Duplex Cable
A duplex cable is made up of two jacketed fiber cores, with their jackets fused
together to form a single cable. A duplex cable is sometimes called a zipcord
fiber jumper.
Smaller lengths of simplex and duplex interconnect cable are typically directly
connected between modules, or to a fiber panel within an enclosure.
Multi-fiber Backbone Cable
Multi-fiber backbone cable is composed of many fiber cores bundled into a
jacketed cable. These cables are often run to a fiber panel within an enclosure.
Smaller lengths of simplex or duplex interconnect cable are then typically used to
connect from the fiber panel to individual modules or networks.
What is Zipcord?
The term ‘zipcord’ refers to any cable that is a duplex cable whereby the jacket is
fused together to form a lamp cord-like cable that can be easily parted. The V-pin
connector makes sure the fiber is reversed on opposite ends of the cable so that
the Transmit end from one module is automatically connected to the Receive end
of the other module.
Multiple lengths of zipcord (catalog number 1786-FSxx) are available for use with
the 1786-RPFS module.
