Title:
OPTICAL TRANSMISSION/RECEPTION MODULE
Document Type and Number:
WIPO Patent Application WO/2010/079611
Kind Code:
A1
Abstract:
An optical transmission/reception module which can ensure the transmission quality without providing a collimating optical device and a narrow-band filter. A fiber (7) with a grating which has a function of the narrow-band filter to block transmission of an optical signal in a band other than a narrow band containing a wavelength of 1310 nm, a narrow band containing a wavelength of 1490 nm, and a narrow band containing a wavelength of 1550 nm is used as an optical fiber for transmitting an optical signal with the wavelength of 1310 nm that has passed through WDM filters (4, 5) to a station and transmitting optical signals with the wavelengths of 1490 nm and 1550 nm transmitted from the station to the WDM filter (5).
