Todays presentation focus on our 432 fibre cable designs – considered an ‘entry-level’

WTC (wrapping tube cable) comparison analysis

Scope:

To review the Total Cost of Ownership (TCO) benefits of Fujikura’s ultra-high-density

Wrapping Tube Cables (WTC) and innovative Spider Web Ribbon (SWR) fibre

technology compared to traditional Loose Tube designs.

Space Efficiency

Alternative Industry Designs

Cable Strike

• Significantly reduced outage time

• Urgent circuits restored quickly

Typical restoration time in hours:

432 Fibre WTC/SWR 4-5

432 Fibre LT Duct 16-20

Significant Operational Savings

ANALYSIS - General Assumptions

• Cable sections typically 2km between joints

• Industry standard joint at both ends

• Installed within sub-duct 20mm (internal diameter)

To demonstrate the benefits of WTC/SWR, we For illustration purposes we have outlined a number of scenarios;

1. 432F WTC to 432F WTC

2. 432F Loose Tube to 432F Loose Tube (conventional design)

3. 432F WTC to 432F Loose Tube x3 144F LT using ribbon splicing

Estimated Splicing Time Comparison

Dramatic splicing time reduction

Splice Loss

• Total Splices: 432 SWR’s (5,184 individual fibres)

• Environment: Field Conditions

• Average splice loss <0.02dB @ 1550nm

• Average link loss <0.19dB/km @ 1550nm

• Rework <5% fibre (total ribbons)

• No multiple reworks

• Predicted 70R splice loss results consistent with OTDR bi-directional measurements

Fibre management of WTC/SWR in closure

Compatible with industry standard joint closures

WTC Fibre ODF

ODF is designed for use in a Building Entrance Solution for high fibre count Wrapping Tube Cables® (WTC), providing a demarcation point between OSP and ISP cables.

Significant operation benefits

• Small diameter and light weight

• Clean dry cable design (no water blocking gel)

• Manufactured in long lengths for versatility in deployment

• Suitable for mass fusion splicing

Significant cost savings

• 75% overall installation time saving (432F WTC-WTC)

• 35% improved duct efficiency (432F WTC versus 432F LT Duct)

• Substantial operational savings

• Deferred costs (significant)
