Connecting Optical Fiber Cables
WARNING
• When the AQ7280 generates light, light is emitted from the light source ports. Do not disconnect the connected optical
fiber cables. Visual impairment may occur if the light enters the eye.
• Close the covers of any light source ports that do not have optical fiber cables connected to them. On models with two
or more light source ports, visual impairment may occur if light that is mistakenly emitted from the wrong port enters
the eye.
CAUTION
• Insert the optical fiber cable connectors slowly and straight into the optical ports. If you shake the connector to the left
and right or force it into the port, the optical connector or optical port may be damaged.
• If you use optical connectors that do not meet the specifications, the AQ7280 optical ports may be damaged. Use
optical connectors that are approved or used by national or local telecom carriers and providers in your area.
• Use optical fiber cable connectors that conform to the included universal adapter and connector adapter (the universal
adapter specified by the suffix code).
Using SC Angled Physical Contact Connectors (Suffix code -ASC of OTDR Unit)
• The SC angled physical contact connector’s ferrule tip is angle-polished. Use optical fiber cables whose connectors
are of the same type. Using a different type of connector may damage the connector end face.
• Only use SC-type (SU2005A-SCC) universal adapters on -ASC OTDR ports. Otherwise, the AQ7280 optical ports or
the optical fiber cable connectors may be damaged.
