SC/UPC–SC/UPC-62.5/125-DX Multimode Fiber Optic Patch Cord

The SC/UPC–SC/UPC-62.5/125-DX is a classic duplex multimode fiber patch cord engineered for legacy LANs, building backbones, CCTV fiber links, and industrial networks that continue to run on 62.5 μm OM1 fiber. With SC connectors on both ends, it delivers a straightforward, stable connection between fiber panels, wall outlets, and optical devices.

Although newer networks favor smaller connectors, SC remains a reliable standard thanks to its robust push-pull locking design and excellent alignment accuracy.

Description

Optimized for Installed Fiber Infrastructure

Large amounts of 62.5/125 μm multimode fiber are still installed worldwide in schools, hospitals, factories, and office buildings. This patch cord lets those networks stay operational without costly re-cabling, while maintaining clean signal quality at 850 nm and 1300 nm.

What It’s Commonly Used For

This cable is widely deployed in:

  • Fiber patch panels and wall outlets

  • Enterprise and campus networks

  • Security and surveillance fiber systems

  • Industrial control and monitoring networks

  • Legacy telecom and LAN backbones

Its 62.5 µm core provides excellent tolerance to connector alignment, making it particularly forgiving in high-mating-cycle environments.


Built for Long-Term Reliability

Every SC/UPC–SC/UPC-DX patch cord is manufactured using high-precision ceramic ferrules and UPC-polished end faces, then tested for insertion loss, return loss, and end-face geometry. This ensures consistent optical performance even after thousands of insertions.

The LSZH jacket option also supports modern fire-safety regulations for indoor and public-building installations.


Professional Q&A

Q1: Can this cable support Gigabit Ethernet?
Yes. OM1 62.5/125 fiber supports 1G Ethernet up to 275 meters at 850 nm.

Q2: Why is SC still used in many buildings?
SC connectors are durable, easy to handle, and highly reliable, making them popular in patch panels and wall outlets.

Q3: Is this suitable for 10G?
No. OM1 fiber is not designed for 10G Ethernet over standard distances. It is intended for Fast Ethernet and 1G.

Q4: Can it be installed in modern buildings?
Yes, especially in renovations and expansions where existing 62.5/125 fiber is reused to save cost.
