How to test a fiber optic transceiver
When optical transceiver was first expanded,
establishing the performance of it was outspoken. 
Today, most optical networks use components that
may come from different suppliers.

Fiber optic transceiver
You need to check the specifications and it needs
to be assured that any receiver will interoperate
with a worst-case transmitter.
If a receiver needs a minimum level of power to
manage the system BER target, then that level
will precept the minimum allowed output power of
the transmitter.
If the receiver can permit a reliable level of
jitter, this will be used to define the highest
acceptable jitter from the transmitter.

Four basic steps in inspecting an optical
transceiver
Transmitter testing
Transmitter parameters may include wavelength and
shape of the output waveform. The receiver may
specify tolerance to jitter and bandwidth.
5
Two steps to examine a transmitter
The input signal used to test the transmitter
must be good enough.
Measurements of jitter and an eye mask test must
be performed to confirm the quality using
electrical measurements.
An eye mask test is a common method to view the
transmitter waveform and present a  vast quantity
of information about overall transmitter
performance.

Receiver Testing
One must ensure that the input signal is of good
enough quality, testing the receiver associated
with sending a signal that is of poor enough
quality. 
This is an optical signal, which needs to be
calibrated using jitter and optical power
measurements.

Testing the electrical output of the receiver
must be achieved. Three basic categories of tests
must be performed.
Jitter tracking and tolerance, which examine the
efficacy of the internal clock recovery circuit
to track jitter within its loop bandwidth.
The mask test is usually conducted by a BER (bit
error ratio) depth. Jitter budget test, which
tests a number of certain types of jitter.

Benefits of Optical Fiber
For short distance application, such as a network
in an office building, fiberoptic cabling can
save space in cable ducts.
This is because a single fiber can carry much
more data than electrical cables such as standard
category 5 Ethernet cabling, which typically runs
at 100 Mbit/s or 1 Gbit/s speeds.
Fiber is also immune to electrical interference
there is no cross-talk between signals in
different cables, and no pickup of environmental
noise.
They can also be used in environments where
explosive fumes are present, without danger of
ignition.
