Where to Buy Fiber Couplers

The G&H line of HI REL fused fiber optic components are available in PM and SM form. They are deployed in environments such as undersea and space where the costs of component replacement are prohibitive and reliability is of premier concern.

G&H is established as a preferred supplier of these components to most major undersea telecommunications equipment manufacturers. Our HI REL capability is built upon the foundation of an extended history of also manufacturing very reliable components for land-based (or terrestrial) systems in volume.

AMS Techno­logies provides a broad variety of of fiber couplers for single mode (SM), multi mode (MM) and polarization maintaining (PM) fibers for various applications:

• SM couplers & combiners, also in low-loss fused fiber technology
• module-style SM couplers & combiners in small or 19-inch-cases
• fused MM couplers & combiners
• Fused bidirectional MM fiber optic star couplers
• PM couplers & combiners with customizable coupling ratio and/or wavelength
• fused PM couplers & combiners
• PM couplers based on bow-tie fibers
• high-power MM N×1 pump combiners for high-power fiber laser applications
• MM power combiners, also with signal feedthrough
• high temperature couplers for up to +250°C
• sub-zero PM couplers operating from −55°C
• fused dual-clad fiber (FDCF) couplers

Focuslight Technologies has fiber couplers which allow one to couple the light from a single emitter or from multiple emitters into a single fiber with only one lens element. They consist of a monolithic glass block with two opposite crossed cylindrical surfaces and mounting surfaces. The light of the fast and slow axes is collimated by one cylindrical lens to produce an almost symmetrical focus.

CSRAYZER’s polarization-maintaining filter or fused coupler series products are used to split inputs from a polarization-maintaining optical fiber according to the given coupling ratio. They are widely used in fiber lasers, optical fiber amplifiers, optical fiber communications and fiber sensors, having compact dimensions, low insertion loss, low polarization dependent loss and high stability, and the ability to work under different temperature conditions.

DK Photonics uses a unique fusing technique and polarization-maintaining fibers to fabricate the polarization maintaining fused coupler (PMC). The coupling ratio can be selected according to the customer’s request. It features low excess loss, small size and high polarization extinction ratio. PMC is widely used for optical sensors and optical gyros.

TOPTICA´s COOL patent pending fiber coupling concept is new, because it does not use any mechanical micro adjustable parts, which normally are the first to move due to thermal or mechanical influences.All major optical components are solidly mounted and the optical micro alignment is unsusceptible to mechanical and thermal distortions or translations.
