This topic provides an overview of the ACX6160 transponder and its features.
Table 1: ACX6160 Client and Line Ports
Note: This release supports only 4 Client ports.
Interface Types Supported on Client and Line Ports
It’s important to understand, in Open ROADM, Ports and Interfaces are two distinct entities.
Ports are the physical ports on the device, in this case, the Client and Line ports on the ACX6160 front panel.
Interfaces are configured on a supporting physical port (Client and Line). or another supporting interface.
The ACX6160 has eight Client ports (labeled
0/7 on the front panel) that support
QSFP28 transceivers. These transceivers provide a speed of up to 100
Gbps, through four 25 Gbps channels. By default, Client ports are
configured as 100 Gigabit Ethernet ports.
The ACX6160 has four Line CFP2 ports (labeled
1/3 on the front panel) that support
C form-factor pluggable type 2 transceivers.
The Client and Line ports on the ACX6160 use pluggable optics, enabling you to run various interface types on the ports. All Client ports use pluggable QSFP28 transceivers that are 100 Gbps. All Line ports use pluggable CFP2-DCO transceivers that are 100 Gbps and support HGFEC.
Table 2 describes the various interfaces available for the ACX6160 Client and Line ports and the Management port, which is (1000BASE-T).

This section describes the features of the ACX6160.
Open ROADM Compliance
The ACX6160 is an Open ROADM Multi-Source Agreement (MSA) compliant device. This means it complies with the specifications described in the agreement for transponder devices. It is compatible with other devices that comply to this agreement and with Open ROADM controllers.
The Open ROADM MSA device model is a management model defined by the Open ROADM organization. Its goal is to provide a common management model to simplify the management of multi-vendor optical network architectures. It defines optical interoperability requirements for the device hardware Reconfigurable Optical Add/Drop Multiplexers (ROADM), transponders and pluggable optics) and a NETCONF API that uses Yet Another Next Generation (YANG)-based data models that abstract the management, control and provisioning of multi-vendor optical devices.
Pluggable Optical Transceivers
The ACX6160 uses pluggable optics for both the Client and Line ports. The eight Client ports use QSFP28 (100 Gbps) pluggable transceivers and the Line ports use CFP2-DCO (100 Gbps) Coherent DWDM pluggable transceivers with HGFEC support.
Only Juniper Networks branded transceivers are supported on the ports of the ACX6160. The Juniper Part Number (JPN-SKU).
The ACX6160 includes a rich set of performance monitors that monitor the health of the device and notify you of any problems. It includes both current and historical performance monitoring and supports the Open ROADM YANG models for both currentPmlist and historyPmlist.
The ACX6160 supports the performance monitoring capability per the Open ROADM MSA specification version 2.00, release 2 Device white paper v0.3.
The ACX6160 supports one-touch provisioning. All that’s needed to deploy it, is to bring it to the site, cable the device Ethernet (1000BASE-T) management port to the LAN on which your Open ROADM controller resides, cable the device power and power it up. The ACX6160 automatically receives a temporary IP address from your DHCP server, which must also be on same LAN. After the controller recognizes the ACX6160 as an Open ROADM device, you can assign a permanent IP address and configure the device using your Open ROADM controller and the Open ROADM YANG data models described in this guide.
Forward Error Correction (FEC)
The ACX6160 supports HGFEC (QPSK-100G) FEC.
Configuring the FEC mode is mandatory. You must configure the ACX6160 interface for the HGFEC (QPSK-100G) FEC mode in order to activate the interface. If you do not configure it, the corresponding CFP2-DCO module is not activated
Managing the ACX6160
You can manage the ACX6160 through its NETCONF API using an Open ROADM compliant controller and the Open ROADM YANG data models described in this guide.
As an Open ROADM-compliant device, the configuration and management of the ACX6160 is controlled through the Open ROADM controller and stored in the controller server infrastructure and not on the ACX6160 itself.
You manage the ACX6160 through the Ethernet
MGMT port on the front panel. Connect this port to the same LAN that
your Open ROADM controller is on.
