A system includes one or more current sources configured to couple to an AC to DC power converter without a DC-to-DC converter between the current sources and the power converter. Each of the current sources includes a high voltage switch and one or more independent safety shutoffs. The one or more safety shutoffs are configured to disable emission of electromagnetic radiation from a laser module when triggered. A current source controller coupled to the safety shutoff(s) is configured to generate enabling signals that enable normal current source operation. The controller includes circuitry configured to measure power across the high voltage switch when the controller instructs the high voltage switch to turn off to determine proper operation of the safety shutoff(s).

High powered laser electronics

A laser system includes a high voltage AC-to-DC power converter and one or more current sources coupled to the power converter without a DC-to-DC converter between the current sources and the power converter. Each of the current sources includes a high voltage switch and one or more independent safety shutoffs. A laser module is operably coupled to the one or more current source and configured to emit electromagnetic radiation wherein the one or more safety shutoffs are configured to disable emission of electromagnetic radiation from the laser module when triggered.

A fiber distribution hub includes a cabinet; a termination region positioned within the interior of the cabinet; at least one termination module mounted in at least one opening defined at the termination region; fiber optic connectors coupled to termination adapters of the termination module; intermediate fibers extending rearwardly of the fiber optic connectors; and a multi-fiber connector terminating the intermediate fibers. The termination module includes a housing enclosing the termination adapters. One or more termination modules can be incrementally added to the fiber distribution hub.

Fiber distribution hub with modular termination blocks

A splitter assembly may include an adapter housing configured to support an adapter to receive an optical signal from an incoming optical fiber. The splitter assembly may include a splitter module configured to couple to the adapter via a connector to receive the optical signal associated with the incoming fiber, and to make the optical signal available to an output fiber via an optical splitter.

Compact blind mateable optical splitter

Fiber distribution hub

A splitter module for a fiber distribution hub includes a main body with a first aperture configured to receive an input fiber entering the splitter module, and a second aperture configured for a plurality of distribution fibers exiting the splitter module. The splitter module also includes a fin configured to be received in a slot of a splitter tray of a fiber distribution hub, and a pin configured to engage a hole in the splitter tray. The fin is received in the slot, and the pin is received in the hole of the fiber distribution hub to couple the splitter module to the fiber distribution module.

Splitter modules for fiber distribution hubs

A telecommunications cable includes a distribution cable, a tether that branches from the distribution cable, and a tether retention block affixed to the distribution cable. The tether retention block includes a first portion and a second portion that is configured to cooperate with the first portion to secure a tether buffer tube and a strength member of the tether. Each of the first and second portions defines at least a first half-channel configured to cooperate with the first half-channel of the other portion to receive the strength member of the tether.

Fiber optic cable breakout configuration with retention block

A mid-span breakout arrangement includes a distribution cable and a tether cable. The distribution cable has a breakout access location. The tether cable is secured to the distribution cable adjacent the breakout access location. The breakout further includes at least one length of optical fiber helically wrapped around the distribution cable along the breakout access location. The length of optical fiber is coupled to the distribution cable and to the tether cable.

Mid-span breakout with helical fiber routing

The present disclosure relates to a telecommunications cable including a distribution cable and a tether that braches from the distribution cable at a mid-span breakout location. A flexible closure covers the mid-span breakout location. Within the closure, fibers are broken out from the distribution cable and spliced to fibers of the tether. The lengths of broken out fibers within the flexible closure are provided with sufficient excess fiber length to allow the closure to be readily bent/flexed in any direction without damaging the fibers.

Fiber optic cable breakout configuration with excess fiber length

The present disclosure relates to a telecommunications cable including a distribution cable and a tether that branches from the distribution cable at a mid-span breakout location. A flexible closure covers the mid-span breakout location. Within the closure, fibers are broken out from the distribution cable and spliced to fibers of the tether. The lengths of broken out fibers within the flexible closure are provided with sufficient excess fiber length to allow the closure to be readily bent/flexed in any direction without damaging the fibers.
