RTU-4000/RTU-4100 User Manual, D07-00-132P-RevA01 Page 5 of 442.0 Product IntroductionThe VeEX RTU-4000 is a rack mountable test chassis. The RTU-4100 is a test module designedto provide OTDR functionality. The RTU-4000 with installed RTU-4100 (RTU) is a rackmount testsolution that can be used for:• On-Demand testing• Continuous monitoring when paired with the OX4000 series optical switch; installed on thesame rack as the RTU.The RTU can be used in stand-alone mode or as a test probe configured as part of the VeSioncentralized server system (15.0 VeSion Overview). The RTU can be remotely accessed using theEthernet port or optional LTE model via the embedded web-based software, Fiberizer Desktop, orVeSion software application. The RTU can be used to test/monitor Point-to-Point, PON and/orDWDM networks.The RTU test capability can be increased by integrating the external OXA-4000 Optical Switch.The OXA-4000 is connected to the RTU-4000 via DB25 cable which is used to power the switchand support communication between the RTU and switch.2.1 Key Features2.1.1 RTU Fiber Probes (RTU-4100)• Dark and Active Fiber Monitoring• Catastrophic Fiber Cable failure• Preventative/Proactive Fiber Monitoring2.1.2 Optical Switches (OX4000)• Single mode fiber support• Wideband wavelength operation range• Low reflectance and ORL• 1625 nm and 1650 nm wavelength support for in-service monitoring applications
