ST800K Optical Power Meter

User Manual

1. Summary

ST800K Optical Power Meter, a new generation of
high-performance optical network test meter, with the
characteristics of excellent performance and fast filed ᅳ test,
has adopted the latest laser exploration and processing
technology. It is an integrated optical power meter aimed at
optical network operation, maintenance, equipment research
and development.
It can be used to test optical power within the range of
800-1700nm wave length, with the unit as nW, mW, mW, dB,
dBm. Its display resolution level and test accuracy are high.
There are 850nm, 1300nm, 1310nm, 1490nm, 1550nm,
1625nm, six kinds of wavelength calibration points. It can be
used for linearity and non-linearity test and display both direct
and relative test of optical power.
The meter is small, light and easy to carry with large LCD screen.
It can be widely used in the test of LAN, WAN, metropolitan
network, CATV net or long-distance fiber net and other
situations. It can be used 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.

You can realize turn on/off function when pressing the key. This
meter defaults auto off function is available when you turn on the
meter.
When this meter is on, short press key can open 10 minutes
Auto-off function. Press key again to close this function.
Long press button more than 2 seconds, you can turn off this
meter.

2. dBm key

Press this button to show absolute optical power measurement value.

3. 入 key: wave length choice key

You can choose one kind of six wave length, namely 850nm, 1300nm,
1310nm, 1490nm, 1550nm, 1625nm, by pressing A key and the wave
length which is chosen will be displayed on LCD screen. The default
wavelength is 1310nm; others are 1310nm, 1490nm, 1550nm,
1625nm, 850nm, 1300nm.

4. REF key

Press this key, LCD shows relative power value.

5. key: open/off backlight

Press this key to control the backlight on or off.

6. 270, 330，1K, 2KHz frequency light identification

When entering light are 270，330，1K, 2KHz modulated light, the meter
can identify frequency automatically and show it on the LCD. This
function should use with laser source.

6. Maintenance

1. Please keep the sensor surface clean, do not 니 se the dirty or

nonstandard adapter tie-in, do not insert into the port which is poorly
polished, otherwise, it will damage the sensor end.

2. Please operate carefully to replace adapter for different linkers.

The spare adapter should be stored hermetically to avoid the dust.

3. Please cover the dustproof cover to keep the interface clean

when the optical power meter is not used. Please do not put the sensor
in the air, or something of test error will be caused because of the dust.
