25
Q

What are characteristics of S/FTP cable?

A

A

Cat 5e and Cat 6/6A. Cat 7&8 are screened/shielded types

27
Q

True or False. Cat standards apply only to wiring

A

False-connectors and interconnects are also rated to cat standards

28
Q

100BASE—T transmission pins are 1&2. What color code wre the wires terminated to these pins under T568A and B?

A

T568A- green/white and green
T568B- orange and white and orange

29
Q

Why is plenum rated cable used when cable is run in an area where building air is circulated?

A

Plenum rated cable produces minimal amounts of smoke if burned, must be self-extinguishing and must meet other strict fire safety standards.

30
Q

Which cable type consists of a single core made of solid copper surrounded by insulation, a braided metal shielding and an outer a cover?

A

Coax

31
Q

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

A

Fiber optic composition

32
Q

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).

A

Single mode fiber (SMF)

33
Q

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.

A

34
Q
