The SVA-1 is a portable variable attenuator capable of providing attenuation at both 1310nm and 1550nm wavelengths. It is designed for ease of operation, offering both coarse and fine adjustment modes within a 60dB range while maintaining low insertion and return loss. The SVA-1 is compatible with all single-mode fibers and can be used in telecommunications networks, local area networks, video systems, and cable TV.
