6.2 Split Mounting
The IDU chassis devices are mounted in an equipment rack (see Mounting the
IDU Chassis in the Rack on page 34) and the XCVR devices at a remote
(outdoor) location.
6.2.1 Hoisting the Branching Box
The following XCVR mounting options are available:
Branching Box - The split-mount version has an outdoor branching
housing with a capacity of four XCVRs, with the options of IFC Space
Diversity and XPIC.
Two Branching Boxes - It is possible to connect two outdoor branching
boxes, enabling the use of up to eight XCVRs on a single polarization.
Two Branching Boxes with Dual Polarized Antennas – It is possible to
connect two boxes with dual polarized antennas enabling up to four
XCVRs per polarization; eight XCVRs in total.
In split-mount configuration, the indoor and outdoor parts of the system are
connected via coaxial cable. This eliminates the need for an expensive
waveguide, while still providing the convenience and interface accessibility of
an all-indoor system.
The following figure illustrates XCVR devices installed on a pole using a
branching box.
Split Mount System, 4+0
As the weight of 2 or 4 XCVRs is significant, use a hoist to mount the devices.
Note: Do not use the XCVR handles to hoist the assembled
branching box with XCVRs.
