1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the FKM. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting.
Note: One strand of the duplex fiber optic cable is coded using color bands at
regular intervals; you must use the color-coded strand on the associated ports at
each end of the fiber optic segment.
3. Connect the Transmit (TX) port (light colored post) on the RFL 3000 FKM to the
Receive (RX) port of the remote device. Begin with the color-coded strand of
the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post on the PM) to the Transmit (TX)
port of the remote device. Use the non-color coded fiber strand for this.
5. The LINK LED on the front of the FKM will illuminate when a proper connection
has been established at both ends (and when power is ON in the unit). If LINK is
not lit after cable connection, the normal cause is improper cable polarity. Swap the
fiber cables at the FKM connector to remedy this situation.
3.2.2 Connecting Fiber Optic SC-type and MTRJ, "Snap-In"
The following procedure applies to installations using a FKM with SC-type and
MTRJ-type fiber connectors, i.e., using FKM-MSC, FKM-MTRJ, FKM-SSC and –SSCL
single-mode.
When connecting fiber media to SC or MTRJ connectors, simply remove (and
save) the dust cover plugs and snap on the two square male connectors into the SC female
jacks of the FPM until it clicks and secures.
3.2.3 Connecting
Single-Mode Fiber Optic
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, 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 than multi-mode, and may be used to
connect nodes or switched ports, to 20+Km distance with the FKM-SSC and 40+Km
with the “long reach” FKM-SSCL.
The same procedures as for multi-mode fiber applies to single-mode fiber
connectors. Follow the steps listed in Section 3.2.2 above.
