An optical isolator is a passive magneto-optic device that makes travel of light unidirectionally. The operation of the device is based on the Faraday effect. It is used in applications to avoid unwanted feedback to the system using the optical isolator. Optical isolators are also known as optoisolators, optocouplers and photocouplers.
A cold site is a business location that is used for backup in the event of a disruptive operational disaster at the normal business site. A cold site is an office, but it does not always have the necessary equipment to resume prompt operations. The business paying for the cold site provides and installs this equipment.
A cold site is hosted by a third party, and services may be paid annually or monthly via a service charge.
