Optical fiber patchcords are usually double fiber
cables that use the similar connector type as well optical fiber type for
connection purpose. However it must be kept in mind that the fiber patch cord
should definitely meet all the necessary requirements of the cable transmission
as well the physical cable specifications of TIA/EIA-568B.
It is the
TIA/EIA-568B that helps in setting the overall performance specifications for
the optical fiber patchcords being
recognized in the premises cabling standards. These days, the fiber patch
cables are normally used at cross-connects for connecting the optical fiber
links. However, they are also used as the necessary equipment for connecting
the telecommunications devices for backbone and horizontal cabling purpose.
The optical
fiber based patch cables are basically used for interconnection and
cross-connection for equipments. However, the process should be followed as
defined in the TIA/EIA-568B. Follow the placement and connection of the
Positions. The Position A should go to the Position B on every optical fiber.
Remember, the connector that needs to be plugged into the receiver should be at
the Position A and the other connector (the one that connects the transmitter)
should be at the Position B. It must be kept in mind that fiber optic patch
cord and fiber optic jumper are totally different objects. Patch cord is
basically a double fibered cable. However, it has often been noticed that the
term is used to describe single fibered cables.
According to IEEE 802.3, the term Fiber Jumper can be defined as a sort
of optical jumper cable assembly that is used for bi-directional transmission
as well information receiving purpose. Also, it should be noted that the fiber
jumper can well be a single or multi-fiber cable.
Transmitter
jumpers are those where the jumper cables gets connected to the overall light
emitting resource. Those fiber cables connected to the fiber optic power meter
are often termed as receiver jumper. Test fiber jumpers are also referred to as
reference jumpers. Fiber jumpers are always critical part of the fiber optic
test equipment setup.
