We used two stainless steel coaxial cables and one telecommunication single-mode optical fiber to bring the microwave and the weak light (with the wavelength of
1550 nm) signals from room temperature to the sample plate, respectively.
Gaussian Optical Filter is used for filtering purpose with frequency corresponding to
1550 nm wavelength and bandwidth of 35 GHz.
The signal at 1520 nm has 25 mW of maximum power and the impact of self-phase modulation is critical for this signal, the cross phase modulation on the
1550 nm signal would be expensive.
Both VCSEL sources are operated at the same wavelength (
1550 nm) and the outputs of both VCSELs are combined in a 90[degrees] hybrid to produce the I/Q modulated optical OFDM signal.
In table (2) transporting of low bit rate 2.5 Gbps by using two RF modulations with the same optical wavelength (
1550 nm) to transmit through FSO, firstly by 20 GHz RF could operated longest distance compared with 60 GHz.

1550 nm using small mode field diameter Er:Yb co-doped double clad fiber in laser oscillator configuration," Laser Physics, vol.
Multiwavelength erbium-doped fiber (EDF) lasers operating in the third communications window, with wavelengths around
1550 nm, are very attractive today because of their different applications in telecommunications, fiber sensors, and spectroscopy [1,2].
The thulium fiber laser with a 1927 nm wavelength, for example, has roughly 10 times the absorption in skin compared to erbium fiber
1550 nm wavelength lasers.
In this paper, we have designed an ultraflat dispersion PCF based on square-lattice geometry with the inner air-hole ring infiltrated with a liquid of certain refractive indices around the C-band of wavelength with the first zero dispersion wavelength (ZDW) around
1550 nm. The numerical study shows that the proposed fibers can generate around 350 nm of flattened broadband SC generation in the IR wavelength ranging from 1375 nm to 1725 nm with less than a meter long of the fiber.
