Ribbon Optical Fiber Cable
Optical fiber cable that can be used indoors and outdoors, consists
of up to 24 strands bundled together in a single line of color - coded
ribbon. (Can be quickly spliced, uses array connectors (MPO) )
Loose tube optical fiber
Optical fiber primarily used outdoors, often has a diameter of 200 or
250um
,The most common tight-buffer diameter is...
900um
Breakout
Subunits individually jacketed strands under a single overall jacket
distribution
Multiple 900um tight-buffered strands under a single jacket
,OS2
OSP, typically loose tube construction. Used for distances up to
9842ft. (Supports wavelengths of 1310nm, 1383nm, 1550nm)
OS1
Legacy indoor, indoor - outdoor, and OSP fiber, not recommended for
new installations. (Supports wavelengths of 1310nm and 1550nm)
OM2
Is not recommended for new installations (multimode).
OM1
Is no longer recognized for new construction and should only be
used when expanding on existting system composed of OM1 fiber.
(Distance limitation of 6562ft)(Supports wavelenghths of 850nm and
1300nm)
OM4
Has the highest multimode bandwith
Multimode Optical Fiber Cable
The most common for backbone and horizontal runs within buildings
and campus environments. (50um core and 125 um cladding
, diameter.)
Mode Conditioning Patch Cords
An easy and reliable means of connecting multimode optical
fiber cabling with IEEE 802.3, 1000BASE-LX transmission equipment.
(Only recommended on OM1 and OM2 fiber channels.)
Singlemode optical fibers typically have a core size of...
9um
The standard diameter size of the cladding of industry optical fiber is...
125um
Trench/Moat
The third layer of glass that surrounds the core in both bend insensitive
singlemode fiber and bend insensitive multimode fiber to reflect lost
light back into the core.
Optical fiber cabling is required at a footage of...
328ft(100m)
