An optical module for preventing laser beam leakage and a control method thereof are disclosed. The optical module including a current control circuit, a first transistor, a laser, and a laser control unit. The laser control unit is configured to: if it is detected that an optical fiber is inserted in the optical fiber interface, perform control to turn on the laser, or if it is detected that no optical fiber is inserted in the optical fiber interface, control the laser to remain in an off state. A laser beam is effectively prevented from causing human bodily injury when an optical fiber is not inserted in an optical fiber interface.

Described are examples of optical blind-mate connector adaptors, optical blind-mate connectors to blind-mate to the adaptors, and optical blind-mate systems. In various implementations, an optical blind-mate connector adapter may include a sleeve housing and a shutter mounted at an opening of the sleeve housing. The shutter may include a shutter flap to cover the opening in a closed position and a shutter tab to receive a force to move the shutter flap from the closed position to an open position extending away from the sleeve housing.

The invention provides a dust cap which allows for performing operation test of an optical transceiver without removing the dust cap from the optical transceiver. The dust cap 100 comprises: a connector 110a having an opening on a distal end of the connector 110a, which is pressed into a transmission adapter of the optical transceiver 300; a connector 110b having an opening on a distal end of the connector 110b, which is pressed into a reception adapter of the optical transceiver 300 adjacent to the transmission adapter; a support member 140 connected with proximal ends of the connectors 110a, 110b and configured to support the connectors 110a, 110b; and an optical transmission path 130 configured to pass through the connector 110a, the support member 140, and the connector 110b in that order and to transmit light from the opening of the connector 110a to the opening of the connector 110b.

Optical fibers for delivering laser energy inside the body are often tasked with traversing tortuous routes in accessing the target tissue or pathology, e.g. ureteroscopic laser lithotripsy. A common failure in such applications, known in the field as ‘fiber burn through’, has been known to injure patients and is a major cause of damage to ureteroscopes. Where irregular output that is produced at the start of a lasing interval passes through a fiber that is at or near the optical minimum bend limit, fail safe polymer claddings are damaged and can no longer contain even regular laser output in tight deflection. The invention disclosed provides a solution to premature fiber failure and collateral damage.

A lighting device configured to accommodate an optical fiber is provided. The lighting device includes a breaking structure which accommodates a portion of the optical fiber in a state in which the portion includes two or more bends. The breaking structure is configured to break and sever the portion of the optical fiber when the optical fiber is subjected to a load of a predetermined magnitude.

There is provided a multi-clad fiber assembly for reducing and eliminating deleterious laser-contaminant interrelations, and methods of making these assemblies. There is provided an optical connector having contaminants that are shielded from causing detrimental thermal effects, during laser beam transmittion, by preventing laser-contaminant interactions.

The present disclosure relates to connector ports with shutters configured to inhibit dust intrusion by including peripheral regions that oppose undercut portions of the connector port when the shutter is closed. The present disclosure also relates to fiber optic connectors having latching configurations with double latches for retaining the fiber optic connectors in connector ports. The present disclosure also relates to a fiber optic connector including a plurality of stacked fiber carrier modules. The present disclosure also relates to a fiber optic connector including a connector body and a rear connector piece that is secured to the connector body by a snap-fit connection. The rear connector piece can be configured for attachment to a fiber optic cable. The rear connector piece can be secured to the connector body by a snap-fit connection. The rear connector piece can have a snap-fit interface compatible with a number of different styles or types of connector bodies to promote manufacturing efficiency.

There is provided an optical system comprising a light conduit. The light conduit comprises a first light pipe, a second light pipe, and a first bridge to mechanically couple the first light pipe to the second light pipe. The first light pipe has a first inlet to receive a first input light signal and a first outlet to emit at least a portion of the first input light signal to form a first output light signal. Moreover, the second light pipe has a second inlet to receive a second input light signal and a second outlet to emit at least a portion of the second input light signal to form a second output light signal. Furthermore, the first bridge has a first end mechanically coupled to the first light pipe and a second end mechanically coupled to the second light pipe.

A port protection device includes a blocking element movement subsystem that may be coupled to a port that defines a port entrance, and a port entrance blocking element connected to the blocking element movement subsystem and defining airflow aperture(s). When the blocking element movement subsystem is coupled to the port, the blocking element movement subsystem allows the port entrance blocking element to be positioned in a port protection orientation immediately adjacent the port entrance such that airflow is restricted to entering the port via the airflow aperture(s). When the blocking element movement subsystem is coupled to the port, the blocking element movement subsystem also allows the port entrance blocking element to move from the port protection orientation to a cable connector orientation in response to engagement with a cable connector so that the cable connector may move through the port entrance to connect to the port.

A coupled optic system is disclosed. The coupled optic system includes an optic system. The optic system includes a frame, one or more interface lenses, a lid, and one or more frame alignment surfaces. The coupled optic system further includes an optical connector. The optical connector includes one or more connector lenses, an optical connector holder, and one or more holder alignment surfaces. The optic system is configured to be removably couplable to the optical connector, and the one or more frame alignment surfaces are configured to be removably couplable to the one or more holder alignment surfaces.
