6-10 iRM4451nn00-2 iRRH Product Description and Installation Guide
6.8 Connecting the GigE optical fronthaul cables
This section provides the procedure for connecting the GigE optical fronthaul cable to
the FH1 or FH2 SFP connector sockets. A set of detailed assembly instructions are
provided with each Rosenberger Fiber Enclosure. The instructions detail the assembly
of the enclosure over duplex fiber-optic cables..
To connect GigE optical fronthaul cables:
1. Remove the captive dust cover of the FH1 fiber optic cable entry port.
2. Remove the four (4) dust plugs on each of the duplex fiber ends and retain for
future use.
3. Insert the duplex into the SFP module recessed inside the FH1 bulkhead
connector until an audible ‘click’ is heard indicting the fiber is locked into the
module.
4. Store any slack of the fiber-optic cable inside the Rosenberger RFE plug to clear if
from getting pinched in the process of connecting the RFE plug to the bulkhead
connector.
5. Align the rails on the side of the Rosenberger RFE plug and push firmly until an
audible ‘click’ is heard indicating the RFE plug is locked into the bulkhead
connector completing the weatherproof seal..
6. If required, repeat step 1 through step 5 for the FH2 fiber optic cable entry port if
two Q-XCO fiber optic cables are used to daisy-chain or sidehaul to another
iRM4451nn00-2.
NOTE
The fronthaul Ethernet connections must be waterproofed using a self-fusing
tape made for that purpose. Refer to Required tools on page 4-1. Refer to the
recommended taping procedure in Section 6.12. The application of the tape may
vary by Installer local practice.
6.9 Connecting the RF cables
This section provides the procedure for connecting the 4.3-10 connectorized RF cables
to the iRM4451nn00-2 iRRH.
To connect the RF cables:
1. Remove the dust covers from the ANT1–ANT4 RF connectors located on the
bottom of the iRRH and retain for future use.
2. Screw the 4.3-10 RF cable coupling nut onto the ANT1 4.3-10 cable connector.
3. Secure the connection by torquing the coupling nut hand tight.
4. Repeat for connectors ANT2–ANT4.
