Challenge: Building protected backhaul link connected to a subsea network, shared by three telecom service providers.
Solution: PacketLight deployed 200G muxponders, ROADMs, EDFAs and passive devices to build the link.
Success: PacketLight built a robust, redundant point-to-point 200G link, closing a ring between two subsea cables.
Background
The telecom service provider (The Provider) self-owns its subsea fiber optic infrastructure, ensuring seamless connectivity, and delivering a comprehensive range of communication services, including voice, data, internet, and video, catering to individuals, businesses, and organizations across Latin America and the Caribbean.
By enabling reliable and secure communication, The Provider empowers businesses to thrive and individuals to stay connected in today’s increasingly digital landscape.
Challenge
The Provider required a robust backhaul infrastructure to connect two subsea cables at their termination point in Jacksonville and in Miami. This backhaul network spans Eastern Florida, creating a redundant point-to-point (PTP) between the 2 submarine cables landing sites.
The Solution
To meet their requirements for a robust DWDM transport network, The Provider deployed PacketLight’s carrier-grade solutions, including the PL-2000M 200G Muxponder, PL-1000RO ROADM and PL-1000IL Amplifier device. PacketLight designed and implemented a high-capacity backhaul network of 48x200G wavelengths connecting the Provider’s subsea cables at their Miami and Jacksonville termination point (Figure 1). The infrastructure supports future migration to 400G wavelengths.
The resulting PTP establishes a redundant ring between the two submarine cables but also creates a shared network supporting three customers (Figure 2).
Each service provider operates on a dedicated spectrum of the fiber using ROADM technology. This allows multiple networks to share the same fiber and amplification sites while remaining completely isolated in terms of wavelengths and traffic.
Success
The implementation of PacketLight’s solution successfully established a reliable backhaul infrastructure for The Provider, linking two subsea cables with a seamless point-to-point (PTP) network across Eastern Florida. The solution not only ensured robust connectivity between Miami and Jacksonville but also enabled redundancy across key locations, enhancing network resilience. The completed network supports three customers, optimizing bandwidth utilization and lowering operational costs. The advanced features of PacketLight’s devices provide scalability, allowing The Provider to easily accommodate future growth and evolving service demands. This infrastructure positions The Provider as a leader in delivering secure, high-performance communication services.
