Pigtail ST/UPC SM G657A1 SX 0.9mm OFNR Yellow, semitight

Pigtail ST/UPC SM G657A1 SX 0.9mm OFNR Yellow, Semitight from Red Cable Technology (RCT) is a simplex fiber optic pigtail for terminating singlemode cable by fusion or mechanical splicing, built on bend-insensitive G.657A1 SM fiber with a high-quality ST/UPC connector on a yellow 0.9mm semitight OFNR lead.

Features & Specs:

• Use: terminate fiber optic cables via fusion or mechanical splicing; high-quality pigtail cable plus correct fusion splicing practices give the best possible termination performance; typically installed in ODFs, fiber terminal boxes, and distribution boxes.
• Configuration: simplex (SX), single yellow lead, 0.9mm semitight buffer, OFNR rated.
• Connector — ST/UPC: one of the most widely used connectors, especially in multimode networks such as college campuses and most buildings; spring-loaded, keyed, push-in-and-twist mechanism; bayonet mount with a long cylindrical 2.5mm ceramic or polymer ferrule to hold the fiber; very easy to use.
• Polish — UPC: polished with no angle (not exactly flat — a slight curvature for better core alignment); UPC connectors are blue, APC connectors are green.
• Fiber: singlemode, bend-insensitive G.657A1 — the de facto standard NDSF SMF for premises cabling, chosen for its optimized performance-to-cost balance; ITU-T G.657A1 and A2 are fully compliant with G.652D and deliver enhanced, low-loss fiber.
• Bend performance: minimum bending radii can be optimized, but that trades off fiber attenuation and cost; bend-insensitive NDSF is defined in ITU-T G.657 — G.657A1 (10 µm).

Singlemode vs. multimode

Singlemode gives users a greater transmission rate plus nearly 50 times the distance of multimode — at a higher price. The most basic difference is core size, along with its associated loss/attenuation and fiber bandwidth.

On the job

Drop this pigtail into your ODF, fiber terminal box, or distribution box and splice with proper fusion technique for the cleanest termination. For on-premises or access-network fiber replacement — or a new installation — we 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.
