Chapter 4 Installation
4.5 Cabinet Installation
4.5.1 Installation Mode Instruction
According to different installation environments, there are three modes of R8860E GU198
installation:
Pole-mount installation
Wall-mount installation
Gantry-mount installation
Simplified-cabinet integrative Installation
4.5.2 Installation Methods and Accessories
There are two installation methods for R8860E GU198, as below:
Pole mounted installation (Pole Mounting Kit): It is suggested that the diameter of
installation pole should be 60 mm ~ 120 mm.
Pole mounted installation (Universal Sheet-Metal Kit): It is suggested that the
diameter of installation pole should be 60 mm ~ 114 mm.
Wall mounted installation.
Note:
The universal sheet-metal kit also support channel iron and angle iron. The supported
channel width is 50mm–100mm. The supported angle iron width is 63mm-80mm. (The
installation method is similar to the pole installation.)
4.5.2.1 Installation Accessories
The installation accessories of R8860E GU198 and their functions are shown in Table 4-3.

4.6.9 Installing Frequency Point Extension Cable
Prerequisites
The two R8860E GU198 cabinets to be combined must be installed and fixed successfully.
Context
After the combination of cabinets, the R8860E GU198 can support 8 carrier sectors at
most.
The two R8860E GU198 cabinets are connected through their connecting interfaces such
as RXin and RXout by two frequency point extension cables. Figure 4-48 shows the
structure of the frequency point cable. End A and End B are N connectors (male).
The 2M 1/2″ jumper is often used for the frequency point extension cable. It may be
prepared on site if necessary.
Figure 4-48 Frequency Point Extension Cable
Steps
1. Connect End A of the frequency point extension cable to the frequency point extension
interface RXIN of one R8860E GU198;
2. Connect End B to RXout of the other R8860E GU198;
3. Connect the remaining RXin/RXout interfaces of the two combined cabinets with the
other frequency point extension cable.

4.7.2 Checking Cable Installation
4.7.2.1 Cables Installation General Specification
Optical Fiber
Note:
The length of optical fiber is decided by engineering survey (1 Tx, 1 Rx).
The technical specifications of optical fiber are as follows:
The optical fiber is a single mode with End B adopting two DLC/PC connectors.
The insertion loss is less that 0.3 dB.
The return loss is less than 45 dB.
If optical fiber is to be used outdoor, then
1. Take waterproof and anti- ultraviolet protection measures.
2. Make sure that working temperature is in between -40 to 80oC.
The sheath of optical fiber is black in color with a diameter of 7 mm. Under the sheath,
there are two cores optical wires (yellow and blue color) with substantial amount of
protection padding.
The maximum distance between core optical wires (including both DLC/PC
connectors) and sheathed optical fiber is 350 mm.
ZTE supplies 15 m, 25 m, 35 m. 50 m, 70 m, 100 m, and 130 m long fiber cables.
The 20 mm long black Pyrocondensation cannula should be added in between optical
core wires and sheathed optical fiber.
The label attached at both ends should satisfy the requirements of ZTE Cable
Designing Criteria – Label Designing and Usage Requirements.
AISG Cable
The following are the technical specification of AISG cable:
Table 4-8 illustrates the connection relationship of both ends. Make sure to enclose
End A connection by black cannula completely after connecting.

ZXSDR R8860E GU198 User Manual
Steps
1. The power and grounding cables are laid separately from other cables. If the power
and grounding cables are to be laid parallel with other cables, then at least a distance
of 20 cm is maintained between them.
2. The cable labels are intact on both sides of power and grounding cables. The labels
are attached at almost 2 cm from cable copper lug.
3. Entire power and grounding cables are made from one material with no connections
in between.
4. A single grounding point on the grounding busbar just connects to a piece of
equipment.
5. Copper lugs on both ends of power and grounding cables are soldered or pressed
firmly.
6. The shortest route between the grounding cables and grounding busbar is adopted.
7. Power and grounding cables at connecting terminals and lug handles are properly
insulated using either insulated tapes or heat shrink tubes.
8. The redundant length of power and grounding cables is cut to avoid wrapping each
other.
– End of Steps –
4.7.2.3 Optical Fiber Installation Check
Context
The fiber cable installation should meet the following specifications:
Steps
1. Do not fold optical fiber at 90o. For optical fiber that is to be laid outdoors, minimal
twist radius should be atleast greater than 90 mm. Whereas for optical fiber that is to
be laid indoors, minimal twist radius should be atleast greater than 30 mm.
2. After installation, any surplus optical fiber should be put back in the fiber card for
convenience.
3. During installation, minimize optical fiber twist and turn, as much as possible.
4. The binding force should be proper to ensure that binding gaps are less 0.5 m.
5. Make sure that labels at both ends of optical fiber are intact and clear.
