Conduct fiber testing easily and accurately with wired network testers, also known as active network testers. Ideal for technicians and communications contractors, this equipment allows you to quickly certify two fibers concurrently over two wave lengths. Technicians can inspect, clean, and test fiber optic cables, and then complete their analysis with professional closeout reporting. Active network testers allow you to troubleshoot your work and measurements for upmost accuracy. The performance, functionality, and speed of active network testers vary across manufacturers and products. Some of the active network testers carried by Advanced Test Equipment Rentals can combine optical, transport, and datacom modules, and offer varying degrees of assistance for your field testing.
