Product Information:
The PSB/SPSB Launch Cable and Pulse Suppressor Boxes are
essential tools used with an OTDR to cover the dead zone of the
OTDR, enabling loss measurement on the first and last connections
of a fiber under test. They come in single-mode and multimode fiber
models with a wide selection of connectors for quick connection to
most OTDR and patch panel ports.
Key Features:
- Installation/troubleshooting/OTDR testing essential
- Reduces the number of matings on the OTDR connector, increasing
its lifespan - Portable SPSB and stand-alone PSB available in various
lengths - Contiguous fiber design for accurate connector loss
measurement
Choice of Configurations:
The PSB/SPSB allows for OTDR trace with launch and receive
cables, characterizing the first and last connectors of the
link.
Product Usage Instructions:
PSB Usage:
- Select the appropriate PSB model based on fiber type and
desired length. - Connect the PSB to the OTDR using the specified
connectors. - Use the PSB in conjunction with the OTDR to measure loss on
fiber connections accurately.
SPSB Usage:
- Choose the suitable SPSB model according to fiber type and
required length. - Connect the SPSB to the OTDR or patch panel ports for precise
loss measurement. - Utilize the SPSB to cover the dead zone of the OTDR for
effective testing.
FAQ:
Q: What are the available connectors for PSB/SPSB models?
A: For single-mode models -B, connectors include FC/APC, SC/APC,
FC/UPC, ST/UPC, SC/UPC, E2000/UPC, E2000/APC, LC/UPC, and LC/APC.
For multimode models -C/-D, connectors offered are FC/PC, SC/PC,
ST/PC, and LC/PC.
Q: How can I determine the appropriate PSB/SPSB model for my
testing requirements?
A: Consider the fiber type (single-mode or multimode) and the
desired length of coverage needed to select the suitable PSB or
SPSB model to ensure accurate loss measurement during OTDR
testing.

CHOICE OF CONFIGURATIONS
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 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 PSB would therefore be appropriate. EXFO offers three types of launch cables: · The stand-alone PSB comes in a rugged, compact carrying case · The portable SPSB comes in a soft, easy-to-carry-everywhere pouch
OTDR trace with launch and receive cables, characterizing the first and last connectors of the link.
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’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’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 “receive” cable. In order to obtain an accurate, complete picture of the system’s loss–which is a critical aspect of fiber commissioning–a launch test cable should always be used at both ends of the fiber link.
