Remove the cap of the optical “INPUT” connector and connect the optical ber to the
connector.
CAUTION
Before connecting an optical ber, always clean the end face of the connector.
In addition, we recommend that the socket is also periodically cleaned (see
Section 9-2). If dirt is present on either the end face of the connector or the
socket, the insertion loss will be increased. In addition, when high optical
powers are used there is the possibility that the connectors may be damaged by
scorching. Before connecting the input light, check that the optical power does
not exceed the maximum specied level for the OTF-980. The maximum level
is +27dBm. If the optical input exceeds this limit, there is a risk of damage to the
OTF-980’s internal optical elements.
