Optical transceiver structure for wired communication

Abstract

The invention relates to the technical field of optical fiber communication, and discloses an optical transceiver structure for wired communication. The optical transceiver structure comprises a base, a plurality of groups of damping springs which are arranged at equal circumference are fixedly connected to the outer side of the middle part of the upper end of the base, and first heat dissipation pipes are fixedly mounted in the upper wall and the lower wall of the inner cavity of a shell. Through the arrangement of the first heat dissipation pipes, heat conduction sheets and second heat dissipation pipes, heat in the optical transceiver can be fully conducted through the first heat dissipation pipes, the heat conduction sheets and the second heat dissipation pipes, and heat dissipation fins arranged outside the shell are used for rapid and full heat dissipation, so that the optical transceiver is ensured to work stably and adapt to the environment temperature; and meanwhile, the shell is in a sealed state, so that compared with a traditional mode that cold air enters from the bottom and hot air is exhausted from the upper part, the maintenance of the working environment of each element in the optical transceiver is facilitated, impurities such as dust and water vapor in the air cannot enter the shell, the influence on the normal work of each element is avoided, and the service life of the optical transceiver is prolonged.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical transceiver structure for wired communication. Background technique [0002] The optical transceiver generally includes an optical transmitter and an optical receiver. The function of the optical transmitter is to convert the electrical signal into an optical signal and send the optical signal to the optical receiver. The optical receiver converts the optical signal into an electrical signal and outputs it. Among them, the laser component of the optical transmitter is the core of the equipment, which requires high working conditions. If the temperature of the surrounding environment exceeds the approved temperature range, the equipment will not work normally. Do a good job of safety measures such as moisture-proof, waterproof, and dust-proof, so that the optical transceiver can work normally. [0003] However, the existing vehicle-mounted optical t...

Problems solved by technology

[0003] However, the existing vehicle-mounted optical transceivers still have some shortcomings in the actual use process: the normal operating temperature of the optical transceiver is -25°C to 70°C, so the optical transceiver needs a heat sink with good performance as a guarantee for its normal operation. Most of the technologies use the fan on the top for air cooling and heat dissipation. The external cold air is sucked in from the lower half of the equipment shell, and the hot air inside the shell is discharged from the upper part of the shell. In this heat dissipation method, the external cold air is in contact with Before the optical transceiver, it will be in contact with components such as the terminal block below the optical transceiver. The heat emitted by these components will contact the optical transceiver with the airflow, which greatly reduces the cooling effect of the external cold air on the optical transceiver. In addition , the exchange with the outside air will also cause impurities in the outside air to enter the casing, corrode electrical components, and affect the overall service life of the optical transceiver; secondly, the existing optical transceivers generally only use one side for cooling and heat generation Components, the air inlet and outlet for heat dissipation usually share one, or use two heat dissipation outlets on the same side that are close together

When sharing a cooling outlet or the distance between adjacent air inlets and outlets is very close, the positive and negative airflows are on the same side, and the heated hot air is discharged and mixed with the cold air outside, and a large part of it will be reflowed from the air inlet. The tuyere is sucked into the radiator to form a waste gas heat cycle, thereby reducing the heat dissipation efficiency of the optical transceiver
