A network technician has multimode fiber optic cable available in an existing IDF. Which of the following Ethernet standards should the technician use to connect the network switch to the existing fiber?
Given the availability of multimode fiber optic cable in the existing Intermediate Distribution Frame (IDF), the correct Ethernet standard to use is one that supports multimode fiber optic connections.
The options provided are:
A. 10GBaseT: This standard is designed for twisted-pair copper cabling and supports 10 Gbps Ethernet over copper, not fiber optics.
B. 1000BaseT: This standard is also for twisted-pair copper cabling and supports 1 Gbps Ethernet over copper, not fiber optics.
C. 1000BaseSX: This standard is specifically designed for multimode fiber optic cabling and supports 1 Gbps Ethernet over such fiber.
Therefore, the correct answer is:
C. 1000BaseSX
1000BASE-SX is a fiber optic Gigabit Ethernet standard for operation over multi-mode fiber using a 770 to 860 nanometer, near infrared (NIR) light wavelength. The standard specifies a distance capability between 220 meters and 550 meters
