Abstract

The invention discloses an optical module and an optical module chip. The optical module comprises the optical module chip, a laser emission light source, a photodiode and a transimpedance amplifier (TIA), wherein a microcontroller, a laser driving circuit and an amplitude limiting circuit are integrated in the optical module chip; and the microcontroller is in communication with the laser driving circuit and the amplitude limiting circuit by an internal bus and is used for controlling the laser driving circuit and the amplitude amplifying circuit. As an essential circuit in the optical module is integrated into the optical module chip, so that the number of the chip and elements in the optical module can not be reduced, and the cost of the optical module is lowered greatly; and as the integration degree is high, the circuit space of the optical module is saved greatly, and the interference of the circuits can be reduced.

Description

technical field [0001] The invention relates to optical fiber communication technology, in particular to an optical module and an optical module chip thereof. Background technique [0002] In the current domestic market and international market, the optical fiber communication direction of high bandwidth, high speed and multi-service integration has begun to be applied; among many solutions, the emergence of fiber-to-the-home (FTTH) is considered to be the ultimate broadband access solution. The domestic market has been widely used. [0003] Among the many FTTH solutions, PON (passive optical network) has attracted much attention and has become the mainstream optical access method at present. At present, more and more PON networks are deployed. As the core component of the PON network, the optical module is under increasing price pressure. [0004] At present, the optical module of the prior art usually includes a laser emitting unit and a laser receiving unit. The laser...
