Product Overview
An integral part of Juniper’s
Programmable Photonic Layer
open line system solution, the
TCX Series Optical Transport
Systems portfolio provides the
foundation of a comprehensive,
open, and programmable packet
optical transport network. The
TCX1000 Programmable ROADM
works alongside TCX1000
amplifiers and multiplexers to
deliver the essential elements of
an open line system, supporting
numerous use cases that help
network operators address new
market opportunities in cloud, 5G,
Internet of Things, multigigabit
broadband access services, and
high-capacity wholesale services,
among other offerings.
Product Description Juniper Networks® TCX1000 Programmable ROADM is a colorless, directionless,
reconfigurable optical add/drop multiplexer (ROADM) that scales up to 25.6 Tbps per line.
The flexible-grid ready TCX1000 provides long-term investment protection for customers,
and supports a diverse range of packet optical network use cases.
Designed from the ground up as an open platform, the TCX1000 disaggregates the line
system from the optical transponder layer, freeing network operators to select and deploy
transponders—whether from Juniper or a third-party solution—that best fit their network
requirements and budget.
Unique to Juniper, TCX1000 Programmable ROADM control software is fully disaggregated
from the system hardware, optimizing line-system performance and allowing the control
plane to be modified—including software upgrades and updates—with far greater simplicity,
flexibility, and service continuity than currently possible with mainstay line systems.
All hardware in the Juniper Networks TCX Series Optical Transport Solutions portfolio is
managed by Juniper Networks proNX Optical Director, which is an open, microservices-
based optical network management and control platform.
Serving as a massively scalable foundation for packet optical transport networks, the
TCX1000 Programmable ROADM is an ideal complement to several Juniper solutions,
including Data Center Interconnect (DCI), metro aggregation, submarine landing terminal
backhaul, and Converged Supercore® transport.
Architecture and Key ComponentsIn addition to the Programmable ROADM platform, the TCX1000 line includes a
96-channel fixed multiplexer, an inline amplifier, and a 2-degree, 8-channel multiplexer
that work together to deliver a comprehensive programmable photonic layer solution.
Hardware
With the TCX1000 Programmable ROADM, Juniper has established a new standard for
open, programmable, and disaggregated line systems, coupling line system hardware with
Juniper software to help customers lower TCO and accelerate network innovation.
The TCX1000 Programmable ROADM is part of Juniper’s Programmable Photonic Layer
open line system, offering a 20-port open ROADM that can reach distances of up to 3800
Colorless multiplexing: The TCX1000 provides two solutions
for colorless and flexible grid multiplexing in the form of a
transponder-direct connection to the ROADM or an 8-way
passive multiplexer.
The direct connect provides a simple way to offer up to 20
colorless connections. The transponder is directly connected
to a TCX1000 Programmable ROADM port and the channel is
provisioned without requiring any additional external multiplexer.
The TCX1000 2-Degree, 8-Channel Multiplexer is a passive
splitter that acts as a simple port multiplier. One of the
multiplexer’s two common (line) ports is connected to one of the
TCX1000 Programmable ROADM ports allowing up to eight more
transponders to be connected to the TCX1000 Programmable
ROADM while maintaining spectrally programmable (colorless)
operation. Connecting 12 multiplexers, for instance, would
allow a single TCX1000 Programmable ROADM to support 96
transponder connections while leaving eight ROADM ports free
for a 9-degree ROADM configuration; attaching 16 multiplexers
would provide 128 transponder connections, leaving four ports
available to support a 5-degree ROADM configuration.
Inline amplifier: Inline amplification provides a low-cost, low-noise,
high-density amplification solution for sites that do not require
access to traffic on the line. The TCX1000 Inline Amplifier (ILA)
provides gain-flattened amplification, with the ability to tilt the
spectrum for coarse spectrum equalization. The ILA embeds an
OSC solution that provides a 100 Mbps Ethernet channel on a 1511
nm carrier; this is compatible with the TCX1000 Programmable
ROADM optical supervisory channel, which provides the ability to
access ILA nodes remotely using in-band management—required
for ILA sites where DCN access may be limited.
Figure 5: TCX1000 Inline Amplifier (ILA)
When coupled with multiple multiplexing strategies and the
extended reach enabled by the ILA, the TCX1000 Programmable
ROADM enables operators to address multiple use cases,
including point-to-point coherent access, metro and long haul
DCI, meshed coherent DCI, and metro regional and coherent
core interconnect.
Software
The TCX Series products, including all elements of the Juniper
Programmable Photonic Layer open line system, are managed
by proNX Optical Director, a microservices-based optical
network management and control platform that supports the
following features:
• Disaggregated management and control planes
• End-to-end service activation and monitoring
• Interoperability at the transponder level as well as alien
wavelength level
• Standards-based Network Configuration Protocol
(NETCONF) and telemetry interfaces
Open APIs allow customers to deploy their own network
applications, helping them build a multilayer optimized converged
packet optical network across dense wavelength-division
multiplexing (DWDM) links on Juniper Networks PTX Series Packet
Transport Routers, MX Series 3D Universal Edge Routers, QFX Series
Switches, and BTI Series Packet Optical Platforms.
The TCX Series delivers a software-managed and disaggregated
optical control plane in conjunction with optical hardware to
build next-generation transport networks, giving operators the
flexibility to deploy DWDM transponders that can be integrated
into Juniper routers, separated into standalone solutions, or
carried as alien wavelengths.
