5. Typical Applications

This section will discuss the use of ShinewayTech instruments. We hope this would

be beneficial to your operation.

Please read the cautions and notes carefully before carrying out actual measurement.

5.1 Connector Insertion Loss

To measure the insertion loss of a connector, a stabilized laser source and an optical
power meter (with relative measurement function) are needed. Please follow the procedure
described below:

1. Initialization: Connect the SLS series laser source to the OPM series optical power

meter using a suitable optical jumper cable with a length of 6-9 feet (2 to 3 meters) to
measure the actual optical power of stabilized laser source, as shown in Figure17.

 To ensure the accuracy of measurement, optical connectors should be kept clean.

 In the process of measurement, please always avoid looking directly into open

optic fiber, optical output, optical connectors or other laser source, for it might
cause eye injuries.

 Only under the dBm mode, reference power value can be set.

5.2 Link Loss T esting

For link loss testing, a stabilized laser source and an accurate optical power meter are
needed to measure the attenuation of a single-mode or multimode link.

Please follow the following procedures:

1. If users want to make full use of the measurement function of the instruments(laser

source and power meter), then test of the output power of laser source connected to optical
jumper cable must be performed before link testing. And connect laser source and power
meter with tested optical jumper cable, as in Figure20. Power value is noted as P1.

3. Use the formula “FORWARD L OSS (dB ) = P1 – P2”, take the dBm reading on the

power meter (P3) in step 2) and the source output power value (P1) in step 1). For example,
if P2 = -8.50dBm, and P1=-6.85dBm, then the FORWARD link loss is 1.65dB.

4. Connect laser sources and optical power meters to their respective patch panel ports

using the test jumpers, as shown in Figure22. Calculate the reverse link loss using the
formula “REVERSE LOSS (dB) = P1 – P3”.

5.Report both forward and reverse loss values.

5.3 Locate a Break within a Fiber by Visible Laser
Source

The VLS-20 injects visual red light into a fiber. The visible light escapes from the fiber
wherever the continuity is interrupted. A break always generates a highly visible output. If
the fiber is only under stress, a smaller effect may be produced. In general, however, if any
light is seen escaping from the fiber, it is an unmistakable sign that there is a problem that
must be repaired, as shown in Figure23.

The light in jacketed fiber is heavily attenuated; sometimes it necessary to darken the
room to see where the light is escaping from the fiber and locate the break.

 To ensure the accuracy of measurement, optical connectors should be kept clean.

 In the process of measurement, please always avoid looking directly into open

optic fiber, optical output, optical connectors or other laser source, for it might
cause eye injuries.

 When locating the breaks and escaping light, eyes should be kept away from optic

fiber for at least 30cm.

5.4 Locate a Failure of Connectors with Visible Laser
Source

Optic fiber wearing out often happens near or even inside connectors. It is not easy to
present convincing evidence for such failures. The following instructions may be of some
help.

If visible laser is injected into the optic fiber, however, in the far end, there is no visible

laser output. Normally, those failures occur.

The following can verify those problems.

Reverse the connection of the optic fiber, inject visible laser from the far end, and
visible laser will escape from the break.

FIGURE24. SKETCH MAP OF OPTICAL JUMPERE

If there is failure in the connector, bend optic fiber slightly till visible laser escapes

from the optic fiber, when your finger gradually move to the far end of the fiber, slowly
bend the optic fiber till there is no light escaping. If when reaches the far end, there still is
visible laser. Then, for sure, there is a break or are breaks near the connector.

 To ensure the accuracy of measurement, optical connectors should be kept clean.

 In the process of measurement, please always avoid looking directly into open

optic fiber, optical output, optical connectors or other laser source, for it might
cause eye injuries.

 When locating the breaks and escaping light, Eyes should be kept away from optic

fiber for at least 30cm.

5.5 Test Single-mode Fiber Loss with Dual-wavelength
Laser Source

The SLS-21 is a dual-wavelength laser source designed for measurement of attenuation
of single mode optic fiber. At present, most long-distance optic fiber communication are
transmitting via 1310nm and 1550nm wavelength. Therefore, we might encounter either
wavelength in testing, in this case, dual wavelength laser source becomes very important in
testing.

Now please follow the procedures below to measure attenuation of single-mode optic

fiber.

1. Connect SLS-21 with OPM-15 (or OPM-21/OPM-25) with one at leas t 3-meter lo ng
optical jumper cable. Power on both instruments and set the wavelengths of laser source and
optical power meter both to 1310nm. Reading from the optical power meter is from

-6.5dBm to -7.25dBm in our expectation per Figure25.
