Abstract
Embodiments of the present invention provide a method and an apparatus for allocating optical spectrum bandwidth resources. The method includes: first determine bandwidth of an OTUbase according to optical-layer frequency grid bandwidth and carrier spectrum efficiency; then construct an HO OTUflex according to bandwidth of customer service data and the bandwidth of the OTUbase, bandwidth of the HO OTUflex is a first integer multiple of the bandwidth of the OTUbase; map the customer service data into a payload area of the HO OTUflex and encapsulate overhead information; at last, modulate the HO OTUflex that carries the customer service data to a second integer number of optical channel carriers. The embodiments of the present invention apply to a scenario where customer service data is transported.
