LC/UPC–LC/UPC-OM3-DX Multimode Fiber Optic Patch Cord

Description

Made for Modern High-Speed Optics

OM3 fiber is optimized for 850 nm VCSEL light sources, the backbone of short-reach Ethernet. With a 2000 MHz·km bandwidth, it easily supports:

• 10G Ethernet up to 300 m

• 40G and 100G up to 100 m

LC connectors allow twice the port density of older SC connectors, helping reduce panel space and cable congestion in dense racks.

Technical Specifications

Where This Cable Is Used

• Switch-to-switch and switch-to-server links

• Data center cross-connects

• Enterprise LAN backbones

• Cloud and AI computing clusters

• High-speed storage networks

OM3’s low attenuation and high bandwidth make it ideal for high-port-count environments where performance and consistency matter.

Precision Manufacturing for Low Loss

Each LC-LC OM3 jumper is assembled using high-grade ceramic ferrules and UPC-polished end faces, then inspected and tested for insertion loss, return loss, and end-face geometry. This guarantees stable optical performance across thousands of plug-and-play cycles.

The LSZH jacket option supports modern fire-safety standards in data centers and commercial buildings.

Professional Q&A

Q1: Is OM3 still relevant for new installations?
Yes. OM3 remains a mainstream standard for 10G, 40G, and 100G short-reach links in data centers.

Q2: Can this cable be used with SFP+ modules?
Absolutely. LC connectors are the native interface for SFP, SFP+, and QSFP optics.

Q3: What is the difference between OM3 and OM4?
OM4 supports longer 100G distances, but OM3 is more cost-effective and still meets most rack-to-rack and row-to-row needs.

Q4: Does UPC polishing affect signal quality?
Yes. UPC reduces back reflection and keeps return loss ≥30 dB, improving link stability.
