HDI Circuit Board - Optical module HDI PCB

Optical module HDI PCB product characteristics

1. Optical fiber circuit board ultra-small board (3-5 square centimeters);

2. High precision. Small boards of optical fiber circuit boards also need to package ICs. Some advanced ones also have blind buried holes or even HDI(some are HDI second-order).

3. The shape fit tolerance is strict, the iron shell is fixed, the small card is not tight, and the large card is not loose. (Controlled according to Level 3 standards)

4. The PCB optical fiber board adopts long and short golden finger technology.

5. Rogers and Panasonic M6 materials are commonly used for optical fiber PCB boards.

5G will drive demand for nearly 250 million core kilometers of optical cables. It should be noted that there are great uncertainties in the current 5G transport solution, including the deployment proportion of c-ran and the proportion of forward wavelength division equipment. Actual fiber demand is likely to be much lower than forecasts.

In the 5G era, if SA networking is adopted, in addition to the forward network, the backhaul network and bearer network also require a large number of optical fibers. Consumption is expected to exceed market expectations by about 100 million core kilometers. The industry is expected to see a marginal improvement.

The 5G access network architecture will become a three-layer cu-du-aau architecture, and the demand for optical modules will further increase. It is estimated that the total demand for 5G front and mid-transmission modules in my country is about 40.8 million and 13.6 million pieces, which is 2.67 times the demand in the 4G era.

Optical modules are composed of optoelectronic devices, functional circuits and optical interfaces. Optoelectronic devices include transmitting and receiving parts.
