Cable for use in building voids designed to be fire resistant and to produce a minimal amount of smoke if burned.
Plenium
a_________ space is a void in a building designed to carry heating, ventilation, and air conditioning (HVAC) systems
Plenium
General purpose (nonplenum) cabling uses _________________________ jackets and insulation
PVC (polyvinyl chloride)
Data cable that is plenum-rated under the US National Electrical Code (NEC) is marked _______________________
CMP/MMP
Data cable that is riser-rated under the NEC is marked __________________
CMR/MPR
Media type using two separate conductors that share a common axis categorized using the Radio Grade (RG) specifications.
Coaxial Cable
Screw down connector used with coaxial cable.
F- Type Connectors
Media type similar to coax but with two inner conductors to improve performance.
Twinaxial
Twinax is used for datacenter 10 GbE (unofficially referred to as 10GBASE-CR) and _______________________ interconnects of up to about 5 meters for passive cable types and 10 meters for active cable types
40 GbE (40GBASE-CR4)
A single optical fiber is constructed from three elements
Core
Cladding
Buffer or protective plastic coating
Fiber optic cable type that uses laser diodes and narrow core construction to support high bandwidths over distances of over 5 km.
Single Mode Fiber (SMF)
Fiber optic cable type using LED or vertical cavity surface emitting laser optics and graded using optical multimode types for core size and bandwidth.
Multi-Mode Fiber (MMF)
has a small core (8 to 10 microns) and a long wavelength, near infrared (1310 nm or 1550 nm) light signal, generated by a laser
