E. Make OC3 Connections
O3-4D1L3 modules have LC optical connectors. Follow the steps in Procedure 3 to make
OC3 connections.
DANGER
Units employ Class 1 laser products. To avoid injury, do not look directly
into the optical transceiver or into the fiber cable. Note that the light is
invisible; the optical signal cannot be detected by the eye.
Procedure 3. Making OC3 Connections
STEP
ACTION
1
Before plugging in the OC3 fiber, verify that the O3-4D1L3 front-panel OC3
indicator is red. If the shelf is properly powered and the OC3 indicator is off
or green when no fiber cables are connected, the unit is defective and should
be replaced.
2
Remove the protective dust cover from the front-panel OC3 LC jack labeled
RX/TX.
3
Plug in the OC3 fiber cable.
4
If the far-end OC3 connection has already been made, the OC3 indicator
should turn green or, if there is a far-end trouble, turn solid yellow.
If the OC3 indicator remains red:
•
Verify that the correct laser transceiver is properly latched into the OC3
socket.
•
Verify that fiber cables are in good condition and that fiber connectors are
clean. If required, clean the connectors with special lint-free pads in
accordance with standard procedures.
•
Verify that the optical path loss does not exceed the capabilities of the
far-end laser. If so, replace the far-end unit with one designed to support
longer OC3 fiber links.
•
If the OC3 indicator remains red, the O3-4D1L3 module is defective and
should be replaced.
