Multimode fiber optic cabling has been a part of industrial LAN, WAN, and other communication networks for many years. In recent years, communication networks have become demanding in terms of transmission distance and data transmission speed. Today, modern technology demands gigabit transmission speed, therefore administrators are switching from Fast Ethernet to Gigabit Ethernet. Single-mode and multi-mode fibers are used for transmission. Single-mode fibers are usually preferred for long-distance transmission due to their single-mode transmission, which assures minimal dispersion and attenuation. Does that mean multimode fibers are not used for long-distance transmission? Multimode fibers are also used and they can transmit signal at Gigabit speeds, too. However, there are certain challenges. The fiber suffers signal dispersion and attenuation after 550 meters due to its multiple modes of transmission. Thus, reduction in dispersion and attenuation is essential to attain Gigabit speeds up to 2 km. How is it possible? This is possible using some devices. This post discusses ways to get gigabit speed over multimode fiber cable up to 2km of transmission distance using various devices.
A Few Proven Ways to Extend Multimode Fiber up to 2km at Gigabit Speed
Typically, a multimode fiber cable offers 100Mbits/sec of speed for 2km distance, 10Gbits/sec for 550 meters distance, and 1Gbits/sec and 1Gbit/sec for 1000 meters distance. In order to get Gigabit speed for a 2km distance over a multimode cable, the following devices can be used.
- Media Converters: These devices can be used to gain Gigabit speed over multimode fiber link up to a 2km distance. How? Ideally, a converter is used for translating electric signals to optical signals and vice versa but they also act as an extended if integrated properly. Introducing fiber optic media converters after 550 meters or 1000 meters of distance transmission in a network triggers a new transmission cycle. The media converters must be connected before the dispersion length to extend the transmission distance over a multimode fiber link.
- Fiber Optic Network Extenders: The fiber optics extender kits are another option to attain gigabit speed over a multimode fiber link. The extender kit includes a transmitter, a receiver, and fiber optic cables. The transmitters and receivers are placed every 550 meters before the dispersion length and they trigger the signal for the next 550 meters where a receiver is placed. Micro-modems and routers are a popular type of fiber optic network extenders and they feature a transmitter and a receiver in the same device but on different sides.
- Fiber Optic Connectors: The fiber optics connectors are used for connecting two fibers together. The connecting activity is known as fiber splicing. Well-spliced multimode cables can run for a longer transmission distance without attenuation or dispersion.
By using the above-listed devices, you can easily achieve Gigabit speed over a multimode fiber link. However, it is essential to utilize high-quality fiber optics cables, media converters, routers, and modems to extend the transmission length of the multimode fiber cable at Gigabit speed. That is why you must source these products from trusted suppliers like VERSITRON. The company is a prominent supplier of several fiber optics products. Their products are in high demand due to high build quality and efficient performance. VERSITRON gigabit media converters, fiber optics micro-modems, and fiber extender kits are widely used to extend Gigabit speed across a multimode fiber link up to 2 km.
