Managed Dark Fiber represents a rental of optical fibers between two distant locations, backed by 24/7 maintenance of the cable infrastructure. The link terminates on passive fiber termination boxes, allowing you to use your own laser light equipment for data transmission.

This service gives you autonomy over the connection quality and capacity. Moreover, it significantly reduces the risk of data breaches, as the signals do not travel through our active network equipment.

1.Robust and Redundant network

Our network architecture is designed to serve mission-critical and business-critical systems, ensuring maximum transfer rate, low latency and multi-level redundancy for highest level of service quality. The network is connected to the leading global and regional tier1/tier2 networks, over protected and geographically independent fiber lines.

1.1.Local Network

Interspace operates its own fiber optic network in Macedonia, spanning over 1500 kilometers. The network includes fiber routes to nearly all cities and border crossings in Macedonia. Within cities, we have the most extensive presence in Skopje, covering all districts.

The core network features terabit capacity for switching and throughput. Every user-side port has dedicated throughput capacity because every single L2/L3 device in our network (models verified by Tolly and Miercom testing) provides line-rate non-blocking forwarding capability. This means they can process maximum bandwidth for all frame sizes (64-1518) on all ports simultaneously.

1.2.Regional Network

On a regional level, Interspace operates a network with a total length of around 2000 km. It functions in a redundant topology with two major rings on the following routes:

1. Macedonia - Bulgaria - Serbia - Slovenia - Croatia - Bosnia - Montenegro - Kosovo - Macedonia
2. Macedonia - Greece - Bulgaria - Macedonia

We have several major Points of Presence with high-capacity routing equipment for telecommunication services, including:

1. Macedonia: Located in Interspace data centers in Skopje and Deve Bair.
2. Bulgaria: Located in a top-class independent data center.
3. Serbia: Located in a top-class independent data center.
4. Greece: Located in a top-class independent data center.

Through this network, we connect directly to other providers at their nearest point in the region. The connection is made through multiple geo-independent super-fast links based on DWDM technology, which enables lowest latency and highest quality traffic flow.

1.3.Global Presence

For our cloud and online video platform, Interspace has an IT infrastructure in the following regions:

1. Europe: Germany, Netherlands, France, United Kingdom, Austria, Macedonia, Serbia, Bulgaria, Greece.
2. North America: USA, Canada.
3. Asia/Oceania: Australia, Japan, Singapore.

2.First-Class Fiber Infrastructure

Interspace's fiber network is designed according to all relevant ISO standards and constructed by following strict procedures, ensuring compliance with the highest quality requirements. We hold the highest accreditation for network infrastructure design, the A-grade license, attesting to our capability to design high-grade fiber optic networks.

We have our own teams and equipment for the entire process of constructing, operating and maintaining the network. We employ fusion splicing instead of mechanical splicing of the fibers, ensuring long-term durability and reliability. The link quality is verified through extensive OTDR, RFC 2544 and ITU Y.1564 measurements to guarantee the best transmission.

We conduct continuous 24/7 proactive monitoring on every segment of the infrastructure. At the root level, we reserve two fibers in each cable for measuring the general cable condition. We monitor multiple components, such as power supplies, temperature, and traffic, in every network device, including constant verification of optical power levels at each end-point interface. This allows us to act quickly and flawlessly, ensuring the guaranteed SLA and connection uptime.
