Optical fiber generally divided into three layers: core, cladding and coating. The core and cladding composed of glass with different refractive indices. The fiber core is a glass with a high refractive index (silicon dioxide doped with germanium). And the fiber cladding is a silica glass with a low refractive index (pure silica). Light enters the
Heart disease is a common disease in pets, especially in elderly pets. Statistics show that the incidence of heart disease in pets is as high as 10% at the age of 5-8 years old, and rises to 30% at the age of 8-10 years old. In addition, 60% of dogs suffer from heart disease, especially dogs over 13 years old, with a prevalence rate as high as 85%,
To achieve internal optical network interconnection in data centers, optical transceiver are indispensable. With the increase in the number and density of ports. half of the cost of optical networks in data centers will occupied by optical transceivers. At present, 100G interconnection technology has widely adopted in newly built data centers
