Solutions.

Microduct conduit can be an economical solution for reducing network building, construction and reinstallation costs. Microducts and micro-cabling offer an alternative and less expensive option to rebuild, enhance and improve data pathways for increased data demand.

Microduct Solution- Why?

​

Installed empty microducts.

​

  • As per normal cable or ducting with multiple spare tubes.

  • Tubes sealed until used for future expansion.

 

Configure microduct pathway.

​

  • Connect tubes at tube distribution points.

  • Point to point pathway achievable through tube connectors.

 

Deploy blown Fiber unit or cable on demand.

​

  • Blow fiber unit/cable point to point.

  • No need to splice along route.

 

Low Initial cost both material and Installation cost.

 

The network can grow on demand.

 

Easy to install microduct routes in occupied ducts.

 

Faster installation and roll out of networks.

 

Up to 144 fibers can presently be deployed in one microduct.

Past mistakes during first roll-out of microduct.

 

No tracer wire installed.

 

Thin microduct tube.

 

Every 8km maintenance loop were installed.

 

Microduct / Micro cable – is at it’s infancy then without strength member, today much

developed and improved.

 

Quality of Testing of Materials needed.

 

  • Previous pipe used has a pre-lubricant jelly inside the duct which needed to be flushed out, cleaned before cable installation.

  • Connectors / Plugs used has only 10 bar rating , it should be 16  bar

 

Microduct Installation    - it should be straight and smooth flowing as possible. Roller coaster installation increases friction. Specially abrupt bends ( common in E/E pits )

 

Manholes / open trench installation – need careful supervision and inspection after every span, since likelihood of wrong laying and handhole termination/ jointing pits practices could occur like, straightness, and sand encasement (cases happen when big boulders, rocks are shoved into the trench, damaging the ducts. There are cases too that growing trees and roots squeezes the ducts.)

 

Proactive Repair Team Readiness :

​

  • Every OSP Contractor should be trained in this technology, and invest in the specialized tooling/ equipment needed.

  • Training program is essential to this deployment’s success.

  • Dedicated maintenance contractor specializing in microduct technology.

 

Quality Control.

  • Should include  continuity of tracer wire. Tracer wire test.

  • Ball bearing test should be very strict.

  • End cap plugs.

  • Every 250m manhole with 25-30m maintenance loop.
