Non-equidistance dual-fiber 10G-EPON for evaluating emulated ultra-high splitting ratio passive optical network architecture using hollow-core fibers

An ultra-high splitting ratio passive optical network (PON) architecture using a hollow-core fiber cable has been proposed. To verify whether existing PON implementation is applicable to emulate the proposed architecture using the small number of actual equipment environment, we examined commercially available 10 Gbps Ethernet PON (10G-EPON) equipment. The verification was performed by configuring a dual-fiber transmission 10G-EPON with a maximum distance difference of 11 km between the upstream and downstream fibers. We report that we were able to confirm the stable operation of dynamic bandwidth allocation under high load conditions with actual traffic flows.
