Transmode announces standards-based coherent 100G strategy for metro and regional networks

Stockholm – 13th September 2011 – Transmode, a global supplier of packet optical networking solutions, today announced the company’s strategy for 100G optical networking solutions based on coherent technology that specifically addresses the challenges faced by network operators planning 100G deployments in metro and regional networks.

“We set ourselves the challenge of rethinking 100G from a metro and regional perspective,” said Karl Thedéen, Transmode’s CEO. “We needed to ensure that the approach we took to 100G integration was the best for our existing customer base and was very attractive to prospective customers. These networks require a standards based, cost effective and compact solution that works on existing infrastructure including advanced ROADM-based networks. Customers also require a simple pay as you grow approach to adding 100G.”

The Transmode 100G Metro solution uses standard PM-QPSK optics with coherent detection to provide 100Gbit/s on a single wavelength and up to 10x the capacity of today’s 10G systems, which is significantly more than some alternative non-standard modulation formats. It also introduces stackable capabilities to the TM-Series which provides customers with a pay-as-you-grow approach to their 100G investments. Furthermore, it includes a new 100G plug-in unit that is fully integrated with the widely deployed TM-Series. The 100G plug-in unit has a common host-board and application specific plug-in daughter-boards on the client side that can configure the unit as a transponder, muxponder or regenerator. This greatly simplifies network design, ordering, deployment and spare part management and also allows easy upgrades to additional configurations in the future.

“The optical networking industry is rapidly moving towards 100G solutions for high capacity networking options, although the vast majority of these solutions and initial deployments are primarily targeted towards core network applications,” said Andrew Schmitt, Directing Analyst, Optical at Infonetics Research. “We predict that these core networks will quickly move to predominantly 100G once the technology reaches the right price points. However, we also predict that metro and regional networks will gradually migrate to a 10G/40G/100G mix, creating a totally different set of challenges for the network operators”.

“To optimize price/performance for the metro and regional markets, our approach has been to focus on standard 100G optical technology and a solution for distances up to 750 km. In parallel, we will also provide a version for distances up to 1500 km based on the same technology to cover the wider market,” said Sten Nordell, Transmode’s CTO. “Our approach allows us to create a solution that provides investment protection for existing customers and is cost effective when adding anything from a small number of 100G wavelengths to existing 10G/40G networks right up to a fully loaded 100G system that enables 8 Tbit/s of traffic on a fiber pair. In addition, the solution is highly compact and uses only 75% of the space required for the current generation of 100G systems. All of which make this solution ideally focused on metro and regional applications.”

Customer trials of the new solution commence at the start of 2012 with network deployments from the middle of 2012.
