More About
FIBER.BG operates as a telecommunications carrier and network infrastructure provider in Bulgaria, with a focus on fiber-optic connectivity and IP-based services for enterprises, carriers, and end users.
The company’s core offering centers on fiber-optic internet access for both residential and business segments, typically delivered over Passive Optical Network (PON) or point-to-point Ethernet architectures common in Fiber-to-the-Home (FTTH) and fiber-to-the-building (FTTB) deployments.
For corporate and institutional customers, FIBER.BG provides dedicated data links, point-to-point and point-to-multipoint connectivity, and leased line services that support use cases such as interconnecting branch offices, data centers, and cloud access gateways.
These services are usually delivered over Ethernet and IP/MPLS (networking) technologies, with Quality of Service (QoS) configurations that allow enterprises to support voice, video, and critical data applications.
In addition to retail connectivity, FIBER.BG functions as a regional carrier and wholesale provider, offering capacity and backhaul services to other Internet Service Providers (ISP), content providers, and telecommunications operators.
This places the company in the wholesale telecom and carrier-neutral infrastructure segment, where it contributes fiber routes, metro rings, and long-haul links that integrate into broader national and cross-border network topologies.
The company’s infrastructure services include planning, building, and maintaining fiber networks, including last-mile connections, backbone segments, and POP-to-POP links, often used by enterprises for secure Wide Area Network (WAN) connectivity and by service providers for expanding coverage footprints.
Its IP-based service portfolio typically covers routing, switching, and network management functions aligned with common internet and carrier standards, including Border Gateway Protocol (BGP) for external routing, VLAN-based segmentation, and standard Ethernet handoffs for customer equipment.
Within an enterprise IT and telecom marketplace taxonomy, FIBER.BG fits primarily into fixed broadband connectivity, carrier Ethernet, wholesale transport, and managed network services categories, serving as an access and transport layer provider that underpins higher-level services such as cloud, collaboration, and security platforms operated by its customers or their partners.
