How long does it take to install a fiberoptic connection at my location?

The installation time depends on the location and its distance to the fiberoptic connection. If the location is within the fiberoptic ring, then the installation takes about three days. The farther away the location is, the longer it takes, with times of up to 6 to 14 weeks.

Why is SysEleven’s fiberoptic connection better than other types of connection?

Fiberoptic lines use light in varying wavelengths. Thus they achieve far faster throughput.

How many Mbit/s are actually possible with a fiberoptic connection?

Connections start at 100 Mbit/s up to 10 Gbit/s depending on how much you order with a guaranteed availability of 99.5%, and up to 99.9% upon request. Connected locations can freely scale upwards as you need.

Is the bandwidth throttled or is there a volume limit?

No. Throttles belong in cars, not in bandwidths.

Are the upload and download speeds symmetrical?

Yes, we only offer symmetric connections. Upstream and downstream speeds are identical.

What hardware can I use with the fiberoptic connection?

Our clients have a free hand in choosing what devices they want to connect.
