HB-T - Splice-Compatible PM Fiber

For EDFA Pump Pigtailing and Telecommunications Applications

Splice-compatible with both standard SM fibers and other PM fibers used in telecommunications
Cost-effective
Tested in accordance with Telecordia G-20-CORE Procedures

The introduction of Erbium Doped Fiber Amplifiers and the increased use of externally modulated lasers have generated a keen demand for PM fibers that combine telecommunications-compatibility with low cost. The HB980T and HB1480T have been designed specifically for the polarization multiplexing of EDFA pump diodes, and the HB1250T and HB1500T, with their nominal MFDs of 9 µm and 10.5 respectively and optional 400 µm dual-layer acrylate buffer, are ideal for both laser and integrated optic chip pigtailing.

$2-D refractive index profile of HB1500T$ With advanced photonic devices incorporating PM fibers now in volume production, multi-sourcing has become a fact of life. All HB-T fibers are designed to be highly compatible with other manufacturers’ PM fibers, with splice losses and extinction-ratios of better than 0.1 dB and –30 dB, respectively, achieved routinely.

Extinction Ratio of -35 to -38 dB
Nominal PER in an idealized deployment of 10 m laid straight

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.
