TCX Series Optical Transport System, Release 1

The TCX Series optical transport system is a complete open packet optical layer solution, which includes hardware, open network management, and disaggregated optical software controls. Disaggregation of the software management and optical controls from the underlying hardware provides multiple benefits including flexible deployment, scalability, enhanced automation, best-of-breed hardware support and multi-layer optimization.

The TCX Series Optical Transport System is a portfolio of products that provide the foundation of a comprehensive, open, and programmable packet-optical transport network. This release of the TCX Series Optical Transport System includes the following products:

  • TCX1000 Programmable ROADM, release x.x
  • proNX Optical Director, Release x.x.x

TCX1000 Programmable ROADM

At the center of the TCX Series Optical Transport System is the TCX1000 Programmable ROADM or TCX1000-RDM20, which works alongside amplifiers and multiplexers, such as the Juniper Networks BTI7800, to deliver the essential elements of an open line optical transport system. The TCX1000-RDM20 is a standalone, 20-port reconfigurable optical add-drop multiplexer (ROADM) that provides all features of a route and select ROADM node in a compact, disaggregated, stackable, form factor. The TCX1000-RDM20 supports a variety of network applications and topologies, including using it as a terminal node or as a single degree in a multi-degree node configuration. You can dynamically add, drop, or pass-through wavelengths. The TCX1000-RDM20 scales up to 25.6 Tbps per line. It is bit rate transparent and therefore agnostic to framing and modulation formats and uses a wavelength selective switch (WSS), which enables scalable, agile and automated networks.

Combining the TCX1000-RDM20 with integrated Coherent optics within Juniper Networks routing and switching platforms provides a very powerful and comprehensive end-to-end solution. Furthermore, you can extend the TCX Series optical line system capability to the BTI 7800 series Coherent interfaces providing flexibility to support a disaggregated model.

proNX Optical Director

The proNX Optical Director is a software controller and management system for open line systems (OLS). It is an integral component of the TCX1000 Series optical transport solution. The proNX Optical Director provides the following functionality:

  • Software control including dynamic real-time control of optical links in OLS networks. This includes automatic span loss management, automatic nodal loss management, and automatic channel power control.

    In traditional optical networks, this control function resides on the ROADMs themselves where the ROADMs exchange proprietary control messages with each other on an optical supervisory channel (OSC). This makes interworking across vendor equipment difficult and often leads to the deployment of single-sourced networks. Moving this function to a centralized software controller makes heterogeneous networks with equipment from multiple vendors possible.

  • Network management of OLS networks including network topology, network visualization, and network monitoring and troubleshooting.

    The proNX Optical Director learns and displays the topology of the network and provides various visual indicators so that you can see the health of the network at a glance and deal with problem areas in a proactive manner.

  • Device management of OLS elements including device configuration, device visualization, and device monitoring and troubleshooting.

    The proNX Optical Director discovers OLS elements and reads and displays their configuration. You can change the configuration, view the equipment inventory, pull up a visual representation of the device, or view performance monitoring counters and alarm details. Additionally, you can use the proNX Optical Director to configure supported transponders attached to the OLS element.

    Note: TCX Series elements do not support a built-in user interface such as a command line interface. You must use the proNX Optical Director to manage all TCX Series elements.

  • Service management of optical services across an OLS network including service provisioning, service activation, and service monitoring and troubleshooting.

    The proNX Optical Director supports A-to-Z provisioning and activation of optical services. You select the two service endpoints and the proNX Optical Director provides you a list of paths that you can choose for that service. When you activate the service, the proNX Optical Director automatically configures the service across all the devices in the path.

  • Web-based user interface. You can access the proNX Optical Director user interface from supported web browsers.


All products in the TCX Series Optical Transport System portfolio adhere to the Open ROADM multi-source agreement (MSA) found here . Therefore, the TCX1000-RDM20 is compatible with other ROADMs that adhere to this standard. In addition, the proNX Optical Director can also control and manage other ROADMs, multiplexers, and transponders that adhere to the Open ROADM MSA.
