DUAL PATH WAVELENGTHS

Dual Path Wavelengths is a wavelength service that pairs two diversely routed waves between the same two sites. Both circuits are unprotected, run on physically non-overlapping routes across Lumen-owned fiber and stay active at full bandwidth. The pairing carries a 99.99% availability SLA. It is available on U.S. on-net locations at 2x 100G or 2x 400G and requires both waves to be purchased together as a single point-to-point service.

Lumen documents physical route separation before service activation, giving you verification that the two paths do not overlap. Diversity covers intercity routes and gateways plus dual metro laterals into each site, and the paths are monitored after turn-up so that grooming, restoration and network changes do not quietly reintroduce shared risk over the life of the service.

Yes. Both wavelength services are active and carry full bandwidth, so you get the capacity of two circuits rather than one working path and a second path sitting idle. You control how traffic moves between them using your own routing or load balancing, which means you decide when and how traffic shifts. If one path is interrupted, your traffic continues on the other.

They suit different requirements. A protected wavelength is a single logical service with one working path and a reserved protect path, and Lumen switches traffic automatically when a failure occurs. Lumen Dual Path Wavelengths gives you two independent, fully usable circuits on diverse routes and leaves switching under your control. Choose protected wavelengths for hands-off automatic failover, and Dual Path when you want more usable capacity, documented route diversity and control over how traffic moves.

It is built for organizations running workloads that cannot tolerate an outage between two fixed locations, typically financial services, healthcare, wholesale and neocloud or AI operators connecting data centers. It fits teams that already buy diverse routes from two carriers and want the same physical separation without managing two vendors, two contracts and two support models.

Dual Path includes diverse intercity routes and gateways, dual metro laterals into each termination site, and card diversity. Chassis diversity is not included in the current offer. If your design requires separation at the chassis level, talk to your Lumen account team about how Dual Path can fit alongside the rest of your architecture.
