Ultra Long Haul Success Story

Background

A primary electricity provider in the LATAM region required a high-capacity optical backbone to interconnect critical operational sites and enable future scalability. The network needed to transport multiple high-capacity ultra-long spans without intermediate amplification points, ensuring secure, reliable, and low-latency transmission across challenging fiber routes.

PacketLight was selected to design and deliver a turnkey DWDM/OTN solution leveraging advanced Raman amplification to extend reach and maintain OSNR across long-haul fiber segments.

Business Challenge

The provider required a resilient network to build their ultra-long-haul point-to-point network:

  • Amplification – there were no intermediate amplification sites along critical spans, requiring high-gain, distributed amplification.
  • Ultra-long-haul – high performance demands and add/drop service connections.
  • Fiber attenuation sensitivity - requiring careful optical design and route engineering.
  • Scalability – future-proof for increased service count, including 200G and beyond.
  • Resilience – mission-critical infrastructure with minimal maintenance burden.

Network Scope

  • 1,500 km of national-scale backbone connecting operational hubs.
  • Point-to-point and add/drop capabilities across multiple service sites.
  • Spans engineered to exceed traditional EDFA-only reach using counter-propagating Raman amplification for up to an additional 12dB gain with negative noise figure.

Deployed Devices

  • PL-2000T 800G | 4 x 200G – Multi-service 200G transponders with integrated OTN functionality, transporting Native Ethernet (10GbE/100GbE) and OTN services.
  • PL-1000R Raman– High-gain amplifiers, with optional hybrid EDFA-Raman configurations for maximum span reach.
