Abstract

The invention discloses an ultralow speed small form pluggable (SFP) optical module. The optical module comprises an optical receiver, a comparator, a processor, a logical circuit, and an optical transmitter, wherein the optical receiver is connected with the comparator, the comparator is connected with the processor, the processor is connected with the logical circuit, the logical circuit is connected with the optical transmitter, and the processor, the comparator, and the logical circuit are all connected with an edge connector. The ultralow speed SFP optical module is applicable to power control and industrial control related ultralow speed signal transmission and photoelectric conversion devices, supports an I2C communication protocol, and supports a function of monitoring a voltage and temperature of the optical module and a power of a sending terminal.

Description

technical field [0001] The invention relates to communication, in particular to an ultra-low-speed SFP optical module. Background technique [0002] SFP is the abbreviation of SMALL FORM PLUGGABLE, which can be simply understood as an upgraded version of GBIC. SFP optical modules are widely used in the field of optical fiber communication. According to the speed, the common ones are 155M / 622M / 1.25G / 2.125G / 4.25G / 8G / 10G. These SFP optical modules can be found everywhere on Ethernet and telecom network equipment. However, in the photoelectric conversion equipment for power control and industrial control, we will find a problem. The transmission rate of power control and industrial control signals is very low, some cases are several megabits, even hundreds of Kbps, but our conventional SFP optical The minimum rate of the module can only be about 50Mbps, which is mainly limited by the bandwidth limitation of the optical receiving device and the limiting amplifier used in the op...
