STRADA
WHISPER
Blinding Speeds
The STRADA Whisper backplane family was designed with your end customer’s need for
high-performing, high-bandwidth systems in mind. Its revolutionary design transfers data at
blinding speeds of 56 Gbps and offers unparalleled scalability up to 112 Gbps—allowing you to
achieve efficient future system upgrades without costly backplane or midplane redesigns.
Backplane Connectors
Performance Matters
The STRADA Whisper product family operates with extremely low noise, low insertion loss
and little to no skew—all of which provide system architects with design flexibility and high
design margin. Specific versions are available for 100-Ohm and 85-Ohm applications so you
don’t have to compromise on total system impedance design.
Mechanically, the STRADA Whisper connector family mirrors most high-speed backplane
connectors in the market for easy implementation. It differentiates itself through folded signal
pins surrounded by strong, protective C-shaped shields, which make the product family
one of the most robust offerings in the market. Additionally, the connector footprint keeps
crosstalk down and the overall connector design uses latest eye-of-needle (EON) technology.
Your Design Partner For 112 Gbps Architectures
To ensure smooth transitions from 10 Gbps to 112 Gbps systems using the
STRADA Whisper connector, TE Connectivity (TE) can assign a team of experts—comprised
of our best signal integrity and mechanical engineers—to help you develop a solution that fits
right into your architecture. Whether it’s traditional backplane, orthogonal midplane, direct
plug orthogonal, or a cabled-backplane system, TE can tailor the STRADA Whisper product
portfolio to best fit and enable your system architecture.

PRODUCT OFFERINGS
TE offers the STRADA Whisper
product family in multiple versions:
standard, orthogonal (for mid-plane
structures), direct plug orthogonal
(DPO) and a cabled version that
allows you to run longer distances
with lower insertion loss than PCB
materials.

Power Sum FEXT is lower than -50 dB for system
implementation at 12.5 GHz
Insertion loss is less than 1dB and linear up to 20 GHz
Individual shielded pairs offer excellent signal integrity / EMI
performance
Little to no skew through high-speed differential pairs
Common mode impedance controlled throughout the
connector, including footprint and mating interface
Superior 25-Gbps electrical performance maintained even
in a 1.5mm unmated condition
No reliance on noise cancellation, unlike some competitive
products, which can be critical in high-speed applications
and the presence of uncontrollable system skew

Six ground

Signal contacts are arranged horizontally in high-
speed differential pairs for zero skew. This makes
your board design simpler, while increasing signal
integrity performance and saving board space.
Each differential pair is surrounded by six ground
connection points.

Connector allows for 1.5mm worth of
mating separation (between both the
ground and signal) through TE’s patented
C-shaped, 360-grounding design, which
includes an extra “orphan” shield at the
bottom of the horizontal stack of contacts
for complete shielding. The 360-ground
shield provides high signal integrity margin,
(electrical margin) granting you more chip
and PCB flexibility.
C-shaped shields protrude outwards to
protect signal pins from damage.

Tabs on the sides of C-shield assure that
ground contacts have at least a 2.5mm
wipe, which helps maintain electrical
performance with
1.5mm of unmate
condition.
