Keysight (Agilent) 8156A Optical Attenuator Mainframe

The HP 8156A Optical Attenuator can be used in both single- and multimode applications. Each optical attenuator is calibrated over its entire 60 dB range at 1310 and 1550 nm. In addition, wavelength characteristics of the instrument are stored in an EEPROM. This allows an automatic correction to be performed for every wavelength and attenuation setting. The Agilent 8156A enables you to attenuate any optical signal up to 60 dB in precise steps over its entire wavelength range. A resolution of 0.001 dB lets you achieve the exact signal power required for your measurement with a repeatability of better than 0.005 dB. Maximum input power is +23 dBm. The Agilent 8156A is available with three different return loss options ranging from 35 dB to 60 dB. The HP 8156A can be used as calibrated and programmable back reflector to check the increase in bit error rate or noise performance as a function of the back reflection level. During your bit error rate measurements you may want to monitor the power level at the receiver input. Instead of using a separate coupler, the HP 8156A offers a built-in 13 dB coupler as an option. Specifications. Attenuation range is 60 dB with 0.001 dB resolution. Wavelength: 1200 nm to 1650 nm. Fiber type: 9/125 µm SM (opt. 100, 101, 121, 201, 221), 50/125 µm MM (opt. 350).

*This is a Web introductory price for one calibration of the Keysight (Agilent) 8156A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Extinction Ratio (ER)
Extinction Ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, (example a laser diode), where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage.

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.

Wavelength Repeatability
Wavelength Repeatability is the random uncertainty in reproducing a wavelength after detuning and re-setting the wavelength. The wavelength repeatability is ± half the span between the maximum and the minimum value of all actual values of these wavelengths. Example test condition: uninterrupted TLS output power, constant power level, temperature within operating temperature range, coherence control off, short time span. Note: NOTE The long-term wavelength repeatability can be obtained by taken the wavelength repeatability and wavelength stability into account.
