A transmitter optical sub-assembly includes a body and a receptacle assembled to a front side of the body, the receptacle including a nose body, a split sleeve enclosed by the nose body, a first body disposed behind the split sleeve, and a fiber stub either glued or shrink fit or pressed fit on to the first body, a rear end of the split sleeve being slip fitted on to the fiber stub; wherein the nose body is made from deep drawing or cold forging process and is attached on to a front surface of the body.

A mechanism () mounted on a printed circuit board for insertion of a transceiver, includes a frame structure; a pair of lead screws () mounted on and turnable with respect to the frame structure; a pair of cam units each coupled to a corresponding lead screw, the cam unit being actuatable by a turning movement of the lead screw; and a rail follower () disposed between the pair of cam units and confined to the frame structure, the rail follower having a receiving room for inserting the transceiver along a first direction, the rail follower being movable by the cam units actuated by the lead screws to move along a second direction perpendicular to the first direction.

Transceiver and mechanism for receiving the same

A transceiver module includes a printed circuit board and a metal housing enclosing the printed circuit board and defining a front opening, the metal housing including a base portion and a cover portion, the base portion including two opposite side portions, the cover portion including two opposite fixing portions each engaged with a corresponding side portion; wherein each of the side portions defines a gap having an outside opening on an outside wall thereof, each of the fixing portions includes a top portion inwardly extending from a top end thereof, and the top portion is inserted in a corresponding gap.

Transceiver module having improved metal housing for EMI containment

An optical transceiver module is provided with a delatching mechanism that allows module mounting density to be increased while also providing an ergonomic solution that allows the modules to be easily delatched and extracted from their cages. The delatching mechanism is configured to perform early disengagement of the module housing from the cage by delatching the module housing from the cage after the bail has been rotated to an angle that is less than 90&#xb0;. Because delatching occurs when the bail has been rotated to a delatching angle that is less than 90&#xb0;, the modules can be more densely stored with less space between modules that are mounted one above the other than with existing solutions.

Optical transceiver module having an early-disengage delatching mechanism

An optical communications module includes a housing that accommodates at least one optical receptacle having a cylindrical connector portion. The module further includes at least one deformable constraining member made of a material having a Young's modulus that allows the deformable constraining member to take on an initial deformity upon application of a compression force, but permits only a partial reversal of the deformity upon reduction or removal of the compression force. The initial deformity is created when the deformable constraining member is pressed against the cylindrical connector portion during assembly of the module. The initial deformity includes a deformed contour portion that conforms to at least a part of the cylindrical connector portion of the optical receptacle and prevents wiggling of the cylindrical connector portion after the cylindrical connector portion is pushed during assembly into an alignment notch provided in a lower housing portion of the module.

Optical communications module incorporating a deformable constraining member for constraining an optical receptacle

An optical communications module includes a receptacle with a stop member. The receptacle has a keyway and a latchway. The keyway is configured to receive and guide a body of the connector plug in a direction along a keyway axis. The latchway is defined by a total flexure range of the flexible latch arm between a fully flexed state and a fully relaxed state. The latchway is configured to receive and guide the flexible latch arm through a range of movement having a directional component perpendicular to the keyway axis. The stop member extends from a wall of the receptacle into the latchway. The stop member is configured to restrain the flexible latch arm in a latched state between the fully flexed state and the fully relaxed state.

Low-profile optical transceiver connector receptacle

A socket is provided that is configured to be secured to a surface of a host circuit board by solder using a solder reflow process. The solder reflow process that is used for this purpose may be the same solder reflow process that is used to make electrical connections between the array of electrical contacts disposed on the lower surface of the socket and the array of electrical contacts disposed on the upper surface of the host CB. Because the solder reflow process is an automated process, the process of securing the socket to the surface of the host CB does not have to be performed manually, but can be performed automatically as part of a typical automated surface mount technology (SMT) process of the type that is typically used to mount components on a PCB.
