It is part of the 106397 series, built around a Zirconia ceramic ferrule that provides the precision alignment singlemode links demand — the 125.5 µm cladding diameter matches standard singlemode fiber (G.652). The blue boot and housing color code it for singlemode, so you can grab it out of the kit without reading a label. The latch lock fastening keeps the connector seated in the adapter, and the integrated strain relief protects the fiber at the back of the ferrule from the bending and tugging that happens when you route patch cables through a tray. ## Field Installation Note This is a field-terminable LC plug — the zirconia ferrule is pre-polished in some variants, but verify the termination method (field polish vs no-polish) from the product drawing before you break out the splice trailer. The strain relief boot is molded to fit a specific cable diameter; confirm your cable jacket OD matches the boot entry. And keep the dust cap on until you mate it — grit on a singlemode ferrule face is a light-killer.","metaTitle":"Molex 1063971902 LC Singlemode Plug, Blue Boot","metaDescription":"Molex 1063971902 LC simplex plug for singlemode fiber.

Duplex connectors house two simplex connectors side by side in a single clip or housing, carrying both transmit and receive in one assembly. For bidirectional links you need two simplex connectors or one duplex assembly."},{"question":"Where can I buy the Molex 1063971902?","answer":"This part is sourced through independent distribution and quoted to order against an RFQ.
