Abstract
(EN)
The present application relates to an optical module, comprising a circuit board, a laser transmitter, and a first laser receiver. A surface of the circuit board has gold fingers, a control chip, a first drive chip, and a second drive chip. The first drive chip is connected to a transmission pin of the gold fingers. The second drive chip is connected to the control chip. The first drive chip and the second drive chip drive, in a time division manner, the laser transmitter to generate laser light having a first wavelength, and the laser light enters an external optical fiber, wherein the transmission pin provides transmission data to the first drive chip. The first laser receiver receives reflected light having the first wavelength from the external optical fiber. The first drive chip and the second drive chip in the present embodiment share the laser transmitter to achieve the effect that functions of the optical module all have a laser transmitter emitting light, thereby reducing required lasers by one, and reducing the volume and the package size of the optical module.

La présente invention concerne un module optique, comprenant une carte de circuit imprimé, un émetteur laser, et un premier récepteur laser. Une surface de la carte de circuit imprimé comprend des doigts d'or, une puce de contrôle, une première puce de commande, et une seconde puce de commande. La première puce de commande est connectée à une broche de transmission des doigts d'or. La seconde puce de commande est connectée à la puce de contrôle. La première puce de commande et la seconde puce de commande commandent, par répartition dans le temps, l'émetteur laser afin de générer une lumière laser comprenant une première longueur d'onde, et la lumière laser entre dans une fibre optique externe, la broche de transmission fournissant des données de transmission à la première puce de commande. Le premier récepteur laser reçoit une lumière réfléchie comprenant la première longueur d'onde à partir de la fibre optique externe. La première puce de commande et la seconde puce de commande partagent l'émetteur laser afin d'obtenir l'effet selon lequel les fonctions du module optique comprennent toutes un émetteur laser émettant de la lumière, réduisant ainsi les lasers requis par un, et réduisant le volume et la taille du boîtier du module optique.
