3.1 Optical Cabling Flashcards
What is the primary medium used in fiber optic cables?
Light, making them immune to electromagnetic interference (EMI).
What are the two main types of fiber optic cables?
Single Mode Fiber (SMF) and Multimode Fiber (MMF).
What is the core size of single mode fiber?
8.3–10 microns.
What is the core size of multimode fiber?
50–100 microns.
What are the typical use cases for single mode fiber?
Long-distance communication, such as intercity or transoceanic connections.
What are the typical use cases for multimode fiber?
Short-distance communication, such as data centers and office networks.
What is the color of single mode fiber sheathing?
Yellow.
What is the color of multimode fiber sheathing?
Aqua blue or orange.
What are the four common fiber optic connectors?
SC (Subscriber Connector), ST (Straight Tip), LC (Lucent Connector), and MTRJ (Mechanical Transfer Registered Jack).
What is unique about the SC connector?
Known as ‘stick and click,’ it has separate cables for transmit and receive.
What is unique about the ST connector?
Known as ‘stick and twist,’ it uses a twist mechanism for securing the connection.
What is unique about the LC connector?
Known as the ‘love connector,’ it is compact with side-by-side cables, ideal for high-density environments.
What is unique about the MTRJ connector?
Combines transmit and receive in a single plastic housing, saving space.
What is the maximum typical distance for multimode fiber?
Approximately 2 kilometers.
Why is fiber optic cable installation more complex than copper cable installation?
It requires specialized tools and training.
