Backhaul Solutions
High capacity networks require responsive high speed backhaul transport.

iPASOLINK 250/650NEC’s iPASOLINK 250/650 is an intelligent, full-featured versatile backhaul transport platform for TDM and IP traffic. With throughput capacities of ~500 Mbps per channel, and 2 to 6-way nodal capabilities, the iPASOLINK 250/650 meets the demands of small to large backhaul links. The integrated advanced Layer 2 switching features, such as hitless AMR + QoS, End-to-end OAM, ERPS / MPLS, enable you to manage your network traffic with priority and precision, ensuring efficient bandwidth utilization, in all propagation conditions.


iPASOLINK 250/650 is a modular network element that integrates a comprehensive set of packet switching and microwave/optical features, resulting in reduced costs and a long investment lifetime.


iPASOLINK 250/650 covers mobile backhaul requirements all the way from the access tail links through the metro aggregation network:


NEC’s iPASOLINK 250/650 is supported by a strong suite of professional services and high-quality engineering. It is compatible with NEC’s market-leading NLite microwave product portfolios.
