Price of round-port fiber optic coupler

Fiber optic round port couplers typically range from $2 to $50 per unit depending on type, mode, and manufacturer.

General Pricing Overview

The cost of a fiber optic round port coupler varies based on several factors:

• Type of coupler: Fused Biconic Taper (FBT) couplers are generally more affordable, while Planar Lightwave Circuit (PLC) couplers and WDM couplers are higher-end and more expensive .
• Mode: Singlemode couplers usually cost more than multimode couplers due to tighter tolerances and lower insertion loss requirements .
• Port configuration: Simple 1x2 or 2x2 couplers are cheaper, whereas 1x8, 1x16, or high-power couplers can cost significantly more .
• Connector type: LC, SC, ST, or MTP connectors can influence price, with field-terminable or specialty connectors being more expensive .
• Quantity: Bulk purchases often reduce the per-unit cost, while single units from retailers like Amazon or Mouser may be at the higher end of the range .

Typical Price Ranges

• Basic FBT 1x2 or 2x2 couplers: $2–$10 per unit .
• PLC 1x4 or 1x8 couplers: $15–$50 per unit .
• High-power or dual-window couplers: $30–$100 depending on specifications .
• Retail packs (e.g., 20 LC couplers): $25–$60 on platforms like Amazon .

Where to Purchase

• Mouser Electronics: Offers a wide selection of fiber optic connectors and couplers with datasheets and pricing by quantity .
• EFB-Elektronik: Specializes in singlemode, multimode, and custom couplers, including PLC and FBT types .
• Amazon: Convenient for small quantities and pre-packaged sets, suitable for testing or small installations .
• DigiKey: Provides a large inventory of connector assemblies and couplers with same-day shipping .
• Thorlabs: Focused on high-performance couplers for lab and industrial applications, including PLC splitters and polarization-maintaining couplers .

Recommendation

For budget-conscious projects, FBT couplers or small retail packs from Amazon or Mouser are cost-effective. For high-performance or multiport applications, PLC couplers from Thorlabs or EFB-Elektronik are recommended despite higher prices. Always check insertion loss, wavelength range, and connector compatibility before purchasing to ensure proper network performance.
