Turk Telekom taps ZTE for metronet upgrade

ZTE has upgraded Turk Telekom’s core sites of the operator’s 100G and B100G metro optical transport network in Istanbul, to improve the system capacity of the core nodes and the service access capability at its edge nodes. ZTE has provided the operator with 200G and 400G wave channels to increase bandwidth for current and future 5G network traffic, and the WASON (WDM  Automatic Switch Optical Network)  security mechanism to guarantee the network reliability.

ZTE proposes a new 100G/B100G dual-plane solution based on the original metro WDM network. Its industry-leading SDO (Software-defined optics) allows flexible selection of 100G/200G/400G rates and PM-QPSK/8QAM/16QAM modulation modes without changing hardware configurations, to offer the largest system capacity along with the longest transmission distance. This technology delivers sufficient bandwidth for service growth while improving service deployment flexibility and protecting the customer’s prior investment.

Along with the full-mesh architecture, ZTE is also providing a ROADM solution based on CDC-F (Colorless, Directionless, Contentionless, Flexgrid), supporting the upgrade to higher single-wavelength rates to meet new service demands. In addition, the WASON security mechanism enables automatic service recovery to raise network reliability, reduce CAPEX and protect customer’s investment in case of multiple fibre breaks without installing additional boards.

ZTE says the existing metro WDM network bandwidth cannot satisfy the rising new service demands of Turk Telekom, which is particularly urgent in Istanbul, the country’s largest and most densely populated city. Turk Telekom, therefore, decided to expand the system capacity of its metro optical network.
