Polarization-Maintaining Single-Mode Fiber Cables
• Polarization-maintaining single-mode
• Wavelengths 360 – 1800 nm (Cut-off wave lengths from 360 to 1550 nm), each with an operational wavelength range of 100 - 300 nm (depending on cut-off wavelength)
• Special broadband fiber RGBV with an ope rational wave length range 400-680 nm
• Fiber with low attenuation (Si) for wavelengths <460 nm
• FC-APC or FC-PC fiber connector (other connector types available)
• Option: Connectors with End Caps (Details see page 50.)
• Amagnetic titanium connectors available for FC-APC or FC-PC connectors (p.51)
• Polarization direction is indicated by con nector index key
The three defining parameters of a polarization-maintaining single-mode fiber are effective numerical aperture NAe 2 , mode field diameter MFD and cut-off wavelength λco . Because of manufacturing tolerances, the mean specified values for NAe 2 and MFD may differ by up to 10%. Using fibers with end caps reduces the risk of damaging the fiber end face, by reducing the power density but without changing the numerical aperture NA of the fiber.
