HiBi PM fiber - highly birefringent, bend insensitive polarization maintaining fiber

HB Polarisation Maintaining Fibers

Bend-Insensitive Fiber for Sensor and Research Applications

Seven standard wavelengths, 488 nm to 1550 nm, usually available ex-stock

With applications for PM fibers growing at an ever-increasing rate, Fibercore Limited HB is the natural, high-performance choice for fundamental research. To give you maximum choice and versatility, HB is available in no-less than seven standard wavelength ranges from below 488 nm to beyond 1550 nm. Throughout all wavelength ranges, the standard NA of 0.16 guarantees excellent resistance to bend-induced losses.

1. The Design Wavelength is the wavelength (or wavelengths) at which the fiber is typically used. In practice, the fiber will transmit the TEM₀₀ mode at wavelengths of up to approximately 200 nm longer than the cut-off wavelength.
2. The Mode Field Diameter is a nominal, calculated value, estimated at the operating wavelength(s) using typical value of numerical aperture and cut-off wavelength.
3. Attenuation is a worst-case value, quoted for the shortest design wavelength.
4. Beat Length is measured at 633 nm for all HB fiber types. To a first approximation, beat-length scales directly with operating wavelength.
5. At the design wavelengths of 488nm and 514nm, the launched power must be considered carefully as these fibres have germanosilicate cores, and as such are susceptible to color center generation. For more information on this, please request a copy of Factnote 4.1.5.
