ABC SM Couplers & Combiners

Gooch & Housego’s FFW-X single mode (SM) fused pump signal wavelength division multiplexers (WDMs) are used for multiplexing signal and pump power in erbium-doped power amplifiers, pumped by wavelengths from 960 to 1480 nm. Gooch & Housego (G&H) proprietary manufacturing technology provides uniquely low excess loss, along with low polarization and temperature dependence for all ports. The ultra-low loss of these components promotes high efficiency of use of pump power and low noise figure. These high-performance parts are available in many wavelength configurations, fiber and connector options, with standard as well as subminiature packages. They can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds. Fused Pump Signal WDMs 980 nm (FFW-xxxxx2xxx):G&H’s FFW-xxxxx2xxx series of fused pump signal WDMs, 980 nm, multiplex signal and pump power in 980, 960 or 1060 nm-pumped erbium-doped fiber amplifiers. Wavelength configurations allow for 960, 980 or 1060 nm pumping and C, L or C+L signal bands. Reliability is assured through qualification to Telcordia GR-1221, with a field proven FIT rate of <1. Fused Pump Signal WDMs 1480 nm (FFW-3xxxx21xx):The Gooch & Housego FFW-3xxxx21xx series of fused pump signal WDMs, 1480 nm, multiplex signal and pump power in 1480 nm-pumped erbium-doped fiber amplifiers. Wavelength configurations are 1480 nm – C band and 1480 nm – L band. Subminiature Pump Signal WDMs (FFW-5x1xx2xx0):G&H’s FFW-5x1xx2xx0 series of subminiature pump signal WDMs provide low-loss multiplexing of pump and signal in an ultra-short 32 mm length package. Designed for space-constrained optical amplifiers, the product is manufactured using ø80 µm cladding fiber. This enables low fiber bend radius without compromising mechanical integrity. Standard wavelengths of operation are based on 980 nm pumping and C, L or C+L signal bands. However, many other wavelength combinations are available for diverse requirements such as sensing, fiber lasers and fiber Gyros. Do not hesitate to contact AMS Technologies with your specific requirements. Reliability is assured through qualification to Telcordia GR-1221.

Multi Mode; 190 to 2400 nm; Core Diameter 50 to 1500 µm; Cladding Diameter 125 to 1650 µm; Coating Acrylate, Polyimide, Nylon, Tefzel, Aluminium, Gold; Numerical Aperture 0.12, 0.22, 0.26Fiberguide’s Anhydroguide™ (AFS/AFM/AFH) and Superguide™ (SFS/SFM/SFH) silica core, silica clad, polymer coated multi mode fibers are primarily used in photonics applications where individual or bundled large core (>50 µm) multi mode fibers are needed for the transmission of optical energy. These fibers can be coated with a variety of polymers or even metalized with aluminium or gold for extreme temperature performance. While the AFS series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SFS variants with high hydroxyl ion concentration are suitable for the UV to visible range. Options include Acrylate (-Y), Polyimide (-T), Nylon (-N), Tefzel (-Z), Aluminium (-A) and Gold (-G) coatings as well as standard (AFS/SFS), high (AFH/SFH) and low (AFM/SFM) numerical aperture. As a further option, fibers can also be provided with a broad selection of shaped tips – standard configurations as well as custom designed shapes. Shaped tip fibers provide optimum control over beam delivery and/or increased efficiency of light collection. Some fiber types can also be end capped to achieve higher coupled power into a fiber core by reducing the power density at the air / silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber cores size, but can be easily customized for a variety of fiber types and specialized applications. Additionally, all fiber types can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
