Cable Terminations
RJ45 Cable Termination Standards
- The standard discussed is T568B.
- Importance of knowing the wiring color order for proper termination.
Pass-Through RJ45 Connectors
- Description of Pass-Through:
- RJ45 connectors with additional holes to pass wires through, ensuring correct wire placement.
- After feeding the wires through, excess cable can be snipped off easily, alleviating the guesswork involved in cutting wires to length.
- Advantage:
- Easier to terminate cables as it reduces the risk of incorrect lengths when trimming wires.
- Cost-effectiveness: Not significantly more expensive than standard connectors.
Patch Panels and Keystone Connectors
- Patch Panels
- Located at the back of network setups, they help organize and connect various network cables.
- Similar functionality to keystone connectors.
- Installation Process:
- Expose wire to proper length before inserting it into the terminal.
- Use punch down tool to secure the exposed wire into the panel.
- Key Considerations:
- Adequate cable slack is necessary to ensure ease of work without excess cable.
- After installation, cover plates need to be placed back on the wall.
Project Overview: Network Overhaul
Next Week's Project Description
- Students will handle a network overhaul assignment:
- Involves running cables and placing network devices in an office following a specific client's requirements.
- Project Preparation:
- Proposals must be comprehensive, considering details such as:
- The number of cables needed in relation to the office layout.
- Exact distances for cable runs.
- Cable types to be used and their respective lengths.
Distance Calculation
- Students must consider complete distances for cable runs, including:
- Vertical distances (e.g., how far a cable runs up a wall).
- Horizontal distances (e.g., between rooms).
- Example of Calculating Distance:
- If a wall is 10 feet high and the patch panel is installed at 5 feet:
- 5 feet up + 30 feet across + 1 foot down would be 36 feet total, with 6 inches accounted for slack on each side (total of 37 feet).
Cables and Tools Used in Installations
- Installation Techniques
- Students will learn about tools such as fish sticks for running cables through contained spaces (walls, ceilings).
- Purpose: To guide wires to the desired location efficiently, especially in existing infrastructure with drywall.
- Mounting and Connecting Equipment
- Ensuring that each device, such as switches, are appropriately placed next to patch panels for optimal network performance.
- All network equipment connections (like routers and switches) must be made correctly to maintain network functionality.
Exam Details and Schedule
- Assessment Structure
- There will be a 50-question exam similar to previous ITSD exams.
- Project activities scheduled for the morning, while the exam will occur later on the same day.
- Field Trip Information
- Students will participate in an external visit to TGS post-project, emphasizing hands-on learning related to the course.
Fiber Optic Cables
Types of Fiber Optic Cables
Single Mode Fiber:
Designed for long-distance communication.
Transmits single light beams at higher transmission rates.
Multimode Fiber:
Used for shorter distances (typically within Local Area Networks).
Transmits multiple light beams allowing for multiple simultaneous data streams.
Performance Comparison:
- Both fiber types offer significantly higher throughput speeds compared to traditional coaxial or Ethernet cabling.
Questions and Wrap-Up
- Open forum for questions from students regarding the topics discussed.
- Reminder to ensure preparedness for upcoming assignments and concepts.
