STR 4500 Trunking Solution – up to 10 Gbps Diversity Links

Aviat was a pioneer in the new category of split-mount trunking solutions with our STR 600. This gave operators a compelling alternative and lower OPEX solution to traditional all-indoor N+1 trunking radios, which required a costly support environment of shelters and air-conditioning, with the resulting need for larger power systems, higher fuel costs for generators.

The next generation

STR 4500 represents the next generation of split-mount and even all-outdoor trunking applications, where up to four WTM 4500’s can be combined onto a single antenna port using an Outdoor Branching Unit (OBU), supporting up to 5 Gbps of link capacity with integrated diversity. Adding a second OBU arrangement provides the capability of up to 10 Gbps capacities, giving operators a viable choice to having to deploy fiber for long haul backbone paths, with lowest possible CAPEX and OPEX.
