Price of 4-core optical cable splicing sequence

A 4-core fiber optic cable typically follows a color-coded splicing sequence, and prices range from $0.40 to $1.80 per meter depending on type and environment.Splicing Sequence for 4-Core Fiber CableFor a standard 4-core fiber optic cable, each fiber is usually color-coded for easy identification. A common sequence is:Fiber NumberColorFunction1BlueTransmit (TX)2OrangeReceive (RX)3GreenSpare / Redundant TX4BrownSpare / Redundant RXSplicing Steps:Prepare the Cable: Strip the outer jacket, buffer tubes, and protective coatings to expose bare fibers .Clean and Cleave Fibers: Use a fiber cleaver to ensure a smooth, perpendicular end face.Align Fibers: For fusion splicing, fibers are aligned in a fusion splicer; for mechanical splicing, fibers are held in a gel-filled alignment sleeve .Splice Fibers: Fusion splicing uses an electric arc to weld fibers, achieving low attenuation (~0.03–0.1 dB). Mechanical splicing is faster but has slightly higher loss (~0.15–0.3 dB), .Protect the Joint: Place the splice in a protective sleeve or closure to prevent mechanical stress and environmental damage.Test the Splice: Verify continuity and attenuation using an OTDR or power meter.Price of 4-Core Fiber Optic CableThe cost depends on fiber type, jacket material, and installation environment :Indoor distribution cables: ~$0.40 per meterOutdoor or armored cables: ~$1.80 per meter100-meter reel of single-mode OS2 4-core cable: $60–$90 depending on customization and volumeFusion splicing cost per joint: $50–$150, including labor and OTDR verification Notes on Pricing:Single-mode OS2 cables are more expensive than multimode OM3/OM4.Bulk orders often receive tiered discounts.Mechanical splicing is cheaper initially but may have higher long-term maintenance costs. By following the color-coded sequence and proper splicing steps, you ensure minimal signal loss and reliable network performance while budgeting accurately for cable and labor costs.
