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

Patchcord LC/UPC – LC/UPC Singlemode OS2 9/125 G675A1 Duplex Zip 2.0 mm OFNR Yellow from Red Cable Technology (RCT) is a duplex zip patch cord with high-quality LC/UPC connectors on both ends, built on 9/125 OS2 singlemode bend-insensitive fiber. The rugged yellow 2.0 mm duplex zip-cord OFNR jacket handles well in the rack, and polarity is clearly marked with yellow polarity labels so the A/B orientation is obvious at a glance.

Features & Specs:

• LC/UPC – LC/UPC, 9/125 OS2 singlemode, duplex zip cord, 2.0 mm OFNR yellow jacket
• LC connector: highly popular in single-mode networks, known for good performance and small size; the 1.25 mm ferrule is roughly half the size of an SC — it’s often called the little connector; a small form factor (SFF) connector designed to join LC fibers wherever connection or disconnection is needed
• G675A1 bend-insensitive single-mode fiber: carries all the standard features with good resistance to macro-bending, low macro-bending sensitivity, and a low water-peak level
• Comprehensively optimized for the O-E-S-C-L band (1260–1625 nm); offers good resistance to additional losses from low macro-bending in the 1625 nm wavelength region — this supports L-band applications and allows easy installation without excessive care when storing the fiber
• Upgrade recommendation: replace legacy OS1 with a new bend-insensitive OS2 (ITU-T G.657A1) SMF cabling system to support longer reach with enhanced link performance
• For ultra-long-distance transmissions that use exclusively C-band and L-band with optical amplifiers, check the ITU-T recommendations for the most appropriate SMF type
• Multi-mode fiber is typically cost-effective inside buildings or corporate campuses, while single-mode suits longer distance runs; single-mode transmits over greater distances but usually needs more expensive equipment; multi-mode stays cost-effective where lengths don’t exceed a few hundred meters
