Latest Patents
One of Joo-Chul Cho's latest patents is titled "Method and apparatus for compensating for temperature characteristics of laser diode in optical communication system." This invention discloses a method and apparatus designed to compensate for the temperature characteristics of a laser diode used in a transmitter unit of a transceiver for optical signal transmission. The transceiver includes both the laser diode and a monitor photodiode. In this method, a modulation current is derived from an input voltage and arbitrary variables. Variations of overall modulation resistance values corresponding to an operational temperature range are evaluated based on the relationship between the modulation current and the overall modulation resistance. The overall modulation resistance values are determined according to these variations. Additionally, variations of overall bias resistance values corresponding to the temperature range are evaluated by a current Impd of the photodiode, which is derived at a specific optical power arbitrarily chosen within the temperature range. The overall bias resistance values are also determined according to these variations.
Another notable patent is the "Fastening apparatus for a pluggable optical transceiver module." This invention pertains to a fastening apparatus for a pluggable optical transceiver module, which is coupled to an optical connector and electrically connected to a cage assembly. The fastening apparatus includes a module case extending along a longitudinal direction and at least one rotational latch apparatus positioned on both longitudinal lateral surfaces of the module, designed to be latched for retaining the module. When the module is mounted along the longitudinal direction of the case, it can be released through a seesawing motion about a rotation axis provided in the interior, while pressing in a direction perpendicular to the longitudinal direction.
