iRM4451nn00-2 iRRH Product Description and Installation Guide 3-9
To assemble the Rosenberger RFE plug, the threaded sealing nut is first routed
onto the fiber cable, followed by installation of a split grommet and clamping claw
onto the fiber itself (see Figure 3-10 for the order of RFE assembly). The fiber
cable/split grommet/clamping claw assembly is then pressed and seated into the
plug body. Approximately 3–5 in (76–127 mm) of fiber cable, including the duplex
fiber plug, should extend beyond the outside after the RFE ‘plug’ assembly is
assembled.
The RFE plug is assembled by screwing the threaded sealing nut clockwise until it
seats into position, hand tight, on the plug body. This completes the assembly of
the RFE plug. The fiber connector is then inserted into the SFP fiber module, which
is recessed in the iRRH fronthaul port, until it ‘clicks’ into position. Any slack fiber
cable is stored inside the RFE plug. The RFE alignment rails on the RFE plug are
engaged now with the bulkhead connector. When pushed in firmly, it ‘clicks’ into
place and is locked onto the bulkhead connector completing the installation. The
RFE cannot be removed because the latch function has been disabled by the
obstruction at the latch pivot when seating the threaded sealing nut.
To remove the RFE plug from the bulkhead connector, the plug housing must be
turned counter-clockwise until obstruction of the release latches on either side of
the plug body, has been cleared. Finally, pressing on both latches at the same
time and pulling the plug body removes the RFE from the bulkhead connector.
Figure 3-10 Rosenberger RFE fiber-optic enclosure
The dust covers over the FH1 and FH2 flanges should remain in place until the
GigE optical Ethernet cables are connected and on any unused port. The dust
covers are keyed to ensure proper installation. To remove the dust cover, just pull
it off. The dust covers are re-installed in the opposite manner.
The recommended GigE fiber optic cable (x2) is OM1 62.5/125, military fiber
cable, with dual LC/dual LC termination and is provided by L-Com (FODLCMIL-nn,
or equivalent, where nn = length in meters). The Installer is responsible for
ordering this cable in the appropriate length according to site requirements.
Physical description
3-10 iRM4451nn00-2 iRRH Product Description and Installation Guide
