N7768A | N7768A 4-channel multimode optical attenuator

N7768A 4-channel multimode optical attenuator main features and technical specifications for optimal micro-fiber body modal transport distribution of built-in power monitoring feature helps to achieve power settings and stabilization precise wavelength range: 800 至 1370 nm attenuation range: 0 至 35 dB relative power monitoring Uncertainty: ± 0.1 dB + 300 pW up time: 200 ms typical conversion rate: Select the light path blocked from 0.1 to 80 and 1000 dB / s in:> 60 dB typical description of an optical attenuator It is used to test devices for flexible optical signal power control. Its main application is by measuring the BER with input signal power variation, determining the sensitivity of the optical receiver. N7766A and N7768A are respectively provided two or four attenuators for multimode fiber channel devices, and provides a 50 μm or 62.5 μm fiber ports. By monitoring the output power at any input power can achieve precise and stable power setting. Easy to use offset parameter, can set the power in accordance with the signal path testing device after other optical devices.
