摘要： A compact multi-channel optical may include a multi-channel transmitter optical subassembly (TOSA), a multi-channel receiver optical subassembly (ROSA) and a circuit board configured and arranged to fit within a relatively small space. The multi-channel ROSA is spaced from the circuit board to allow circuit components to be mounted between the circuit board and the ROSA. The multi-channel ROSA may also be inverted and mounted proximate a transceiver top housing portion, for example, using an L-shaped ROSA support, to transfer heat from the ROSA to the transceiver housing portion. The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

摘要： A tunable laser with multiple in-line sections generally includes a semiconductor laser body with a plurality of in-line laser sections each configured to be driven independently to generate laser light at a wavelength within a different respective wavelength range. The wavelength of the light generated in each of the laser sections may be tuned, in response to a temperature change, to a channel wavelength within the respective wavelength range. The laser light generated in each selected one of the laser sections is emitted from a front facet of the laser body. By selectively generating light in one or more of the laser sections, one or more channel wavelengths may be selected for lasing and transmission. The tunable laser with multiple in-line sections may be used, for example, in a tunable transmitter in an optical networking unit (ONU) in a WDM passive optical network (PON) to select a transmission channel wavelength.

摘要： A multi-channel transmitter optical subassembly (TOSA) with an off-center fiber in an optical coupling is disclosed, and can provide passive compensation for beam displacement introduced by optical isolators. The optical coupling receptacle can include an optical isolator configured to receive a focused light beam from a focus lens within the TOSA. The optical coupling receptacle may be offset such that a center line of the focused light beam entering the optical isolator is offset from a center line of a fiber within optical coupling receptacle. Thus the optical isolator receives the focused light beam from the focus lens and introduces beam displacement such that an optical signal is launched generally along a center line of the fiber. Thus the expected beam displacement introduced by the optical isolator is eliminated or otherwise mitigated by the offset between a center line of the fiber and a center position of the focus lens.

摘要： An optical sub-assembly cartridge for use in a multi-channel receiver optical sub-assembly (ROSA) is disclosed and includes pre-aligned demultiplexing optics. The optical sub-assembly cartridge may include a plurality of sidewalls which define a cartridge body and at least partially enclose a cavity therein. A sidewall of the cartridge body may include a sidewall opening configured to allow light to enter the cavity. A first optical filter disposed opposite the sidewall opening may receive light entering the cavity and be configured to pass unassociated channel wavelengths out of the cavity while reflecting associated channel wavelengths to a mirror disposed in the cavity. The mirror may then reflect the received channel wavelengths to a second optical filter within or external to the cavity. The second optical filter may emit a narrow spectrum of channel wavelengths to a photodiode package to convert the same to a proportional electrical signal.

摘要： A multi-channel receiver optical subassembly (ROSA) such as an arrayed waveguide grating (AWG), with outputs directly optically coupled to respective photodetectors such as photodiodes. In one embodiment, the photodetectors are mounted on a photodetector mounting bar that includes a multiple conductive photodetector pads (PD pads). Each of the PD pads may be configured to receive a photodetector, and the PD pads are electrically isolated from ground such that the photodetectors are floating. The photodetector bar further includes multiple conductive transimpedance amplifier pads (TIA pads). Each of the TIA pads may be configured to receive a TIA, associated with one of the photodetectors, and to be electrically coupled to one or more ground ports of the TIA. The TIA pads are electrically connected to a common ground shared be each of said TIAs.
