  • Patent number: 11675148
    Abstract: An optical-path-displacement-compensation-based emission optical power stabilization assembly, comprising: a laser, a lens, and an optical fiber coupling port disposed on a first substrate and a second substrate according to a preset arrangement scheme, wherein an expansion coefficient of the second substrate is larger than that of the first substrate, and the preset arrangement scheme enables initial distances between the laser and the lens, between the lens and the optical fiber coupling port, and/or between the laser and the optical fiber coupling port to differ from respective optical coupling distances from an optical coupling point by a preset value, thereby ensuring that a coupling loss on an optical path changes along with the temperature, forming a complementary effect with respect to an optical power-temperature curve of the laser, which reduces a temperature-caused fluctuation of the emission optical power of an optical assembly.

Because the modules are relatively thin and because the spacing, or pitch, between the modules can be kept very small, the system can have a very high mounting density, and consequently, a very high bandwidth.

  • Publication number: 20150036986
    Abstract: An underwater rolling seal connector assembly has releasably mateable plug and receptacle units with one or more rolling seals mounted in front faces of receptacle and plug units. The rolling seals are rotatable back and forth between a closed position sealing one or more chambers within the respective units which contain one or more contacts and an open position in which bores through the seals are open to allow contacts in one unit to pass through the seal openings and engage contact in the other unit. Actuators automatically rotate the rolling seals into the open position during mating and back into the closed position on de-mating. At least one actuator assisting device is located in at least one of the units and associated with the rolling seal in that unit to bias the seal back to the closed position during de-mating.

  • Patent number: 8931966
    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.
