1 Overview

1.1 Product Overview

JW3306E fiber optic identification instrument is a new comprehensive test instrument newly

developed by our company, which not only has the function of conventional fiber optic identification

instrument to carry out nondestructive fiber optic identification detection work in any position of

single-mode and multimode fiber, but also has the optical power module and red light visual fault

location function necessary for fiber optic link construction and maintenance detection, which is a

high-performance tester in current fiber optic network maintenance detection.

5.1 Optic fiber identifier module

5.1.1 The 4-in-1 metal clamps are engraved with silkscreen markings (900/250um, 2mm/3mm),

users can choose to adjust the upper and lower mounting positions of the adapter according to

different test specifications of bare and pigtail fibers. (Figure 5-1,5-2)

Figure 5-1 Figure 5-2

5.1.2 Pull out the plastic upper cover of the fixture holding the adapter head upward (see Figure

5-3 for red arrow diagram) and remove the adapter head after the upper cover is pulled out. Re-

install it on the slide bar according to the silkscreen logo on the adapter head, and then put the plastic

top cover back on and slide it down to fix it. (Figure 5-4)

Figure 5-3 Figure 5-4

5.1.3 Put the tested fiber pigtail (bare fiber) into the metal fixture test port, and then pull the

switch of the instrument's rear housing to pull downward, so that the test fiber has a certain degree

of force, at this time the instrument screen interface displays the test data. If there is a modulation

frequency in the test link, there will be a corresponding frequency display and beeping prompt at

the bottom of the screen. (Figure 5-5, Figure 5-6).

5.2 OPM module

5.2.1 Press the meter " "power button to power on, at this time the meter displays the

test interface of the common power meter module. Slide down and pull the stopper at the

OPM/VFL logo on the right side of the meter, and there are OPM and VFL function modules on

the inside. (Figure 5-7, Figure 5-8)

Figure 5-7 Figure 5-8

5.2.2 The fiber optic signal end to be tested is inserted into the OPM power

meter port, and then in the instrument key function area to select the desired test

wavelength into, unit dBm/dB switching, etc. can be tested for the absolute power

value of the optical signal, relative power value, insertion loss, etc.

5.3 VFL module

5.3.1 Press the meter " " power button to power on, at this time the meter displays the test

interface of the common power meter module. Slide down and pull the stopper at the OPM/VFL

logo on the right side of the meter, and there are OPM and VFL function modules on the inside.

(As shown in Figure 5-7 and Figure 5-8 above).

5.3.2 Insert the fiber link end to be tested into the VFL red light source port, then press the

VFL key in the instrument key function area, at this time the upper right corner of the screen

shows the red → symbol, indicating that the VFL function is on and the optical power is output

continuously;

press the VFL key again, the red → symbol prompt flashes in the upper right corner of the

screen, and the power will be output at a frequency of 1HZ;

press the VFL key again, the upper right → symbol disappears, indicating that the VFL function

has been closed, no power output. (Figure 5-9, Figure 5-10)

6 Maintenance

1. The tester should work without obvious vibration.

2. Keep the output surface clean, use dust-free paper or cleaning cloth and anhydrous alcohol to

clean the end surface.

3. When the equipment is not in use, please protect it from dust.

4. Insert and remove the optical connector carefully.

5. Hold and place the device gently to prevent dropping and collision.

7 Warranty

We DO NOT suggest user repair the instrument by themselves.

1. The warranty period is valid for eighteen months from the date of shipment.

2. When the purchased product is found to have quality problems during this period, our company

will make appropriate repairs or replacements.

3. If the instrument in the use of the process of problems, according to the solution of common

failure tips still cannot be solved,

The user must not open the case without permission, please contact with the sales staff.

4. For the quality failure caused by production defects, the manufacturer is responsible for free

repair or replacement of the instrument, this guarantee only applies to the normal use of the
