Which of the following Fibre Channel cables are used for transmissions distances of up to 10 Km?
A.
Multimode cable.
B.
Single-mode cable
C.
Duplex cable
D.
Simplex cable
Explanation:
Single-mode cable is are for longer-distance applications as it has a greater transmission distance and is more expensive than multimode cable.
Incorrect Answers:
A: Multimode cable is the more common Fibre Channel cable and is used for short distance connections spanning over few meters.
C: Duplex cable allows for simultaneous, bidirectional data transfers. This allows devices to send and receive data simultaneously. They do not affect the distance of the cable. Furthermore, multimode duplex cable, as well as single-mode duplex cable is available.
D: Simplex cable consists of a single fiber that allows only one-way data transfers. Like duplex cable, they do not affect the distance of the cable and both multimode simplex cable, as well as single-mode simplex cable is available.
