Tcx1000 Programmable Roadm Data Sheet TCX1000 PROGRAMMABLE ROADM Product Description Juniper Networks® TCX1000 Programmable ROADM is a colorless, directionless, reconfigurable optical add/drop multiplexer (ROADM) that scales up to 25.6 Tbps per line. The flexible-grid ready TCX1000 provides long-term investment protection for customers, and supports a diverse range of packet optical network use cases. Designed from the ground up as an open platform, the TCX1000 disaggregates the line system from the optical transponder layer, freeing network operators to select Product Overview and deploy transponders—whether from Juniper or a third-party solution—that best fit their network requirements and budget. An integral part of Juniper’s Unique to Juniper, TCX1000 Programmable ROADM control software is fully Programmable Photonic Layer disaggregated from the system hardware, optimizing line-system performance open line system solution, the TCX and allowing the control plane to be modified—including software upgrades and Series Optical Transport Systems updates—with far greater simplicity, flexibility, and service continuity than currently portfolio provides the foundation possible with mainstay line systems. of a comprehensive, open, and All hardware in the Juniper Networks TCX Series Optical Transport Solutions programmable packet optical portfolio is managed by Juniper Networks proNX Optical Director, which is an open, transport network.

Hardware With the TCX1000 Programmable ROADM, Juniper has established a new standard for open, programmable, and disaggregated line systems, coupling line system hardware with Juniper software to help customers lower TCO and accelerate network innovation. The TCX1000 Programmable ROADM is part of Juniper’s Programmable Photonic Layer open line system, offering a 20-port open ROADM that can reach distances of up to 3800 km without repeaters. 1 TCX1000 Programmable ROADM The TCX1000 Programmable ROADM integrates the following By enabling these connection types, the TCX1000 becomes functions into a compact 1 U chassis: a highly flexible device that supports a wide range of system applications driven by different use cases, including a simple, • Route and select wavelength selective switch (WSS) with 20 one-degree terminal with a fixed mux-demux; a one-degree node-side universal ports terminal with up to 128 channels of colorless mux-demux; and a • Integrated high-power variable gain erbium-doped fiber 20-degree switching node. amplifier (EDFA) line amplification (booster and pre-amp) Equipping the TCX1000 Programmable ROADM with 20 • Integrated spectral and total power monitoring universal node-side ports provides the flexibility to support • Integrated Ethernet optical supervisory channel (OSC) various port combinations used for channel access (single or • Field-replaceable power supplies and cooling units multiplex) and degree switching.

Page 44 www.getmyuni.com 10EC662 7.1 Introduction Satellites provide broadcast transmissions in the fullest sense of the word, since antenna footprints can be made to cover large areas of the earth. The idea of using satellites to provide direct transmissions into the home has been around for many years, and the services provided are known generally as direct broadcast satellite (DBS) services. Broadcast services include audio, television, and Internet services. 7.2 Orbital Spacing’s Orbital spacing is 9° for the high-power satellites, so adjacent satellite interference is considered nonexistent. It should be noted that although the DBS services are spaced by 9°, clusters of satellites occupy the nominal orbital positions. For example, the following satellites are located at 119°W longitude. 7.3 Power Rating Satellites primarily intended for DBS have a higher [EIRP] than for the other categories, being in the range 51 to 60 dBW. At a Regional Administrative Radio Council (RARC) meeting in 1983, the value established for DBS was 57 dBW (Mead, 2000).

  • The Near Spacecraft Rf Telecommunications System
    THE NEAR SPACECRAFT RF TELECOMMUNICATIONS SYSTEM The NEAR Spacecraft RF Telecommunications System Robert S. Bokulic, M. Katherine E. Flaherty, J. Robert Jensen, and Thomas R. McKnight A n X-band telecommunications system developed for the Near Earth Asteroid Rendezvous (NEAR) spacecraft represents an unmatched combination of performance, innovation, and cost-effectiveness for a deep space mission. It centers about two redundant X-band transponder systems that provide the command, telemetry, and tracking functions. Despite a tight development schedule, a significant amount of new technology has been used in the system. Included in the design are the most recent developments in transponder hardware, an X-band solid-state power amplifier (a deep space “first”), and efficient microstrip patch antennas. During spacecraft emergencies, a microstrip fanbeam antenna is used as part of a unique Earth acquisition algorithm. Postlaunch measurements have verified that in-flight performance closely matches predicted performance.

  • Transceivers Emergency Beacons Transponders
    Transceivers Transceiver is a word made up of "transmitter" and "receiver." There are two types of transceivers, generally either fixed or portable. The portable variety are usually less powerful but has the benefit of portability, while the more powerful fixed type are permanently in place. A GPS transceiver is often used to either confirm or back up an existing satellite signal. So, in addition to the five or more satellites that your GPS unit may be picking up on, you may also be able to find a transceiver attached to a physical location on earth. Transponders The word Transponder is a combination of "Transmitter" and "Responder," and as the name suggests a transponder is a device that reads and sends a signal. A transponder on a GPS system not only reads a position on earth from the satellites, but also transmits that signal back. Practically, a transponder could be used to track the location of an object or person, provided that person has the transponder either attached or carried on him/her. There are three types of beacons used to transmit distress signals, EPIRBs (for maritime use), ELTs Emergency Beacons [Emergency Locator Transmitter](for aviation use), and PLBs (used for land-based applications). Both transceivers and transponders can be designed to have emergency beacon capability, have a strobe light, and some are a VHF Radio. Emergency Position Indicating Radio Beacon (EPIRB) These units are for use in maritime applications. Category I EPIRBs are activated either manually or automatically. The automatic activation is triggered when the EPIRB is released from its mounted outside the cabin special bracket equipped with hydrostatic release at a water depth of 3-10 feet and is designed to “float free”.
