Neptec’s optical fiber couplers are fused fiber devices that combine light allowing for signal combination and amplification. Neptec offers a variety of standard, WDM, Polarization-Maintaining (PM), and high power (HP) couplers that combine multiple optical signals.

Neptec offers additional customization options such as split ratios, pigtail lengths, fiber type, and packaging. If the standard coupler below does not fit your application, we would be glad to review your specifications and quote a custom coupler for you.
