Satellite LNB Fiberlink - TRANSMITTER
This unique satellite L-band system utilizes a fiber optic transmitter that is attached
directly to the dish-mounted LNB. Utilize the advantages of fiber for the entire LNB-toreceiver link. With this system, there is no need for a long coaxial cable run between
the LNB and fiber optic transmitters. Use fiber optic cable for the entire connection
between the LNBs and the satellite receivers.
• Connect satellite antenna to receivers over LONG DISTANCES without loss.
• Prevent lightning damage.
• Provide HIGH SIGNAL LEVELS to feed many receivers without need for
amplification.
• Transmitter has FC/APC optical connector for connection to fiber optic receiver.
• Transmitter has one ‘F’ connector for connection to LNB signal output, and one ‘F’
connector for connection to DC power source (receiver/LNB power supply is
purchased separately).
• Receiver is a rack mounted card that mounts inside a 3RU chassis. Redundant
power supply is available for chassis.

FSS-95F5T
Application Note for #FSS-95F5T
DAWNco outdoor rated SATELLITE FIBERLINK • 1310 nm Fiber Optic Transmitter
DC Powering Safeguard Procedure
The purpose of this application note is to provide clarification to the #FSS-95F5T fiber optic transmitter powering method.
It is noted that certain precautionary powering measures should be followed to prevent damage to the power passing circuitry
in the transmitter module.
The #FSS-95F5T transmitter is powered from an external power supply through the dedicated F-type input connector
on the housing. This connector is clearly marked as “DC In”. The #FSS-95F5T transmitter also provides DC power passing
capability to power an LNB located upstream from the transmitter. The +24 VDC powering signal is present on the center
conductor of the DC Input coaxial cable as referenced to the ground shield of the cable. Internally, the 24 VDC power
signal is split and a portion is then fed to the center conductor of the F-type DC output connector. This connector is
clearly marked as “RF In/DC Power Out” on the #FSS-95F5T housing. The power-passing capability of the #FSS-95F5T is
600 mA @ +24V DC. This means that no more than 600 mA can be drawn through the DC Power Out port.
All RF and powering connections to or disconnections from the transmitter should be made only in a power-down
condition. It is necessary to turn “off” all DC power supplies to the system prior to making or breaking any RF
connections. DC power should only be applied to the transmitter once all RF connections are properly made. The center
contact of the coax cables should never come in contact with the connector outer body shells or the #FSS-95F5T housing itself.
If a DC energized RF cable comes in contact with the outer shell of the input F-connector or any other grounded surface,
it can create a short across the DC power supply, as the outer shell of the input F-connector and the #FSS-95F5T housing is
grounded. Under this condition, it is possible to pass a high DC current through the #FSS-95F5T unit and in particular, the DC
power passing circuit. This high current DC signal will cause permanent damage to the DC power passing circuits,
rendering the #FSS-95F5T unit inoperable.
Therefore, it is very important to observe the following guidelines:
!"
Do not exceed the 600 mA current limit for devices connected to the DC output of the #FSS-95F5T transmitter
!"
Ensure that all system DC power supplies are turned “off” and that no DC signal is present on the RF
cable when the RF input cable is connected to or removed from the #FSS-95F5T transmitter
!"
In all cases avoid shorting contact between the center conductor of the cable and the outer shell of the
connectors or the #FSS-95F5T housing itself
