Spectra-Strip now has the first truly "multi-mode" internal wide SCSI
cable available that fully meets ANSI T10/1142 D impedance requirements for both
Ultra 2 LVD (Low Voltage Differential) and Fast 20 single ended applications with
one cable. Called Spectra-Mode�, it is the latest generation of
Twist 'N' Flat�, having a characteristic impedance of 93 ohms (single ended) and
131 ohms (differential). This dual mode cable allows SCSI designers to ensure that
their Ultra 2 LVD busses operate correctly when a Fast 20 single ended device is
attached to the bus, and the system defaults to Fast 20 mode.
Unique in the industry, this is the only cable to offer programmable twist length
sections and a fully laminated construction for improved signal fidelity and greater
crosstalk control on all pairs. Compared with traditional hand lamination methods of
terminating SCSI cables, Twist 'N' Flat� affords considerable end product cost
savings.
