VITA 87 is an emerging standard for high-density circular MT (mechanical transfer) optical connectors, designed to accommodate the increasing demands for bandwidth and signal integrity in embedded systems. Developed by the VMEbus International Trade Association (VITA), this standard outlines specifications for circular connectors that house multiple MT ferrules, fitting within proven MIL-DTL-38999 shells. VITA 87 supports configurations with 12 to 24 fibers per MT, enhancing data throughput while maintaining a compact and rugged design. This standard is crucial for applications in defense, aerospace, and other high-performance sectors where reliable and high-speed optical communication is essential.
