Overview of Single Mode vs Multimode Fiber Single mode means the fiber enables one type of light mode to be propagated at a time. Single-mode optical fiber can also refer to as fundamental or mono-mode fiber, Uni-mode fiber or Single mode optical waveguide. Single-mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest typically 1300 to 1320nm. Single mode and multimode are each a type of fiber optic cable used to transmit voice or data between devices. Lots of data centers and providers will only do single mode cabling for new installs. Single-mode fiber requires a light source with narrow spectral width making single-mode transceivers and equipment more expensive. Multimode fibers have larger cores (62.5 µm or 50 µm) that guide many modes simultaneously, which means more data can pass through the multimode fiber core at a given time. Generally, single mode fibers have a small core size (less than 10 µm) that permits only one mode or ray of light to be transmitted typically 1310 or 1550nm. In multi-mode fiber, some of the light travels in a direct route while others bounce off the walls. The 3 wavelengths listed here have close to 0% … If you have any questions, call us at 201-296-0145. Some common transceivers that employ single-mode fiber are SFP-10G-LR and GLC-LH-SMD. And the transmission systems designed for use with single mode fiber will typically cost more than $ 1000. Color Single-mode fiber is usually yellow in color. This means that the core to cladding diameter ratio is 9 microns to 125 microns. The core of a multi-mode cable is usually 50/125 or 62.5/125 microns in size. For this reason, there is little light reflection created when light passes through the single mode fiber core. This will lower fiber attenuation and create the ability for the signal to travel further. A mode is a ray of light that is transmitted through a fiber optic cable. Multimode optical fiber continues to be the more cost-effective choice over single-mode optical fiber for shorter-reach applications. The optics are not compatible either. If you have very long runs or are connecting over longer distance, single mode fiber can get you 10km, 40km, 80km, and even farther. Let us take a closer look inside a fiber optic cable.
