Overview
The Fluke Networks MMC-62.5-STST is a high-quality multimode launch cable engineered for precision fiber optic network installation, inspection, and troubleshooting. By providing a controlled launch condition, this cable allows technicians to accurately measure the end-to-end insertion loss of fiber optic links using an OTDR.
Designed for reliability in demanding field environments, this cable features a 62.5/125µm core/cladding diameter to ensure compatibility with standard multimode fiber systems. With a length of 105 meters, it provides the necessary distance for effective OTDR dead-zone management and precise link characterization.
Key Features

Frequently Asked Questions
What is the primary purpose of this launch cable?
This cable is used with an OTDR to measure the total loss of a fiber link and to allow the OTDR to see the first connector in a system by overcoming the instrument's dead zone.
Is this cable compatible with 50µm fiber?
No, this model is specifically designed for 62.5/125µm multimode fiber. Using it with 50µm fiber will cause significant launch loss and inaccurate test results.
What does the ST/ST designation mean?
It indicates that the cable has ST-style connectors on both ends, which are common in many legacy multimode fiber systems.
Why is the length 105 meters?
The 105-meter length is sufficient to provide enough distance for the OTDR to stabilize and clearly identify the first connection in a network link.
Can this be used for cleaning fiber connectors?
No, this is a test cable. Proper inspection and cleaning tools should be used on the connectors before connecting them to your equipment to prevent damage.
