Modern mobile network without fibers is incomplete. While fibers are mostly deployed in the backhaul networks, fiber-enabled fronthauling and small cells connectivityare evolving architectures that aid the mobile operators to expand the capacity and coverage of the mobile network. For a fiber-based passive fronthauling and backhauling architecture, the technical aspects of various network elements namely; transceivers, multiplexers, monitoring and protection systems need to be considered.
Currently most of the deployed mobile backhaul/fronthaul networks are point-to-point links aided by grey transceivers. But with the increasing number of fiber connections, either leasing or laying new fibers might be economically and also geographically challenging. Multiplexing of signals from multiple antennas into a single and also already existing fiber would be the best way forward. While the upgrade to colored network might look easy, mobile fronthaul networks have environmental constraints that are new when thinking of not optical access and backhaul networks.
Transceivers and multiplexers need to withstand the extreme environments where the antennas might be located. Additionally, monitoring and link protection plays a vital role in maintaining the network performance at its best. It is only by tackling the technical and business challenges step-by-step that the front-/backhaul evolution is made simple, efficient and future-proof.
