Abstract: A backlight module and a display device are provided, and the backlight module includes a light guide plate, a plurality of light-emitting components, and a frame. The light guide plate includes a first side, a second side, and two third sides. The light-emitting components are disposed on the first side, and light generated from the light-emitting components enters the light guide plate from the first side. The frame covers the second side and the third sides and includes an opening and at least one buffer portion. The light-emitting components are disposed in the opening, and the buffer portion is disposed on a side of the opening and contacts the light guide plate.

Abstract: A bi-directional fiber optic transceiver includes a laser diode, a photodiode, first and second lenses, all of which share a common linear optical axis, and a housing. The first lens may have transmission increasing film thereon. The second lens may have a reflection increasing film thereon. An optical splitter may be between the first and second lenses. The first and/or second lenses may be spherical, hemispherical or aspheric. The transceiver size is reduced so that a circuit board can accommodate more components or be smaller in size. Utilizing hemispherical lenses can greatly increase the coupling ratio of the optical links between the photodiode, fiber and laser diode. Utilizing aspheric lenses with high coupling can serve high power output requirements. Use of spherical lenses (which extend the focal length) with aspheric lenses enables LD TO assemblies in individual housings to serve in various products.

Abstract: An optical triplexer and/or optical line terminal (OLT) compatible with 1.25 and 10 Gb/s passive optical networks is disclosed. The triplexer/OLT includes an optical fiber, first and second laser diodes, a photodiode, and first and second lenses. A hemispherical lens may be at an end face of the photodiode or receiver subassembly housing. A first optical splitter is mounted between the first and second lenses, and a second optical splitter is mounted between the optical fiber and the second laser diode. The first lens and first laser diode, and the second lens and second laser diode share respective common linear optical axes. The present triplexer/OLT advantageously accords with an interface standard IEEE802.3av-2009 PRX30. In addition, the present triplexer can advantageously implement analog receiving and digital transceiving, save optical fiber resources, and provide high efficiency coupling. Thus, requirements for high power output and smaller housing outlines can be served.
