Advantages of SFP+ Cable Assemblies


The SFP+ cable assembly’s printed circuit paddle card has been designed to not only address the stringent mechanical inter -face requirements but also the higher-bandwidth signal integrity requirements for 10Gb/s per channel transmission.


It has also been  designed  to  accommodate  industry  defined  EEPROM  cable  signature  requirements  needs  as  well  as  address  requirements for both passive and active equalized cable assembly applications. The cable assembly also includes robust diecast covers and an EMI girdle to assure proper EMI shielding effectiveness and termination. Cable assembly removal is enabled via a user friendly pull tab.


SFP+ cable assembly


In addition, SOPTO manufactures these cable assemblies using highly controlled and stable cable assembly manufacturing processes that minimizes wire management and termination variations that can impact the performance of the cable assembly. Robust final test and quality systems assure high quality cable assemblies conforming to the high-speed electrical performance requirements in industry specifications.
