PRODUCT UPDATE
OFS expands long haul range with 125 square-micron fibre
OFS has expanded its portfolio of long haul products with the introduction of TeraWave SCUBA 125 optical fibre, which has been designed for coherent transport submarine systems. The fibre’s effective area of 125 square-
microns means that nonlinearities are reduced, enabling the launch of higher signal power compared to G.652 and most G.654B fibres. The low attenuation of <0.158 dB/km (average) reduces signal loss. Together, these enable the launch of higher signal power into the span and reduce amplifier noise, enabling higher transmission speeds with more wavelengths over trans-Atlantic distances. It benefits from ultra-low polarisation mode dispersion (PMD), and resistance to mechanical stress. It is fully compliant with the ITU G.654.B, D and E standard for cut-off-shifted fibre. The ultra-low attenuation enabled by a pure silica core and large effective area mean that margin is improved beyond that needed for transmitting 100Gb/s over trans-Atlantic distances, across the C- and L-bands. The additional margin can

be used to support denser signal constellations than can be achieved with G.652 fibres for increased spectral efficiency. The new fibre complements the TeraWave SCUBA 150 fibre, which was launched in 2016, and it is purposely designed to match the effective area and mode field of the TeraWave ULL terrestrial optical fibre for ultralong haul connections between cloud data centres. This provides flexibility of linking submarine and terrestrial systems in the global cloud network.

Sedona Systems’ new Hierarchical Network Controller product is designed to automatically discover, provision and optimise L0-L3 services across multilayer, multivendor, multi-domain networks, affording providers next generation software-defined networks, as well as automated service creation and assurance. It is ‘hierarchical’ because it exists at the top level of the network control layer, above domain controllers from packet and transport vendors. It presents a single interface and simplified view of the network to service orchestrators and OSS products, and provides end-end network control and policy management by interacting with domain controllers from multiple IP and transport vendors. This results in a service-aware network that is able to provision and assure, based on the unique needs of each.
In initial implementations, service providers are using the NetFusion product as a single ‘pane of glass’ for provisioning L0-3 services, without having to configure every layer, domain and vendor separately, and allowing services to be provisioned in minutes.
