TCX Series Optical Transport System


The TCX Series Optical Transport System is a complete open packet optical layer solution that 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 for a comprehensive, open, and programmable optical transport network.

Table 1 shows the compatibility between software releases for the principal products of the TCX Series Optical Transport System:

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 for 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 device in a compact, disaggregated, stackable, form factor. The TCX1000-RDM20 enables you to dynamically add and drop wavelengths in your optical network and pass through channels from one degree to another in multi-degree ROADM nodes. The pass-through capability enables multi-directional switching in ROADM nodes up to 20 degrees.

The TCX1000-RDM20 can be deployed with Juniper Networks passive multiplexer/demultiplexers to support up to 19.2 Tbps using 96 x 200-Gbps coherent channels.

The TCX1000-RDM20 supports a diverse range of packet optical network use cases, including ultra high-capacity metro and data center interconnect applications, including point-to-point, linear multi-span, ring, and mesh network configurations. Combining the TCX1000-RDM20 with integrated coherent optics within Juniper Networks routing and switching platforms provides a powerful and comprehensive end-to-end managed solution.

TCX1000 Inline Amplifier

TCX1000 Inline Amplifier

The TCX1000 Inline Amplifier or TCX1000-ILA is a standalone erbium-doped fiber (EDFA) amplifier that supports dual optical inline amplification — two functionally separate amplifiers. The TCX1000-ILA provides periodic optical amplification of a dense wavelength-division multiplexing (DWDM) signal to enable long-distance transmission as it propagates along the fiber-optic cable. You can use the TCX1000-ILA in all TCX1000-RDM20 network configurations.



The TCX1000-2D8CMD is a passive colorless optical multiplexer/demultiplexer that provides eight colorless client ports and two line ports. You can use the TCX1000-2D8CMD to expand the number of channels supported on the TCX1000-RDM20. By connecting a line port from the TCX1000-2D8CMD to a single universal port on the TCX1000-RDM20, you can add/drop an additional eight channels to the TCX1000-RDM20. This allows you to connect more transponders to the TCX1000-RDM20 while still maintaining the spectrally programmable (colorless) operation of the TCX1000-RDM20.

The TCX1000-2D8CMD is available as an industry standard LGX cassette. Up to 3 cassettes can be housed in a TCX1000 1RU passive chassis.

The dual line ports on the TCX1000-2D8CMD enable multi-direction add/drop connectivity in multi-degree ROADM nodes or can be used for 1 + 1 redundancy. Channel switching is configured on the TCX1000-RDM20 making reconfiguration of channel paths simple and easy.

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 additionally provides fault, configuration, accounting, performance and security (FCAPS) functionality and optical service activation on Juniper Networks equipment that supports coherent DWDM interfaces.

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. Linear, ring, and mesh networks are supported.

  • 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. When you activate a protected service, the proNX Optical Director configures the protected path in addition to the primary 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.

  • Northbound RESTCONF interface for connecting to higher level management systems.

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