Insert / Return Loss Meter By Light Source External Single Light Source Outlet

Insert/Return Loss Meter By Light Source External Single Light Source Outlet

U8503+U82021 Insert/Return loss meter and power meter is a compact, direct display instrument for the convenient measurement of return loss, insertion loss and power. With a single output port, the meter is very easy to use and ideal for fiber cable jumper manufacturers.

The U8503+U82021 is Insert/Return Loss Meter by Light Source External. The integration of a FC/APC ultra-low back reflection connector on the output port enables the use of hybrid jumpers to accommodate measurements with various connector types without compromising the return loss measurement range. When a device under test (DUT) is connected to the jumper and the DUT output is terminated, the return loss of the DUT will be displayed.

Specification

What is return loss?

When an optical fiber signal enters or leaves an optical device component (such as an optical fiber connector), discontinuity and impedance mismatch will result in reflected or echoed, reflected or returned signal power Loss, that is, Return loss, Return Loss (RL). Insertion loss is a measurement of the resulting signal value when the optical link encounters loss, while return loss is a measurement of the reflected signal loss value when the optical link encounters component access.

Calculation formula: RL=-10 lg (P0/P1), P0 indicates the reflected optical power, P1 indicates the input optical power.

The return loss value is expressed in dB and is usually negative, so the larger the return loss value, the better, with typical specifications ranging from -15 to -60 dB. According to industry standards, the return loss of Ultra PC polished fiber optic connectors should be greater than 50dB, and the return loss of oblique polished is usually greater than 60dB. The PC type must be greater than 40dB. For multimode fibers, the typical RL value is between 20 and 40 dB.
