20110103797 | PLUGGABLE OPTICAL TRANSCEIVER AND METHOD FOR MANUFACTURING THE SAME - A pluggable optical transceiver is disclosed. The transceiver comprises a plurality of OSAs, an optical member and a plurality of inner fibers to couple the optical member with OSAs. The inner fibers each provides an inner connector to couple with one of OSAs. The housing, which installs the OSAs, the optical member and the inner fiber, is made of metal and has a grooves into which the inner fibers is set so as to arrange them orderly. | 05-05-2011 |
20110262078 | PLUGGABLE OPTICAL TRANSCEIVER HAVING ELECTRICALLY SHIELDED RECEPTACLE, AND OPTICAL CONNECTOR INSTALLED THEREIN - A pluggable optical transceiver is disclosed. The transceiver comprises a plurality of OSAs, an optical member and a plurality of inner fibers to couple the optical member with OSAs. The inner fibers each provides an inner connector to couple with one of OSAs. The housing, which installs the OSAs, the optical member and the inner fiber, is made of metal and has a grooves into which the inner fibers is set so as to arrange them orderly. | 10-27-2011 |
20120045181 | OPTICAL TRANSCEIVER HAVING EFFECTIVE HEAT DISSIPATING PATH FROM OSA TO COVER - A heat transferring mechanism of an optical transceiver is disclosed. The optical transceiver includes a metal cover, a OSA that generate heat, and a heat conductor. The OSA has the heat transferring surface extending to a direction intersecting, or substantially in perpendicular, to the longitudinal direction of the optical transceiver. The heat conductor, which is formed only by cutting and bending of metal plate, includes a contact plate and the transfer plate in thermally contact to a heat transferring surface of the OSA and an inner surface of the metal cover to form an effective heat transferring path from the OSA to the cover. | 02-23-2012 |
20120045182 | OPTICAL TRANSCEIVER HAVING EFFECTIVE HEAT CONDUCTING PATH FROM TOSA TO METAL HOUSING - An optical transceiver having a effective heat conducting path from the TOSA to the metal housing is disclosed. The TOSA has a bottom member, on which a heat generating device such as TEC is mounted, extending to a direction perpendicular to the longitudinal axis of the metal housing. The optical transceiver further includes a block movably in contact with the bottom member of the TOSA and the inner surface of the metal housing to establish the effective heat conducting path from the TOSA to the metal housing. | 02-23-2012 |
20120269486 | OPTICAL TRANSCEIVER WITH PARTITION WALL DIVIDING A SPACE TO INSTALL CIRCUIT FROM ANOTHER SPACE FOR OPTICAL RECEPTACLE - An optical transceiver disclosed provides an OSA, a circuit board, a housing, a holder and a electrically conductive nonwoven material. The housing provides the first space that provides an optical receptacle and receives an external optical connector, and the second space within which the circuit board is installed. Two spaces are divided by a partition wall with a cut to pass the sleeve of the OSA. The nonwoven material, which is put between the partition wall and the holder, fills a gap formed between the sleeve and the cut. | 10-25-2012 |
20130136458 | OPTICAL TRANSCEIVER HAVING ENHANCED EMI TOLERANCE - An optical transceiver that attenuates the EMI radiation leaked therefrom is disclosed. The optical transceiver includes a top cover and the bottom base to form a cavity into which a TOSA, a ROSA, and a circuit are set. At least one of the top cover and the bottom base provides a combed structure in a rear portion of the optical transceiver, where the combed structure has a plurality of T-shaped fins to attenuate the EMI radiation. | 05-30-2013 |
20130279862 | OPTICAL TRANSCEIVER IMPLEMENTING WITH FLEXIBLE PRINTED CIRCUIT CONNECTING OPTICAL SUBASSEMBLY TO CIRCUIT BOARD - An optical transceiver is disclosed, where the optical transceiver includes an optical subassembly (OSA) with a bottom plate for dissipating heat and connected to an electronic circuit with a flexible printed circuit (FPC). The FPC is soldered with the side electrodes of the OSA as forming a solder fillet in the plane electrode, or the FPC is soldered with the plane electrodes of the OSA as forming the solder fillet in the side electrodes, and leaving a limited room for receiving the curved FPC in peripheries of the OSA. | 10-24-2013 |
20140219616 | PLUGGABLE OPTICAL TRANSCEIVER HAVING PULL-PULL-TAB - A pluggable optical transceiver is disclosed. The optical transceiver provides a pull-tab assembled with a body of the transceiver. The pull-tab comprises a pair of arms and a handle. The arms in an end portion thereof each provides a leg set in a guide formed in the body. Sliding the pull-tab to disengage the optical transceiver from the cage, the leg is slid within the guide to push the end portion of the arm outwardly. The handle provides in an end thereof a bar including a slope. The optical fiber pulled out from the optical connector set in the optical receptacle of the transceiver rides on the slope even when the transceiver is set in the cage by the upside-down arrangement. | 08-07-2014 |
