Optical transmission technologies for
high-capacity and high-performance networks

Routing and switching technologies form the core of every network infrastructure, but it is the deeper network layers that ensure that services reach the end customer! Based on innovative Wavelength-Division Multiplexing (WDM) solutions, optical networks offer the necessary capacities and transmission rates for the reliable transport of today’s and tomorrow’s data volumes.

With many years of expertise and comprehensive know-how, our engineers in the area of optical transport/transmission implement flexible, complex optical networks with transmission rates of up to 800 Gbit/s per channel with up to 96 channels over a single fiber pair – whether in access, metro or backbone/longhaul networks.

Optical Transport – Solutions Portfolio

Data Center Interconnect

Direct optical interconnects for distances from 10 km to over 1000 km and use of multiple terabits/s on the same fiber infrastructure

Ultra-Low-Latency Connectivity

Achieve highest quality for e.g. cloud computing, video streaming or securing critical communication like trading applications

Carrier-class WDM and OTN

Increasing the capacity of optical networks with technologies for wavelengths of 400G/s and higher and additional flexibility with multi-degree ROADMs (FlexGrid)

FTTx and Active Ethernet

Connection of end users and business customers via passive (xPON) or active (Ethernet) infrastructures and provision of IP services such as Internet, TV and landline and mobile telephony

Packet Optical Transport / Carrier Ethernet

Flexible metro and metro-access networks and realize competitive and new business services

Mobile Front/Backhaul Connectivity

Increase of network performance, quality and cost efficiency for new services


100G DWDM optics in QSFP28 format (PAM4) for cost-effective point-to-point connectivity with a total capacity of 4 Tb/s


Use of dedicated crypto modules for encryption and protection/securing of data on the physical layer of transmission networks

Open Line System (OLS)

The next evolutionary step of optical networks: an optical transmission layer in a fully automated 1U system for wavelengths and data rates of different vendors and DWDM systems


Agile, flexible networks (SDN/NFV) through automatic (re-)configuration of the transmission network due to e.g. path interruption, bandwidth bottlenecks and when setting up connections

Optical Transport – dedicated services


After receiving the systems, Xantaro takes over the testing and pre-configuration of the hardware according to customer requirements before delivery or rather the start of the rollout. The benefits for your project:

  • Early identification and replacement of DOA components (dead-on-arrival) or delivery shortages
  • Planning security with reliable installation dates
  • Reduction of installation time on site due to pre-assembled chassis and pre-configuration

Fibre Characterisation

Xantaro takes on the measurement of highly critical and high-performance optical networks for the complete qualification of the fibre optics and an exact determination of the transmission properties of existing or new fibre optic infrastructures:

  • bidirectional measurement of the insertion loss
  • bidirectional OTDR measurements to determine the length and spatially resolved attenuation curve
  • measurement of return loss
  • measurement of chromatic dispersion (to derive compensation measures)
  • measurement of polarization mode dispersion for evaluation of physical disturbances and suitability starting from 40G/100G per wavelength
  • customized result report
