It is a metal structure used to form L,T,X or Y shaped intersections quickly without cutting or bending trays.
This equipment is used to give curves to cables at the intersection.
Network Patch Cable
It is an electrical or optical cable that is used to connect two electrical/electronic devices can be connected using patch cables.
It is a category of cable that forms a part of structured cabling for networks. It can carry many other signals such as basic voice services and token ring. It is an enhanced version of Cat5 that adds specification for far end crosstalk.
Attenuation Crosstalk Ratio (ACR)
The difference between attenuation and crosstalk measured in dB, at a given frequency. A quality factor for cabling to assure that signal sent down a twisted pair is stronger at the receiving end of the cable than any interference imposed on the same pair by crosstalk from other pairs. DAS Dual Attachment Station. Term used with FDDI networks to denote a station that attaches to both the primary and secondary rings.
Graded Index Fiber
A multimode fiber optic cable design in which the index of refraction of the core is lower toward the outside of the core and progressively increases towards the center of the core, thereby reducing modal dispersion of the signal.
The slight movement of a transmission signal in time or phase that can introduce errors and loss of synchronization. More jitter will be encountered with longer cables, cables with higher attenuation, and signals at higher data rates. Also, called phase jitter, timing distortion, or intersymbol interference.
