Ethernet - A new Ethernet standard that supports
100 Mbps. Fast Ethernet (10BASE-X) extend the existing Ethernet
using Category 5 twisted pair fiber optical cable.

core of one or more optical fibers that is surrounded by layers
of plastic that is use to transmits data using light. Fiber
optic cable has the ability to carry larger information at
faster speed over longer
- Connector that has double-ended terminals to facilitate
simple distribution and bussing of electrical circuits.
- Metal circular tube clamp used to create connections
The term "form,
fit and function", sometimes called F3 or FFF, in
the manufacturing and technology industries is a description
of an item's identifying characteristics. If the specifications,
or criteria, for form, fit and function of a particular item
are met, then the item may generally be considered interchangeable
with other items with the same requirements.
- Glass or plastic fiber that is used to guide light along
Optics (F.O.) - Engineering and applied science dealing
with lightwave or optical communications systems where electrical
information is converted to light energy, transmitted to another
location through optical fibers and then converted back into
- Mechanical lip on the outside of a connector that enables
it to attach to a panel or seal with a gasket.
- Cable trait that allows for bending under the influence
of outside force.
Ethylene Propylene (FEP) - FEP is similar to polytetrafluoroethylene
(PTPE) but has a melting point of about 50¢X C lower and slightly

Counts - Ehternet Frame counts are packet counts.
Each packet, as it is received, is counted. It is also labeled
as a good packet (good FCS) or a bad packet (FCS error). Occasionally,
packets are also counted by their size.
Size - Ethernet Frame size is measured from the beginning
of an Ethernet packet to the end of the packet. Frame sizes
range from 64 bytes to 1518 bytes. If VLAN tagging is added
(layer 2.5), the maximum frame size increases to 1522 bytes.
- Number of times an alternating current repeats its cycle
in one second, expressed in cycles per second, or Hertz (Hz).
Mounted - Connector attached to the outside or mating
side of a panel and can only be installed or removed from
the outside of the equipment.
- Fiber to the x (FTTx) is a collective term for
various optical fiber delivery topologies that are categorized
according to where the fiber terminates. Optical fiber is
already used for long-distance parts of the network, but metal
cabling has traditionally been used for the stretches from
the telecom facilities to the customer. FTTx deployments cover
varying amounts of that last distance. In an FTTN (fiber to
the node or fiber to the neighbourhood) deployment, the optical
fiber terminates in a cabinet which may be as much as a few
miles from the customer premises. The cabling from the street
cabinet to customer premises is usually copper. In an FTTC
(fiber to the curb or fiber to the cabinet) deployment, optical
cabling usually terminates within 300 yards of the customer
R&R - Quality control includes ongoing inspections
and data collection. However, data collection contains random
variations which have a degree of inaccuracy. Part of this
variation is due to individual differences, but another part
of this variation is due to uncertainty in the measurements
caused by variability in the measurement equipment and process.
If the measurement uncertainty is too large, the measurement
system may be unusable. A gage repeatability and reproducibility
R&R) study looks at this variability.
Gage R&R helps determine the magnitude of the variation
in a measurement system as well as the sources of this variation.
While the sources of variation can be numerous, three of these
sources are fundamental: part-to-part variation, repeatability
