Embodiment

[0035] Embodiment: The electrical signal enters from the TXDIP pin and TXDIN pin of the main chip GN2010D. After the electrical signal is shaped and timed by the equalizer and the first clock data recovery circuit, the distributed feedback laser driver passes the TXDOP pin and TXDON pin according to the electrical signal. The output bias current and modulation current are sent to the distributed feedback laser, and the distributed feedback laser emits laser signals according to the bias current and modulation current, and the automatic power control circuit controls the received bias of the distributed feedback laser according to the optical power of the laser signal The current, and then control the optical power of the laser signal to keep constant; the avalanche photodiode receives the laser signal and converts it into an electrical signal, which is pre-amplified through the transimpedance amplifier, and then output to the limiting amplifier for further amplification, and fin...

Abstract

The invention relates to an optical module based on XFP long distance transmission. The optical module comprises a shell. A master chip, a distributed feedback laser, an optical receiving component and an MCU controller are arranged in the shell. The optical receiving component comprises an avalanche photodiode and a trans-impedance amplifier. An equalizer, a first clock data recovery circuit, an amplitude limiting amplifier, a distributed feedback laser driver and a second clock data recovery circuit are integrated in the master chip. The previous high-cost refrigeration type laser is replaced by the distributed feedback laser, the laser driver is replaced according to the requirements and the transmission distance can be 60km so that the overall cost of the optical module can be reduced under the condition of guaranteeing the transmission distance, the design complexity can be reduced and the number of devices can be reduced, and the difficulty of the manufacturing technology can be reduced.
