Patchcord LC/UPC – LC/UPC 50/125 Multimode OM3 Duplex Zip 2.0mm OFNR Aqua

**Patchcord LC/UPC – LC/UPC 50/125 Multimode OM3 Duplex Zip 2.0mm OFNR Aqua** from **Red Cable Technology (RCT)** is a laser-optimized **OM3 50/125 multimode** patch cord with high-quality LC connectors on both ends. The rugged **aqua 2.0mm duplex zip OFNR jacket** and clearly marked yellow polarity labels keep installation and troubleshooting straightforward.

**Features & Specs:**

• LC/UPC to LC/UPC connector configuration
• OM3 50/125µm laser-optimized multimode fiber (LOMMF), designed for use with 850 nm VCSELs
• Rugged aqua 2.0mm duplex zip cord OFNR jacket
• Polarity is clearly marked with yellow polarity labels
• LC connectors use a 1.25mm ferrule — approximately half the size of an SC connector — for good performance in a small form factor (SFF) package; the “little connector” built to join fibers where connection and disconnection are required
• OM3 supports 10 Gigabit Ethernet at lengths up to 300 meters; refined production techniques have enabled 40 Gigabit and 100 Gigabit Ethernet up to 100 meters — 10 Gigabit Ethernet remains its most common use
• Multimode fiber is cost-effective for inside buildings or corporate campuses where runs don’t exceed a few hundred meters; singlemode suits longer distance runs but typically requires more expensive equipment

## Duplex zip for everyday patching

These Shaxon patch cords are a workhorse for standard duplex patching. Polarity is clearly marked with yellow polarity labels, so techs can verify orientation at a glance. The rugged aqua 2.0mm duplex zip cord jacket stands up to daily handling in racks and panels.

## OM3 performance notes

OM3’s suggested jacket color is aqua. Like OM2 it uses a 50µm core, but the cable is optimized for laser-based equipment that uses fewer modes of light — the optimization that makes 10 Gigabit Ethernet at lengths up to 300 meters possible. Since the standard was issued, optical fiber manufacturers have greatly refined their manufacturing processes, and cables can now be made that support 10 GbE up to 400 meters. Newer deployments often use this laser-optimized 50/125µm multimode fiber (OM3), whose bandwidth supports 10 Gigabit Ethernet up to 300 meters. For other ultra-long-distance transmissions that employ exclusively C-band and L-band with optical amplifiers, refer to the ITU-T recommendations for the most appropriate SMF types. When replacing or installing on-premises and access network fiber, we recommend replacing legacy OS1 with a new bend-insensitive OS2 (ITU-T G.657A1) SMF cabling system for longer reach and enhanced link performance. The International Telecommunication Union (ITU), founded in 1865 to facilitate international connectivity in communications networks, is the United Nations specialized agency for information and communication technologies (ICTs) that develops the technical standards ensuring networks and technologies interconnect seamlessly.
