INSTALLATION
Optical Connectors
There are many optical connectors on the market. There are also different ways the end of the
optical connector is polished, typically “Flat” and “Angle”. The Advanced L-Band link is only
offered with SC/APC and FC/APC types of connectors (Angle Polish Connector). One of the
most common errors encountered in the field is the use of the wrong type of connectors. The
most common is using SC/PC or SC/UPC (Flat) with SC/APC (Angled). The connectors will fit
together but the optical loss will be high, performance is totally unpredictable and both con-
nectors may be permanently damaged.
Cleaning Optical Connectors
Fiber optic connectors should be clean and capped, so one can usually remove the cap and
make the connection without cleaning the connector. If there is any doubt, it is good practice
to clean the optical connectors before making the connection. Once the connection is made,
there should be no need clean the connector as long as the connector remains connected.
Use caution when handling the connectors. Any grease from your finger, scratches or small
pieces of dust or dirt can strongly affect performance. To clean a connector, use a lint-free wipe
such as Kimwipes or cotton swab, moisten with alcohol and gently wipe the tip of the connec-
tor. Let the connector air dry completely or use dry compressed air to dry.
When making the connection, be sure the key is aligned with the bulkhead connector. With SC
connectors, gently press in until the connector “clicks” in to place.
Mounting
It is suggested that the modules be mounted with the RF and Optical connectors mounted
down to prevent moisture from entering the connectors. For outdoor or high humidity envi-
ronments, always use a watertight enclosure.
Connect the optical fiber to both the transmitter and receiver. Insure the optical loss to the
receiver is less than the maximum allowed.
Verify the proper RF level out of the LNB and connect the LNB output to the RF input of the
transmitter. Adjust the transmitter and receiver gain as required.
Connect the RF out of the receiver to the distribution amplifier or TV set top receiver.
Apply power to both modules, the system should now be operational.
