Dark Fiber vs Lit Fiber

There are a few advantages and disadvantages for picking either dark fiber vs lit fiber. 

Dark Fiber is just a length of fiber optic link which has no hardware associated with it and isn't transmitting any information. A business will rent or purchase this fiber from a system supplier and afterward completely deal with the gear, sending, security, traffic and support themselves.

As opposed to this picking a 'lit' alternative puts the onus on the system supplier who will at that point be answerable for keeping the fiber lit and guaranteeing availability and limit. Lit administrations like Ethernet, Managed Wavelengths of Optical administrations frequently accompany a Service Level Agreement (SLA) which guarantees the business a specific degree of availability and backing – up to 99.99%. Limit across lit fiber can scale from 1Gbps to 100Gpbs with even some fast 200Gbps across either standard or committed wavelengths.

Dark Fiber limit is boundless and is effectively adaptable. As the entire fiber is rented by and devoted completely to that business, it implies they utilize the limit how they pick. That incorporates exploiting innovation like Dense Wave Multiplex Divisioning (DWDM) where hardware toward the finish of the fiber can split the light out in to the different wavelengths of the range to convey information and expanding limit altogether – up to 400Gbps over a solitary fiber utilizing 80 channels.

Dark Fiber and Lit Fiber offer organizations altogether different alternatives, so it is imperative to think about what is generally critical to your business – regardless of whether that is cost, various directing, committed data transfer capacity and the sort of levels of limit and whether it will require scaling later on.
