Why Dark Fiber

Your Fiber. Your Rules.

Unlike shared carrier services, KIRZ dark fiber gives you complete ownership of the optical path — ideal for organizations that demand deterministic latency, maximum security, and full bandwidth control.

Zero Contention

Dedicated, unlit fiber strand — no sharing with other customers. Your bandwidth is your bandwidth, 100% of the time.

Physical Isolation

No shared switching fabric or aggregation layer. Ideal for financial institutions, government, and regulated industries.

Protocol Agnostic

Run any protocol over your fiber — Ethernet, DWDM, OTN, FC. Full freedom to deploy your own optics and equipment.

Scalable Capacity

Start with 1G, scale to 100G or beyond by upgrading your own transponders. No renegotiation with KIRZ required.

DCI Ready

Direct fiber between 30+ Bangkok data centers via KIRZ's own route infrastructure. Sub-millisecond cross-DC latency.

MEA and EGAT Extension

Via strategic partnerships with MEA (Bangkok metro) and EGAT OPGW (nationwide + cross-border), extend reach beyond KIRZ's own network.

Use Cases

Who Uses Dark Fiber

Dark fiber is the right choice when shared carrier services cannot meet your performance, security, or compliance requirements.

Financial Services

Low-latency trading, core banking interconnect, DR replication between sites with deterministic throughput.

Data Center Operators

High-capacity backbone between facilities. Carrier-neutral DCI without relying on third-party transit providers.

Telecom and ISPs

Last-mile fiber lease, backbone extension, and PoP interconnect within Bangkok without building your own infrastructure.

Government and Defense

Physically isolated, auditable fiber path with no shared infrastructure — required for classified and sensitive workloads.

Enterprise Campus

Multi-building campus connectivity with private fiber — no monthly bandwidth caps, no congestion, full control.

Cloud and CDN Providers

Direct fiber to Bangkok data centers for peering, cache node interconnect, and high-throughput origin connections.
