OPTICAL TUNABLE FILTER OTF-920
7-3
CAUTION
7.2. Optical Fiber Connection
Before connecting an optical fiber, always clean the end face of the connector. In
addition, we recommend that the socket is also periodically cleaned (see Section 10.3).
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 specified level for the OTF-920. The maximum level is +20dBm. If the
optical input exceeds this limit, there is a risk of damage to the OTF-920’s internal
optical elements.
Open the cover of the optical input connector and connect the optical fiber to the connector.
Repeat the operation with the optical output connector.
