Always follow the safety guidelines when working with high power signals,
optical light can damage your eyes permanently! The best precaution is to
never look into a Light source. When inspecting connectors, always
make sure that the other end of the cable is disconnected and the light
source is switched off!
-
High quality reference cables are
crucial for accurate measurements. Make sure the reference cable(s)
matches the size of the DUT (Device Under Test) and check on cleanness.
-
To eliminate high order modes in
Multimode measurements, make a mandrel wrap (5 to 6 wraps around a rod,
the size of a pencil) in your reference cable. This will create a stable
light beam.
-
Set the OPM to the corresponding
wavelength of the transmitter or light source used and observe a stable
reading in dBm. This is an absolute power measurement and is the
reference level for attenuation (insertion loss) measurements, also
known as “relative” power measurements.
-
For Loss measurements, two or a single
reference cable(s) can be used. For a two reference cable loss
measurement method; connect the two reference cables together by means
of a bulkhead adapter and connect each other end to the transmitter
(light source) and OPM and proceed following the instructions as
outlined above.
-
After observing a stable dBm reading,
press the “REL” button on the OPM and observe a stable 0.00dB reading.
Disconnect the two reference cables and connect each end to the DUT; the
insertion loss of the DUT will be shown on the OPM LCD expressed in dB.
milliWatts to dBm
- dBm = (10Log10(milliWatts))
- 1 mW = 0 dBm
dBm to Watts
- Watts = 10((dBm
- 30)/10)
- milliWatts = 10(dBm/10)

Decibel (dB) is the unit
used to express relative differences in signal strength. It is
expressed as the base 10 logarithm of the ratio of the powers of two
signals. Signal amplitude can also be expressed in dB. Since power is
proportional to the square of a signal's amplitude (for example, a
power ratio of 100 is equivalent to an amplitude ratio of 10), dB is
expressed as follows: dB = 20 log (A1/A2)
A logarithmic measure of the ratio of two signal
levels using the formula:
dB=20Log(V1/V2)=10Log(P1/P2), or just the simplified formula,
dB=10Log(P1/P2). |
