LASER SOURCE

The wavelength o f stabilized laser source is the same as OTDR wavelength. It is used to measure the parameters of telecommunica- tion, CATV, LAN cable, insertion loss, isola- tion loss and echo loss o f optical passive devices, and wavelength responsiveness of detectors.
Open : turn on the laser source
Wave : switch the wavelength, the output wavelength is consistent with OTDR
Mode : switch the modulation frequency o f light source, CW/270/330/1000/2000Hz optional
TWINS : enter the paired output mode. This function is used with the twins function of optical power meter

warning: Looking directly at laser output may cause damage to human eyes!

OPM — OPTICAL POWER METER

The function is used to test the power of optical signal and insertion loss of various devices and optoelec- tronic components. It can identify and measure the frequency o f 270/330/1000/2000Hz optical signal.
Wave: switch the working wavelength Reference: set current power as reference power
CAL: enter t h e user calibration mode and calibrate with t h e standard light source
TWINS: identify the wavelength and frequency of the tested laser source. This function i s used with the twins function of the laser source
-50~+26dBm: received power >-10dBm
-70~+6dBm: received power >-30dBm
Absolute power, relative power and linear power are converted a s follows:
Pabs.=101gPtin./1mW
Prel.=P Abs.-PRet.

VFL —- VISUAL FAULT LOCATOR

Visible red light (650 nm) is injected into the optical fiber, and the position o f the optical fiber fault point can be judged conveniently and accurately by observing the leakage
position on the measured fiber. I t is suitable for the detection of bare optical fibers, jumpers and other high loss sections caused by near-end faults and micro-bending of
optical fibers and cables which can leak red light.
Normal : turn on redlight , continuous light
1Hz : red light flashes oncein1 second
2Hz : red light flashes twicein 1 second
Close : turn off r e d light
warning
Looking directly a t laser output may cause damage to human eyes!

OPTICAL LOSS TEST

Used to test the insertion loss of optical passive components.
The loss test steps are as follows:

1. First connect the LS and opm optical interfac- es with standard jumpers, Press [Open] and press [Reference] after the power is stable.
2. Then connect the tested part to LS and opm optical interfaces with standard jumper, Press [Open] , and “relative power” is the insertion loss of the tested part.

MAINTENANCE

Cleaning of connectors
The optical output interface of this series OTDR is a replaceable universal interface, and the end face must be kept clean during use. When the instrument fails to test the normal curve or the test result is not accurate, first consider cleaning the connector. When cleaning, be sure to turn off OTDR and visible red light fault location function. Screw off the output port and wipe the connection end face with a special dust-free paper towel or cotton swab wetted with alcohol. At the same time, please cover the dust cap after using the instrument, and keep the dust-proof clean at the same time.
Instrument screen cleaning
The display of this series of optical time domain reflectors is 4.3 inch TFT full view color LCD with capacitive touch screen. When using, do not click on the LCD with sharp objects, or the LCD screen may be damaged. When cleaning, clean the LCD screen with soft paper. Do not wipe the LCD screen with organic solvent, otherwise it may damage the LCD screen.
