Dark Fiber & Data Center Interconnect
KIRZ-owned dark fiber across 1,000+ km of Bangkok's aerial and underground routes. Lease dedicated capacity with zero contention, full physical isolation, and no shared switching.
Service Overview
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.
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.
