Prysmian Group and Finisar Demonstrate 300-meter 100 Gbps SWDM Transmission over WideCap-OM4

Milan, 29th September, 2015 - Prysmian Group, world leader in the energy and telecom cable systems industry, demonstrates 100 Gbps shortwave wavelength division multiplexing (SWDM) transmission over 300m of WideBand multimode fiber, WideCap-OM4, commercially available since ECOC 2014.

Multimode systems based on OM4 and VCSEL technology provide a low cost and power efficient solution for 100 Gbps data center networks based on parallel multimode fibers. The IEEE recently standardized these systems as 100GBASE-SR4, providing a maximum reach of 100m on four parallel OM4 fibers. There is significant effort in the industry to increase the capacity of multimode fibers (MMFs). One such activity is to develop WideBand MMFs capable of SWDM transmission using high speed VCSELs between 850nm to 950nm.

Prysmian and Finisar demonstrate that extended reach, fiber efficiency, and low power can all be achieved simultaneously by a combination of 4 x 25.8 Gbps SWDM VCSEL technology and WideCap-OM4. 100 Gbps SWDM transmission over 300m was achieved utilizing conventional low-power NRZ electronics, SWDM optics and WideCap-OM4.

The unique advantages of SWDM technology allow users to leverage their installed duplex MMF at 40 or 100 Gbps, using four VCSELs operating at different wavelengths multiplexed onto a single strand of MMF, thereby requiring only one transmit fiber and one receive fiber. This provides the ability to easily migrate from 10 to 40 or 100 Gbps over the same long reaches of duplex MMF previously used for 10 Gbps.

'WideCap-OM4 provides OM4 performance within the 850nm to 950nm wavelength range, allowing data center owners to take full advantage of SWDM transceivers based on duplex LC connectivity. WideCap-OM4 offers 4700MHz.km bandwidth at 850nm for compatibility with IEEE 850nm-VCSEL based applications such as 10GBASE-SR, 40GBASE-SR4 and 100GBASE-SR4 while securing high bandwidth at wavelengths up to 950nm for optimum performance with SWDM optics' indicates Andreas Wassmuth, Director Telecom R&D with Prysmian Group. 'WideCap-OM4 is future-ready and offers the greatest flexibility for data center networks', adds Adrian Amezcua, MMF Product Line Manager with Prysmian Group.

Prysmian Group will be one of the main participants of ECOC 2015, with 7 presentations about innovations in next generation optical fibers including WideCap-OM4 and SWDM technology, and exciting results on space division multiplexing and few mode fibers in access and long-haul optical networks.

Join Prysmian and Finisar as they present their findings at the ECOC 2015 technical conference in Valencia, Spain, on Tuesday September 29th.
