Andrew Schmitt, directing analyst for optical at Infonetics Research, said, 'In the third quarter of 2011, Infinera posted a revenue increase that moves them into first position in North America and third position worldwide for combined terrestrial long-haul WDM transport and ROADM equipment.
Other updates include software support for ROADM as well as support for the Sorrento management system, which enables more efficient interface capabilities to Oracle-based systems.
The debate between 40G and 100G in WDM networks is over, so for our latest 40G/100G and ROADM deployment strategies survey we focused on identifying how the rollout of 100G will take place and to what degree networks will migrate to coherent technology and ROADMs," explains Andrew Schmitt, principal analyst for optical at Infonetics Research.
0 Architecture and Design, Andre Fuetsch, said AT&T was tapping software control and open hardware to its reconfigurable optical add/drop multiplexer network switch, as well as launching the Open ROADM group in a move to promote vendor support for the technology.
Ericsson's Marconi MHL 3000 family, proposed in the ROADM solution for CHT, will significantly boost network speed and performance, enabling up to 80 channels with up to 40Gb/s capacity per channel.
Growth in the overall WDM ROADM equipment market hasn't been stellar, but it has far outstripped the declines seen in ROADM WSS units and revenue," explains Andrew Schmitt, principal analyst for optical at Infonetics Research.
Featuring a novel photonics architecture, it delivers the cost benefit of passive fixed-filter-based solutions as well as the flexibility of WSS ROADM.
Also, by mid-2011, Frontier will have added over 6,500 miles of ROADM network.
The NESC CDC ROADM network is based on a hybrid solution consisting of Cyan's Z-Series packet-optical transport system and CALIENT's new S320 3D MEMS photonic switch.
point-to-point, ring, ROADM spur), and helps service providers protect their investment by enabling seamless and non-disruptive upgrade to full ROADM capabilities without sacrificing footprint, power consumption, or cost-effectiveness.
