TWIN dSCR / UNIVERSAL OPTICAL CONVERTER
Ref. 237201 OMS12T
Elements description
Important installation conditions:
• Before handling or connecting the equipment,
please read this manual.
• Before powering ON the equipment for the rst
time, please ensure that all cables are correctly
connected.
• When the unit is install for the rst time, please wait
about 10 seconds before check levels and quality.
The unit may take some seconds to calibrate.
• If there are any changes made to the passive
optical network, all the optical converters units
connected should be power cycled.
• Please allow air circulation around the equip-ment.
• Do not place the equipment near sources of heat or
in excessively moisture conditions.
• Do not place the equipment where it may be aected
by strong vibrations or knocks.
• Green LED:
- The LED will ash if no RF Power is detected or if
there is no optical power.
-The LED will be constantly lit if RF power is detected.
How to use the equipment safely:
• If any liquid or object falls inside the equipment,
please contact a specialized technician.
• Do not connect the equipment until all the other
connections have been made.
Precautionary measures with the
connection point:
• Take special care to avoid damaging the unprotected
ends of the connectors, as small scratches, impurities
and/or particles of dirt, oil, grease, sweat etc. may
signicantly aect the quality of the signal.
• To clean the ends of the connectors, wipe with an
appropriate cleaning wipe moistened with isopropyl
alcohol, specic for the cleaning of optical elements.
Make sure the alcohol evaporates fully before
connecting.
• Keep the connector covers and cable caps in a safe
place in case they are needed in the future.
• Always t the covers on the connectors of devices
that are not connected to cables to prevent the laser
beam from damaging the eyes.
Instructions for the optical connection:
1
Align the FC/PC connector Key-Way (Type R)
with the receptable Key-Way.
2
Push rmly to locate the key-ways, and then
rotate the coupling ring.
