Abstract
Elastic Optical Networking (EON) is a solution that promises to improve
infrastructure utilisation by implementing flexible spectrum allocation with small
spectrum slots instead of the rigid 50-GHz fixed grid of current DWDM
deployments. This new EON flexible grid supports Bandwidth Variable
Transponders (BVT) that can tune their bit rate and bandwidth dynamically with a
trade off between reach and capacity. However, when BVTs need to transmit at low
bit rates, part of their capacity is wasted. Therefore, the Sliceable Bandwidth
Variable Transponder (SBVT) has been proposed, which can provide even higher
levels of elasticity and efficiency to the network. SBVTs enable transmitting from
one point to multiple destinations, changing the traffic rate to each destination and
the number of destinations on demand.
The aim of this work is to identify the target cost of 400 Gb/s and 1 Tb/s SBVTs to
reduce, by at least 30%, transponder costs in a core network scenario. This target
cost is calculated in relation to estimations for non-sliceable transponders of 400
Gb/s and 1 Tb/s. In light of our results, cost savings of 30% are feasible for 1 Tb/s
transponders in the next nine years with a higher cost than non-sliceable
transponders. Savings of 30% for 400 Gb/s case are possible in the short-term before
1 Tb/s SBVTs can appear in the market. Feasibility of such savings with a target c
