Single-mode reliable optical card-edge connector (SROC)

To help alleviate reliability and maintainability problems with optical networks in weapon systems such as the Air Force F-22 tactical fighter and the Army RAH-66 attack helicopter, a reliable, blind-mate optical connector using multi-mode fiber was developed for the Air Force by AT&T. In 1993 the final prototype was developed and tested, successfully passing the severe military test environment. It was then transitioned to the F-22 program. This connector is fine for most digital applications. The next technology step will be to develop a single-mode version of this reliable optical connector-the SROC-for digital and analog applications. There are many benefits of developing this connector so that it can be used in optical systems with laser transceivers. Higher power margins can be achieved. Greater bandwidth than that of LED systems will be attained. This paper will cover the design, development, and preliminary testing of a SROC. This will include risk issues of propagation modeling, alignment, fiber eccentricity, and polarization. A discussion of the multi-mode ROC and the planned test environment will also be addressed
