What Are Yellow Fiber Optic Cables?

Fiber Optic Cables

Yellow fiber optic cables are single mode cables, which means they transmit data through one slender string of fiberglass rather than multiple. Single mode cables are capable of near unlimited bandwidth. Learn from when you might consider investing in single mode fiber optic cable for your home or business data center.

As mentioned in our last blog, one of the most important things to learn about fiber optic cables is that they’re color-coded to identify their purpose. For example: an orange cable jacket indicates that the cord is an OM1 or OM2 cable, while yellow identifies a cable as OS1, or Single mode. Previously, we discussed multi mode orange and aqua fiber optic cables and their uses. This time we're going to take a look at yellow cables. 

When should you consider purchase single single mode fiber optic cable rather than multi mode fiber cable? You might believe that more is better, and so multi mode optical fiber will operate father and more efficiently than single mode - but you would be mistaken! Believe it or not, single mode fiber's single transmission mode is capable of carrying higher bandwidth. When it comes to transmission distance, single mode emerges the victor by a long shot - its single glass fiber strand transmit 1 to 10 gigs of data and 1080p resolution up to twice as far as OM1, OM2, OM3, or OM4 fiber optic cables.  Though a single mode cable's fiber core is significantly smaller than a multi mode cable core, it packs a real punch.

Beginning with the basics, our Singlemode LC to LC 9/125 Micron fiber optic cables are built to ensure that your network functions reliably.
