Multiple LP-mode fiber designs for mode-division multiplexing

摘要

The specification describes modified step index and GRaded INdex (GRIN) fibers with low core relative delta (near 0.8 %) which have desirable properties for transmission. These lower delta fibers have lower attenuation losses due to reduced Rayleigh scattering, which is desirable to improve performance in multiple mode multiplexing. The fiber designs include optimized raised triangle profiles, and depressed cladding profiles, to support two and four LP modes.
