Price of Single-Mode Dual-Core Fiber Optic Indicator Light

Single-mode dual-core fiber optic indicator lights typically range from $500 to $2,500 depending on brand, features, and wavelength support. OverviewSingle-mode dual-core fiber optic indicator lights are used to detect, measure, and identify light signals in single-mode fiber networks. They are essential for attenuation testing, fiber identification, and network troubleshooting.

These devices often support multiple wavelengths (commonly 1310 nm and 1550 nm) and may include features like adjustable output power, test tones, and compatibility with optical fiber identifiers (OFI) for precise measurements. Price RangeEntry-level models from suppliers like Alibaba or specialized distributors can start around $500–$800, suitable for basic single-mode testing and dual-core detection. Professional handheld light sources such as the AFL OLS2-DUAL, which provide stabilized laser output, multiple wavelengths, and advanced testing features, typically cost $1,200–$2,500.

High-end or multi-feature units from brands like EXFO or VIAVI may exceed $2,500, offering enhanced accuracy, multiple connector adapters, and compliance with TIA/EIA standards.

Key Features to Consider

Wavelength Support: Ensure the device covers 1310 nm and 1550 nm for single-mode fiber testing. Connector Compatibility: FC, LC, SC, ST, or universal adapters for flexible deployment.

Dual-

Core Capability: Allows simultaneous testing of two cores, providing redundancy and faster measurements. Portability: Handheld units are preferred for field testing, while benchtop models may offer higher precision. Compliance: Devices should meet TIA/EIA standards for accurate attenuation and fiber identification.

Where to Buy

Alibaba: Offers a variety of single-mode dual-core fibers and indicator lights, often with bulk pricing options. Specialized Products: Stocks AFL, EXFO, VIAVI, and other brands with shipping in the USA, typically 2–4 weeks delivery. Amazon: Provides consumer-accessible fiber optic light sources, though professional dual-core models may be limited.

Fosco Connect / FiberOptics4Sale: Offers optical fiber identifiers compatible with single-mode dual-core fibers. In summary, the price depends on the brand, features, and intended use, with professional dual-core single-mode light sources generally ranging from $1,200 to $2,500, while simpler models may be available for under $1,000.
