How does fiber work?
Merging demand for larger and faster bandwidth connections has significantly accelerated the growth of the fiber optic cable assembly market in recent years. The fiber network assumes that very thin pieces of fiberglass are used to send light signals. The light goes to the center of the optical fiber. The core is surrounded by the sheath, an optical material attached to the core, using the “total internal reflection” technique. A primer protects the fiber from moisture or other damage. The level of protection is reinforced by the cable, which holds the fiber and reinforcement elements inside, and is covered by a jack.
Definition of Single Mode
In fiber optic communications, a single mode optical fiber (SMF) is an optical fiber designed to carry light only directly to the fiber, as you can see in the image, it’s called the transverse mode. This mode defines how the wave is distributed in space, because the waves may have the same mode, but with different frequencies. In the case with single mode fiber (SMF), there are waves of different frequencies but in the same way, which means they are distributed in space in the same way, which gives a single ray of light.
Specifications of Single Mode Cable
As mentioned before, single mode cable is designed to carry light directly to the fiber. It is a fiberglass yarn with a diameter of 8.3 to 10 microns. Through relatively narrow diameter, single mode cable propagates at 1310 or 1550 nm. Single mode is a vital part of broadband networks. Designed for long-distance data transmission, it is ideal for cable TV networks or college campuses.
