What is measurement standard for wire thickness
American Wire Gauge(AWG)
What are characteristics of S/FTP cable?
Twisted pair type of copper cable using a braided outer screen and foil shielding for each pair to reduce interference
Which categories of U/UTP cable are certified to carry data transmission faster than 100 Mbps?
Cat 5e and Cat 6/6A. Cat 7&8 are screened/shielded types
True or False. Cat standards apply only to wiring
False-connectors and interconnects are also rated to cat standards
100BASE—T transmission pins are 1&2. What color code wre the wires terminated to these pins under T568A and B?
T568A- green/white and green
T568B- orange and white and orange
Why is plenum rated cable used when cable is run in an area where building air is circulated?
Plenum rated cable produces minimal amounts of smoke if burned, must be self-extinguishing and must meet other strict fire safety standards.
Which cable type consists of a single core made of solid copper surrounded by insulation, a braided metal shielding and an outer a cover?
Coax
Core-provides transmission path for light signals
Cladding reflects signals back into the waveguide as efficiently as possible so that light signal travels along waveguide by multiple internal reflection.
Buffer-protective plastic coating
Fiber optic composition
Fiber optic cable type that uses laser diodes and narrow core (8-10 microns) construction to support high bandwidths over distances of over 5km. Long wavelength near infared( 1310 or 1550 nm). Supports data rates up to 100 Gbps. OS1 (indoor) and OS2 (outdoor).
Single mode fiber (SMF)
Fiber optic cable type using LED or vertical cavity surface emitting master optics and graded using optical multi mode types for core size and bandwidth. Larger core (62.5 or 50 microns) and shorter wavelength (850-1300 nm) transmitted in multiple waves of varying length. Less expensive optics but does not support such high signaling speeds or long distances and is more suitable for LANs than WANs.
Multi mode Fiber (MMF)
Classification system for multimode fiber designating core size and modal bandwidth. OM1/OM2 (62.5 and 50 microns respectively)
