Abstract: The present disclosure relates to a communication line and a communication system using the same. The communication line according to an embodiment of the present disclosure includes a core portion that extends in a longitudinal direction and has a circular cross section, one or more ribs formed to extend from an outer surface of the core portion, a shielding portion that is connected to the rib, is formed to surround the core portion, and has at least one slit formed in the longitudinal direction, and a cover portion configured to cover the slit.

Abstract: The present invention relates to a communication line and a communication system. The communication line according to an embodiment of the present invention includes a dielectric portion that extends in a longitudinal direction and transmits a first signal received at one end thereof to the other end thereof, and at least one conductor portion that extends in the longitudinal direction of the dielectric portion and transmits a second signal received at one end thereof to the other end thereof.

Abstract: The present invention relates to a communication line. The communication line according to an embodiment of the present invention includes at least one core portion including a dielectric core extending in a longitudinal direction and a rib member formed on an outer surface of the dielectric core, and a shielding portion including a shielding having a hollow tubular shape and a rail member formed to extend on an inner surface of the shielding and extending along the shielding in the longitudinal direction, wherein the at least one core portion is inserted into the shielding portion.

Abstract: The present invention relates to a communication line. The communication line according to an embodiment of the present invention includes a shielding portion including a shielding having a hollow tubular shape, a core portion including a dielectric core that is located inside the shielding portion and extends in a longitudinal direction, and one rib that is located between the shielding portion and the core portion and connects the shielding portion and the core portion.

Abstract: Provided are an apparatus for compensating for the characteristics of a laser diode and an optical transmitter including the apparatus. The apparatus includes: an optical output detector which detects an optical power output from the laser diode and converts the optical power into a voltage; a bias current controller which detects a maximum level of the voltage and outputs a first control value corresponding to a difference between the maximum level and a first reference voltage; a modulation current controller which detects a minimum level of the voltage and outputs a second control value corresponding to a difference between the minimum level and a second reference voltage; and a laser diode driver which outputs a drive current to the laser diode according to the first and second control values.

Abstract: A burst mode optical receiver includes: a photodiode which converts an input optical signal into a current signal; a pre-amplifier which converts the current signal into a voltage signal; a single-to-differential converter which converts the single voltage signal output from the pre-amplifier into differential signals; a post amplifier which amplifies the differential signals and cancels an offset occurring during the amplification or offsets inherited from the differential signals; and a discriminator which discriminates data from the differential signals.
