The TREND Networks R240-PMIV FiberMASTER Multimode/Single-Mode Power Meter offers size, simplicity, and value without any compromises. Due to the small size, the instrument is easy to carry and operate while the ruggedized housing aids in protecting the instrument. The simplified setup options makes the instrument easy to use, saving users time spent on training and reducing the likelihood of errors. This instrument enables cable installers to get the dependable test results needed, while saving users thousands of dollars.

The R240-PMIV is configured to include interchangeable LC, SC, FC, and ST connectors, a video probe port, and VFL.

The R240-PMIV can be used to measure attenuation in multimode or single-mode cabling. The instrument supports the R240-VIP FiberMASTER Video Inspection Probe (not included) to capture images of the connector on each end of the cabling. When paired with the user's OTDR and light source, the OTDR can be used to directly measure cable attenuation or to measure the output power of optical equipment for troubleshooting. The instrument's high dynamic range allows for troubleshooting of LAN and Telecom networks.

The Visual Fault Locator (VFL) emits visible red light at the 650 nm wavelength. The intended function is to allow an operator to identify the exact location of a break, micro bend, or other discontinuity in a fiber optic cable. As the radiation is visible, light emanating from a break or micro bend enables the user to locate the exact position of a fault even at very short distances that would not be detectable by conventional means such as an OTDR. This is also useful for identifying a particular fiber in a cable by exciting the fiber to be located with visible radiation.
