22、ption The parent connector for the type SG connector family is a single position plug of plug/socket connector set configuration. The plug is characterized by duplex cantilevered optical fibres located within the plug interior. Plug optical fibres flex to mate with socket optical fibre ends. Mating
23、socket optical fibres are positioned and aligned by integral V-grooves. Socket V- grooves capture, guide, and align the plug optical fibres during connector set engagement. The spring-release latch limits plug penetration into the socket; it is also a single position key preventing inverted assembly
24、. Contaminant entry is restricted by an integral plug cover and socket door. Each is normally closed when de-mated, but self-actuate to open position for single-action connector set engagement. 3 Interfaces The following figures and tables define the standard interfaces for the type SG connector fam
25、ily. The standard interfaces contained in this standard are listed in the following:61754-19-1: duplex plug connector interface 8 contact angle61754-19-2: duplex socket connector interface 8 contact angle The following connectors are intermateable: 61754-19-1 mates with 61754-19-2.
