WebMU909014C/14C6/15C/15C6. Tri-wavelength OTDR for both installation and maintenance (1310 nm/1550 nm plus filtered 1650 nm or 1625 nm) in one unit. Built-in PON Power Meter, Loss Test Set and Light Source functions. Exclusive, integrated launch fiber provides accurate initial connector measurement without external devices. Web2.1. FET-preamplifier design for the OTDR When measurement of optical fiber attenuation is of main interest in the OTDR a transimpedance FET-input preamplifier with bandwidth of 5-30MHz is preferred since it offers good sensitivity and wide dynamic range [5].

WebThe larger your dynamic range, the longer distance the OTDR can measure. To determine the OTDR’s dynamic range, the total pulse power of the laser and the sensitivity of the detector need to be factored in. Gainers and Losers. Sometimes when you test a fiber with an OTDR unit, your trace will reveal what is referred to as a gainer. The gainer ... WebDynamic range determines how far the OTDR can measure. It is measured in decibels (dB). Sometimes the distance range or display range is misleading and may refer to the maximum distance the OTDR can display, not what it can measure.
