An interconnection system including a pluggable transceiver and a connector disposed in a cavity of a conductive cage. The pluggable transceiver may include a latching mechanism for locking to the conductive cage. The latching mechanism may include a pair of latches positioned on opposite sides of the pluggable transceiver. The latches may be spatially offset from each other along a longitudinal and/or vertical direction. Corresponding latching tabs in the conductive cage may be disposed in the same relationship, even in a ganged configuration when latching tabs for adjacent cavities are formed in a common wall between cavities. Cammed surfaces of a release mechanism, centered between latching edges of the transceiver latches may impart a latch releasing force at a central portion of the latching tab forcing the lathing tab back into the common wall, reducing rotational moment applied in prior designs, such as QSFP ganged cages.

A bag, or sheet, useful for preventing electronic barcode scanners from identifying unwanted labels that appear in the field of view of such a scanner, or other similar electronic reader. The invention provides a means for blocking the scanning of undesired item identifiers, such as barcodes, for products being packed then shipped while allowing specific desirable product identifiers to be read by the scanner.

In general, the present disclosure is directed to a transmitter optical subassembly (TOSA) module for use in an optical transceiver or transmitter that includes a magnetically-shielded optical isolator to minimize or otherwise reduce magnetization of TOSA components. An embodiment of the present disclosure includes a TOSA housing with magnetic shielding at least partially surrounding an optical isolator, with the magnetic shielding reflecting associated magnetic energy away from components, such as a metal TOSA housing or components disposed therein, that could become magnetized and adversely impact the magnetic flux density of the magnetic field associated with the optical isolator.

A bi-directional optical sub-assembly (BOSA) shielding structure is adapted to wrap a BOSA. The BOSA includes a body, and a first terminal group, a second terminal group, and a third terminal group that respectively protrude from different surfaces of the body. The BOSA shielding structure includes a first shielding member and a second shielding member. The first shielding member is adapted to be sleeved on a part of the body close to the first terminal group, so as to separate the first terminal group from the second terminal group and the third terminal group. The second shielding member is disposed adjacent to the first shielding member and adapted to cover the body and the second terminal group, so as to separate the second terminal group from the third terminal group.
