In this paper we describe the boundary conditions for upgrading existing 10 G optical transport networks with 40 G and 100 G channels and the operational issues in multi-rate optical networks.
The paper discusses the fundamental conceptual work and the design building blocks of a meshed optical network and gives a future outlook of the next generation optical platforms.
With increased price pressure and expanding requirements, metro, regional, and LH/ULH transport equipment are rapidly collapsing toward universal platforms. Enabling technologies and impact of this convergence on optical network architecture and design will be reviewed.
Wide-band Raman amplification offers a low cost soltiton for ultra-long-haul, high-capacity WDM transmission systems by enabling low cost designis for the terminal and line equipment. Results are shown on a 2.4Tbls all-Raman system over 1500km SSMF with standatd NRZ, RS255/239 OOB-FEC, and 50GHz channel spacing, using 100nm-bandwidth Raman line amplifiers.
The ACTS project OPEN will assess, by means of network analysis, laboratory demonstrations, and two cross-border field trials, the concept of a pan-European network with a high-level of optical transparency, using all-optical WDM technologies for transmission and routing.
