Fiber Optics Diagnostics (TRACETEK)
Q5: If I lose my TRACETEK launch cable, do I need to replace it with a special
one?
A5: No, the included launch cable with TRACETEK is an ordinary FC-ST multimode or
FC-FC single mode jumper. Any high-quality replacement jumper will work, and there
is no calibration necessary. The length of the launch cable is only important in that its
length is added to your distance measurements and keeping a conveniently short
cable will minimize any offset in length measurements. TRACETEK utilizes a special
technology that allows the use of very short launch cables, unlike an OTDR whose
front-end dead zone may be 20-100 m long and require the use of very long launch
cables.
