Specifications

•
Dual polarization quadrature phase shift keying (DP-QPSK) modulation and
soft-decision forward error correction (SD-FEC) for long haul and metro applications
You can use SNMP to manage the PIC based on RFC 3591, Managed Objects for the
Optical Interface Type.
[See 100-Gigabit Ethernet OTN Options Configuration Overview.]
•
Pre-FEC BER fast reroute (PTX3000)—Starting in Junos OS Release 13.3, the 100-Gbps
DWDM OTN PIC (P1-PTX-2-100G-WDM) supports pre-forward error correction
(pre-FEC) bit error rate (BER) monitoring as a condition for MPLS fast reroute (FRR).
Pre-FEC BER FRR uses pre-FEC BER as an indication of the condition of an optical
transport network (OTN) link. When the pre-FEC BER degrade threshold is reached,
the PIC stops forwarding packets to the remote interface and raises an interface alarm.
Ingress packets continue to be processed. When Pre-FEC BER FRR is used with MPLS
FRR or another link protection method, traffic is then rerouted to a different interface.
You can optionally enable backward FRR to inject local pre-FEC status into the
transmitted OTN frames, notifying the remote interface. The remote interface then
reroutes traffic to a different interface. When you use pre-FEC BER FRR and backward
FRR, notification of signal degradation and rerouting of traffic can occur in less time
than through a Layer 3 protocol.

•
Support for configuring interface alias names (PTX Series)—Beginning in Junos OS
Release 13.3, you can configure a textual description of a physical interface or the
logical unit of an interface to be the alias of an interface name. If you configure an
interface alias, this alias name is displayed in the output of the show interfaces
commands instead of the interface name. Also, in the output of all of the show and
operational mode commands that display the interface names, the alias name is
displayed instead of the interface name if you configure the alias name. It has no effect
on the operation of the interface on the router or switch. You can use the alias statement
at the [edit interfaces interface-name], [edit interfaces interface-name unit
logical-unit-number], and [edit logical-systems logical-system-name interfaces
interface-name unit logical-unit-number] hierarchy levels to specify an interface alias.

•
Support for active flow monitoring version 9 (PTX5000 routers with
CSE2000)—Starting with Junos OS Release 13.3, Carrier-Grade Service Engine
(CSE2000) supports active flow monitoring version 9 on PTX5000 routers.
The CSE2000 is tethered to a PTX5000 router to enable active flow monitoring version
9. Active flow monitoring version 9 supports IPV4, MPLS, and IPV6 templates to collect
a set of sampled flows and send the records to a specified host.
•
SFPP-10G-CT50-ZR (PTX Series)—Beginning in Junos OS Release 13.3R3, the
SPFF-10G-CT50-ZR tunable transceiver provides a duplex LC connector and supports
the 10GBASE-Z optical interface specification and monitoring. The transceiver is not
specified as part of the 10-Gigabit Ethernet standard and is instead built according to
Juniper Networks specifications. Only WAN-PHY and LAN-PHY modes are supported.
To configure the wavelength on the transceiver, use the wavelength statement at the
