4.3.2 Connecting the RF Cables
Verify the RF input F connector type according to the ordering information, then
screw on the matched RF cable.
4.3.3 Connecting the Optical Fiber Cables
OTM-1550L
has one or two optical connectors.
DANGER:
The fiber carries invisible laser radiation.
AVOID
DIRECT EXPOSURE TO BEAM
. Never operate the unit with a
broken fiber or with a fiber connector disconnected.
1. Verify the matched
OTM-1550L
fiber cable connector type according to the
ordering information.
2. Verify that the fiber cable connector has been cleaned properly. If the fiber cable
connector needs to be cleaned, follow the cleaning procedure outlined in “Cleaning
Patch Cord or Pigtail Fiber Optical Connectors”.
3. Verify that the
OTM-1550L
optical connector has not been exposed to any
contamination.
NOTE:
Any contamination of optical connector can significantly
degrade optical link performance. This degradation will most likely
manifest itself as poor signal-to-noise (SNR) performance.
4. Note to butt the nick of the connectors and align them accordingly.
4.3.4 Connecting the Ethernet Cable
You can connect the
OTM-1550L
to your TCP/IP network in order to monitor and
control the transmitter remotely. After you complete the installation procedures
described in this chapter, you can use a network management system (NMS) to
monitor and control the
OTM-1550L
.
To connect the
OTM-1550L
, you must use a shielded and grounded Category 5
Ethernet cable.
To connect the Ethernet cable:
1. Connect an Ethernet cable to the transmitter’s RJ-45 Ethernet port. The Ethernet
port is on the rear panel of the transmitter.
2. Verify that the green Link LED is illuminated, indicating that there is a connection.
