In recent years, it is increasingly obvious that fiber optic cable is replacing copper cable as an optimal way of communication transmission step by step. One reason is that fiber optic cable can span a large distance between local phone systems and assume responsibility of backbone for many network systems and system users, including university campuses, office buildings, industrial plants and electric utility companies. In addition, current fiber optic cable is capable of operating at astounding speed to meet the ever growing demands from business infrastructure. In this article, we are going to illustrate the fiber optic cable speed and involve the speed introduction to single mode fiber and multimode fiber.

Fiber Optic Cable Speed Introduction

Fiber optic cable contains strands of optically pure glass which is thinner than a human hair and can carry digital information over long distance. Digital signals are sent as pulses of light without interference or limitation, so the digital transport system is faster and more reliable. Fiber optic technology allows for more data to be transferred in shorter time than older internet technology, like cable and DSL. For internet users, this higher data-transfer rate leads to faster fiber optic cable speed, higher-quality streaming and a better internet experience.

Single Mode and Multimode Fiber Optic Cable Speed Introduction

Fiber optic cable comes down to being one of these two types: single mode fiber or multimode fiber. For instance, there are single mode LC fiber for long distance transmission and multimode LC fiber for short distance transmission. Certainly, different types of cable will have corresponding fiber optic cable speed as well.

  • Single Mode Fiber Optic Cable Speed

Single mode cable is a single stand of glass fiber with a relatively narrow diameter of 8.3 to 10 microns that has one mode of transmission, which can propagate at the wavelength of 1310nm and 1550nm. On that account, there is little light reflection caused when light passes through the single mode fiber core. This will reduce fiber attenuation and optimize the speed for the signal to travel further. For single mode fiber optic cable speed, no matter it supports at 100 Mbit/s or 1 Gbit/s data rate, the transmission distance can reach to at least 5 km. So it is used for long distance signal transmission.

  • Multimode Fiber Optic Cable Speed

Multimode fiber is made of glass fiber with a common diameter in the range of 50 to 100 microns and has larger core that guides many modes simultaneously. This gives rise to more transit of data through the multimode fiber core and causes more light reflection, higher dispersion and attenuation rate. Multimode fiber provides high bandwidth with high fiber optic cable speed over short distance and is mostly used for communication, such as within a building or on a campus. Typically, the multimode fiber optic cable speed and distance limits are 100 Mbit/s for distance up to 2 km (100BASE-FX), 1 Gbit/s up to 1000m, and 10 Gbit/s up to 550 m.

Conclusion

Fiber optic cable is the fastest mode of broadband technology available today. They offer commercial grade bandwidth and set an excellent example for businesses which are looking forward to optimize their system performance at the same time. In general, single mode fiber with a much smaller core gives you a higher transmission rate than multimode fiber. From this article, you would have a deeper understanding about fiber optic cable speed for both single mode fiber and multimode fiber.
