2 Cabling system using fiber optic microcables, microduct conduits and air blowing (jeeting) system All standard components (cables,ducts, subducts) diameter are reduced to allow more network flexibility and versatility Deployed in underground cable duct aplications including sewer, railway, highway and others with with Specially designed for fiber optic systems large capacity of fibre count and networks several distributions points. Example: (Metropolitan PON, FTTH,

3 Lower intial capital investment and boost revenue Fibres can be deployed as needed basis along with traffic and subscribers Minimized upfront capital expanditure Microduct networks are future proofing -Unused microducts are available for later fiber/cables upgrade Ability to upgrade add latest technology /fibre types Scalability and phased implementation Maximum and scalable connections number per duct Minimal number of distributions points and splices

4 Several methods of installations Microducts can be installed into old ducts pipes to increase their capacity Allowed installation s method are: by pulling bundle of microducts by jetting bundle of microducts using pre-manufactured pipes with microducts Quick and smooth installation Microcables installations are supported by jetting method, reducing the risk of damage of cable and increasing installations distance of cable blowing Pulling Jetting

5 Traditional construction consists of Main duct and sub-ducts Main duct PVC with typical ODs from mm Sub-ducts HDPE with typical ODs from mm 1 sub-duct hole= 1 cable installed New MetroJET system allow for dividing the sub-ducts 8/10 mm micro-ducts can be installed into existing ducts Optimised for blown cable applications Can make better use of existing duct structure New microducts in existing ducts will increase count of holes in main ducts 1 sub-duct hole= up to 3/5/7/10 cables =!!!!!
