Fiber polarization coupler price

Polarization-maintaining (PM) fiber couplers typically range from $150 to over $1,000 depending on type, specifications, and manufacturer.

Price Overview

The cost of a fiber polarization coupler depends on several factors, including the fabrication method, wavelength range, insertion loss, polarization extinction ratio (PER), and optical power handling. Typical price ranges are: Fusion Couplers: These offer the lowest insertion loss (~0. 3 dB) and high power handling, generally priced between $300 and $1,000 for standard single-mode PM couplers.

Micro-

Optic Couplers: With ultra-broad wavelength bandwidth (±200 nm) and high PER (>30 dB), these are slightly more expensive due to advanced fabrication, often $500–$1,200. Planar Lightwave Circuit (PLC) Couplers: Compact and cost-effective for high port counts, prices can start around $150–$500, but may have higher insertion loss and lower power handling.

Factors Affecting Cost

Coupling Ratio: Standard ratios like 50: 50 or 90: 10 are common, but custom ratios or ultra-low tap ratios (0. 1% or less) increase cost. Wavelength Range: Broadband couplers covering 400–2000 nm or specialized telecom bands (1260–1620 nm) are more expensive.

Fiber Type: Single-mode (SM), multimode (MM), double-clad (DC), or PM fibers influence pricing due to manufacturing complexity. Power Handling: High-power couplers (up to 100 W) require premium materials and fabrication, raising the price. Customization: Custom lengths, connectors (LC, SC, MTP, E2000), or integrated filters/polarizers add to cost.

Recommendation

For budgeting purposes, expect to pay $150–$1,200 depending on the coupler type, wavelength, and power requirements. For precise pricing, it is recommended to request a quote from suppliers, as costs vary with specifications, volume, and optional features.
