چکیده
Multiple wavelength channels can be used for implementing transceiver modules in optical transmission system network in order to increase spectral efficiency. However, it leads to cost increment which is caused by employment of multiple optical components. Therefore, implementation of advanced modulation format has become an option to further increase spectral efficiency. But apparently, it involves complicated and costly transmission system. Carrierless amplitude and phase (CAP) modulation has emerged as promising advanced modulation format candidate in optical transmission system due to spectral efficiency improvement ability with reduction of optical transceiver complexity and cost. In this paper, we propose a transmission of 2.5 Gb/s CAP-4 and CAP-16 modulation formats over single mode fiber (SMF) link using 1550 nm vertical cavity surface emitting laser(VCSEL) with 2.5 Gbaud modulation rate. The signal is successfully recovered after 35 km of SMF in system of 10 GHz sample rate.
