Multi-Mode (38)Multi-mode fiber cable is the type of optical fiber typically used to transmit data across short distances, such as across a college campus or throughout a corporate building. OM1, OM2, OM3, and OM4 fiber cables are, progressively, capable of supporting more bandwidth and/or transmitting data over longer distances. Multi-mode fiber patch cable is used as a backbone network infrastructure for its reliability, high carrying capacity, and lower power consumption.
Single-Mode (16)When setting up a network that requires data to travel over long distances, most people opt to install single-mode fiber optic cable. Single-mode Fiber Cable is designed to carry only one ray of light making single-mode extremely useful for long transmission distances (see chart below for estimated distance's). Single-mode fiber is used for its high carrying capacity, reliability, and lower power consumption. Single-mode fiber is physically like multi-mode fiber, however, the glass core is significantly smaller - usually around 10 microns in diameter - and the light source enters the core at 90 degrees. While single-mode fiber cables are physically similar to multi-mode fiber cables, the glass core is significantly smaller - usually around 10 microns in diameter - and the light source enters the core at 90 degrees. These cables are able to transmit data up to 40 miles with a bandwith of 1Gb’s. On the downside, the solid-state laser diodes typically used by single-mode cables make them two to three times more expensive than multi-mode cables. Once you decide to use single-mode cable, over a multi-mode cable, you'll then need to decide whether you need a simplex or duplex version. A simplex fiber cable has only one fiber optic strand and is typically used when data only needs to travel in one direction, such as radio, television and public announcement systems. A duplex fiber cable has two strands, which allows data to travel in both directions. Whether you need a simple one-way cable or a multi strand fiber cable, Gruber Communication Products has it all.
