Before connecting the cable, remove the protective dust caps from
the tips of the fiber connectors.
Save these dust caps for future use.
Wipe clean the ends of the connectors with a soft cloth or lint-free
lens tissue dampened in alcohol.
Ensure the connectors are clean before proceeding.
One strand of the duplex fiber optic cable is coded using color bands at regular intervals.
The color-coded strand must be used on the associated ports at each end of the fiber optic
segment.
Connect the transmit (TX) port on the ML600 to the receive (RX) port
of the remote device.
Begin with the color-coded strand for this first TX-to-RX
connection.
Connect the receive (RX) port on the ML600 to the transmit (TX) port
of the remote device.
Use the non-color coded fiber strand.
The LINK LED at the fiber connector will illuminate when a proper connection has been
established and when power is ON. The normal cause of the LINK LED not illuminating after
cable connection is improper cable polarity. Swap the fiber cables at the fiber connector to
remedy this situation.
To connect fiber media to SC connectors,
Snap on the two square male connectors into the SC female jacks
of the fiber connector until it clicks and secures.
When using single-mode fiber cable, be sure to use single-mode fiber port connectors.
Single-mode fiber cable has a smaller diameter than multi-mode fiber cable (9/125
microns for single-mode versus 50/125 or 62.5/125 microns for multi-mode, where xx/xx
are the diameters of the core and the core plus the cladding respectively). Single-mode
fiber allows full bandwidth at longer distances, about 20 km with multi-mode SC.
The same procedures as for multi-mode fiber apply to single-mode fiber connectors.
Follow the steps listed in Connecting ST-type Fiber Optics (twist-lock) on page 3–3.
