JDSU 10Gb/s 光强度调制器
The JDSU 10 Gb/s Integrated Amplitude Modulator with Attenuator provides intrinsic attenuation flexibility for multichannel systems.The module employs an integrated attenuator that allows pre-emphasis of all International Telecommunications Union (ITU) wavelengths in a dense wavelength pision multiplexing (DWDM) optical link.The 10 Gb/s Integrated Amplitude Modulator with Attenuator is supplied in a mini package and qualifies to Telcordia GR-468-CORE. JDSU assures high reliability and performance at all times.
