
Manufactured for Long-Term Reliability
Each ST/UPC–ST/UPC patch cord is assembled with high-precision ceramic ferrules and UPC-polished end faces, then tested for insertion loss, return loss, and end-face geometry. This ensures stable performance even after thousands of connection cycles in busy fiber closets or control rooms.
Professional Q&A
Q1: Is ST–ST still used in modern networks?
Yes. While it is not used in new data centers, it is still widely used in legacy buildings, CCTV systems, and industrial fiber networks.
Q2: Can this cable support Gigabit Ethernet?
Yes. OM1 62.5/125 fiber supports 1G Ethernet up to 275 meters at 850 nm.
Q3: Why is ST preferred in industrial environments?
ST connectors use a bayonet locking mechanism that resists vibration and accidental unplugging.
