Private circuits between your sites
Layer 2 EVPL, EPL, VPLS, and DWDM wavelengths between two or more sites across Southeast Michigan, or extended off-net to a partner backbone where you need to reach further. Your own private layer.
Four shapes between your sites
A private circuit between sites lets you move traffic across our network without the public internet in the path. The right shape depends on how many sites are talking, how many bits move between them, whether you want a switched Ethernet service or your own optical layer underneath, and whether the path between buildings is better served by fiber or by a radio link.
Four product shapes cover most builds: Point-to-Point Ethernet between two locations, a Wavelength when you want a transparent optical pipe, Multipoint when three or more sites need to share the same broadcast domain, and Fixed Wireless when a licensed-spectrum radio link makes more sense than waiting for fiber.
EPL and EVPL between two sites
Ethernet Private Line and Ethernet Virtual Private Line deliver Layer 2 service between two locations. EPL is a transparent port-to-port circuit. Whatever you tag at the edge is what shows up on the other end. EVPL hands off a service identifier per VLAN, which lets you carry multiple logical circuits over a single physical handoff.
Committed information rate sized to the build. Jumbo frames where the workload calls for it. MEF-aligned service definitions so a network architect coming from another carrier sees the same vocabulary. Single-tag or QinQ VLAN handling agreed in writing before turn-up.
DWDM lambdas at 10G, 100G, and 400G
A wavelength service hands you a dedicated lambda across our DWDM plant. You light both ends with optics you choose, and the wave between them belongs to you. No shared switching in the path. Only fiber and optics.
Picked by carriers extending their own backbones, by large enterprises that want to run their own Layer 2 over the top, and by financial-services and trading workloads where every microsecond saved on the optical path matters. 10G, 100G, and 400G lambdas where the build supports them.
VPLS and EVP-LAN across three or more sites
When the network has more than two sites talking, point-to-point stops being the right answer. Multipoint Ethernet, delivered as VPLS or EVP-LAN, gives you a single broadcast domain shared between every site on the service. Same VLAN, same MAC table, same Layer 2 reach across cabinets in different facilities.
Used when teams want their colocation cabinets, branch sites, and remote facilities to look like one extended LAN. MAC learning is controlled, the service identifier is consistent across sites, and the engineering team behind it is the same one that runs the underlying transport.
Licensed-spectrum radio between buildings
A point-to-point radio link on licensed spectrum, between buildings with a clear line of sight. Useful where fiber does not yet reach the building, or where the fiber build needs more time than the workload can wait. Stands up in days once the path is qualified.
Also useful as a diverse second circuit on a building already served by fiber, since the radio path follows the air rather than the same conduit as the fiber. Same backbone behind the radio, with the customer-edge handoff agreed in writing before turn-up.
Pick the shape that fits the build
One tile per category. If the build needs more than one, we will quote them together.
EPL and EVPL between two sites. MEF-aligned service definitions, committed information rate, jumbo frames, single-tag or QinQ VLAN handling.
DWDM lambdas at 10G, 100G, and 400G. Your own optical layer for carrier, large enterprise, and latency-sensitive workloads.
VPLS and EVP-LAN across three or more sites. One broadcast domain shared between cabinets and locations, with controlled MAC learning.
Licensed-spectrum radio between buildings on a clear line of sight. Last-mile when fiber does not yet reach, or a diverse second circuit on a fiber-served building.
Three quick questions
The ones we get on the first call. If yours is not here, the answer is on the other end of the phone.
When does a Wavelength make sense over Ethernet?
When you want your own optical layer. A DWDM lambda gives you a transparent pipe at line rate. You light both ends with optics of your choice, and the wave between them belongs to you alone. Carriers, large enterprises, and latency-sensitive workloads pick this over Ethernet because there is no shared switching plane in the path, only fiber and optics.
What about jumbo frames and VLAN handling?
Jumbo frames are supported on Ethernet services up to the MTU the platform allows. VLAN handling depends on the service type. EPL is a transparent port-to-port circuit and carries whatever you tag at the edge, including QinQ. EVPL hands off a service identifier per VLAN, so you can deliver multiple logical circuits over a single physical handoff. Both are agreed in writing before turn-up.
How far can the circuit reach?
Across Southeast Michigan, on our own fiber, anywhere our network already lights. Off-net extension is available where a partner backbone carries the path further, with the operational responsibility split clearly in the contract. The proposal will show which segments we operate and which sit on a partner.
Tell us the sites, we will quote the layer
Endpoints, capacity, service type, VLAN handling. We will tell you whether the path is on-net, where any off-net extension lands, and what the realistic turn-up window looks like.
