Description
The system 8000 fiber-optic interfacility links repre- sent a comprehensive and simplified approach to satellite earth station signal management and con- trol. Essentially, the system is designed to bring microwave technology into the 21 st Century by con- verting microwave signals into continuously variable amplitude-modulated optical signals. Consisting of a high-performance, highly flexible fam- ily of fiber-optic transmitter and receiver plug-ins, system 8000 allows both microwave and RF signals to be transmitted over long distances through fiber- optic cable, and thereby eliminates the need for coaxial and waveguide interconnections. A fiber- optic 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 trans- mit/receive frequency bands and offers an extensive selection of unique, site-specific interconnectivity solutions for satellite earth stations, including: n Configurable 19 in. x 3u (5.25 in.) equipment chas- sis that includes redundant power supplies; redun- dancy switching options: single thread, 1:1, and 1:2; and selectable serial interfaces, RS-232 or RS-485. n Economical 70 MHz/140 MHz links for uplink antenna remoting, downconverter output distribu- tion, and intersite connections for backup or antenna diversity. n 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. n 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. 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.
Data Sheet, Rev. 0 System 8000 Fiber-Optic Interfacility Links March 6, 2003 ORTEL a Division of EMCORE Description (continued) n Remote RF monitor links measure the composite uplink signal at the uplink EIRP monitor coupler located at the antenna’s input feed flange. n 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. 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. Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso- lute 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. *A 500 V transient developed across 100 pF is discharged through 1500 Ω to each connector pin without damaging the system. Typical Block Diagram As indicated in the block diagram below, the input and output amplifiers are integral to the system 8000. The tables presented throughout the following sections, however, give the expected performance of each functional block in the link with respect to their corresponding performance bands, including 70 MHz—140 MHz, L-band, and C-, X-, and Ku-band interfacility links. These specifications, along with those for remote RF signal monitor interfacility links and fiber-optic data links, are presented to aid in generating level diagrams for overall system analysis.
