  • Interoperable with the CFP-100GBASE-ZR transceiver supported on the 100-Gigabit Ethernet MIC with CFP (MIC3-3D-1X100GE-CFP) on MX Series routers and the 100-Gigabit Ethernet PIC with CFP (P1-PTX-2-100GE-CFP) on PTX Series routers.

  • Interoperable with the 100-Gigabit DWDM OTN MIC with CFP2 (MIC3-100G-DWDM) on MX Series routers when the 100-Gigabit DWDM OTN MIC is configured to use SD-FEC or GFEC.

Note

The 5-port 100-Gigabit DWDM OTN PIC is not directly interoperable with the 2-port 100-Gigabit DWDM OTN PIC (P1-PTX-2-100G-WDM), but they can both operate over the same DWDM line system.

Note

The 5-port 100-Gigabit DWDM OTN PIC is designed to comply with NEBS regulations on the PTX3000 and PTX5000 routers when these routers are used in typical configurations.

In a typical configuration, a PTX3000 router supports up to eight FPCs, with up to four 5-port 100-Gigabit DWDM OTN PICs installed next to any FPC. You can install other PICs next to any other FPC.

In a typical configuration, a PTX5000 router supports up to eight FPCs, with up to eight 5-port 100-Gigabit DWDM OTN PICs in any FPC slot. You can install other PICs in any FPC slot.

To comply with EMC regulations, you must also install front doors on the PTX3000 and PTX5000 chassis. See Installing the Front Doors on a PTX3000, Installing the Front Door on a PTX5000 in a Four-Post Rack, or Installing the Front Door on a PTX5000 in an Open-Frame Rack.

Tip

You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

Note

When inserting a C form-factor pluggable 2 (CFP2) transceiver, ensure that the transceiver sits tightly in the port. You hear a distinct click sound when the latch locks into the corresponding port. The latch must be fully engaged in the corresponding port for the CFP2 transceiver to function properly. Failing to do so can result in loss of connection.

To verify that the CFP2 transceiver module is inserted properly, give a gentle pull by grasping the sides of the module. The module should sit tightly.

Note

The transceiver complies with the CFP Multi-Source Agreement (MSA) mechanical standard—transceiver weight does not exceed 210 g (7.41 oz).

LEDs

The STATUS LED is located in the center of the PIC faceplate adjacent to the link and activity LED for port 2. The link and activity LEDs are located between the ports and are numbered 0 through 4. Table 2 describes the functions of these LEDs.
