Fixed line network

The fixed network is based on DWDM transport consisting of 260 nodes on the backbone, including 190 nodes with automatic GMPLS protection / recovery. The maximum capacity of a single DWDM range is 34 TB.

With increased channel bandwidth and bandwidth, the DWDM network provides connectivity at 100G / 200G / 400G speeds, ultra-short latency times, and is also ready to carry 1TB channels. The network has automatic fault diagnosis (GPS coordinates) thanks to integrated OTDR components, which significantly reduce the time of possible troubleshooting.

There are more than 700 DWDM / CWDM access nodes that allow you to connect with end users in metropolitan networks and for the needs of B2B customers.

As part of the DWDM transmission network, international connections were opened to Frankfurt, Berlin, Prague, and Lviv, and DWDM access was provided to Poland’s main DataCenter.

The network has the ability to encrypt customer connections and implement virtual transport networks for other operators.

The IP layer is built on 8 backbones that provide Tier1 operators, XSP operators, IP traffic exchange points, content providers and points of contact with the Cloud infrastructure. The IP backbone network combines Carrier Ethernet traffic, B2C client traffic and its own CDN network for the purposes of IPTV services provided by Polsat Plus Group.

The Carrier Ethernet layer, based on IP MPLS technology, consists of 220 distribution routers connected to 100G switches and more than 2,500 input switches with 10G ports.

Internet access services for B2C customers are provided through an access network consisting of 1400 DSLAM access nodes (xDSL technology, SuperVector), two metropolitan areas of the HFC cable network (DOCSIS 3.x), about 10,000 access keys for ETTH access and 820 FTTH nodes. . .

Currently, Polsat Plus Group is in the process of modernizing our access network based on two main technologies based on fiber access: FTTH (Passive Optical Network) in GPON technology and FTTB (Fiber to the Home). , where the optical fiber is connected to each building and subscriber access is provided using Gigabit Ethernet technology. Together with the HFC DOCSIS 3.x cable network in Warsaw and Krakow, it allows to provide 1 Gb / s services to all customers in the range of these networks.

In 2021, Polsat Plus Group’s retail customers transferred 1.8 EB of data compared to 1.5 EB transmitted in 2020, an increase of 17% per year.
