摘要： An object is to be capable of housing an optical fiber that connects between components not to exceed a bending limit of the optical fiber in a housing of a pluggable optical module. A pluggable electric connector (11) is configured to be insertable into and removable from an optical communication apparatus (93). An optical output module (12) outputs an optical signal (LS1) and a local oscillation light (LO). An optical reception module (13) outputs a communication data signal (DAT) generated by demodulating using the local oscillation light (LO). A pluggable optical receptor (15) is configured in such a manner that optical fibers are insertable thereinto and removable therefrom. A first optical fiber (F11) is connected between the optical output module (12) and the pluggable optical receptor (15). A second optical fiber (F12) is connected between the optical output module (12) and the optical reception module (13). A third optical fiber (F13) is connected between the optical reception module (13) and the pluggable optical receptor (15). Optical fiber housing means winds extra lengths of the first to third optical fibers (F11 to F13) around a guide.

摘要： The present disclosure describes fusion spliced cable assemblies. An assembly may include a first and a second fiber optic cable, where an end of at least a first optical fiber from the first fiber optic cable is fusion spliced together with an end of at least a second optical fiber from the second fiber optic cable, the first optical fiber having a first length of prepared fiber extending from the spliced end of the first optical fiber to a transition point of the first optical fiber, the second optical fiber having a second length of prepared fiber extending from the spliced end of the second optical fiber to a transition point of the second optical fiber, where the transition point of the first optical fiber is a distance from the transition point of the second optical fiber, and where a total length of prepared fiber is the sum of the first length of prepared fiber for the first optical fiber and the second length of prepared fiber for the second optical fiber; a support configured to engage at least a portion of the total length of prepared fiber such that the distance between the transition points of each optical fiber is less than the total length of prepared fiber of the first and second optical fibers; and a transition housing coupled to the first and second fiber optic cables and surrounding the support. Fusion spliced cable assembly breakout kits are also provided.

摘要： A method for protecting fusion spliced optical fibers includes immersing sections of fusion spliced first and second optical fibers in a pool of molten thermoplastic material, followed by removal and cooling of liquid-coated areas, to yield a solid thermoplastic overcoating that extends over a splice joint as well as previously stripped sections and pre-coated sections of the first and second optical fibers. Optionally, a strength member may be adhered to the solid thermoplastic overcoating to provide a reinforced fusion spliced section. A strength member may include a metal rod or a secondary, thick thermoplastic coating. A fiber optic cable assembly includes a solid thermoplastic overcoating that extends over the splice joint as well as previously stripped sections and pre-coated sections of the fibers. Such coating may be formed rapidly with minimal capital expense, may dispense with the need for integrated strength members, and may provide reduced size and enhanced flexibility as compared to heat shrink protection sleeves.
