• Installation/troubleshooting/OTDR testing essential: covers the OTDRﾒs dead zone, enabling loss measurement on the fi rst and last connections of a fi ber under test
• Increase the life of the OTDR connector by reducing the number of matings on the OTDR connector
• Wide selection of connectors for quick connection to most OTDR and patch panel ports

Typically, the length of an OTDRﾒ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 dead zone used for the tests. For instance, a 1 µs pulse is approximately 100 m long; selecting
a 150 m SPSB or a 300 m LTC/PSB would therefore be appropriate.

How It Works
Link characterization is often performed using an OTDR. But even though an OTDR has the shortest dead zones, because of the way
loss is measured in a link, it does not allow the characterization of the first and last connectors without using a launch test cable,
also called a pulse suppressor box. Hereﾒs why.

The loss value associated with an event is the difference between the backscattering levels measured before and after the event.
To account for the OTDRﾒs dead zone, obtaining a backscattering level before the first connector requires inserting a certain length
of fiber between the OTDR port and the first connector of the fiber under test. At the other end of the link, the same length of fiber is
added after the last connector of the ﾓreceiveﾔ cable.

In order to obtain an accurate, complete picture of the systemﾒs lossﾗwhich is a critical aspect of fiber commissioningﾗa launch test
cable should always be used at both ends of the fiber link.
