ABSTRACT:
It is an object of this invention to provide a connection unit capable of improving transmission characteristics. The connection unit according to this invention is provided between a plurality of first optical fibers extending from an optical amplifier and a plurality of second optical fibers in an optical cable, and comprises one or more optical components to connect one first optical fiber to one second optical fiber. Each of the optical components includes third and fourth optical fibers that can be connected to one first optical fiber and one second optical fiber with low connection losses, respectively, and a loss adjusting section for adjusting a transmission loss. The transmission loss deviation in a plurality of optical transmission lines is adjusted to 0.005 dB/km or less.
