Ultra Long Haul Optical Transport
Expand Your Optical Backbone with Maximum Efficiency
Scalable 100G–400G Connectivity Up to 4,000 km — With Fewer Regeneration Points
PacketLight enables ultra long haul (ULH) connectivity over 1,000 to 4,000 km of fiber using compact, energy-efficient DWDM and OTN platforms. Our solutions empower carriers, infrastructure owners, and hyperscale architects to deliver SLA-grade transport, with reduced cost, complexity, and operational overhead.
Designed to work across both greenfield and brownfield environments, PacketLight allows you to scale from metro to regional to ULH, all on the same standards-based, license-free hardware.
Traditional ULH Challenges
- Bulky, high-power hardware
- Complex licensing schemes
- Proprietary platforms that restrict growth
PacketLight's Innovative Approach
PacketLight changes the game with high OSNR tolerance, tunable modulation, and compact form factors, helping you extend reach, lower total cost of ownership, and future-proof your transport infrastructure.
Solving the Challenges of Traditional Long-Haul
Key Benefits of PacketLight ULH Solutions
Optimized for Long Distances
Fewer regeneration points reach up to 4,000 km with minimized signal regeneration, even in challenging terrain or brownfield fiber.
Tunable Modulation
Support QPSK, and 16-QAM to dynamically balance capacity and distance — no license fees to adjust modulation.
High OSNR Headroom
Operates down to 17 dB OSNR with 2.5–5.5 dB more margin than traditional solutions, ideal for cascaded amplification.
Compact & Power Efficient
Deliver up to 4.8T per device with lower power draw and rack space than legacy solutions.
Vendor-Neutral Architecture
Fully interoperable with 75/100/150 GHz filters, existing DWDM infrastructure, and third-party networks.
Real-Time SLA Monitoring
Layer-1 fault isolation, performance metrics, and proactive alerts, built-in and centralized.
Software-Defined Growth
Upgrade from metro to ULH on the same device, no forklift upgrades or feature licensing.
