Use this reference to prepare product questions for CJC FIBRE. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Fiber optic couplers and optical module coupling equipment typically range from $10 to $500 per unit, depending on type, specifications, and customization.

Price Overview

The cost of optical module coupling equipment varies widely based on type, fiber compatibility, split ratio, and connectorization: Simplex, Duplex, and Quad Couplers: Basic couplers for single or multiple fiber connections generally cost $10–$50 per unit for standard single-mode or multimode fibers. MPO/MTP® and Hybrid Couplers: Multi-fiber or mixed-connector couplers used in data centers or high-density networks can range from $50–$200, depending on the number of fibers and precision requirements. Fused Biconical Taper (FBT) Couplers: Common in passive optical networks (PON), FBT couplers with standard split ratios (e.g., 50/50, 80/20) typically cost $15–$100, with dual-window or multi-window versions at the higher end.

Planar Lightwave Circuit (PLC) Couplers: High-performance PLC splitters for precise signal distribution can cost $100–$500, especially for 1x8, 1x16, or higher split counts.

WDM Couplers and TA

P Couplers: Devices for wavelength multiplexing or signal monitoring are usually $50–$300, depending on wavelength range, isolation, and insertion loss. Connectorized vs. Unconnectorized: Couplers with pre-installed connectors (LC, SC, FC, ST) are more expensive than unconnectorized versions, which require splicing or custom termination.

Factors Affecting Price

Fiber Type: Single-mode (SM), multimode (MM), or polarization-maintaining (PM) fibers influence cost.

PM and S

M couplers are generally more expensive due to precision requirements. Split Ratio: Custom split ratios (e.g., 1/99, 5/95) can increase price compared to standard 50/50 or 80/20 ratios. Wavelength Range: Dual-window or wideband couplers covering multiple wavelengths are costlier than single-window devices.

Quantity and Volume Discounts: Bulk orders often reduce per-unit cost, while small quantities may incur higher prices. Customization: Special designs, hybrid couplers, or high-power handling units increase cost significantly.

Purchasing Tips

Request individual quotes from suppliers like EFB-Elektronik, Thorlabs, or OZ Optics for precise pricing. Consider technical specifications such as insertion loss, directivity, and polarization-dependent loss (PDL) to ensure compatibility with your network. Evaluate whether connectorized or unconnectorized couplers are more suitable for your installation to balance cost and convenience.

In summary, optical module coupling equipment prices range from $10 for basic couplers to $500 or more for high-performance, multi-fiber, or specialized devices, with the final cost influenced by fiber type, split ratio, wavelength range, and customization requirements.
