TCX1000-RDM20 Universal Port Rules
In this release, you can use the universal ports on the TCX1000-RDM20 as follows:
Each and any universal port can be directly connected to a coherent transceiver.
coherent transceivers can be:
Compatible integrated transceivers in a Juniper Networks router or switch
Juniper Networks disaggregated transceiver such as the BTI7800 Universal Forwarding Modules: UFM3 with coherent CFP and UFM6
The TCX1000-RDM20 supports up to 20 colorless channel connections — any channel can be added on any universal port of the TCX1000-RDM20. This is enabled in conjunction with tunable transceivers.
Each and any universal port can be connected to an optical multiplexer-demultiplexer.
This enables you to use the fewest number of universal ports on the TCX1000-RDM20 and plan for future expansion.
For example, connecting your transceivers to the TCX1000-2D8CMD client ports and connecting one of its line ports to a single universal port on the TCX1000-RDM20 enables you to switch an additional 8 colorless channels on the TCX1000-RDM20, while 19 universal ports are still available for direct add/drop traffic, pass-through connections, or for additional optical multiplexers-demultiplexers. The TCX1000-2D8CMD supports colorless single and multi-direction add/drop capability.
The BTI7800-FMD96 fixed optical multiplexer-demultiplexer is also compatible with the TCX1000-RDM20. You can connect the line port of the BTI7800-FMD96 optical multiplexer to a single universal port on the TCX1000-RDM20 enabling you to support up to 96 x 200 Gbps coherent channels at 50 GHz spacing.
Ports on the BTI7800-FMD96 optical multiplexer are fixed in frequency and therefore not colorless.
Each and any universal port can be used for a pass-through connection in a multi-degree ROADM node. For a pass-through connection, you connect a universal port on one TCX1000-RDM20 ROADM degree to another universal on the another ROADM degree allowing you to pass channels from one degree to another in a multi-degree ROADM node.
