The Introduction of Optical Power Meter

 by www.fiber-mart.com

An Optical Power Meter typically is aware of as Fiber optical electricity meter is a gadget that used to measure the absolute optical sign and relate fiber optic loss. The time period generally refers to a gadget for trying out common energy in fiber optic systems. Fiber optical strength meter is a device for telecommunication and CATV network. Optical energy meter consists of a calibrated sensor, measuring amplifier and display. The sensor especially consists of a photodiode chosen for the gorgeous vary of wavelengths and energy levels. On the show unit, the measured optical electricity and set the wavelength are displayed. Power meters are calibrated the usage of a traceable calibration popular such as a NIST standard.

When to Use Optical Power Meter?
When you set up and terminate fiber optic cables, you want to take a look at them. A check must be performed for every fiber optic cable plant for three major areas: continuity, loss, and power. In order to do this, you’ll want a fiber optic electricity meter.

How to Use Optical Power Meter?
When you measure fiber optic electricity with a electricity meter, you have to connect the meter to the cable. Turn on the supply of power, and view the meter’s measurement. Compare the meter dimension with the unique right energy for that precise device to make positive it have acceptable energy now not too lots or too little . Correct strength dimension is so essential to fiber optic cables due to the fact the gadget works comparable to electric powered circuit voltage, and the energy have to be simply the proper quantity to work properly.

Classification of Optical Power Meter
There are two sorts of Optical Power Meter: Ordinary Optical Power Meter and PON Optical Power Meter. Ordinary optical energy meter measures the optical strength in the fiber link, generally an absolute electricity cost 850/1300/1310/1490/1550/1625nm optical wavelength. While PON Optical Power Meter is extra appropriate for measuring the fiber to the domestic (FTTH) networks. Specific measurement: PON Optical Power Meter can ship three wavelengths from a single laser output port (1310 nm, 1490 nm, 1550 nm), of which 1310nm can measure upstream transmission direction, 1490 nm and 1550 nm measure downstream direction. Upstream related with your add data, downward is down load data.

Tips for Selection and Operation

Choose the excellent probe kind and interface type.
Evaluation of calibration accuracy and manufacturing calibration procedures, and your fiber and connectors to in shape the required range.
Make positive the kind and the vary of your dimension and show decision is consistent.
With on the spot impact db insertion loss measurements.
Wear eye safety when working with high-power cables. Even with low-power layouts, it’s sensible to test the connectors with your energy meter earlier than looking.
