Common problems with copper cabinets

The Copper Cabinet Technology is a Critical Component of Access Network to ensure the range of copper services including Broadband services are provided to the customer as reliable as possible. The first step of Improving the technology is to identify the basic engineering factors that negatively impact reliability performance knowing water, copper and electricity impact services dramatically.

Factors that impact Cabinet Reliability

  • Moisture ingress,Humidity Condensation cycle
  • Extreme weather High rainfall Flooding
  • Insertion Tools, Incorrect Tool, Damaged Tool or No Tool used has a big impact on Faults
  • Degradation of Legacy modules over time
  • FTTN interventionby technicians increases fault rates
  • Poor Jumper management over time

The key features of this solution include:

1. Tool-less feature

01On both jumper and wiring side. The profiled sliders can be operated with thumb or fingers. When the slider is withdrawn the jumper stays terminated, preventing any accidental disconnection faults.

2. Gel Encapsulant

Flexible silicone gel encapsulates the terminations. This protects them from moisture ingress and condensation, and prevents subsequent faults due to corrosion. They are fully submersible for prolonged time periods making recovery from short term flooding quicker and easier. The gel stays intact for at least 100 terminations.

3. 45 degree silver-plated IDC

IDC (Insulation Displacement Connector) terminals are at 45° to the wire. This increases the surface area in contact with the wire, giving better conductivity and improving higher speed broadband performance. The conductor projects 4mm passed the terminal for a secure connection, which prevents insulation debris. The contacts are silver plated for long-term durability and for good performance with high frequency services.

4. Disconnection feature

The test ports are “disconnect”. This allows the engineer to test in both directions using the test adaptor without removing wires.

5. New design integrated strain relief

This allows the engineer to terminate cable pairs quickly and neatly during build and Fault Volume Reduction (FVR) work, with or without the wiring jig (Outrigger). Volume people can now replace connectors without need for tools or jigs.

6. High Density

The pitch between connectors gives engineers more room between modules making it easier to provide and trace jumpers. This also prevents congestion problems, which lead to faults. There is an obvious gap between every 100 pairs so the engineer can identify the circuit quickly.

7. Back mount frame

Back mounts are supplied as single columns rather than pairs riveted together and the preferred securing method is via the Primary Connection Point (PCP) mounting rails. This allows more flexibility in making best use of space, especially on Fault Volume Reduction (FVR) work or when providing Next Generation Access (NGA) ties.

8. Integrated top guides

Designed to reduce congestion and deflect jumpers away from the corners of the top two connector modules. They reduce friction and make provision and recovery of jumpers quicker and easier.

9. Replaceable Velcro straps

Used to control jumpers between columns. This prevents the bad practice of wrapping and anchoring jumpers, and allows poorly routed jumpers to be more easily corrected

10. Jacking brackets

Integral to the mounting column and are supplied with the kit. They are simply screwed and pushed into place. This keeps them away from the jumper field and away from your knuckles, and avoids the cost of buying them separately.

11. 4-pole test adaptor

This is designed to be robust and allow the engineer to test confidently in both directions without removing jumpers.

12. Outrigger

This device allows cable pairs and jumpers to be terminated without continually rotating the connector module. It speeds up the rate of installation of the connector and allows for consistent cable pair lengths.

13. Designation System

Numbers are used to designate the first circuit of each 100 pair block, and last circuit of each connector.

14. Coloured marking caps

The sliders themselves are coloured in standard green (E-side) and blue (D-side) to provide a robust identification method. Additional coloured clip-on marker caps are available with yellow being used for NGA ties and red ones can be used for highlighting other circuits.
