FTTH Installation & Support

Fiber to the Home (FTTH) installation and support involve setting up high-speed fiber optic internet directly to a residential or commercial location. Tangent implements following  process:

Site Survey and Planning

• Site Survey: Technicians visit the location to assess the requirements, layout, and best approach for fiber installation. They look at factors such as the distance from the nearest fiber distribution point and any obstacles.
• Planning: Based on the survey, a plan is created to determine the route of the fiber cable, equipment needed, and potential challenges.

Fiber Cable Installation

• Trenching/Burial or Aerial Installation:
  • If underground, technicians dig trenches and lay conduits to protect the fiber cable. This could involve traditional trenching or newer micro-trenching methods.
  • If aerial, fiber cables are installed along existing utility poles.
• Home/Building Entry: Once at the location, the cable needs to be brought into the building or home.

Termination and Splicing

• Splicing: Fiber optic cables are spliced if necessary to connect them to existing infrastructure.
• Connector Installation: The fiber is terminated with connectors, typically at a wall-mounted box inside the home called an Optical Network Terminal (ONT).

Optical Network Terminal (ONT) Installation

• ONT Placement: The ONT, which is a small box converting the optical signal to an electrical signal for use in the home, is installed. It’s usually placed near where the fiber enters the home.
• Power and Backup: ONTs require power, so a nearby power outlet is necessary. 

Router Setup and Testing

• Router Connection: The ONT is connected to the router, allowing devices within the home to access the fiber internet.
• Configuration: Technicians configure the router and perform speed tests to ensure the connection is working at optimal speeds.
• Testing: Technicians test for latency, signal strength, and throughput to confirm the quality of the connection.

Customer Education and Initial Support

• Customer Orientation: Technicians typically explain the basics of the FTTH setup, how to connect devices, and provide an overview of the router and ONT.
• First-Level Support: Tangent may offer an initial support period to handle any technical issues that arise immediately after installation.

Ongoing Support and Maintenance

• Remote Support: Tangent offer 24/7 support for troubleshooting and resolving issues.
• On-Site Support: If a problem can’t be solved remotely, technicians may need to visit for maintenance or repair.
• Firmware Updates: The ONT and router may receive firmware updates to enhance security and performance.
• Signal Monitoring: Providers may monitor the connection remotely to identify potential issues proactively.

FTTH provides high-speed, low-latency internet service, making it ideal for streaming, gaming, remote work, and smart home applications.

ADSS Maintenance Service

Corrective and preventive maintenance for an All-Dielectric Self-Supporting (ADSS) network ensures that any existing issues are resolved promptly and that potential issues are addressed before they affect performance. Tangent implements both processes:

Preventive Maintenance for ADSS Network

Preventive maintenance involves proactive measures aimed at minimizing the likelihood of failures and extending the lifespan of the ADSS network.

Regular Visual Inspections

• Inspect cables, hardware, and poles for visible signs of wear, corrosion, or environmental damage.
• Check for any sagging or excessive tension that may have developed over time.

Hardware and Attachment Check

• Inspect hardware such as suspension clamps, dead-ends, and pole brackets.
• Ensure bolts and fastenings are tight and secure, as loose connections can compromise stability.

Vegetation Management

• Trim nearby trees, bushes, and vines to prevent branches or foliage from contacting or damaging the cable.
• Conduct seasonal inspections, particularly in areas with fast-growing vegetation.

Optical Testing and Signal Quality Checks

• Perform routine Optical Time-Domain Reflectometer (OTDR) tests to detect signal loss, bends, or micro-bending.
• Use power meters to monitor signal strength and identify any degradation over time.
• Conduct these tests seasonally and after extreme weather events.

Routine Cleaning and Maintenance of Splice Enclosures

• Check that splice enclosures are sealed and secure to prevent moisture ingress.
• Inspect for dirt or debris around enclosures and clean as needed to prevent signal issues.

Proactive Upgrades and Improvements

• Upgrade hardware as needed if improved versions become available, such as corrosion-resistant clamps or better brackets.
• Consider adding environmental shielding in areas prone to high UV exposure, pollution, or extreme weather.

Documentation for Preventive Maintenance

• Keep detailed records of each preventive maintenance activity, including the date, findings, and any adjustments made.
• Document environmental conditions observed, issues noted, and parts replaced or repaired.

Corrective Maintenance for ADSS Network

Corrective maintenance addresses identified problems and restores network function when performance is compromised.

Issue Identification and Assessment

• Use OTDR and power meter testing to locate any breaks, bends, or areas of signal loss.
• Analyze customer reports and network performance data to pinpoint affected segments of the ADSS network.

Site Inspection and Damage Evaluation

• Dispatch technicians to inspect the physical condition of the damaged section.
• Evaluate if the issue is due to hardware failure, environmental factors (e.g., wind damage), or interference from vegetation or animals.

Cable Repair and Replacement

• If the cable is damaged or broken, perform a repair or splice to restore continuity.
• For extensive damage, replace the affected section of the cable and ensure proper tensioning and sag.

Splicing and Connector Repair

• Conduct fusion splicing if fiber strands are damaged at splice points.
• Ensure that repaired or replaced splices are properly sealed in enclosures to protect against moisture and environmental exposure.

Hardware Replacement

• Replace worn or damaged hardware, such as broken enclosures, broken brackets, loose clamps, or rusted fasteners.
• Verify that new hardware is correctly installed and that cable tension and sag are appropriate.

Retesting and Verification

• Once repairs are completed, retest the fiber optic line using OTDR and power meters to verify signal quality and continuity.
• Perform a final inspection to confirm that the cable is secure, tensioned properly, and free of any immediate risks.

Emergency Response for Severe Issues

• In the case of severe damage (e.g., due to extreme weather or accidents), deploy an emergency response team to assess and prioritize repairs.
• Set up temporary solutions if necessary to restore service while permanent repairs are being planned.

Documentation for Corrective Maintenance

• Record all actions taken during corrective maintenance, including repair methods, materials used, and test results.
• Document the cause of the issue, such as environmental factors or hardware failure, to inform future preventive actions.
