| 20090067849 | Intelligent pluggable optical transceiver - The present invention is to provide an intelligent pluggable transceiver improving an EMI tolerance with a simple mechanism. The optical transceiver of the invention comprises upper and lower housings ( | 03-12-2009 |
| 20090080897 | BI-DIRECTIONAL OPTICAL MODULE COMMUNICATING WITH SINGLE FIBER - A bi-directional optical module with an improved arrangement of the PD and the LD is disclosed. The LD is mounted on the stem through the LD carrier and the metal block, while the PD is mounted on the stem through the PD carrier. The bottom level of the PD is lower than the top level of the metal block and the top level of the PD is lower than the top level of the LD carrier. | 03-26-2009 |
| 20090296350 | HEAT-DISSIPATING MECHANISM IMPLEMENTED IN CAGE FOR OPTICAL TRANSCEIVER - A mechanism for the heat sink to adhere to the transceiver inserted in the cage is disclosed. The heat sink provides a guide in the side thereof, while, the cage provides a slit in the side. A pair of elastic tabs is diagonally formed in the slit. The transceiver slides the heat sink rearward as the insertion thereof into the cage, then, the guide of the heat sink slips down the rear tab in the slit, which presses the heat sink downward to adhere to the transceiver. The heat conducting path from the transceiver to the heat sink is formed. | 12-03-2009 |
| 20090296351 | MECHANISM TO MAKE A HEAT SINK IN CONTACT WITH A PLUGGABLE TRANSCEIVER, A PLUGGABLE OPTICAL TRANSCEIVER AND A CAGE ASSEMBLY PROVIDING THE SAME - An inventive heat-dissipating mechanism between the pluggable optical transceiver and the heat sink with the thermo-conducting sheet is disclosed. One of the optical transceiver and the heat sink is adhered with the thermo-conducting sheet. The heat sink is assembled with the cage so as to be movable in vertical as causing the downward force. The optical transceiver provides a projection in the surface to be come in contact with the heat sink, while, the heat sink provides a rail with a pocket. When the transceiver is inserted into the cage, the projection first runs on the rail to lift the heat sink upward; subsequently, is fallen within the packet to adhere the thermo-conducting sheet to the transceiver. | 12-03-2009 |
| 20100178061 | OPTICAL MODULE IMPLEMENTING A LIGHT-RECEIVING DEVICE AND A LIGHT-TRANSMITTING DEVICE WITHIN A COMMON HOUSING - A bi-direction optical module with an arrangement to reduce the crosstalk noise is disclosed. The optical module comprises a laser diode (LD) driven by a differential signal and a photodiode (PD) on a single package. The PD is mounted on a position where the electrical potential measured from respective interconnections connected to the anode and to the cathode of the LD becomes the midpoint of the interconnections. The capacitances with respect the stem, where the LD and the PD are mounted thereon, viewed from the anode and the cathode of the LD becomes substantially equal to each other, or distances from the PD to respective interconnections are adjusted depending on the length of the interconnection facing the PD. Twisting the interconnections to the LD may be effective to reduce the crosstalk. | 07-15-2010 |
| 20110064364 | OPTICAL TRANSCEIVER WITH ENHANCED EMI TOLERANCE - An optical transceiver with an enhanced EMI shielding is disclosed. The optical transceiver of the invention provides an optical receptacle made of metal and an optical subassembly with a metal cover assembled with the optical receptacle. The metal cover electro-magnetically divides the inside from the outside of the transceiver. The metal cover provides a plate portion and an edge portion, where the former portion forms an opening through which the sleeve passes without coming in contact with the metal cover, while, the latter of which comes in contact with the receptacle. | 03-17-2011 |
| 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 |
| 20110255831 | PLUGGABLE OPTICAL TRANSCEIVER HAVING INNER OPTICAL CONNECTION 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. | 10-20-2011 |
