In order to protect the optical connector, avoid damage on the connector, so when not in use make sure
that you place the dust cap over the connectors.
(2) Optical Connector
The standard of this optical connector is FC/PC(4-4), can connect with FC/PC
adaptor.
4-4 FC/PC connector
Notice: the tinny dust on the connector will affect the accurate of the measurement value,
so please clean the connector and the patch cord end-face before do the test.
Use the alcohol and the cotton swab to clean the connector. Dip the cotton swab with alcohol, insert
the cotton swab in the connector, slightly rotating the cotton swab, after that change a dry cotton
swab and clean it again.(4-5)
