PROBLEM TO BE SOLVED: To provide an improved step index and graded index (GRIN) fibers with low core relative delta (near 0.8%) which have desirable properties in transmission.SOLUTION: Lower delta fibers have lower attenuation losses due to reduced Rayleigh scattering, which is desirable to improve performance in multiplexing of a plurality of modes. Fiber design includes optimized raised triangle profiles, and depressed cladding profiles, to support two and four LP modes.SELECTED DRAWING: Figure 1 |
