MacArtney in 1986, developed the OptoLink underwater multimode optical fiber connectors, in 1996 and developed a single-mode optical fiber connector, underwater OptoLink using extension type connection technology, docking with the other company USES optical fiber type connection technology, compared the new connection technology is more adapted to the Marine environment application requirements, simplify the maintenance work, effectively reduce the caused by fiber core docking and wear of the optical fiber transmission failure, has greatly increased the number of the connector plug.

Optical fiber connector flange socket (FCR), round (BCR) and fiber plug socket (CCP, CCR), after the connections reduced to small insertion loss, return loss and control to the very small to fit the application of high power laser source launcher, work depth of 6000 m water depth, aluminum nickel/copper alloy or stainless steel 316 do shell material, material inventory stock connectors.

It has been successfully applied to the project of "15" 863 project "high resolution sfa-side-swept sonar system" and Shanghai jiaotong university's ten-thousand-meter optical drag body.
