Silica fiber, also known as all-glass fiber, is an optical fiber designed for use in a variety of communication systems and applications. It is composed of a core and cladding, both made of silica glass and typically covered in a polymer overcoat or buffer.
The core of a silica fiber is the innermost part of the cable which is responsible for carrying the signal. It has a small diameter and is composed of undoped silica glass. The cladding surrounding the core is also made of undoped silica glass and has a slightly larger diameter. The cladding helps to guide the signal through the fiber and reduce the amount of signal loss.
Silica fiber is suitable for a variety of applications due to its high bandwidth capacity, low signal loss, and low cost. It is often used for short and long-distance communication systems, such as phone lines, internet connections, or cable television systems. It is also used in medical imaging and sensing, as well as in optical fiber lasers and amplifiers.
The polymer overcoat or buffer surrounding the silica fiber helps to protect it from mechanical and environmental damage. It also reduces the amount of signal loss and noise, as well as providing additional strength and flexibility.
Silica fiber is a reliable and economical solution for many communication systems and applications. It has a high bandwidth capacity, low signal loss, and is protected from mechanical and environmental damage by a polymer overcoat or buffer. Its versatility and affordability make it a popular choice for many different applications.
