Overview
The EXFO SPSB-B-1000-88-89 is a professional-grade soft pulse suppressor bag designed for precision optical fiber testing. It functions as an OTDR launch cable, allowing technicians to effectively characterize the first and last connectors of a fiber link by eliminating the OTDR dead zone.
Constructed for portability and field durability, this unit features a 1000-meter length of single-mode fiber housed in a protective soft pouch. It is an essential tool for installation verification and troubleshooting of fiber optic networks, ensuring accurate loss measurements and clear signal analysis.
Key Features
-
Integrated Launch Cable
Features a 1000m length of single-mode fiber to provide sufficient distance for OTDR pulse stabilization. -
Dead Zone Elimination
Allows the OTDR to accurately measure the insertion loss and reflectance of the first connector in a link. -
Durable Soft Pouch
Provides protection for the internal fiber spool during transport and field use. -
Single-Mode Compatibility
Optimized for standard single-mode fiber optic network applications. -
SC/APC to FC/UPC Connectors

Frequently Asked Questions
What is the purpose of a pulse suppressor?
A pulse suppressor (or launch cable) provides a length of fiber that allows the OTDR trace to stabilize, preventing the dead zone at the start of the fiber from obscuring the first connector.
Is this suitable for multi-mode fiber?
No, this model is specified for single-mode fiber optic applications.
What connectors are included?
This unit comes with an SC/APC connector on one end and an FC/UPC connector on the other.
Does this include a case?
Yes, it is housed in a portable soft pouch designed for field use.
Can I use this for loss measurements?
Yes, it is used to provide accurate loss measurement and link characterization of the first and last connectors in a fiber link.
