Abstract

Orthogonal ASK/DPSK labeling is a promising approach to ultra-high packet-rate routing and forwarding in the optical layer. However, the limitation on the payload extinction ratio (ER) is a detrimental effect for the network scalability and transparency. In this paper, we propose and experimentally demonstrate that mark insertion coding is an efficient technique to improve the ER tolerance in optical orthogonal ASK/DPSK labeling scheme using an ASK payload and a DPSK label. The experimental results show that by applying mark insertion coding to an orthogonally labelled signal with an ASK payload up to 40 Gb/s and a 622 Mb/s or 2.5 Gb/s DPSK label, the tolerable payload extinction ratio can be greatly increased up to 13 dB.
