Mechanical splice |
With respect to fiber-optic cables, a splice in which fibers
are joined mechanically (e.g., glued, crimped, or otherwise
held in place) but not fused together using heat.
Mechanical splice is the opposite of a fusion splice in
which the two fiber ends are butted and then joined by
permanently bonding the glass end-faces through the
softening of the glass, which is fused together.

Media filter |
An impedance-matching device used to change the
impedance of the cable to the expected impedance of
the connected device. For example, media filters can be
used in Token Ring networks to transform the 100 ohm
impedance of UTP cabling to the 150 ohm impedance of
media interface connections.
