O - Orange
OC-n - See Optical Carrier n
Octet - 8 bits (also called a byte).
OFSTP - Optical Fibre Standard Test Procedure.
Ohm -The electrical unit of resistance. The value of
resistance through which a potential of one volt will maintain
a current of one ampere.
Ohm's Law - Stated E=IR, I=E/R, or R=E/I, the current
"I" in a circuit is directly proportional to the voltage
"E", and inversely proportional to the resistance
"R".
Optical Carrier n - Optical signal standards. The "n"
indicates the level where the respective data rate is exactly
"n" times the first level OC-1. OC-1 has a data rate
of 51.84 Mbps. OC-3 is 3 times that rate or 155.52 Mbps, etc.
Associated with SONET.
OLTS - Optical Loss Test Set
Open - A break in the continuity of a circuit.
Optical Fibre - A thin glass or plastic filament used
for the transmission of information via light signals. The signal
carrying part of a fibre optic cable.
Optical Fibre Cable - An assembly consisting of one or
more optical fibres.
Optical Fibre Duplex Adapter - A mechanical media termination
device designed to align and join two duplex connectors.
Optical Fibre Duplex Connection - A mated assembly of
two duplex connectors and a duplex adapter.
Optical Fibre Duplex Connector - A mechanical media termination
device designed to transfer optical power between two pairs
of optical fibres.
Optical Time Domain Reflectometry - A method for evaluating
optical fibre based on detecting and measuring backscattered
(reflected) light. Used to measure fibre length and attenuation,
evaluate splice and connector joints, locate faults, and certify
cabling systems.
OSI - Open Systems Interconnection
Outside Plant - Cabling, equipment, or structures that
are out of doors.
OTDR - Optical Time Domain Reflectometry.
Outlet - A connecting device in the work area on which
a horizontal cable terminates.
Outlet Box - A metallic or non-metallic box mounted within
a wall, floor, or ceiling used to hold outlet, connector, or
transition devices.
Output - The useful signal or power delivered by a circuit or
device. |
