SDL 1430nm Raman Fiber Laser, 5W. (RL30-3032-000-143).
The RL30 opens up new opportunities in extending the reach of long-haul optical links. It can be used as a pump for distributed Raman amplification, where the transmission fiber itself acts as the gain medium. One very important benefit of Raman amplification is that it can be used over a wide range of wavelengths, rather than within a fixed wavelength region as with erbium-doped fiber technology.
The RL30 is a revolutionary step in high power pumping options for telecommunications. The pump system consists of a double-clad fiber laser, pumped by an array of our telecommunication qualified pump modules, followed by a Cascaded Raman Resonator that shifts the light from the fiber laser to the emission wavelength. The design features a fused glass construction for optimum reliability, with no free space optics or epoxies in the light path.
The 1430nm version of the RL30 can also be used as a high powered pump for standard Erbium Doped Fiber Amplifiers. In repeaterless submarine systems the RL30 can be used to pump submerged erbium-doped fiber gain blocks. The high power of the RL30 (2 W nominally) makes it ideal for “pump sharing architectures, where one high powered pump source is used for several erbium doped fiber gain blocks.
