Our OpenFabric1200™ is part of the FSP 3000 OpenFabric™ Series, a family of switchponders built for maximum openness, flexibility and scale. The new OTN-based technology enables client services to be groomed into 400Gbit/s wavelengths, maximizing fiber capacity and supporting cost-efficient coherent networks. It combines open 400Gbit/s pluggable coherent technology with OTN switching on a blade, increasing wavelength efficiency and helping network operators significantly reduce metro costs. Specifically engineered for the 400G era, the ADVA FSP 3000 OpenFabric™ features 1200Gbit/s interface capacity and supports Ethernet and OTN services from 10Gbit/s to 400Gbit/s.

Metro and aggregation networks dilemma
Ever-increasing traffic growth and the need for highest spectral
efficiency are driving the rapid adoption of high-speed coherent
wavelengths in metro and aggregation networks
However, most client services in these networks are still
100Gbit/s or below; mostly Ethernet and OTN services
What’s the most efficient way to transport low-speed services in the 400G era?

FSP 3000 OpenFabric1200™
Taking our OpenFabric™ Series to the next level
Works as add/drop multiplexer
(ADM), DWDM muxponder, or OTN
cross-connect; including ADM-on-a-
card configurations
1200Gbit/s capacity on a card with
an open design and no high-speed
backplane, and that fits in multiple
FSP 3000 chassis sizes including
ETSI-compliant shelves
Combines OTN switching with latest
DWDM pluggable coherent
technology for cost-efficient traffic
grooming into 400Gbit/s
wavelengths
Innovative Terabit switching on a blade for efficient traffic grooming
Supports multi-rate OTN and
Ethernet client services up to
400Gbit/s with a wide range of
standards-based pluggable interfaces

OpenFabric1200™ operation modes
• Client traffic is multiplexed
onto one or two high-speed
wavelengths
• Client traffic is multiplexed
onto one high-speed
wavelength
• Wavelength capacity is shared
among several nodes of a
ring, creating an ADM ring
• Multi-degree ODUk switching
• ODUx services are
redistributed (switched)
between different ports
• Non-blocking switching on
ODU0/1/2/3/4/flex layers

When to use what?
Muxponder
Add/drop multiplexer (ADM)
Wavelength #1
Wavelength #2
Wavelength #3
Wavelengths partially filled to
support predicted traffic
For applications with
unpredictable, continuously
changing traffic demands, and
low fill-in rates per node
For applications with static,
predictable traffic demands
and high fill-in rate per node
Wavelength #2
Wavelength #1
One wavelength with full
capacity usage
Eliminates wavelengths in
some areas of the network
