SC/UPC - ST/UPC Launch Cable, Singlemode, 1000M
Best fiber optic launch cable for precise OTDR network testing.
This OTDR optical fiber launch cable is essential for accurate loss and reflectivity measurements of fiber optic lines using an OTDR device. Designed to minimize launch pulse uncertainty, this cable functions as both a transmitting and receiving cable, effectively eliminating blind spots when testing complete link loss. It features a coiled design for easy portability and is optimized for short, medium, and long-distance network testing applications. The cable utilizes Singlemode G657A2 fiber and comes pre-terminated with LC/UPC on one end and SC/UPC on the other, housed in a ruggedized CD-style case for protection.

Know before you buy
This cable acts as a buffer between your OTDR and the fiber link you are testing. It allows the OTDR to stabilize before it reaches the first connector, which helps you identify and measure the loss of the initial connection that would otherwise be hidden in the device's 'dead zone'.
Yes, this unit is designed to function as both a transmitting and receiving cable. This allows you to measure the total insertion loss of the entire fiber link from end to end.
Yes, G657A2 is a bend-insensitive singlemode fiber that is fully compatible with standard G.652D fiber networks. It offers improved performance in tight spaces where the cable might be coiled or bent.
The ruggedized case protects the fiber from physical damage and contamination while keeping the 150-meter length neatly coiled. This makes it much easier to transport between job sites without tangling or damaging the delicate glass core.
This depends on your specific test setup. If your OTDR port is SC/UPC and your patch panel is LC/UPC, you can connect directly without adapters. If your equipment ports do not match these connectors, you will need to use a hybrid patch cord or a mating adapter.
