Dark Fiber
Dark fiber in China — the product the big three carriers won't sell you
Overview
China Telecom, China Unicom, and China Mobile don't lease dark fiber. Full stop. But we work with specialized regional fiber operators who do — and for high-bandwidth scenarios, dark fiber beats P2P leased lines on both cost and control. You get dedicated fiber pairs with complete optical-layer freedom: your transceivers, your DWDM equipment, your protocol. We handle the partner sourcing, contract negotiation, and ongoing management. Cheaper than traditional circuits at scale, with none of the carrier restrictions.
Key features
- Dark fiber pairs from specialist operators — a product category unavailable through direct carrier negotiation
- Complete optical-layer control: your transceivers, your DWDM, your choice of protocol
- Metro (intra-city) and long-haul (inter-city) routes available through our operator network
- Unlimited bandwidth potential — upgrade capacity by swapping optics, not renegotiating contracts
- Physically diverse path options sourced from multiple independent fiber operators
- Full lifecycle management: operator sourcing, contract negotiation, SLA enforcement, fault resolution
Why choose Dark Fiber
- Access a product the big three carriers don't offer — our operator relationships make this possible
- Significantly lower TCO than P2P leased lines at high bandwidth (100 Gbps+) — you're leasing glass, not a service
- Complete protocol freedom — no carrier-imposed restrictions on what runs over the fiber
- Physical-layer security — dedicated fiber, no shared infrastructure, no carrier equipment inline
- Scale bandwidth independently: upgrade optics when you need more, don't wait for carrier approval
Use cases
Data center interconnects at 100 Gbps+ where leased line costs become prohibitive
High-frequency trading platforms requiring deterministic latency at the physical layer
Research and education networks needing dedicated, high-bandwidth optical infrastructure
Content delivery and media production transferring massive datasets between facilities
