【摘要】 采用两只1×8单模光纤耦合器，实现了8×2．5Gbit／s时分复用信号的产生。光源采用TSL－210型可调谐主动销模激光器，脉冲周期为400ps（2．5Gbit／s），脉冲半宽为32ps。实验结果表明，这一时分复用信号产生方案具有输出脉冲的间隔和幅度易于调节、成本低、易于实验室拉制且制作方便等优点，对较窄脉宽的脉冲源能较方便地根据需要提高其脉冲重复率，不失为一种切实可行的时分复用信号产生方案。更多还原

【Abstract】 An 8×2. 5 Gbit/s optical time division multiplexing signal generating system has been achieved by using two 1×8 single-mode fiber couplers. Optical pulse source is TSL-210 active mode-locked laser with tunable wavelength, pulse period is 400 ps (2. 5 Gbit/s)and pulse half-width is 32 ps. Experimental results show that, this optical time division multiplexing signal generating scheme has advantages of easily adjusting for output pulse span and amplitude, low cost and easily fabrication, can be used to increase pulse repetition rate conveniently for narrow pulse width optical source according to our demands. Our results prove the feasibility of the scheme.更多还原
