    摘要: In some embodiments, an optical fiber transmission link, includes a length of dispersion compensating fiber (DCF), the dispersion compensating fiber coupled to a length of single-mode fiber (SMF) having a zero dispersion wavelength of 1300 nm to 1324 nm; wherein the optical fiber transmission link comprising the dispersion compensating fiber coupled to the single-mode fiber and operating at wavelengths between 1265 nm and 1375 nm increases maximum link lengths of the optical fiber transmission link by more than 60% as compared to the link length of the optical fiber transmission link with the single-mode fiber only; and wherein the maximum link length is calculated from the maximum allowed positive and negative accumulated dispersion at wavelengths between 1265 nm and 1375 nm.

    摘要: The present disclosure provides a universal optical fiber (100). The universal optical fiber (100) includes a core (102) extended from a central longitudinal axis (110) to a first radius r1. In addition, the universal optical fiber (100) includes a buffer clad (104) region extending from the first radius r1 to a second radius r2. Further, the universal optical fiber (100) includes a trench region (106) extending from the second radius r2 to a third radius r3. Furthermore, the universal optical fiber (100) includes a cladding (108) extending from the third radius to a fourth radius r4. Moreover, the core (102), the buffer clad region (104), the trench region (106) and the cladding (108) are concentrically arranged.

    摘要: The present invention relates to an ultra-low loss optical fiber for long haul communications (100) comprising a core region (102) defined by a core relative refractive index and a cladding region surrounding the core region, defined by a cladding relative refractive index. In particular, the core region comprises a relative refractive index in a range of −0.06% to +0.06% and the cladding region is down-doped for entire radial cladding thickness. Moreover, the cladding region further comprises an inner cladding region (104) defined by an inner cladding relative refractive index and an outer cladding region (106) defined by an outer cladding relative refractive index. The inner cladding relative refractive index is less than the outer cladding relative refractive index.
