Frequently asked questions

What is Layer 1 Transmission?

SD-WAN (Software-Defined Wide Area Network) is a smarter way to manage business connectivity. Instead of sending all traffic through fixed routes like traditional WAN, SD-WAN dynamically directs applications (such as video calls, cloud storage, or CRM tools) over the best available path. This means faster performance, less downtime, and more cost control.

How does Layer 1 Transmission work?

It uses dedicated point-to-point or multipoint fibre connections over carrier-grade networks, supporting technologies like OTN, DWDM, SDH, and MPLS-TP. Traffic flows directly over the physical layer, minimising latency and jitter.

What are the main benefits of using Layer 1 Transmission?

  • Guaranteed capacity – Dedicated bandwidth ensures your applications always perform at peak levels.
  • Ultra-low latency – Protocol-transparent connections minimise transmission delays, ideal for latency-sensitive workloads.
  • Scalability and flexibility – Easily expand capacity or add new locations to support growing business needs.
  • Global reach – Access hard-to-reach markets with a choice of diverse PoPs across key cities and countries.
  • High reliability – Carrier-grade networks with diverse routes and optional dark fibre pairs provide resilient, secure connectivity.

Who benefits from Layer 1 Transmission?

Organisations that move large volumes of data, run latency-sensitive applications or handle sensitive information, such as financial services, healthcare, government and multi-site enterprises.

Why choose a managed Layer 1 Transmission service?

Managing high-capacity fibre networks is complex. A managed service handles setup, monitoring and optimisation, ensuring guaranteed performance, minimal latency and reliable connectivity without burdening internal IT teams.
