Example: Configuring Two Fiber Line Terminations Using IPLCs for Optical Amplification in a Metro Linear Packet Optical Network

 

For metro linear and metro ring topologies that require either north-south or east-west communications, you can connect two integrated photonic line card (IPLC) base modules together to form a single node with two fiber line terminations. This example shows how to configure the Junos OS to support the IPLC base modules in a Metro linear packet optical configuration for adding and dropping wavelengths to a local optical interface, and for bypassing wavelengths to another IPLC. You can set up and configure an IPLC node with two line-side fiber terminations.

Requirements

This example uses the following hardware and software components:

  • Three PTX3000 Packet Transport Routers running Junos OS Release 15.1F6

  • Four IPLC base modules

  • Compatible 10-Gigabit or 100-Gigabit Ethernet OTN PICs

For complete information on all PTX Series Packet Transport Routers hardware components, see PTX Series Packet Transport Routers.

For complete information on all PTX Series Packet Transport Routers software features, see Junos OS for PTX Series Packet Transport Routers, Release 15.1.

Before you start this procedure, complete the following tasks:

  • Install the IPLCs, FPCs, and PICs in the PTX3000 chassis.

    Best Practice

    We recommend that you place the two IPLC modules at Node B into the same FPC/PIC slot pair on the PTX3000 chassis. In this example the IPLCs at Node B are located in FPC slots 2 and 3.

  • Make all connections to and from the PICs in the PTX3000 chassis to the Add and Drop ports on front panel of each IPLC node as shown in Figure 1.

  • Connect your fiber pairs to the Line IN and Line OUT ports on the front panel of each IPLC node as shown in Figure 1.

    For simplicity, Figure 1 does not show the optical ILAs between the three IPLC nodes.

  • On Node B, connect the two IPLC modules together using the PT IN and PT OUT ports on the front panel of the IPLC as shown in Figure 1.

  • Be sure to specify wavelength values on each interface as shown in Figure 1. If you must adjust the wavelength values, make sure that you enter a value supported on the IPLC.

Best Practice

Anytime you need to disconnect or connect the fiber span from the Line IN and Line OUT ports on the IPLC module, we recommend you disable the optical supervisory channel and the erbium-doped fiber amplifiers on the IPLC.

Always refer to the PTX3000 Packet Transport Router Hardware Guide when connecting or disconnecting cables on the IPLC modules. See PTX3000 Packet Transport Router Hardware Guide.

Overview

This examples describes how to configure Junos OS to support IPLC base modules in a Metro linear packet optical deployment. The Add/Drop ports of the IPLC modules are physically connected to interfaces housed in the same PTX3000 chassis.

The IPLC modules provide the combined functionality of a 32-port Reconfigurable Optical Add/Drop Multiplexer (ROADM), optical amplification, optical equalization, and optical channel monitoring on a single card.

This procedure describes how to configure Junos OS for the IPLC modules. This is not a complete configuration and does not include full instructions for configuring the router or the associated line cards. Before you start this procedure, complete the following hardware and software tasks on the PTX 3000 router:

  • Install the IPLCs, associated line cards, and PICs into the PTX3000 chassis so that the hardware configuration matches what is shown in Figure 1. If you need to make changes to the positions of the cards in the chassis, adjust the FPC numbers referenced in Figure 1 and configure them accordingly.

    Best Practice

    We recommend that you place the two IPLC modules at Node B into the same FPC or PIC slot pair on the PTX3000 chassis. In this example the IPLCs at Node B are located in FPC slots 2 and 3.

  • Configure the associated wavelengths on the interfaces of the PTX3000 by using the following procedure:

    1. Specify the interface to configure.

      For example:

    2. Specify the wavelength value supported on the interface.

    Note

    Be sure to specify wavelength values on each interface as shown in Figure 1. If you must adjust the wavelength values, make sure that you enter a value supported on the IPLC.

  • Make all connections to and from the PICs in the PTX3000 chassis to the ADD or DROP ports on front panel of each IPLC node as shown in Figure 1.

  • Connect your fiber pairs to the LINE IN and LINE OUT ports on the front panel of each IPLC node as shown in Figure 1.

    For simplicity, Figure 1 does not show the optical inline amplifiers (optical ILAs) between the three IPLC nodes.

  • On Node B, connect the two IPLC modules together using the PT IN and PT OUT ports on the front panel of the IPLC as shown in Figure 1.

  • 3x100G of Ethernet between Node A and Node B through a multi-span link.

  • 3x100G of Ethernet between Node B and Node C through a multi-span link.

  • 1x100G of Ethernet between Node A and Node C through a multi-span link including an optical bypass at through Node B.

  • In this example:

    • Wavelengths 1561.01 and 1560.20 are dropped at Node B and are also reused in both directions (Node A and Node C).

  • Other wavelengths such as wavelength 1556.96 between Node A and Node B and wavelength 1554.54 between Node B and Node C are used in only a single direction.

  • Wavelengths used in both directions can also be configured for optical buypass if it was necessary to reduce the packet throughput between the nodes. You can configure optical bypasses through the CLI, they do not require manual connection.

  • If traffic changes, you could configure Node B with 1561.01 and 1560.20 as optical bypass and that creates an additional 2x100G between Node A and Node C, leaving only 100 Gbps of traffic to Node B (and leaving four interfaces unused).
