Paper Abstract

We propose two mode optical fibers (TMFs) with minimally low differential modal delay (DMD) slope which are suitable to compensate DMD in wide wavelength range. All fabricated TMFs composed of a graded index core and a depressed inner claddings have low DMD slopes of less than |0.15| ps/km/nm, low optical loss of less than 0.21 dB/km for LP01 and LP11 modes respectively and low mode coupling ratio of less than -35 dB at the wavelength of 1550 nm. All TMFs have the similar effective area of 120 μm2 for LP01 mode and 160 μm2 for LP11 mode at 1550 nm. Moreover, it is clarified that a DMD compensation transmission line composed of the fabricated TMFs can successfully achieve the DMD of below |4.0| ps/km in the C+L band and mode conversion ratio of less than -30 dB at splice points.
