Features

This section describes the features for the TCX Series Optical Transport System, Release 1.0, which enables the following features:

Features for TCX1000-RDM20

20-Port Route and Select ROADM

The TCX1000-RDM20 is a reconfigurable add-drop multiplexer (ROADM) that multiplexes and demulitiplexes Coherent channels from the 20 universal ports to a single composite signal for transmission out the line port. You can use the universal ports to dynamically add and drop channels onto your optical network or, to multiply the number of channels the ROADM supports, you can connect the BTI7800-FMD96 fixed optical multiplexer-demultiplexer to a single universal port. This configurations supports up to 96 channels with 50GHz channel spacing. The universal ports support channel wavelengths from 1528.578 nm through 1566.928 nm and frequency ranges 191.325 THz through 196.125 THz respectively.

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 200 Gbps Coherent wavelengths on the universal add/drop ports. It supports a diverse range of packet-optical network use cases, including ultra high capacity connectivity in the metro and between data centers. It provides complete support for 100 Gbps and 200 GbpsCoherent interfaces across Juniper Networks and BTI platforms.

Integrated Optical Amplification

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

Integrated OSC

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

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 Input (add) ports
    • Spectral power on Ux Input (add) ports

Features for proNX Optical Director

This is the first release of the proNX Optical Director.

The proNX Optical Director receives streams of real-time optical link measurements from all the TCX1000 Series elements under management. From this data, the proNX Optical Director builds an always current view of the optical links in the network. This allows the proNX Optical Director to make real-time control decisions on all aspects of optical link management, including the following:

  • Channel power control and equalization
  • Span loss management
  • Graceful ramp up and ramp down of channel powers as wavelengths are brought into and taken out of service

These control decisions are translated into commands that are communicated to the managed elements for execution. This ongoing control loop allows the proNX Optical Director to deliver optimal optical transmission performance for the managed elements by dynamically and automatically controlling all aspects of optical link output.

High Availability Requirements for the ProNX Optical Director

In this release, 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.
