Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Ralph’s company has expanded to include an additional building on the far end of the corporate campus, approximately 4 kilometers away from the building housing the datacenter. A single-mode fiber-optic cable connection has been installed between the new building and the datacenter for a 1000Base-BX10 connection, but the cable is not yet connected to a transceiver at the datacenter end. Noticing that there is a 1000Base-SX transceiver module in the datacenter storeroom, Ralph is wondering if he could use this on the new cable run. Which of the following are reasons why this might not work? (Choose all that apply.)
A
Transceiver mismatch
B
Incorrect cable type
C
Excessive cable length
D
Wavelength mismatch
Explanation: 

Detailed explanation-1: -Fiber-optic cables transmit data via fast-traveling pulses of light. Another layer of glass, called “cladding, ” is wrapped around the central fiber and causes light to repeatedly bounce off the walls of the cable rather than leak out at the edges, enabling the single to go farther without attenuation.

Detailed explanation-2: -Single mode works to transmit both long and short distances and does so regardless of the resolution of the device. A single mode fiber optic cable allows most devices to transmit more than six miles. Multimode fiber has a maximum distance of only about 1, 800 feet.

Detailed explanation-3: -FTTH (Fibre-to-the-Home): With this connection, broadband provides run the internet cable directly to the homes that help to offer fastest internet speed round the clock with strong connectivity. FTTB (Fiber to the Building/Basement): This connection does not run cable directly to user’s living space.
