After installing an optical transceiver, to test its performance is
an essential step. When all optical devices in the network are
supplied by same vendor, if the network system is working properly,
there is no need to test subcomponents separately. However, most of
the components in the network come from different vendors, so it is
very important to test the compatibility and interoperability of
optical devices, especially each optical transceiver. How to test
the compatibility of fiber optical modules?
We know that an optical transceiver consists of a transmitter and a
receiver. When the transmitter is connected to the receiver through
the optical fiber, if the BER of the whole system does not achieve
the desired effect, is the problem of transmitter or the receiver?
Or maybe there are problems with both transmitter and receiver. In
fact, the transmitter and receiver optical module will influence
each other, therefore, the standard of qualified fiber optical
transceiver is any receiver can receive the optical signal from the
transmitter which is even with the worst performance, and any
transmitter can emit optical signal which can be received by the
receiver with the worst performance.
Testing of optical transceiver is generally divided into 4 steps,
which are mainly divided into transmitter testing and receiver
testing.
Transmitter test, in testing, pay attention to the wavelength and
shape emitted by the transmitter, as well as the receiver's jitter
tolerance and bandwidth, and should note two points:
1, The quality of the input signal used to test the transmitter
must be good enough. In addition, also need to confirm the quality
of electrical measurement by jitter and eye diagram. Eye diagram is
a common method to check output waveform of the transmitter,
because the eye diagram contains abundant information and it can
reflect the overall performance of the transmitter.
2, The output optical signal of the transmitter must be measured by
eye diagram, optical modulation amplitude and extinction ratio and
so on.
Receiver test, when test the receiver, also need to pay attention
to the following two points:
3, Different with the test of transmitter, when test receiver, the
optical signal quality must be poor enough, therefore, must create
a optical pressure which can represent the worst signal, the
optical signal must be calibrated through the worst jitter and
optical power test.
4, And finally, need to test the electronic output signal of the
receiver.
In summary, testing optical transceiver is a complex task, but it
is also an indispensable step to ensure good performance.
