SOSA™ 标准

Our long-standing leadership in technical standards, experience in critical global defense programs, and our extensive portfolio of products based on OpenVPX and SOSA, enable Elma to partner with our customers in research, development and deployment of equipment and infrastructure installed in the most demanding defense applications.

No one knows SOSA like Elma Electronic. Recent activities have brought the tri-service branches together with industry to develop the Sensor Open Systems Architecture (SOSA™) technical standard, following the Modular Open Systems Approach (MOSA). Elma is an early and leading industry participant in the development of these standards, which are based on the OpenVPX architecture. We are pioneers of and key contributors to the development of the standard, with leadership roles in several key technical committees.

Backplanes

The backplane is at the heart of it all. Excellent signal integrity design is critical to reliable and successful systems aligned to SOSA, Building on decades of backplane manufacturing experience, Elma engineers are innovation leaders in high-speed signal processing design and developed the industry’s first SOSA backplanes.

• VITA 66.4 optical, 67.1 RF and 67.3 RF/optical modules
• 1000BASE-BX and KX, 10GBASE-KX4 and KR, or 40GBASE-KR4
• Slot counts from 2 - 12
• Radial clock slot for IEEE 1588 precision timing protocol and network synchronization

The highest level of signal integrity

At speeds up to 100 Gbase-KR4, every feature of backplane design can influence signal integrity (SI) – every trace, layer separation, turn bend, via, via transition, etc. Elma’s signal integrity analysis and simulations consider every element in the channel to ensure optimal performance.

We focus on each feature individually to model the complete channel and optimize the return loss for each. Once modeled, they are concatenated together along with the trace and connector models to create the complete channel. Today’s critical high-speed systems require nothing less than reliable, repeatable solutions - every time.

System Level Channel Characterization

When designing at the system integration level, Elma uses precision probe cards for complete channel characterization between all points on the backplane.
