Pluggable optical module and optical communication system
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.

Assembly And Method For Cleaving A Glass Body With A Laser
A cleaving assembly and a method for cleaving a glass body having a face at a desired angle greater than 0 degrees are disclosed. The assembly comprises a laser device for emitting a laser beam, a rotating device, and a positioning fixture. The rotating device has a head that rotates about a central axis that is orthogonal to the laser beam. The positioning fixture is operatively mounted to the head and centered axially along the central axis and is also rotatably driven by the rotating device. The positioning fixture has a tapered surface that is transverse to the central axis and that supports the glass body at a predetermined angle relative to the central axis. Rotation of the positioning fixture about the central axis when the glass body is exposed to the laser beam, cleaves the face of the glass body at the desired angle due to the glass body being supported transverse to the central axis.
