How Fast Fiber Optic Cable Speed Is

Recently, it is increasingly obvious that fiber optic cable is replacing the copper cable as a communication way step by step. In addition, current fiber optic cable is capable of operating at an astounding speed to meet the ever-growing demands of business infrastructure. In this article, we will demonstrate the performance of the fiber optic cable, which includes the speed introduction of single mode fiber and multimode fiber.

What is the Maximum Supported Throughput of a Cat6 Cable

The maximum supported throughput of a cat6 cable is 10Gbps. We use different types of cables to connect to different devices. Typically, the most common cable is Twisted or coaxial cable. All these are using depending on the network topology, hardware, software, or network size. All these connections belong to the physical layer. Let us know the different category cables with their maximum supported throughput. The different bandwidth separates the twisted pair into different categories and classes. Usually, there are two main standards. They are
  • ISO(International ISO standard)
  • American TIA/EIA standard
The ISO uses the classes like class A, class B, class C and so. The TIA/EIA uses CAT5, CAT5e, CAT6, CAT6e, and so on.

Fiber Optic Cable Speed Introduction

Fiber optic cable contains strands of optically pure glasses. For the glasses, they are thinner than a human hair and can carry digital information over a long distance. Digital signals are sent as pulses of light without interference or limitation. In that way, the digital transport system is faster and more reliable.Fiber optic technology enables more information to be transmitted in a shorter period than older internet technology, such as cable and DSL. The greater data rate will lead to quicker fiber optic cable velocity, greater quality streaming, and a better internet experience for internet users. Fiber optic technology allows for more data to be transferred in a shorter time than the older internet technology, like cable and DSL. For internet users, the higher data rate will lead 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 in two types: single mode fiber and multimode fiber. Under these two types, there are many sub-branches, such as the single mode LC fiber for long distance transmission and the multimode LC fiber for short distance transmission. However, they also have the respective fiber optic cable speed for distinct kinds of cables.

Single Mode Fiber Optic Cable Speed

Single mode cable is a single strand of glass fiber with a relatively narrow diameter, about 8.3 to 10 microns. Usually, it has one mode of transmission that propagates at the wavelength of 1310nm and 1550nm. When light passes through the core of a single mode fiber, the small size of the core reduces light reflections. Therefore it lowers fiber attenuation and increases the distance that signals can travel and preserve signal quality. Whether single mode fiber operates at 100 Mbit/s or 1 Gbit/s data rates, the transmission distance can reach to at least 5km. Thus it’s commonly used for long distance and higher bandwidth applications.

Multimode Fiber Optic Cable Speed

Single mode fiber and multimode fiber are capable of achieving the same speed from 1Gbps to 100Gbps. Multimode fiber is made of glass fiber with a diameter size from 50 to 100 microns. With a larger core, it can guide many modes simultaneously. This gives rise to the more data transit through the multimode fiber core. Moreover, it will bring higher light reflection, dispersion, and attenuation rates. Multimode fiber provides higher bandwidth at higher fiber optic cable speed. It is mostly used for short distance communication, such as within a building or on a campus. Typically, the multimode fiber optic cable speed and the transmitting distance limits are 100 Mbit/s for distance up to 2 km (100BASE-FX), Gbit/s up to 1000m, and 10 Gbit/s up to 550 m.

The following chart lists the transmission distance of SMF and MMF at different fiber optic cable speeds:

Recently, it is increasingly obvious that fiber optic cable is replacing the copper cable as a communication way step by step. Fiber optic cable is the fastest mode of broadband technology available today. It sets an excellent example for businesses which are looking forward to optimize their system performance with higher bandwidth. 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 speeds for both single mode fiber and multimode fiber. In addition to the fibers mentioned above, LightOptics also provides a series of single mode and multimode fiber cords as a cost-effective alternative to satisfy your needs such as LC/SC/FC/ST fiber patch cables, MTP/MPO fiber cables, ultra-high density cables.
