HB Bend-Insensitive PM Fiber

HiBi - Bend Insensitive PM Fiber

Bend-Insensitive Fiber for Sensor and Research Applications

Seven standard wavelengths, 488 nm to 1550 nm, usually available ex-stock
Maximum birefringence - Minimum Stress

With applications for PM fibers continuing to grow at an ever-increasing rate, Fibercore Limited 'HB' is the natural, high-performance choice for fundamental research and product development. Offering maximum choice and versatility, HB is available in no less than seven standard wavelength ranges from below 488 nm to beyond 1550 nm. A standard NA of 0.16 for all but the HB450 guarantees excellent resistance to bend-induced losses when packing and coiling the fiber, and the highly efficient Bow-Tie SAPs provide exceptional polarization maintaining ability with excellent handling characteristics.

Extinction Ratio of -30 to -35 dB
Nominal PER in an idealized deployment of 500 m wound at low tension (<5 g) on a 150 mm diameter spool.

At the design wavelength of 488 nm and 514 nm, the launched power must be considered carefully as these fibers have germanosilicate cores, and as such are susceptible to color center generation. For more information, download a copy of our Singlemode Power Handling Application Factnote.
The Design Wavelength is the wavelength (or wavelengths) at which the fiber is typically used. In practice, the fiber will transmit the single mode at wavelengths of up to ~ 200 nm longer than the cut-off wavelength.
The Mode Field Diameter is a nominal, calculated value, estimated at the operating wavelength(s) using typical values for numberical aperture and cut-off wavelength.
Attenuation is a worst-case value, quoted for the shortest design wavelength.
Beat length is measured at 633 nm for all HB fiber types. To a first approximation, beat-length scales directly with operating wavelength.
