TCX1000-RDM20 Description


The Juniper Networks TCX1000-RDM20 is a standalone 20-port programmable optical add/drop multiplexer (ROADM) with removable AC or DC power supplies and cooling fans.

The TCX1000-RDM20 provides:

  • Route and select wavelength selective switching (WSS) with 20 node-side universal ports

  • Integrated erbium-doped fiber amplifier (EDFA) line amplification

  • Integrated spectral and total power monitoring

  • Integrated Ethernet optical supervisory channel (OSC)

The 20 universal ports are used for:

  • Direct add/drop of channels on to the network. This provides single direction, colorless mux/demux ports.

  • Connection to external mux/demux common ports (such as the 96-channel fixed mux/demux module). This allows the external mux/demux to be used to multiply the ports on the TCX1000-RDM20. See the 96-Channel Fixed Mux/Demux (FMD96) for more information.

  • Connection to external mux/demux common ports on the TCX1000-2D8CMD module. This allows the external mux/demux to be used to multiply the ports on the TCX1000-RDM20. See the TCX1000-2D8CMD Description for more information.

  • Connection to other TCX1000-RDM20 to form multi-degree switching nodes.

For more information on the TCX1000 Series operation, features, and deployment examples, see the TCX Series Optical Transport System Feature Guide at

The TCX1000-RDM20 is managed by using the proNX Optical Director. For more information about configuring the TCX1000-RDM20, see the proNX Optical Director User Guide and the proNX Optical Director Installation Guide at


The TCX1000-RDM20 does not run the Juniper Networks Junos operating system (OS).

Power supplies
Grounding point

The cooling system in a TCX1000-RDM20 consists of two fan modules. These fan modules can be hot-swapped—you do not need to power off the TCX1000-RDM20 or disrupt the functioning of the TCX1000-RDM20 to replace a fan module. The TCX1000-RDM20 has two 650-W power supplies, either AC or DC depending on your configuration. The power supplies can be AC or DC. Only one power supply is required to power the device, while the second power supply provides redundancy.
