What type of fiber optic connector was commonly used in multimode networks for military installations due to its quick-connecting feature?

The Straight Tip (ST) connector is commonly used in multimode networks, particularly in military installations, due to its favorable features for quick connection and disconnection. This connector has a bayonet-style plug, which allows for an easy and reliable connection that can be quickly engaged or disengaged without the need for specialized tools. This rapid-connect capability is particularly valuable in military operations where time is crucial, and the ability to quickly reestablish connections can significantly impact operational efficiency.

In addition to its ease of use, the ST connector is also designed to handle multimode fibers effectively, making it suitable for a range of applications within military contexts. The combination of these features contributes to its prevalence for installations where rapid deployment and connectivity are essential.
