Table 5: Parameter Definitions and Ranges

Parameter

Definition

Range

chassis

The chassis number.

See Chassis Number Ranges.

slot

The slot within the chassis.

See Slot Identifier Ranges.

subslot

The subslot identifier within the module.

See Subslot Identifier Ranges.

port

The port identifier within the subslot or module.

See Port Identifier Ranges.

subport

This applies to UFM6 only.

In port group 1, depending on the transceiver, each port can be physically divided into subports using a fiber breakout device. These subports connect to external equipment.

In port group 2, the conceptual 400-Gbps port is divided into two physical subports on the UFM faceplate.

UFM6:

  • Port group 1 subports: 1 through 4

    Note: Subports 2 through 4 are only applicable for transceivers that require a fiber breakout device.

  • Port group 2 subports: 1, 2

channel

The meaning of an optical channel depends on the context:

  • UFM6: The optical channel in a subport in port group 2

  • ROADM: The optical channel that bears user traffic.

UFM6:

  • Optical channel in a subport in port group 2: 1

ROADM:

  • Alphanumeric string up to 32 characters long

tributary

This parameter specifies the tributary within an optical channel on a UFM6.

A tributary is a signal that is modulated onto an optical channel. Each optical channel on a UFM6 can carry up to two OTU4 tributaries.

UFM6:

  • Port group 2 subport optical channel OTU4 tributaries: 1, 2

subinterface

A subinterface is a lower-order ODU multiplexed within a higher-order ODU. ODU4 signals on all UFMs can be configured to contain multiplexed lower-order ODUs.

UFM3, UFM4, UFM6:

  • ODU2 subinterface within an ODU4: 1 through 10

  • ODU2e subinterface within an ODU4: 1 through 10

group

This parameter specifies the protection group for WPS.

WPS:

  • WPS group: 1 through 4
