1550 nm fiber is a type of optical fiber used in telecommunications. It is a single-mode fiber with a core diameter of 8.3 to 10 microns, and is used for long-distance, high-speed data transmission. It is also used in fiber-optic networks, such as Ethernet and FTTx. 1550 nm fiber is capable of transmitting data at speeds up to 10 Gbps, and is used in applications such as cable television, internet access, and voice over IP. It is also used in medical imaging, such as endoscopy and laser surgery. 1550 nm fiber is more resistant to signal attenuation than other types of fiber, making it ideal for long-distance applications.
