Abstract:
This paper describes the design of our 2.5 Gb/s electro-absorption modulator integrated laser (EML) optical transmitter and its transmission in the long-haul wavelength division multiplexing (WDM) system with an erbium-doped fiber amplifier (EDFA). The experimental results of multi-channel data transmission over 160-km standard single mode fiber (SSMF) successfully demonstrate the bit error rate (BER) well below 10-9 and power penalty within the standard limit...
Excerpt:
Our chosen demultiplexer functions as follows. The optical circulator (from Agiltron Inc.) will rotate light entering at one port to exit at the next port. For instance, all three lights input at port 1 will exit at port 2. Next, the FBG (from Photronix Technologies) will reflect light that has its wavelength within 1551.67 0.25 nm range...
