SPTel’s Dark Fibre service is uniquely diverse, extensive and secure

Businesses choose dark fibre for their connectivity needs because of its high optical performance, near invulnerable security and ability to support extreme bandwidth speeds. Because we build and own our dark fibre network, we can offer customers and partners tailored solutions to meet their stringent requirements. Whether you require the shortest path between two locations or more complex options such as diverse fibre paths with varying lead-in points into buildings, SPTel is your ideal network provider. You can decide what service platform to use and what protocols you wish to deploy over the fibre network for full control over your network usage, physical pathways and bandwidth expansion.

Benefits at a glance

  • Hassle free and easily scalable

Simply lease the dark fibre cables from us and run your network in the way that best suits your business needs. Thinking of expanding or future proofing? You’ll have the flexibility to scale your bandwidth speeds as your business needs increase.

  • Fewer delays due to 3rd party management

We manage and maintain our dark fibre cables and have direct access to the assets that they pass through (sub stations and manhole covers). They also terminate in commercial building switch rooms where we have direct access. This greatly cuts down the lead time needed to lay and maintain our dark fibre cables.

  • 24/7 dark fibre management by a Singapore based NOC

We will maintain and repair the dark fibre lines and our NOC team will always be on standby to remedy faults.

Unique dark fibre paths and path diversity for business resiliency

Need a network that has diverse path options for greater business resilience? Our dark fibre runs on a completely separate and unique path from other providers. In addition, we can provide path diversity on top of the current unique fibre paths (that’s double the diversity vs. other providers). Learn more about our network diversity here.
