 Brief Introduction

TM503N Optical Power MultiMeter, a new generation of high-performance optical network test meter, with the characteristics of excellent performance and fast filed–test, has adopted the latest laser exploration and processing technology. It is a compositive optical power meter aimed at optical network maintenance, equipment research and development.

It can be used to test optical power within the range of 800~1600nm wave length, with the unit asμW,dB and dBm. Its display resolution level and test accuracy are high. There are 850nm, 980nm, 1300nm, 1310nm, 1550nm, 1490nm six kinds of wavelength calibration points. It can be used for linearity and non- linearity test and it can display both direct and relative test of optical power. Meanwhile it also has storage, page up/down functions for the test figure. The instrument is small, light and easy to carry with large LCD screen. It can be widely used in the test of LAN, wide-area network, metropolitan network, CATV net or long-distance fiber net and other situations. It can be used to distinguish the fiber, to test fiber loss accurately, to check the fiber continuity and to help to evaluate the transmission quality of fiber chain with the laser source.
