Hermaphroditic connectors
A hermaphroditic-style connector (Figure 8.7) has both male pins and female sockets on each connector.
Fiber-optic connectors (Figure 8.8)
There are two approaches used in connecting two optical fibers in a connector: expanded beam optics and physical contact. The expanded beam process uses ball optics to transmit light across the medium. Precise alignment is not required but the losses are higher. The physical contact approach utilizes
