A control system for electrical devices in a vehicle has solid state output/relay (12) modules with processing and memory capability. The output/relay module (12) is programmable to store configuration data corresponding to predetermined states for the various devices to be controlled. The output/relay (12) module has memory capability including a non-volatile component (EEROM, 47). A solid state input module also has processing capability, and includes memory capability. The input module has selector switches for preselecting a variety of device states. The input module further provides a visual indication of the states for these devices. A data bus (203) provides communication between said input and output modules, and a dongle (201) is selectively connected to said relay module data bus (203) for allowing changes to the configuration data (217) stored therein. The dongale (201) is programmable from a personal computer or work station.

A cord storage device has a base member with two sides, and a plug receptacle extending from one side. The plug receptacle anchors a plug end of an electronic device cord and forms a core about which the cord can be wound. A flexible retaining wall is coupled to the base member and moves between a closed position on the one side and an open position on the other side of the base member. In the closed position, an annular space is formed for the wound cord.

A fiber optic network for a multiple dwelling unit (MDU) is disclosed. The fiber optic network comprises a riser cable preconnectorized with a first riser optical connector. The riser cable is optically connected to a feeder cable providing optical communication service to the MDU. The riser cable has one or more preset mid-span access points along the length of the riser cable. One or more optical fibers of the riser cable extend from the riser cable at the one or more preset mid-span access points and are preconnectorized with a second riser optical connector. A payout reel is adapted to pay out the riser cable such that the riser cable extends between the lower level and at least one of the one or more distribution levels. The payout reel is adapted to store a length of the riser.

Dust caps, fiber optic connectors, fiber optic splitter modules and fiber optic connector systems including interlocking aligning features for fiber optic connector parking in fiber distribution hub networks are disclosed. According to one embodiment, a dust cap for mounting upon a ferrule of a fiber optic connector includes a sleeve extending lengthwise between opposed first and second ends. The sleeve defines a lengthwise extending bore that opens through the first end for receiving at least a portion of the ferrule. The dust cap further includes an aligning feature at the second end of the sleeve. The aligning feature includes a neck portion and an interlocking portion such that the interlocking portion has a width that is greater than a width of the neck portion. The aligning feature is configured to slidably engage with a slot of a parking clip.

A universal cable bracket for strain relieving a cable in a fiber management system includes a first portion having a cable receiving area defined therein for holding a section of an optic fiber cable with a notch to prevent postponing; a second portion having a complementary cable receiving area for the section of the optic fiber cable, the second portion being configured to mate with the first portion; a routing window defined in at least one of the first and second portions for routing a fiber of the optic fiber cable therethrough; and a sacrament assembly being configured to hold the first and second portions together and to secure the section of the optic fiber cable there between.
摘要:
There is provided fiber drop terminal (“FDT”) assemblies for providing selective connections between optical fibers of distribution cables and optical fibers of drop cables, such as in multiple dwelling units. The FDT assemblies include a mounting plate that enables the FDT to be conveniently and securely mounted to a generally vertical surface, such as a wall. The mounting plate is structured such that the base of the FDT must be removed before the mounting plate can be removed, and the cover of the FDT is structured that neither the base nor the mounting plate can be removed without first removing the cover. The cover may be selectively locked to the base and/or mounting plate with a locking fastener; therefore, only technicians able to remove the locking fastener may remove the cover, base, and/or mounting plate of the FDT assembly.
