Data Sheet, Rev. 0 March 6, 2003 System 8000 Fiber-Optic Interfacility Links Designed to interface directly with earth station equipment, the multifaceted System 8000 interfacility link offers a wide variety of unique, site-specific interconnectivity solutions for satellite earth stations. Features n Single thread, 1:1, and 1:2 redundancy n EIRP monitoring capability n RS-232 or RS-485 serial interface n RS-232 or RS-422 data link n RFI/EMI immunity n CE approved Applications Consisting of a high-performance, highly flexible family of fiber-optic transmitter and receiver plug-ins, system 8000 allows both microwave and RF signals to be transmitted over long distances through fiberoptic cable, and thereby eliminates the need for coaxial and waveguide interconnections. A fiberoptic link between the control room and antenna site allows for convenient remote monitoring and control as well. The system can be tailored for a wide range of transmit/receive frequency bands and offers an extensive selection of unique, site-specific interconnectivity solutions for satellite earth stations, including: n n C-, extended C-, X-, and Ku-band earth stations n IF and L-band IFLs n Rain-fade site diversity n Description The system 8000 fiber-optic interfacility links represent a comprehensive and simplified approach to satellite earth station signal management and control. Essentially, the system is designed to bring microwave technology into the 21st Century by converting microwave signals into continuously variable amplitude-modulated optical signals. n n Configurable 19 in. x 3u (5.25 in.) equipment chassis that includes redundant power supplies; redundancy switching options: single thread, 1:1, and 1:2; and selectable serial interfaces, RS-232 or RS-485. Economical 70 MHz/140 MHz links for uplink antenna remoting, downconverter output distribution, and intersite connections for backup or antenna diversity. L-band links cover the 950 MHz—2050 MHz and can be used for block downconverted C-, extended C-, X-, or Ku-band signals, or for L-band Inmarsat transmit and receive applications. C-, extended C-, X-, and Ku-band uplink and downlink systems carry the main transmit and receive signals between the control room and the antenna site. Data Sheet, Rev. 0 System 8000 Fiber-Optic Interfacility Links Description (continued) Remote RF monitor links measure the composite uplink signal at the uplink EIRP monitor coupler located at the antenna’s input feed flange. n March 6, 2003 Status information, including alarms and warnings, is indicated by front panel LEDs and through standard system monitor and control serial data ports on the chassis rear panel. Monitor and control data link provides a full-duplex, fiber-optic path for either RS-232C or RS-422 data for the earth station’s monitor and control system. n Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

This permits the operator to monitor the composite transmitted RF signals conveniently, quickly, and reliably without having to go to the antenna site or invest in a spectrum analyzer for every antenna site. In applications where the system 8000 is being used for the main signal paths, these links can be included as plug-ins in the main chassis. Or, the uplink RF monitor links can be added to an existing earth station with all the output ports in one chassis in the control room. Table 19.

The standard version is for RS-422 serial data with an option for RS-232. This link provides a data path only; there is no hand shaking, so a modem must be used at each computer. Table 20.

If the fiber-optic cable containing the fiber for the primary link is broken, the fiber-optic receiver detects loss of received optical power and the output is switched to the other channel. The switching due to receiver failure works independently of the external monitoring and control (M and C) system only for the 1:1 configuration. For the 1:2 version, the external M and C must switch the input to the backup transmitter. System 8000 provides multiple redundancy options. The standard offerings are single thread, 1:1, and 1:2. The 1:1 and 1:2 configurations offer two modes of redundancy switching: automatic and manual. Automatic Mode In this mode, internal sensing and control provides automatic switching to the backup link in case of any failure in the optical system. If the laser temperature alarm or laser optical power alarm is detected at the fiber-optic transmitter, the faulty transmitter is shut off. In the 1:2 redundancy scheme, if these conditions are detected, the switch position is changed to select the backup link. The fiber-optic receiver then detects loss of received optical power and the output is switched to Manual Mode When this mode is selected, automatic switching to the backup link is turned off. This mode can be selected remotely through the M and C system or it can be selected locally by pressing the auto-off button on the front panel of the status and control plug-in on the chassis.
