Multi-Source Agreement (MSA) is an agreement which often acts as a de facto Standard. This allows for competitive markets containing interoperable products such as SFP, SFP+ and QSFP-DD.

SFP

SFP/SFP+ (Small Form-Factor Pluggable) is a compact, hot-pluggable optical module transceiver commonly used in telecommunication and data communications applications.

Samtec's SFP+ cable system includes a panel mounted connector and jumper cable for high-speed applications.

QSFP

Similar to SFP/SFP+, QSFP utilizes a x4 channel configuration often over fiber. Applications typically include interfacing between network hardware.

Samtec's Flyover QSFP Systems provide improved signal integrity and architectural flexibility by flying critical high-speed signals over lossy PCB materials and directly to the panel via ultra low skew twinax cable. The ultra-high-density design includes sideband signaling via press-fit contacts to help increase airflow, and a multitude of “End 2” options allow for maximum design flexibility.

QSFP-DD

As advanced ASIC and FPGA solutions hit the market, a next generation module that overcomes the limitations of QSFP needs to perform at 50+ Gbps per channel. The new QSFP-DD standard focuses on addressing data rate bottlenecks on the front panel and between systems. 

Samtec's Flyover QSFP-DD Systems provide improved signal integrity and architectural flexibility by flying critical high-speed signals over lossy PCB materials and directly to the panel via ultra low skew twinax cable. FQSFP-DD features 8 bidirectional channels with data rates of 200Gb/s NRZ (400 Gb/s PAM4). Additionally, QSFP-DD provides backwards compatibility with all QSFP modules for increased design flexibility.

In November, we continued our mobile updates to the website, released a couple of new content experiences, and made placing sample requests even easier. Read more below on these and the rest of the major updates to Samtec.com for November 2018. Continued Improvements to our Mobil...
A joint demonstration between Samtec and eSilicon — an eSilicon 7 nm 56 Gbps DSP SerDes over a Samtec 5 meter ExaMAX® backplane cable assembly — caught a lot of attention at SC18. The demo showed a true long-reach capability with a high-performance, flexible, easy-to-configure Se...
Over the past few years, Samtec has expanded its portfolio of Characterization and Development Kits. Engineers and designers demand the best tools for system prototyping. From concept and prototype to development and production, Samtec-designed Characterization and Development Ki...
That’s shocking! Insulation Resistance and Dielectric Withstanding Voltage are two of the qualification tests that Samtec performs in-house during part qualification testing. These tests will ensure that when a connector is used in environmental conditions at the rated working vo...
As corporations worldwide become more mobile-friendly to their workforce, the Internet needs to evolve to match. This has been a huge trend in the B2C space for the last decade, and is now quickly catching up to the B2B space. We’ve seen our mobile user base grow rapidly in the p...
