Private Ethernet Lines
Securely interconnect LAN networks across different locations with direct fiber lines

Private Ethernet Lines integrate LAN networks of your offices and branches across different locations using a high-speed fiber network that operates independently of the Internet. This allows servers, computers and other devices from different locations to establish long-distance direct connections with guaranteed bandwidth.

You can connect two locations using a single line or multiple locations to create a network. Multiple technologies are supported, such as Ethernet Private Line, Ethernet Virtual Private Line, Ethernet Private LAN, Ethernet Virtual Private LAN, Ethernet over MPLS and Ethernet over SDH/SONET.


  • Guaranteed bandwidth and very low latency between long-distance locations, which is very important for real time applications.
  • Private communication because packets travel outside the Internet.
  • Easy to maintain and migrate since no public IP addresses are involved.
  • Lines terminate at Ethernet interfaces, enabling easy integration with your switching and routing devices.
  • Ethernet as underlying protocol, allowing you to run your own network technologies on top of it, like VPN and custom QoS policies.

Interspace Network

Interspace has its own regional network that operates in a redundant topology, with two larger rings connecting Macedonia - Bulgaria - Serbia - Slovenia - Croatia - Bosnia - Montenegro - Kosovo - Macedonia and Macedonia - Greece - Bulgaria - Macedonia. We have three major points with routing equipment outside of Macedonia in data centers in Belgrade, Sofia, and Athens. 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 the lowest latency and the highest quality for traffic flow.

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

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 by extensive OTDR, RFC 2544 and ITU Y.1564 measurements to guarantee the best transmission quality.

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.
