计算机专业英语的一小段课文。急用,哪位好心人帮忙译一下!
Multimode Fiber
A type of fiber mostly used for shorter, e.g. campus distances.
It can easily carry 100 megabits/second for typical campus distances, with the maximum speed dependent upon the protocol used.
The entire Media Lab is cabled with multimode fiber.
Single-Mode Fiber
A type of fiber optic cable in which there is only one mode for the light to follow , thereby minimizing dispersion (smearing in the time domain). Single Mode is mainly used for long runs(>10km)and fed with lasers. It is more difficult to splice and patch than Multimode Fiber ,but its limit on (speed ×distance) is higher.
FDDI ,Fiber Distributed Data Interface
A LAN data-link protocol with a nominal 100 megabits/second data rate .FDDI is a point-to-point protocol ,but is usually used in a token-ring arrangement (SAS) or dual token ring (DAS) configuration
