The Need for Speed
How Can We Build Denser Networks Faster!!
Denser Urban Deployments
• Micro-trenched green field installs
Denser Faster
• Augmentation of existing duct spaces
Service Segregation
• Multi-way ducts
• Reduced risk to service continuity
Challenges?
• MLT designs – longer splice time
• Specialized equipment Micro Cable Technology Blow Installation

Why Micro-LITE 200μm NextGen Micro Solution
› 432 fibers in 8.8 mm diameter cable › Ease of future capacity expansion
High fiber density
Smaller dia
› Existing 2” duct retrofit option #1 - (864f + 2 x 432f) = 1,728 fibers
›
›
Individual fibers are more accessible when adding new
Existing 2” duct retrofit option #2 - (5 x 432f) = 2,160 fibers customers or services
› Greenfield ~ 2” 7-way micro-duct (7 x 432f) = 3,024 fibers
Sub-unitized design
Greater duct capacity
› 1.5 km for greenfield duct (14/18 mm) › F1 – F2 separation
› Troubleshooting/Isolation
Greater blow distance › Easier segregation of services
Easy to repair

432 Micro Cable Blow Test Results
Speed (m/min)
Blow Distance (m)
› 18/14 mm microduct
› 432 microcable with PE jacket blew 1500+ Meters (0.93 miles)
› PA Jacket extends blow distance to about 1900 meters (1.2 miles)
› Enables single shot installation of significant cable length

Faster – Blow vs Pull Installation
Faster deployments with
Micro Cables blown into UG ducts
Parameters Cable Pulling Cable Blowing
Machine Setup time 10 mins 30 mins
Required Manpower 3 to 8 3
Typical Installation Length upto 250 m 2 kms in a single blow
Cable distance pulled for 1 km installation 2500 m 1000 m
Cable pulling/ blowing length per minute ~20 m/min 60-90 m/min
Time taken to install 1 km cable ~3 hours ~ 30 min
Steps involved in
• Pulling manhole every 250m pulling cable C9 C8 C7 C6
• For 1 km install cable is
pulled for 2.5km
