Camera Link cable quality and length
The m axim u m allow able Cam era Link cable length d ep end s on the qu ality of the cable u sed and the
Cam era Link strobe frequ ency. Cable qu ality d egrad es over tim e as the cable is flexed . In ad d ition, as the
Cam era Link strobe frequ ency is increased the m axim u m allow able cable length w ill d ecrease. We d o not
gu arantee good im aging p erform ance w ith low qu ality cables of
any
length. In general, w e recom m end
the u se of high qu ality cables for any cable len gth.
