First, what are EML and DML lasers?EML lasers, i.e. photoelectric modulation lasers, work based on the photoelectric effect. It modulates the amplitude and phase of the laser by applying a voltage to the semiconductor material, thus realizing high-speed optical modulation.EML lasers have the advantages of high speed, high efficiency, low noise, etc., and have a wide range of applications in the fi

Of imitate oscillograph overall structureImitate oscillograph is a kind of oscilloscope that uses imitate circuit to serve as a foundation, the component of indication weaveform is CRT picture tube (oscilloscope tube) , it is to compare a kind of commonly used real time to detect undee oscillograph.If plan institute is shown, of typical imitate oscillograph overall structure. Basically control the

With the advent of the information age, the speed and distance of data transmission are required to be higher and higher. At present, Walsun has released a new solution with ultra-low cost that can realize 100G ultra-long distance transmission - 100G QSFP28 100km optical module, which is a comprehensive upgrade on 100G ZR4 80km optical module.I. Product Overview100G ZR4 100km is designed for 100km

1、What is 400G QSFP-DD optical module?A: 400G optical module refers to the optical module products whose transmission rate reaches 400Gbps. Currently the mainstream packaging type is QSFP-DD and OSFP, QSFP-DD is a high-speed optical module interface specification, the upgraded version of the QSFP interface, support for 400G high-speed transmission. Using optical fiber as the signal transmission me
