EXFO FTB-LTC/PSB—Launch Test Cable/Pulse Suppressor Box
Typically, the length of an OTDR's dead zone is equivalent to that of the optical pulse plus a few meters. The chosen launch test cable should therefore be longer than the pulse used for the tests. For instance, a 1 μs pulse is approximately 100 m long; selecting a 250 m LTC/PSB would therefore be appropriate.
EXFO offers two LTC/PSB types:
- The FTB-LTC module: combines with an FTB-7000 series OTDR module in the FTB-400 or FTB-200 platform
- The stand-alone PSB: comes in a rugged, compact carrying case
