A fiber optic splitter, also known as an optical splitter, is a passive optical device used in FTTH (Fiber to the Home) systems to split a single optical fiber signal into two or more output optical signals according to a predetermined ratio.

In data centers, optical modules exist everywhere, but few people mention them. In fact, optical modules are already the most widely used products in data centers. Today's data centers are basically optical fiber interconnection, and the situation of cable interconnection has become less and less. Therefore, without optical modules, data centers cannot operate at all. The optical module converts electrical signals into optical signals at the sending end through photoelectric conversion, and then transmits through optical fibers, and then converts the optical signals into electrical signals at the receiving end. That is to say, any optical module has two parts: transmitting and receiving. The function is to do photoelectric conversion and electro-optical conversion, so that the optical modules are inseparable from the equipment at both ends of the network. There are thousands of devices in a medium-sized data center.

Fiber optic gyroscope is the fiber angular velocity sensor, which is the most promising one among various fiber optic sensors. The fiber optic gyroscope, like the ring laser gyroscope, has the advantages of no mechanical moving parts, no warm-up time, insensitive acceleration, wide dynamic range, digital output, and small size. In addition, the fiber optic gyroscope also overcomes the fatal shortcomings of ring laser gyroscopes such as high cost and blocking phenomenon. Therefore, fiber optic gyroscopes are valued by many countries. Low-precision civilian fiber optic gyroscopes have been produced in small batches in Western Europe. It is estimated that in 1994, the sales of fiber optic gyroscopes in the American gyroscope market will reach 49%, and the cable gyroscope will take the second place (accounting for 35% of sales).
