The Alcatel-Lucent 7750 Service Router (SR) is a cornerstone of high-performance networking, purpose-built for the delivery of next-generation IP services across fixed, mobile, and converged networks. Originally developed by Alcatel-Lucent and now under the Nokia brand, the 7750 SR is trusted by major telecommunications operators and large enterprises worldwide for its ability to handle the ever-increasing demands of broadband traffic, multimedia services, and cloud-based applications.
Designed with scalability, resilience, and service flexibility at its core, the 7750 SR delivers industry-leading IP/MPLS routing and switching capabilities. It operates on Nokia’s Service Router Operating System (SR OS), a feature-rich and highly reliable software platform that supports advanced routing protocols, extensive Layer 2 and Layer 3 VPN services, traffic engineering, and comprehensive quality of service (QoS) frameworks.
The platform is available in multiple form factors — from compact models ideal for metro and edge deployments, to high-capacity chassis suited for core network roles — making it a versatile solution across a range of applications. It supports carrier-grade features such as fast reroute, network slicing, and subscriber management, enabling operators to deliver differentiated services with guaranteed performance and uptime.
In addition to its performance, the Alcatel 7750 SR integrates seamlessly with network management systems, SDN architectures, and automation frameworks, allowing service providers to modernize their operations and reduce OPEX while enhancing agility and control. Its modular architecture and high port density ensure long-term investment protection and the ability to scale as network requirements evolve.
Whether deployed in an ISP backbone, enterprise WAN, or mobile packet core, the 7750 SR stands out as a robust and flexible platform designed to support the transition to fully converged, intelligent IP networks.
