OTDR & Fiber Optic Testers

An OTDR (optical time-domain reflectometer) sends light pulses into a fiber and shows where splices, connectors, bends and breaks are, and how much loss each one adds.

• Choosing a wavelength: 1310/1550nm models test dark fiber during construction and repair. Disconnect active equipment before testing; 1310/1550nm models do not test live fiber.
• MT-5510: a 5.4-inch 1310/1550nm 28/26dB OTDR with optical power meter, visual fault locator and light source that also tests 4K IP and 8MP TVI / CVI / AHD cameras, with 30W PoE and RJ45 TDR.
