Abstract: A LED display structure and its display module thereof are provided. The LED display module includes a LED array, a substrate disposed below the LED array, and at least one trace configuration layer, which is disposed below the LED array and adjacent to the substrate. The at least one trace configuration layer includes a plurality of wires, and a distribution density of the wires varies according to a distance between the wires and the LED array. When the distance increases, the distribution density of the wires is denser. Otherwise, the distribution density is sparse when the wires are closer to the LED array. In view of the simulation experimental analyses of the present invention, it is believed that at least 30% of the stray light ratio can be reduced so as to enhance the LED display structure with better transparency and image quality.

Abstract: Disclosed herein is a single wavelength bi-directional optical transceiver for transmitting/receiving optical signals having the same wavelength through an optical communication system. The optical transceiver includes a transmitter including an isolator and converting an external input signal into an optical transmit signal, an optical filter reflecting some of the optical transmit signal and transmitting the other of the optical transmit signal, an optical fiber transmitting the optical transmit signal transmitted by the optical filter to a counterpart optical transceiver, a receiver receiving an optical receive signal from the counterpart optical transceiver via the optical fiber, and a body enclosing a portion of the transmitter, the optical filter, a portion of the optical fiber and a portion of the receiver.

Abstract: A latch type optical communication module is easily mounted to and detached from a system port having a cage by means of a latch. The optical communication module is provided with a latch. The latch is rotated around a hinge shaft fixed to both sides of a receptacle and engaging latch holes of ends of the latch. When rotated the latch moves latch drivers to force a slider upward, the slider raises a groove engaging a fixing tap of the optical communication module thereby allowing the optical communication module to be detached from the system port. The optical communication module can be detached from the system port without a tool or influence or adjacent an optical communication module.

Abstract: An optical communication module is provided with a platform to provide an accurate axial alignment with optical transceiving subassemblies. In the optical communication module, axes of the optical transceiving sub-assemblies are aligned by virtue of previously established axial alignment of the platform, and the platform is fixed to a main body by inserting an insertion jaw of a cover into an insertion groove formed on an upper surface of the platform. After the optical transceiving subassemblies are inserted into the platform having the axial alignment required for a system, a bonding agent is filled into spaces defined in the platform, thereby preventing the axes from deviated by an external force.

Abstract: A latch type optical communication module, designed to9 be easily mounted and detached to a system port having a cage by means of a latch. The optical communication module is provided with a latch: The latch may be rotated around a hinge shaft fixed to both sides of a receptacle while being inserted into latch holes penetrating both ends of the latch. When the latch is rotated and then allows latch drivers to force a slider upward, the slider raises a fixing tap of the optical communication module inserted into the system port, thereby allowing the optical communication module to be detached from the system port. With the construction of the optical communication module, the plurality of additional components are not required for the optical communication module, thereby lowering manufacturing costs, and the optical communication module can be detached from the system port without any tool and any influence against adjacent optical communication module.
