Description
Why This Cable Still Matters
Many buildings were originally wired with 62.5/125 μm multimode fiber, which remains perfectly capable of handling Fast Ethernet and Gigabit Ethernet. By using LC connectors on both ends, this cable allows those networks to connect directly to modern LC-equipped hardware, helping extend the life of existing fiber infrastructure while keeping upgrade costs low.

The larger 62.5 μm core makes the cable more tolerant to alignment and dust, which is useful in high-traffic patching environments.
Manufactured for Stable Optical Performance
Each LC/UPC–LC/UPC patch cord is built using high-precision ceramic ferrules and UPC-polished end faces, followed by 100% inspection and insertion-loss testing. This ensures reliable performance and consistent signal quality throughout the life of the cable.
The optional LSZH jacket supports modern fire-safety and low-smoke requirements in public and commercial buildings.
Professional Q&A
Q1: Can this cable be used for Gigabit Ethernet?
Yes. OM1 62.5/125 fiber supports 1G Ethernet up to 275 meters at 850 nm.
Q2: Is LC compatible with older multimode fiber?
Yes. LC is only the connector type — it works perfectly with 62.5/125 μm OM1 fiber.
Q3: Is this suitable for 10G?
No. OM1 fiber is intended for Fast Ethernet and 1G, not for 10G transmission.
Q4: Why choose LC–LC instead of SC–SC?
LC connectors are smaller and support higher port density, making them ideal for modern switches and compact patch panels.
