Using the Simplified Cards:
These cards are designed for rapid recall. Focus on the acronyms and key words. Remember to link the definitions to the practical applications you learn about in your Network+ studies.
Duplex Fiber
Definition: 2 fiber strands: 1 transmit (Tx), 1 receive (Rx). Essential for two-way comms.
Fiber Polarity (A to B)
Tx port connects to Rx port (crossover). Odd # of crossover elements. Prevents signal loss.
UPC (Ultra Physical Contact)
Fiber connector finish; polished, slightly curved. Don’t mix w/ APC! SMF typically Blue.
APC (Angled Physical Contact)
Fiber connector finish; angled polish. Don’t mix w/ UPC! Often not Ethernet port compatible. SMF typically Green.
OM1 Fiber
Multimode Fiber. Orange jacket, beige connector.
OM2 Fiber
Multimode Fiber. Orange jacket, black connector.
SMF (Single-Mode Fiber)
Long-distance, high bandwidth fiber. Yellow jacket. Blue connector (UPC), Green connector (APC).
OM3/OM4 Fiber
Multimode Fiber, laser-optimized. Aqua jacket & connector
Fiber Repeaters/Amplifiers
Strengthen fiber signals over long distances, counteracting degradation.
