F

Failure in Time (FIT) - Failure-In-Time (FIT) is a Unit for expressing the expected failure rate of connectors, semiconductors and other electronic devices. One FIT equals one failure and is statistically projected from the results of accelerated test procedures.

Fast 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.

Fiber Optic Cable - A cable consisting of a center glass 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

Feed-Thru - Connector that has double-ended terminals to facilitate simple distribution and bussing of electrical circuits.

Ferrule - Metal circular tube clamp used to create connections without soldering.

FFF- 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.

Fiber - Glass or plastic fiber that is used to guide light along its length.

Fiber 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 electrical information.

Flange - Mechanical lip on the outside of a connector that enables it to attach to a panel or seal with a gasket.

Flexible - Cable trait that allows for bending under the influence of outside force.

Fluorinated Ethylene Propylene (FEP) - FEP is similar to polytetrafluoroethylene (PTPE) but has a melting point of about 50¢X C lower and slightly different physical properties.

Frame 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.

Frame 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.

Frequency - Number of times an alternating current repeats its cycle in one second, expressed in cycles per second, or Hertz (Hz).

Front 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.

FTTX - 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 premises.

G

GAGA 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 (GAGA 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 and reproducibility.

Gasket - Also called a grommet; a component that forms an environmental seal by surrounding a connector interface with an elastic polymer.

Gigabit Ethernet (GbE or 1 GigE or 10 GigE) - An Ethernet protocol that increases the transmission rates of data transfer up to 1 GBps (Gigabits per second) or 1000BASE-T.
