Installation - Pulse O3-4D1L3 U2 Manual

4. INSTALLATION

The O3-4D1L3 employs Class 1 laser products. To avoid injury, do not
look directly into the optical transceiver or into the fiber cable. Note that
the light is invisible; the optical signal cannot be detected by the eye.
1. This unit includes components that are susceptible to damage from
static electricity. DO NOT handle units without protection from
electrostatic discharge.
2. When not in use, optical connectors must be covered by dust caps to
keep airborne particles off connecting surfaces and to preserve
optimum performance.
3. Always clean fiber plugs with an approved fiber-cleaning product,
following appropriate procedures, before plugging the fiber into the
O3-4D1L3.
4. O3-4D1L3 units can be equipped with long-range transceivers which
produce a higher optical output than the receiver can tolerate. This
capability is intended for applications where long lengths of fiber will
attenuate the signal. If a long-range transceiver is used in an
application with short fibers, a 15 dB attenuator should be installed on
the transmit port to prevent bit errors and possible damage to the
receiver.
5. When connecting the O3-4D1L3 output to test equipment, verify that
the maximum input level specification of the test equipment is not
exceeded by the O3-4D1L3 output. Even intermediate-range optics
can produce levels too high for some test equipment, so attenuators
might be required. In general, when connecting the O3-4D1L3 to test
equipment, Pulsecom recommends a 5 dB attenuator when
intermediate-range optics are installed in the O3-4D1L3 and a 15 dB
attenuator when long-range optics are installed in the O3-4D1L3.
Check the specifications of the test equipment to determine if this
precaution is adequate or necessary.
The O3-4D1L3 complies with Part 15 of the Federal Communications Commission (FCC)
rules when used in the recommended mountings and installed as described in this manual.
Operation is subject to the following two conditions:
1) This device may not cause harmful interference, and
2) This device must accept any interference received, including interference that may
cause undesired operation.
