TCX Series Optical Transport System


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 optical control management software 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 optical transport network. This release of the TCX Series Optical Transport System includes the following products:

  • TCX1000 Programmable ROADM or TCX1000-RDM20, Release 2.1 (dcian_R2.1.6_153)

  • proNX Optical Director, Release 2.0 (2.0.19)


    Requires Atomic Host Linux: 7.1711 (RedHat or CentOS)

TCX1000 Programmable ROADM

TCX1000 Programmable ROADM

At the center of the TCX Series portfolio is the TCX1000 Programmable ROADM or TCX1000-RDM20, which forms the foundation of an open, programmable, optical transport network. 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 enables you to dynamically add and drop wavelengths onto your optical network and supports a variety of network applications and topologies.

In this release, the TCX1000-RDM20 supports single span, point-to-point configurations and scales up to 19.2 Tbps per line using 200 Gbps Coherent wavelengths. It is bit rate transparent and therefore agnostic to framing and modulation formats and enables scalable, agile and automated networks.

Combining the TCX1000-RDM20 with integrated Coherent optics within Juniper Networks routing and switching platforms provides a powerful and comprehensive end-to-end solution. For a flexible, disaggregated model, the BTI7800 can be used as a disaggregated transponder layer over the TCX1000-RDM20 line system.

proNX Optical Director

proNX Optical Director

The proNX Optical Director is a distributed software platform that provides optical control and management for all TCX Series optical products. It is an integral component of the TCX1000 Series Optical Transport System.

The proNX Optical Director also provides fault, configuration, accounting, performance and security (FCAPS) functionality and optical service activation on supported transceivers in Juniper Networks equipment.

The proNX Optical Director provides the following functionality:

  • Optical control including dynamic real-time control of optical links in your optical transport networks. This includes automatic span 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 open optical line system (OLS) networks including network topology, network visualization, and network monitoring and troubleshooting.

    The proNX Optical Director 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.


    TCX Series devices 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 devices.

  • 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.

  • Endpoint management of supported transceivers on Juniper Networks equipment.

    The OLS network provides optical service connectivity between endpoint transponders (typically). These transponders can be standalone or integrated within routers and switches. Although these endpoints are not technically part of the OLS network, you can use the proNX Optical Director to configure these endpoints on supported transceivers on Juniper Networks equipment.

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