A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated and an optical state detector. The optical state detector obtains electromagnetic radiation from the internal volume while the internal volume is EMI isolated and makes a determination that a device disposed in the internal volume has an optical state associated with the electromagnetic radiation.

A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated. The data processing device further includes an electromagnetic radiation (EMR) suppressing vent that defines one wall of the internal volume. The data processing device further includes a wireless system. The wireless system includes a first portion that is disposed in the internal volume. The first portion receives network data units from EMI emitting devices disposed in the internal volume and a second portion of the wireless system. The second portion is disposed outside of the internal volume and obtains the network data units from the first portion using a wireless connection that utilizes a transmission path that traverses through the EMR suppressing vent.

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.
