Description
Why SC–SC Still Matters
While LC dominates transceiver ports, SC connectors remain widely used in patch panels, ODFs, and backbone distribution frames. SC connectors offer a larger ferrule for robust coupling and a positive latch mechanism that makes them ideal for high-traffic fiber cabinets.
Pairing SC with OM3 fiber gives you a strong optical backbone that is both easy to manage and future-ready.

OM3’s low attenuation and high modal bandwidth keep signals clean even when multiple patch points are involved.
Built for Optical Accuracy
Each SC–SC OM3 jumper is assembled with high-precision ceramic ferrules and UPC-polished end faces, then inspected using interferometry and insertion-loss testing. This ensures minimal back reflection, consistent coupling, and long-term reliability.
The LSZH jacket option also meets modern fire-safety and low-smoke standards, making it suitable for dense data centers and office buildings.
Professional Q&A
Q1: Is SC–SC still suitable for modern networks?
Yes. SC connectors are still widely used in ODFs, patch panels, and backbone links in data centers and telecom rooms.
Q2: Can OM3 handle 40G and 100G Ethernet?
Yes. OM3 supports 40G and 100G up to 100 meters using 850 nm multimode transceivers.
Q3: What benefit does UPC polishing provide?
UPC reduces back reflection and keeps return loss above 30 dB, improving link stability.
Q4: Is this cable backward compatible with older multimode systems?
Yes. OM3 works with OM2 and OM1 equipment, while providing much higher bandwidth for upgrades.
