Which type of fiber cable is best suited for Telecom FTTx deployments?

Singlemode fiber is best suited for Telecom FTTx (Fiber to the x) deployments primarily due to its ability to transmit data over long distances with minimal signal loss and higher bandwidth capabilities. In FTTx applications, such as FTTH (Fiber to the Home), FTTC (Fiber to the Curb), or FTTN (Fiber to the Node), the demand for high data rates and long transmission distances is critical, and singlemode fiber excels in these areas.

Singlemode fiber cables have a smaller core diameter, which allows only one mode of light to propagate. This minimizes modal dispersion, which is a form of signal distortion that can occur in multimode fibers as light travels through various paths or modes. The lower levels of signal distortion result in the capability of conveying signals over much longer distances without the need for repeaters or amplifiers.

Moreover, the high capacity for bandwidth makes singlemode fibers ideal for supporting modern communication technologies, including high-speed internet, video streaming, and voice over IP (VoIP) services, all of which are essential for modern telecom networks. This characteristic aligns perfectly with the requirements of FTTx deployments that often serve a large number of users over significant distances, thus ensuring the efficiency and reliability of the network
