Abstract
An optical transceiver for the coherent communication system is disclosed. The optical transceiver follows the standard of the CFP transceiver and installs a wavelength tunable laser diode (LD) as a light source for the optical transmission and a local light for the optical reception; an optical modulator of the Mach-Zehnder type made of dielectric material; and an optical receiver to recover the DP-QPSK optical signal. The housing of the optical transceiver provides a front auxiliary area and a rear auxiliary area to install a slender optical modulator and to bend an inner fiber with a large radius.
