Fiber Cables for Ethernet Connections

Fiber cables which are also known as optical fibers are made up of strands. These strands are made with glass or plastic and are all put together to form cables. These strands carry infrared light or laser through the cable in order to transfer data. These types of cables are commonly used and best for Ethernet connections in a business building or college campus. The reason for this is that since optical fiber retains better data transmission over shorter distances this can provide the best results. The transmission rate for these cables is 10 Mbit/s to 10 Gbit/s over a length of 550 meters.

Optical fibers are made up of three dimensions, core, cladding and buffer coating. The core of the cable is what the light passes through and the cladding protects the transfer of light. The buffer coating of the cable is what protects the entire cable with plastic. The plastic covering of the fibers is what you can see as the cable and will protect the interior if it were to become wet or exposed to other damaging elements.

There are three types of optical fiber cables which are single-mode fibers, multi-mode fibers and plastic fibers. Single-mode fibers are smaller than multi-mode fibers and use infrared laser to transmit data. Multi-mode fibers are much larger and use infrared light. The infrared light in multi-mode fibers is from LEDs or light emitting diodes. These LEDs are tiny lights inside of the core that transmit data through the cable. Plastic fibers also use infrared light from LEDs but they illuminate red light through the cable.

Types of Multi-mode and Single-mode Cables

There are many types of fiber cables available on the market. An aqua fiber cable is a multi-mode fiber patch cable which performs at speeds of 10 Gigabit/s. These cables are laser optimized multi-mode fiber (LOMMF), which means that they are backward compatible. Backward compatibility means that the even though this cable was designed for updated equipment it is still compatible with existing equipment. This can be very beneficial.

The Duplex Multi-mode Fiber Patch Cable provides higher quality data transmission with increased bandwidth. This cable is much longer than the 62.5/125 fiber but doesn't compromise the quality of transmission. This cable is most useful for narrower aperture components and multi-mode applications. Other protocols such as Ethernet, Fibre Channel, Infiniband, ATM, and Internet Protocol are also compatible with this cable. Another feature of this fiber patch cable is since the cable is multicolored, it makes it easier to find different applications in your fiber distribution system as well as find the connectors.

Another fiber patch cable which is much more cost effective is the LC/LC Duplex 9/125 Single-Mode Fiber Patch Cable. This cable also provides high transmission speed as well as high bandwidth without compromising length. This cable is designed much like the Duplex multi-mode fiber patch cable in that it is also multicolored to help with identification. Many of these fiber cables (multi-mode and single-mode) can be customized for length to accommodate equipment.
