Unpacking and inspection
Open the shipping carton(s) and carefully inspect the
terminal and the attached cable. If there are damages,
contact CommScope product support at:
http://www.commscope.com/SupportCenter.
With each terminal a test report (VAM/Splitter Module
Assembly Performance Sheet) of the optical ports is
delivered:
Insertion Loss (IL) as well as Return Loss (RL) are tested
on 2 different wavelengths before shipment. IL is the
insertion loss between the female (non-pinned) HMFOC
on the tail and the output ports. RL is the return loss on
the output ports itself.
For an indexing terminal with a 1:8 splitter, port 1 to 8 are
the results for the forward feed adapters (ports with black
dust cap indicated respectively with number 1 to 8). Port
9 to 19 are the results for the first 11 individual fibers in
the HMFOC adapter (green dust cap, indicated with A).
Port 20 is the test result for the reverse feed adapter (red
dust cap). Image below illustrates the port numbering in
case of a 1:8 splitter.
For an indexing terminal with a 1:4 splitter, port 1 to 4 are
the results for the forward feed adapters (ports with black
dust cap indicated respectively with number 1 to 4). Port
5 to 15 are the results for the first 11 individual fibers in
the HMFOC adapter (green dust cap, indicated with A).
Port 16 is the test result for the reverse feed adapter (red
dust cap).

Installation overview
To install the indexing terminals in the network and to
build the indexing network, following main tasks must be
perfomed:
1. Mounting the terminal
(refer to section 9)
The terminal must be mounted on or within a suitable
support base or enclosure. The UMB allows the
terminal to be mounted in a variety of applications
including the following:
• Hand-Hole (below ground)
• Pole-Mount (aerial)
• Strand-Mount (aerial)
• Pedestal (at final grade)
2. Link installation (installing the HMFOC)
The terminals connect to one another via a Hardened
Multi-Fiber Optic Connector (HMFOC). The non-
pinned tail connector (HMFOC) is routed to the up-
stream component like an FDH or a previous terminal
for termination. The “green” capped MPO (pinned,
male) in the body of the terminal housing receives the
downstream tail connector (non-pinned,female).
For the indexing branch terminal, the blue adapter
port is a capped MPO (pinned) which can receive the
downstream tail from another chain.
Refer to section 8 for cable handling recommen-
dations and refer to section 10 for making the
HMFOC connection.
3. Testing the indexing chain
(refer to section 13)
After installing the indexing chain, the signal on the
drops should be tested to ensure a correct installation
of the chain.
4. Drop cable installation and connection
After the indexing chain is set up, the single drop
connection can be made. Follow local practice
for pulling and installing drop cables. Refer to the
instructions provided with the mounting system for
drop cable entry and routing. Service is enabled by
connecting the drop cable connectors to the black
dust cap adapter ports on the terminal (see section
11 and 12).
In the Indexing Only configuration, a splitter only
terminal can be installed to the single black dust cap
adapter port. The subscribers will be connected to
this splitter only terminal.
5. Reverse feed installation
If all indexing terminals are installed, a FO cable with
HMFOC connectors at both ends can be connected
to the green dust cap adapter port of the last terminal
and to a 2
nd
HMFOC connector of the FDH. Now,
all RED ports from all Indexing terminals can be
connected to subscribers. The red adapter port is a
DLX or full size hardened connector, depending on
the housing. For installation, refer to section 11 or
12).
6. Maintenance
Maintenance for the indexing terminal is limited
to cleaning the hardened adapters as needed to
maintain optimal performance. Refer to section14.
