G654:Ultra low loss optical fiber, mainly used for transoceanic optical cable. The common core is pure SiO2,while the ordinary ones need to be doped with germanium. As a leading fiber optic manufacturer with 21 years of experience, GL FIBER specializes in producing high-performance G. C, for long-haul and high-speed 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. Sumitomo Electric Industries, Ltd. (Sumitomo Electric) produces a wide range of products from. G655 fiber is ideal for DWDM long‑haul transmission systems to avoid nonlinear effects. 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.
