TONY PEARSON LUMENISITY Q&A
Does it require non-standard connectors e.g., for connecting to transceivers, patch panels etc
dispersion and can be operated over a broader wavelength range e.g., O, C & L bands. This increases system reach and data carrying capacity. Also, CoreSmart cables are field-splice capable allowing multiple cable segments to be jointed and deployed in challenging outdoor environments to service longer route length networking applications. In addition, they are compatible with SMF and equipment, such as optical amplifiers, this greatly extends the reach and number of possible network applications. The performance of our hollowcore technologies has been evaluated by independent parties, including carriers and equipment providers and typically shows 100x longer reach with 40x the data-rate over other types of hollowcore fibre.
this is true in all applications. This saves overall cost and gives flexibility in access, for example to power utility. Multi- channel, multi-terabit transport has been demonstrated over several thousands of kilometres using commercially available transmission equipment. We expect significant advantages for applications such as HFT, 5G networks and enabling increased geographic expansion in DCIs, that benefit from the much lower latency than solid core fibres and other types of hollowcore that are route distance and bandwidth limited. There have been several successful transmission trials with CoreSmart hollowcore fibre. BT labs showed error-free transmission with 38 DWDM channels over 10km of field-deployable CoreSmart cable using 400ZR pluggable transceivers. Lumenisity and Ciena completed DCI transmission trials using Ciena’s WaveLogic 5 Extreme (WL5e) and Wavelogic 5 Nano (WL5n) commercial systems and achieved a capacity of 38.4Tbps with 48 x 800Gbps channels over greater than 20.5km of CoreSmart cable, without in line amplification. Characterization testing was also carried out on CoreSmart cable in a recirculating loop, achieving over 1000km reach across the C band with 45x 400Gbps WL5e channels.
TP CoreSmart solutions can be jointed to conventional SMF, so existing termination equipment such as transceivers and connectors can also be used.
Can hollowcore fibre be used in conjunction with conventional fibre on the same network? CoreSmart cable can be used in conjunction with conventional SMF over the same network. It is
fully backward compatible with existing networks and systems and can be fusion spliced in the field and can be jointed to other types of SMF equipment, such as optical amplifiers, splitters and multiplexers.
What is the roadmap for further development?
We are constructing our own dedicated fibre fabrication facility in Romsey, Hampshire, UK. CoreSmart
Other companies have been developing hollowcore fibre, so what is different about
cable has the potential to re-write the network design rule-book. We are developing future generations of CoreSmart solutions with lower attenuation to extend the reach and increase the capacity beyond that of conventional solid core fibre optic cable today.
TP Compared to other hollowcore fibre, such as Photonic Band Gap Fibre (PBGF), our NANF based CoreSmart has lower attenuation, lower
