STRADA Whisper Backplane Connector Family

Blinding Speeds

The STRADA Whisper backplane family was designed with your need for high-performing, high-bandwidth systems in mind. Its revolutionary design transfers data at blinding speeds of 25 Gbps and offers an innovative scalability up to 112 Gbps—allowing you to achieve efficient future system upgrades without costly backplane or midplane redesigns. The STRADA Whisper product family operates with extremely low noise, low insertion loss and little to no skew—all of which provide design flexibility and high design margin. The connectors are differentiated by 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.

NEW STRADA Whisper Cable Receptacle

Design for Next-Gen Data Rates

STRADA Whisper cable receptacles can allow you to start designing for up to 112G PAM4 speeds in your servers, switches and routers. These cable receptacles incorporate STRADA Whisper connectors on one end and a variety of mid-board or to I/O products on the other, bypassing the PCB and minimizing insertion loss and cross talk. Compatible with existing TE backplane, mid-board and I/O products including QSFP, Sliver and more – allowing you to easily design your next generation system architecture.


STRADA Whisper R Connectors

Critical Upgrade Path from 56G to 112G

STRADA Whisper R high-speed backplane connectors help provide a critical upgrade path from 56G to 112G, making future data center upgrades easier. A newly-optimized footprint helps ensure low cross talk noise, enables the migration path to 112G, and makes these connectors more cost-effective.

  1. STRADA Whisper DPO Connectors (English)

TE’s new STRADA Whisper direct plug orthogonal connectors are designed to help eliminate midplane connectivity, reduce costs and improve airflow in switches, servers, base stations and other types of communications equipment.

Cabled STRADA Whisper Connectors

Flexible Solutions

As PCBs become cost-prohibitive at higher data rates, cable STRADA Whisper connectors provide a flexible solution with their ability to run longer channels. By not being tied to a PCB, connection options are expanded. We offer three main cabled solutions: point-to-point cable, value-add assemblies and a full backplane/midplane solution.

Cabled STRADA Whisper also reduces insertion loss for improved channel margin and allows for more creative system architecture design possibilities. These products can support 112 Gbps PAM-4, with future expansion to 56 Gbps NRZ and 112 Gbps PAM-4. Our manufacturing process includes extensive electrical and visual checks at every step to bring you the best quality product possible.

Mechanical Robustness

Simplified Board Design

Signal contacts are arranged horizontally in highspeed 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.

The 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 un-mate condition.

Header Assembly
The header assembly features a robust housing, C-shields, and an "orphan" flat ground for complete shielding.
