    Optical Modules

    ROADM Family of Modules

    The BTI7800 Series ROADM family of modules provides reconfigurable optical add/drop multiplexing, reach extension, and end-to-end service management for the BTI7800 optical network.

    The ROADM family consists of ROADM modules that provide wavelength routing, EDFA line amplifier modules that provide reach extension, CFP2-format EDFA pluggable pre-amplifier modules that provide supplementary amplification for the host module, and passive multiplexer/demultiplexer modules that provide wavelength access.

    Module

    Description

    2-Port Reconfigurable Optical Add/Drop Multiplexer (ROADM2)

    2+1-port ROADM module with per-channel gain equalization and amplification for bidirectional operation over a pair of fibers. Includes support for OSC.

    Inline Amplifier (ILA)

    EDFA-based amplifier providing unidirectional amplification of a composite signal. Includes support for OSC.

    Pluggable Pre-Amplifier (PRE)

    EDFA-based pre-amplifier that plugs into the PRE slot of a host ROADM or ILA module.

    96-Channel Fixed Mux/Demux (FMD96)

    BTI7800-specific DWDM fixed 50 GHz grid 96-channel multiplexer/demultiplexer for access to wavelengths.

    2-Port Reconfigurable Optical Add/Drop Multiplexer (ROADM2)

    The ROADM2 module provides bidirectional DWDM amplification, and supports channel-level power control and channel add/drop reconfigurability. It is typically deployed at a site where up to two DWDM network spans intersect, but it can be deployed in conjunction with other ROADM modules at other sites as well. The ROADM2 module has a single bidirectional DWDM line port (L1) for connecting to one of the network spans, and two identical bidirectional client ports (C1, C2) for connecting to a second ROADM module for access to the other network span and to a multiplexer/demultiplexer for local add/drop wavelength access.

    The ROADM2 module can be used in various nodal configurations, as a terminal node that adds/drops wavelengths at the endpoint of a linear span, as a ROADM node that adds/drops and passes through wavelengths in a ring or mesh configuration, or as a line-equalizing node that equalizes channel powers at a transit site.

    The ROADM2 module supports 96 wavelengths at an ITU-T grid spacing of 50 GHz and can be installed in any traffic slot on a BTI7800 chassis.

    Inline Amplifier (ILA)

    The ILA module provides unidirectional DWDM amplification of the composite signal. The amplifiers are fully plug-and-play, and are designed to auto-configure gain and tilt levels. ILA modules continually monitor the line and adjust gain levels as needed, and interoperate with other ROADM elements to ensure end-to-end channel power control across the entire network.

    The ILA module can be installed in any traffic slot on a BTI7800 chassis.

    Pluggable Pre-Amplifier (PRE)

    The Pluggable Pre-Amplifier module is an amplifier built in a CFP2 form factor. It plugs into the PRE slot of a ROADM or ILA module and provides supplementary amplification of the incoming composite signal.

    96-Channel Fixed Mux/Demux (FMD96)

    The FMD96 module is a BTI7800-specific, passive, rack-mounted unit that is installed alongside the BTI7800 to provide local fixed grid access to all 96 wavelengths in the DWDM 50 GHz channel plan. It has a single bidirectional line port, a monitor port, and 96 bidirectional client ports with each client port carrying a different fixed wavelength.

    The module is standalone, and does not communicate with the CMM on the BTI7800 (and therefore cannot be managed using the CLI), but it can be represented as part of a ROADM node. Although it is passive, the FMD96 contains functionality that allows the connected BTI7800 ROADM module to detect its presence.

    Provisioning a ROADM Module

    Use this procedure to add a ROADM module to a chassis.

    If auto-provisioning is enabled and you do not want to pre-provision, then you can skip this procedure because the system automatically provisions the ROADM module when you insert the ROADM module into the chassis.

    1. Enter configuration mode.
      bti7800# config
      bti7800(config)#
    2. Add the ROADM module

      For example, the following adds a ROADM module to chassis 1 slot 11:

      bti7800(config)# equipment chassis:1 module roadm:1/11
      bti7800(config-module-roadm:1/11)# 
    3. Specify the type of ROADM module you are adding.

      For example, to add a ROADM2 module:

      bti7800(config-module-roadm:1/11)# roadm-card-type 2-port
    4. Apply the provisioning.
      bti7800(config-module-roadm:1/11)# commit
      Commit complete. 

    After the provisioning is applied, the following is automatically performed:

    • The PEC is set based on the ROADM card type.
    • All ports on the module are created.
    • The OMS and OSC on each client and line port are created.

    Provisioning an ILA Module

    Use this procedure to add an ILA module to a chassis.

    If auto-provisioning is enabled and you do not want to pre-provision, then you can skip this procedure because the system automatically provisions the ILA module when you insert the ILA module into the chassis.

    1. Enter configuration mode.
      bti7800# config
      bti7800(config)#
    2. Add the ILA module

      For example, the following adds an ILA module to chassis 1 slot 11:

      bti7800(config)# equipment chassis:1 module ila:1/11
      bti7800(config-module-ila:1/11)# 
    3. Specify the PEC.

      For example:

      bti7800(config-module-ila:1/11)# pec BT8A78AMPL
    4. Apply the provisioning.
      bti7800(config-module-ila:1/11)# commit
      Commit complete. 

    After the provisioning is applied, the following is automatically performed:

    • All ports on the module are created.
    • The OMS and OSC on each client and line port are created.

    Provisioning a PRE Module

    Use this procedure to add a PRE module to a host ROADM2 or ILA module.

    Prerequisites:

    • The host ROADM or ILA module is created.

    If auto-provisioning is enabled and you do not want to pre-provision, then you can skip this procedure because the system automatically provisions the PRE module when the system detects the presence of the PRE module. The system detects the presence of the PRE module in these situations:

    • The PRE module is inserted into a ROADM or ILA that is already installed in the chassis
    • The PRE module is inserted into an uninstalled ROADM or ILA that is then installed into the chassis.
    1. Enter configuration mode.
      bti7800# config
      bti7800(config)#
    2. Add the PRE module to the host module.

      For example, the following adds a PRE module to a host ILA module in chassis 1 slot 11:

      bti7800(config)# equipment chassis:1 module ila:1/11 preamplifier pre:1/11/1
      bti7800(config-preamplifier-pre:1/11/1)#
    3. Specify the PEC.

      For example:

      bti7800(config-preamplifier-pre:1/11)# pec BT8A78AMPP
    4. Apply the provisioning.
      bti7800(config-preamplifier-pre:1/11)# commit
      Commit complete. 

    Provisioning a Multiplexer/Demultiplexer Module

    Use this procedure to add a multiplexer/demultiplexer module.

    The multiplexer/demultiplexer is a passive module that is directly mounted onto a rack. It is not automatically provisioned or discovered by the system.

    1. Enter configuration mode.
      bti7800# config bti7800(config)#
    2. Add the multiplexer/demultiplexer module.

      For example, the following adds a multiplexer/demultiplexer module to logical chassis 0 slot 3:

      bti7800(config)# equipment md:0/3
      bti7800(config-equipment-md:0/3)# 

      All passive modules are added to logical chassis 0. The slot number that you choose for the new module must not be used by any other passive module.

    3. Specify the PEC.

      For example, to specify a 96-Channel Fixed Mux/Demux:

      bti7800(config-equipment-md:0/3)# pec BT8A78MD03
    4. Apply the provisioning.
      bti7800(config-equipment-md:0/3)# commit
      Commit complete. 

    After the provisioning is applied, all ports on the module are created.

    Terminal Amplifier Module

    The 96-Channel Amplifier (AMP1) is a terminal amplifier module that integrates two erbium-doped optical amplifiers to provide bidirectional amplification of the composite DWDM signal in a point-to-point bookended configuration. The amplifier is optimized for 10-Gbps, 25-Gbps, and 100-Gbps signals, and includes an embedded optical supervisory channel (OSC) used for span loss control.

    Provisioning a Terminal Amplifier Module

    Use this procedure to add a terminal amplifier module to a chassis. An example of a terminal amplifier is the 96-Channel Amplifier.

    If auto-provisioning is enabled and you do not want to pre-provision, then you can skip this procedure because the system automatically provisions the terminal amplifier module when you insert the terminal amplifier module into the chassis.

    1. Enter configuration mode.
      bti7800# config
      bti7800(config)#
    2. Add the amplifier module.

      For example, the following adds an amplifier module to chassis 1 slot 11:

      bti7800(config)# equipment chassis:1 module amp:1/11
      bti7800(config-module-amp:1/11)# 
    3. Specify the PEC.

      For example, to specify the 96-Channel Amplifier:

      bti7800(config-module-amp:1/11)# pec BT8A78AMP1
    4. Apply the provisioning.
      bti7800(config-module-amp:1/11)# commit
      Commit complete. 

    Wavelength Protection Switch Module

    The Wavelength Protection Switch (WPS4) provides four independent 1+1 revertive and non-revertive optical protection switches. It can be deployed with a variety of equipment including ROADM elements and non-equalizing terminal amplifiers.

    Provisioning a WPS Module

    Use this procedure to add a WPS module to a chassis.

    If auto-provisioning is enabled and you do not want to pre-provision, then you can skip this procedure because the system automatically provisions the WPS module when you insert the WPS module into the chassis.

    1. Enter configuration mode.
      bti7800# config
      bti7800(config)#
    2. Add the WPS module.

      For example, to provision a WPS module in chassis 1 slot 12:

      bti7800(config)# equipment chassis:1 module wps:1/12
      bti7800(config-module-wps:1/12)#
    3. Specify the PEC.

      For example, to specify a WPS4 module:

      bti7800(config-module-wps:1/12)# pec BT8A78WPS4
    4. Apply the provisioning.
      bti7800(config-module-wps:1/12)# commit
      Commit complete.
