An apparatus for an attenuation adjustment tool, the attenuation adjustment tool includes a body with an adjustment arm positioned at a first side of the body, where an actuator is configured to extend and retract the adjustment arm. The attenuation adjustment tool further includes an input port and an output port positioned at the first side of the body, wherein an input prong and an output prong of a wrap plug are each respectively insertable into the input port and the output port. The attenuation adjustment tool further includes the adjustment arm configurable to engage with a mechanism on the wrap plug, wherein the mechanism is configurable to alter a shape of a signal cable in the wrap plug.

An adjustable attenuation wrap plug for insertion into a signal port at an end product includes a housing with a protruding input prong and output prong, wherein a signal cable is coupled to the input prong and the output prong. The adjustable attenuation wrap plug further includes a ratchet mechanism at least partially disposed in the housing, wherein the ratchet mechanism is configurable to alter a shape of the signal cable.

An optical processing structure of an optical fiber, includes: an optical fiber that includes a core, a cladding, and a coating, the coating being partially removed; and a thermally conductive protective material made of a silicone-based thermally conductive compound and provided around the cladding in a coating removed region of the optical fiber. Further, the thermally conductive protective material contains a filler having a refractive index higher than a refractive index of the cladding, and the filler is present in a region where evanescent light seeping out of the cladding is present when cladding mode light propagating in the cladding is totally reflected.

A fiber-separation tool including a body with a channel located on a face of the body. The channel is defined by a first sidewall and a second sidewall. The channel is configured to receive an optical fiber ribbon. And, the fiber-separation tool comprises a first blade disposed in the channel with a cutting edge of the first blade. The first blade is configured to separate the optical fiber ribbon into a first portion comprising a first number of optical fibers and a second portion comprising a second number of optical fibers as the optical fiber ribbon is conveyed through the channel.

Handheld tools are provided for removing a wire from within an optical cable. For example, the handheld tool may be used to remove a copper wire from a fiber optic drop cable in an efficient manner without damaging other components of the fiber optic drop cable. Advantageously, the optical cable may be used immediately after the wire is removed without further steps by the technician, such as re-applying an outer protective sleeve, as is commonly required with known tools.
