Abstract: The present invention proposes a wavelength division multiplexing-passive optical network (WDM-PON) system which transmits downstream data to an optical network unit (ONU) as an optical line termination (OLT) receives seed light from a spectrum-sliced external light source module. One characteristic of the proposed WDM-PON system is that optical transmitters of the OLT and ONU are operated regardless of optical wavelength. Another characteristic of the proposed WDM-PON system is that a conventional TDMA-PON (E-PON or G-PON) ONU can be accommodated without a change.

Abstract: PURPOSE: An angled physical contact receptacle stub and an angled physical contact transmitter optical sub-assembly including the same are provided to reduce package costs by improving optical align difficulty. CONSTITUTION: An angled physical contact receptacle stub(100) comprises a first angled physical contact stub(110) and a second angled physical contact stub(120) accepted into a receptacle(1100). One end surface of the first angled physical contact stub is ground in an angled physical contact shape. One end surface of the second angled physical contact stub is ground in an angled physical contact shape. The second angled physical contact stub is combined with the first angled physical contact stub.
