Patchcord FC/UPC – FC/UPC Singlemode OS2 9/125 G675A1 Duplex Zip 2.0mm OFNR Yellow

Patchcord FC/UPC – FC/UPC Singlemode OS2 9/125 G675A1 Duplex Zip 2.0mm OFNR Yellow from Red Cable Technology (RCT) is a Shaxon duplex patch cord for singlemode runs that still call for FC hardware. It puts high-quality FC/UPC connectors on both ends of 9/125 OS2 bending-insensitive single-mode fiber inside a rugged yellow 2.0mm duplex zip cord OFNR jacket.

Features & Specs:

• FC/UPC to FC/UPC duplex patch cord, 9/125 singlemode OS2
• Rugged yellow 2.0mm duplex zip cord jacket, OFNR rated
• High-quality FC connectors: the threaded connector with an aligned key — once positioned, it stays in place with perfect precision; once widely popular across fiber optic networks, now increasingly replaced by SC and LC
• Polarity clearly marked with yellow polarity labels
• G675A1 bending-insensitive single-mode fibre: good resistance to maro-bending with low maro-bending sensitivity and low water-peak level, comprehensively optimized for use in the O-E-S-C-L band (1260–1625 nm); good resistance to additional losses from low maro-bending in the 1625 nm wavelength region — supporting L-band applications and allowing easy installation without excessive care when storing the fibre

Where singlemode fits

When weighing on-premises and access network fiber replacement or new installation, we highly recommend replacing legacy OS1 with a new bend-insensitive OS2 (ITU-T G.657A1) SMF cabling system to support longer reach with enhanced link performance. Multi-mode fiber is typically cost effective for inside buildings or corporate campuses, while single-mode is better suited for longer distance runs — single-mode transmits farther but typically requires more expensive equipment. 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.

About the standards behind it

The International Telecommunication Union (ITU) is the United Nations specialized agency for information and communication technologies — ICTs. Founded in 1865 to facilitate international connectivity in communications networks, it allocates global radio spectrum and satellite orbits, develops the technical standards that ensure networks and technologies seamlessly interconnect, and strives to improve access to ICTs for underserved communities worldwide.
