8. FAQ
1. Are GPO and SMP connectors compatible?
GPO™ is a trademark of Gilbert Engineering who developed this connector. A military specification was written so the defense department could use multiple sources for this connector. Only Gilbert can call this connector GPO. Other suppliers claim their connector is equivalent and call it SMP.
2. Are GPPO and SMPM connectors compatible?
GPPO™ is a trademark of Gilbert Engineering who developed this connector. A military specification was written so the defense department could use multiple sources for this connector. Only Gilbert can call this connector GPPO. Other suppliers claim their connector is equivalent and call it SSMP, Mini SMP or SMPM.
