Abstract: Power distribution modules capable of “hot” connection and/or disconnection in distributed antenna systems (DAS), and related components, power units, and methods are disclosed. The power distribution modules are configured to distribute power to a power-consuming DAS component(s), such as a remote antenna unit(s) (RAU(s)). By “hot” connection and/or disconnection, it is meant that the power distribution modules can be connected and/or disconnected from a power unit and/or a power-consuming DAS component(s) while power is being provided to the power distribution modules. Power is not required to be disabled in the power unit before connection and/or disconnection of power distribution modules. As a non-limiting example, the power distribution modules may be configured to protect against or reduce electrical arcing or electrical contact erosion that may otherwise result from “hot” connection and/or connection of the power distribution modules.

Abstract: Fiber optic equipment assemblies employing non-U-width-sized housings supporting U-sized fiber optic modules, and related methods are disclosed. In one embodiment, the assembly may include the non-U-width-sized housing, at least one fiber optic equipment support member, and at least one U-sized fiber optic module. The non-U-width-sized housing may include an enclosure forming an internal cavity. The at least one fiber optic equipment support member may be disposed within the internal cavity and configured to support at least one U-sized fiber optic module. The at least one U-sized fiber optic module may be disposed within the at least one fiber optic equipment support member which may be disposed within the internal cavity. The at least one U-sized fiber optic module may have a height dimension wherein at least three of the at least one U-sized fiber optic module may be disposed within a U-unit height of unity.

Abstract: Embodiments include distribution in optical fiber-based distributed communications systems configured to provide digital data services and radio frequency (RF) communications services, and related components and methods. Embodiments disclosed include units that can be provided in optical fiber-based distributed communications systems that are configured to support RF communication services and digital data services. The units may also be configured to support providing distribution of power.

Abstract: A hybrid surge protector for a network interface device (NID) is disclosed. The hybrid surge protector includes a fail-safe spring connected to the ground electrode of a three-electrode gas tube. Tabs on the fail-safe spring are held away from the gas-tube end electrodes by a fusible element. The hybrid surge protector also includes metal-oxide varistor elements (“MOVs”) in contact with the gas-tube end electrodes and with the ground electrode via an MOV spring. This arrangement provides for two initial paths to ground-one path from the gas-tube end electrodes to the ground electrode through the gas tube, and another from the gas-tube end electrodes to the ground electrode through the MOVs and the MOV spring. The dominant path to ground starts as the MOV ground path but switches to the gas-tube path as the gas tube becomes activated. Another path to ground via the fail-safe spring is also available should the gas tube overheat.
