Features for TCX1000-RDM20

20-Port Route and Select ROADM

The TCX1000-RDM20 is a reconfigurable add-drop multiplexer (ROADM) that multiplexes and demultiplexes coherent channels from the 20 universal ports to a single composite signal for transmission out the line port. You can use the universal ports as follows:

  • To directly add/drop channels in the optical network.

  • To provide a secondary multiplexing function when connected to external optical multiplexer/demultiplexer devices for channel port expansion. For example, connecting the TCX1000-2D8CMD colorless multiplexer adds an additional eight colorless and directionless ports to the TCX1000-RDM20. Connecting the Juniper Networks BTI7800-FMD96 fixed optical multiplexer-demultiplexer to a universal port enables the TCX1000-RDM20 to support 96 x 200 Gbps coherent channels.

  • To pass channels between ROADM degrees in multi-degree ROADM nodes. Pass-through allows you to create ROADM nodes that scale up to 20 degrees.

  • To support manual point-and-click service restoration by connecting to a TCX1000-2D8CMD multiplexer/demultiplexer. By connecting the universal port to a TCX1000-2D8CMD multiplexer/demultiplexer, you can create a protected service where you manually restore the service on a pre-configured protected path if a failure occurs on the primary path.

Single and Multi-Directional Switching

The switching capability within the TCX1000-RDM20 enables you to dynamically add and drop wavelengths and pass through channels from one degree to another in multi-degree ROADM nodes.

Complete End-to-End Juniper Networks Coherent Packet Optical Solution

The TCX1000-RDM20 can scale up to 19.2 Tbps on the composite line when you use 96 x 200 Gbps coherent channels on the universal ports. It supports a diverse range of packet optical network use cases, including ultra high capacity connectivity in metro and data center interconnect applications. It provides complete support for 100 Gbps and 200 Gbps coherent interfaces across Juniper Networks routing and switching platforms. The proNX Optical Director provides end-to-end optical control and management of the channel from the optical interface in the source router or switch, across the entire optical network to the optical interface in the destination router or switch.

Integrated Optical Amplification

The TCX1000-RDM20 integrates booster and pre-amplification to compensate for link and insertion losses.

Integrated OSC

This release supports a 1511 nm optical supervisory channel (OSC) for optical link negotiation.

Automatic Laser Shutdown

Due to the potential safety hazard that is posed by the high power optical outputs, the TCX1000-RDM20 has an automatic laser shutdown (ALS) mechanism that guards against the risk of direct human exposure to high-powered lasers.

The ALS mechanism acts to detect a fiber disconnection or fiber cuts along the span, and upon doing so, causes the shutdown of the high-powered WDM composite signal.

Performance Monitoring

The TCX1000-RDM20 reports performance metrics to the proNX Optical Director for all external ports on the system. The TCX1000-RDM20 also has a number of internal monitors that provide information about the total optical powers and per-channel powers (spectral information) at different points within the system. You can measure performance from these internal monitors at the following external ports:

  • Line In/Line Out ports:

    • Total power monitoring (In and Out)

    • Spectral power monitoring (In and Out)

  • OSC 0 and OSC 1 ports:

    • Total power monitoring (In and Out)

  • Universal ports:

    • Total power monitoring on Ux In (add) ports

    • Spectral power on Ux In (add) ports

Features for proNX Optical Director

This release of the proNX Optical Director adds support for the following:

  • Optical service creation in ring and mesh networks

  • Configuration of the TCX1000-2D8CMD colorless and directionless multiplexer/demultiplexer

  • Configuration of manual point-and-click service restoration

  • Nodal loss monitoring between universal ports used for pass-through

  • New fiber types for ROADM line links

  • End-to-end channel power control

  • NTP server configuration for supported MX Series and PTX Series routers and QFX Series switches

High Availability Requirements for the ProNX Optical Director

You must connect both the TCX1000-RDM20 and the proNX Optical Director to your highly available data communications network. This is required to ensure there is a redundant path to each ROADM for proNX Optical Director communications.

The proNX Optical Director software requires frequent updates on the current operating conditions of the ROADMs in your network in order to make the required intelligent decisions to maintain the optical performance of the managed device. This requirement for frequent updates drives the need for high availability and low latency in your management network.

Refer to the proNX Optical Director Installation Guide for complete details on the high availability requirements for the proNX Optical Director.
