Building of Fibre Optic Networks

As operators of communication networks become competitive and technology changes, Companies require to become technologically driven and have to meet rapid changing standards in optic fibre installation. DNA remains in the forefront of this technology which needs to be passed down to technical staff within the organization. Our Directors are trained in every aspect of these new technologies which then enables organization to pass on all skills to their technical staff and implementation teams.

Our optical specialists include: CFOT certified (Certified Fibre Optic Technicians), trained to international standards to provide delivery to the South-African Market. We also provide consultancy to design and implement fibre optic back bone projects and have all the equipment available in house to deliver and complete these projects.

.

Benefits

The benefit of CD –PMD testing includes :

• PMD and CD measurements for all types of networks
• Standards-compliant approach delivering . rst-time-right results
• Fully automated, highly intelligent interface
• One test solution for all dispersion testing—for reduced CAPEX
• Single-ended testing of multiple links from one location for fewer truck rolls and reduced OPEX.
• Lower maintenance issues due to higher quality network link.

Fibre Optic Splicing and Testing

• Splicing: Splicing into current infrastructure or splicing the allocated
pairs to the client or site, and labelling and maintenance
• Fibre optic link testing: Testing between access, switching,
aggregation/core nodes to ensure links are operational with minimum
losses and maximum bandwidth available. The most technically
advanced equipment is used for OTDR traces by means of
EXFO FTB200 OTDR complete with maxtesters for light source and
power meter
• Acceptance testing (Cromatic Dispersion and Polarised Mode Dispersion) by means of EXFO FTB500 OTDR complete with maxtesters for light source and power meter; and
• Field splicing by means of a combination of the Fugikura 60S and
Sumitomo T39
• As-Build Documentation includes records and reports of all the
actions, findings, implementations and results
• Quality Assurance according to client, product and international
standards.

FTTx Solutions

• Fibre-to-the-home (FTTH) Our solution reaches the boundary of the
residential home, ina box or on the outside wall of a home.
• Fibre-to-the-building or basement (FTTB) We lay the fibre link to the
boundary of a building with the final connection to the individual small
business or living unit being made with other means.
• Fibre-to-the-node (FTTN) The fibre runs to and terminates in a box in
the street several kilometres away from customer premises with the
final connection being copper.Fibre Optic Splicing and Testing.
