Installation Instructions

media A substance that transmits data between ports; usually fiber optic cables or
category 5 unshielded twisted pair (UTP) copper wires.
metropolitan area
network (MAN)
A broadband network that covers an area larger than a Local Area Network.
multimode fiber
(MMF)
A fiber with a core diameter larger than the wavelength of light transmitted
that you can use to propagate many modes of light. Commonly used with
LED sources for low speed and short distance lengths. Typical core sizes
(measured in microns) are 50/125, 62.5/125 and 100/140.
multiplexing
Carriage of multiple channels over a single transmission medium; a process
where a dedicated circuit is shared by multiple users. Typically, data
streams intersperse on a bit or byte basis (time division), or separate by
different carrier frequencies (frequency division).
nanometer (nm)
One billionth of a meter (10
-9
meter). A unit of measure commonly used to
express the wavelengths of light.
quad small form-
factor pluggable plus
(QSFP+)
The quad small form-factor pluggable plus (QSFP+) is a transceiver used
for data communications applications, which connects a module to a fiber
optic cable.
single-mode fiber
(SMF)
One of the various light waves transmitted in an optical fiber. Each optical
signal generates many modes, but in single-mode fiber only one mode is
transmitted. Transmission occurs through a small diameter core
(approximately 10 micrometers), with a cladding that is 10 times the core
diameter. These fibers have a potential bandwidth of 50 to 100 gigahertz
(GHz) per kilometer.
Small Form Factor
Pluggable (SFP)
A hot-swappable input and output enhancement component that allows
gigabit Ethernet ports to link with other gigabit Ethernet ports over various
media types.
Small Form Factor
Pluggable plus (SFP
+)
SFP+ transceivers are similar to SFPs in physical appearance but SFP+
transceivers provide Ethernet at 10 gigabits per second (Gbps).
unshielded twisted
pair (UTP)
A cable with one or more pairs of twisted insulated copper conductors
bound in a single plastic sheath.
