APCH/SPCH Hard Polymer Clad MM Fibers

Product information "APCH/SPCH Hard Polymer Clad MM Fibers"

Multi Mode; 190 to 2200 nm; Core Diameter 200 to 1500 µm; Cladding Diameter 230 to 1550 µm; Coating Tefzel (Natural & Blue); Numerical Aperture 0.37

Fiberguide’s Anhydroguide™ (APCH) and Superguide™ (SPCH) series of silica core, hard clad fibers feature a hard polymer cladding instead of a silica cladding. This hard polymer cladding enables a higher numerical aperture (NA, 0.37) than a silica cladding and reduces cost. Hard clad fibers like the APCH/SPCH series are the ideal choice for disposable medical products.

While the APCH series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SPCH variants with high hydroxyl ion concentration are suitable for the UV to visible range. Options include natural (-Z) or blue (-C) Tefzel coatings.

As an option, fibers can 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.

MPC-201 Polarization Controller
980-1620 nm; Multiple Polarization Control Modes; IL <0.6 dB; PDL <0.1 dB; PMD <0.2 ps; AL <0.1 dB; RL >50 dB Controlling the state of polarization (SOP) of an optical signal has never been easier – General Photonics’ MPC-201 multifunction polarization controller has four operational modes for complete polarization control: variable rate polarization scrambling, manual polarization adjustment, polarization modulation, and externally triggered random SOP generation. Four different polarization scrambling methods enable the SOP to a) trace out a spiral pattern about a static or rotating axis with a nearly uniform SOP variation rate for system stress tests (Tornado scrambling); b) generate a continuous trace with a Rayleigh distribution of SOP variation rate, for emulation of the SOP variation in a fiber link (Rayleigh scrambling); c) generate a continuous trace with uniform sphere coverage for PDL measurement (Triangle scrambling); or d) evenly cover the Poincaré sphere with discrete, random points at a uniform rate (Discrete scrambling). In the SOP modulation mode, each polarization control axis can be selectively controlled with a sine, square, or triangle wave of user defined frequency and amplitude. Each polarization control axis can also be controlled manually, by setting the input voltage either from the front panel controls or through a remote control interface. In externally triggered scrambling mode, discrete, random SOPs are generated in response to a trigger input, a feature desirable for recirculating loop applications or other applications requiring synchronization with other devices. Finally, the MPC-201 can emulate the Agilent 11896A polarization scrambler function, allowing it to act as a plug-in replacement for this popular but discontinued device, while offering many more advanced features. The MPC-201 polarization controller puts the user in control.
