The Super-PON concept and its technical challenges

Long-Reach 10 Gbps Ethernet Passive Optical Network based on a Protected Ring Architecture

“…Secondly, in long-reach 10G EPONs strict service availability requirements are expected, which will probably require the incorporation into the network design of appropriate protection mechanisms. The Super-PON concept arises as a way to answer some of these concerns [4]. However, this concept relies on a tree-and-branch topology that has some weaknesses in dealing with highly survivable designs, and at the same time suffers from amplified spontaneous emission (ASE) noise funneling in the upstream direction, which significantly degrades the upstream signal [4].…”

Minimization of amplified spontaneous emission noise in upstream superPON 512 ONU, 10 Gbit/s

“…The possibility of deploying SuperPON 8192 ONU had also been investigated by considering the minimum noise in the several architectures [4]. The high speed upstream SuperPON of 10 Gbit/s with ONU of 1024 also discussed the noise issue which considers the gain at the pre amplifier receiver must operate more than 20 dB to achieve best performance [5].…”
