In the past several years, LTE networks have been upgraded using additional frequency bands, carrier aggregation, and LTE-A, and small cells have been added within macrocell coverage areas, driving up fronthaul bandwidth requirements to the point where now many operators and equipment suppliers have standardized on 10Gb/s-capable multi-rate transceivers for all their fronthaul needs, since they can meet the majority of different transport speed requirements with one device, while reducing the complexity of specific site designs and spares inventory.  Many operators, especially those leasing their fronthaul fiber, have also deployed WDM systems in their fronthaul networks, as shown below. A typical fronthaul network incorporating WDM is shown below.
