SDI Vision Ecoflex LSZH ST 4.5
The SDI Vision range of 75 Ohm precision
coaxial cables comprises a Low Smoke Zero
Halogen jacketed single coax and 6 way
LSZH jacketed multicore. As with the Van
Damme HD vision range close attention has
been paid to their electrical characteristics
and tolerances to ensure trouble free
performance with SMPTE 259M SDI signals as
well as analogue video.
These cables can also be
used for shorter distance
transmission of 1.485
Gb/s HD-SDI - please
see the transmission
length guidelines.
Applications
• Transmission of SDI and analogue video signals
• Short runs of 1.485 Gb/s HD-SDI
• 6 way multicore ideal for multiple SDI runs and/or RGBHV +
composite analogue video
• Installation in public buildings, schools and colleges, government
premises and marine vessels
Application notes
• Use of precision 75 Ohm components throughout any
signal chain is imperative
• Jacket material specified as the thermoplastic polymer SHF-1;
compliant with IEC 60092 Electrical Installations in ships pt.
359 - Sheathing materials for shipboard power and
communication cables
• Fully tested and compliant with the following IEC standards
(see glossary for full description)
• IEC 60332.1 Fire resistance of a single cable
• IEC 60754.1 Amount of Halogen Gas Emissions
• IEC 60754.2 Degree of acidity of released gases
• IEC 60134.2 Measurement of smoke density
• Ultra pure oxygen free copper for outstanding sonic integrity
Transmission length guidelines
These transmission lengths have been calculated throughout to a maximum
attenuation of -30dB at the frequency corresponding to half of the actual signal data
rate for SMPTE 259 and -20dB for SMPTE 292. SMPTE and others advise that 90% of
this cable length introduces an appropriate safety factor- the chart below includes an
80% safety factor as jitter and other factors can increase dramatically in the last 20%
of a cable run.
