4.2.2 Connecting the RF Cables
Verify the RF input F connector type according to the ordering information, then screw on the matched RF
cable.
4.2.3 Connecting the Optical Fiber Cables
1. Verify the matched WT-1550-EM20 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 WT-1550-EM20 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.
4.2.4 Connecting the Ethernet Cable
You can connect the WT-1550-EM20 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 WT-1550-EM20.
To connect the WT-1550-EM20, 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 and to your TCP/IP network. The
Ethernet port is on the built-in transponder of the transmitter.
2. Verify that the green Link LED is illuminated, indicating that there is a connection. The Link LED is above
the Ethernet port on the rear panel.
4.2.5 Connecting Power
The WT-1550-EM20 is available in an AC power model or DC power model. After mounting the
WT-1550-EM20 in a rack, follow the power connection procedure below for the model that you are
installing.
The AC-powered WT-1550-EM20 has two optional power supplies 110V and 220V:
110V power supply has two 110 VAC (50/60 Hz) input connector that requires input voltage from 90 to 130
VAC, at 50 to 60 Hz single phase. The AC power plug is located on the rear panel.
220V power supply has two 220 VAC (50/60 Hz) input connector that requires input voltage from 150 to
265 VAC, at 50 to 60 Hz single phase. The AC power plug is located on the rear panel.
The DC-powered WT-1550-EM20 has two -48 VDC input connectors that require input voltage from -36 to
-72 VDC. The DC input connectors are located on the rear panel.
Turn on the power source. It takes about 60 seconds for all systems to operate. When connect one power
supply, the power indicator is yellow; when connect two power supplies, the power indicator is green.
