Light trees were first proposed in 1978 and allow WDM systems to combine multiple signals onto a single fiber. They increase network throughput by reducing hop distances in a wavelength routed optical network. Light trees can support unicast, multicast, and broadcast traffic and require multicast-capable wavelength routing switches at network nodes and additional optical amplifiers to maintain signal power over split signals. They provide benefits like high bandwidth, ease of installation, and data security but also have disadvantages regarding cost, fragility, and technical skills required.

Ericsson Technology Review – Microwave backhaul gets a boost with multiband
With the exception of Northeast Asia, 65 percent of all cell sites will be connected to the rest of the network using microwave backhaul technology by 2020. Between now and then, the performance of microwave backhaul will continue to improve, supporting growing capacity needs through technology evolution and more efficient use of spectrum. So as the dominant backhaul media in modern networks, the ability of microwave to carry traffic plays a significant role in providing good mobile network performance.
Technology evolution, increased mobility, and massive digitalization continue to place ever more demanding performance requirements on networks. The constant pressure to increase performance translates into a need for more spectrum, and more efficient use of it – not just when it comes to radio access, but for microwave backhaul as well.
But spectrum is a finite natural resource, so technology developments not only need to be able to make use of higher frequencies, they also need to unleash the potential of all the untapped spectrum that exists.
Radio-link bonding is a well-established method for enhancing peak capacity, enabling multiple radio carriers to be aggregated into a single virtual one. So far, developments have focused on bonding carriers within the same frequency band. The multiband booster concept, however, uses radio-link bonding to aggregate carriers in different frequency bands, enabling the full spectrum potential to be unleashed.
