bias-free modulator with integral optical fiber attenuators Oct 22, 2009

bias-free modulator with integral attenuator combines a modulator and a 20 dB variable attenuator within one small-outline package, simplifying component count and fiber splicing.

bias-free modulator with integral fiber optic attenuators combines a modulator and a 20 dB variable attenuator within one small-outline package, simplifying component count and fiber splicing. The bias point of the interferometer is set to operate at about the half-intensity point.Used with other passive equipment like fiber optic adapters and fiber optic splitters,the modulator provides superior signal quality over a wide range of wavelengths in the C and L bands, and can be used to modulate tunable lasers.These devices are used for 2.5Gb/s modulation and dynamic power leveling in DWDM systems.
