Optical

A wavelength is the closest thing to your own fibre without buying the fibre

A dedicated channel on our optical line system between two European sites. No shared packet layer, no contention, and a latency figure that depends on nothing but the route the fibre actually takes.

The channel

Nothing else touches it in between

You hand us a client interface at each end, we carry it as a dedicated channel across our optical layer. There is no packet layer to share - nothing to contend with, no queue to sit behind on a busy evening.

The line system

Engineered rather than ordered

Channel plans, launch levels and the design margin are ours to specify on the corridors we light, and we hold capacity there rather than buying a circuit each time somebody asks. So a wavelength on a route we already run is a provisioning task, not a construction project.

Quoted from the fibre, not from a map

A straight line between two cities is a number anybody can produce and nobody can deliver. We quote the round trip the route actually has - written into the order - and if a shorter path exists we will tell you what moving onto it costs.

Alien waves

Bring your own transponders

If you would rather own the optics end to end, we do the engineering to confirm the route budget supports it and hand you the channel - your transponders, your modulation, our line system.

Optical detail

Client interfaces
10GBASE-LR, 100GBASE-LR4, 400G LR4, ZR and ZR+ subject to reach.
Line system
Amplified DWDM with the channel plan, launch levels and design margin specified by us on the corridors we light.
Channel spacing
100 GHz fixed grid as standard, flex grid on selected corridors.
Protection
1+1 optical protection where two physically diverse routes exist between the endpoints; unprotected where they do not, stated plainly rather than implied.
Monitoring
Per-channel optical power and pre-FEC BER, visible to you rather than only to us.
Latency
Quoted per route from the measured fibre length, with the figure written into the order rather than into the brochure.
Handoff
Single-mode LC in your rack or ours; cross connect arranged by us.
Alien wavelengths
Supported. We confirm the route budget, agree the channel and hand it over; your transponders, your optics.

Corridors we already light

Wavelengths are available between any pair of our sites. The spans below are lit today and can normally be delivered fastest.

What runs over them

In combination

What a wavelength usually arrives with

A lambda is the bottom layer. The layers above it are the same order form.

Layer 2

EVPN-MPLS when a whole wave is too much

Need the transparency but not 100G of it? The same corridors carry E-Line and E-LAN circuits at 1G-400G, protected where the route is diverse - and you can move up to a wavelength later without changing cities. EVPN-MPLS transport →

IP transit

Light the wave, buy the internet beside it

DC interconnect on the lambda, transit on the same handoff at either end - one cross connect, both services, and every prefix behind the DDoS filter from turn-up. Protected IP transit →

Frequently asked

Is the wavelength protected?

1+1 optical protection where two physically diverse routes exist between the endpoints. Where they do not, we say so before you order - stated plainly rather than implied - and you decide whether your equipment handles failover instead.

Can I bring my own transponders?

Yes - alien wavelengths are supported. We confirm the route budget carries your modulation, agree the channel, and hand it over: your optics, our amplified line system.

Is the latency figure guaranteed?

It is quoted from the measured fibre of the actual route and written into the order - not estimated from a map. If a shorter path exists, we tell you what moving onto it costs.

What speeds can I hand off?

10G, 100G and 400G client interfaces - 10GBASE-LR, 100GBASE-LR4, 400G LR4, and ZR/ZR+ subject to reach.

How fast can a wave be delivered?

On a corridor we already light, it is a provisioning task measured in days. A new corridor is an engineering conversation first - we will tell you which of the two you are asking for.
