Difference between G652 fiber and G654 fiber
After the core diameter increases, the cutoff wavelength of the fiber will not increase. It is not difficult to understand that the name of G.654 fiber is:

E is a single-mode optical fiber engineered specifically for ultra-long-haul and submarine networks. To support these high capacity systems in terrestrial backbone networks, low attenuation and large core area fibers compliant with Recommendation ITU-T G 654. E, allow for the provision of an additional network margin that can be leveraged to enable reliable, high-data-rate transmissions over longer spans and extended reach. We will see how, in complementarity with technological advances in the active layer, this fibre offers a sustainable.
