Telemach upgrades optical network flexibility with Transmode

Packet-optical transport systems supplier Transmode says it has supplied platforms to Slovenian cable MSO Telemach in support of the upgrade of the service provider’s fiber-optic networks between Ljubljana to Maribor and Vienna in Austria. The upgrade saw a static core/access infrastructure replaced with a more flexible and scalable architecture that will reduce operating expenses and long term service overheads, Transmode asserts.

Telemach, part of the United Group, provides a variety of cable TV, telephony, and broadband Internet services. The United Group, which operates several telcos in the Adriatic region, has selected Transmode as its primary provider of optical transport hardware.

The new network links Ljubljana with other major centers such as Maribor and Celje in Slovenia, and forms part of an international link to Graz and Vienna in Austria. It supports 10 Gbps services currently, with the ability to scale to 100 Gbps in the future.

"We wanted to both increase the capacity of our network and improve the ability to provision and deliver successful and innovative services to our customers,” explained Telemach CEO Marko Šter. “We chose Transmode because its team understood our needs and design requirements, and they have provided us with quality and simplicity in this WDM solution. The new network provides us with a technological advantage and means we are able to offer our customers the best possible service experience."

The new 80-channel optical network was built in parallel to Telemach's previous optical network simplify the switchover of customer services. Telemach needed to quickly decommission the old network in a controlled manner to switch over to Transmode's ROADM-based platforms, part of the company’s Flexible Optical Network portfolio that includes the TM-Series platform. Live traffic began to cross the network on August 27, less than a month after the equipment roll out began, Transmode says. In addition to the hardware, Transmode provided installation, training, and testing services.
